import "k8s.io/api/core/v1"

Pod

Pod is a collection of containers that can run on a host. This resource is created by clients and scheduled onto hosts.

PodSpec

PodSpec is a description of a pod.

Containers

  • containers ([]Container), required

    Patch strategy: merge on key name

    List of containers belonging to the pod. Containers cannot currently be added or removed. There must be at least one container in a Pod. Cannot be updated.

  • initContainers ([]Container)

    Patch strategy: merge on key name

    List of initialization containers belonging to the pod. Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

  • imagePullSecrets ([]LocalObjectReference)

    Patch strategy: merge on key name

    ImagePullSecrets is an optional list of references to secrets in the same namespace to use for pulling any of the images used by this PodSpec. If specified, these secrets will be passed to individual puller implementations for them to use. For example, in the case of docker, only DockerConfig type secrets are honored. More info: https://kubernetes.io/docs/concepts/containers/images#specifying-imagepullsecrets-on-a-pod

  • enableServiceLinks (boolean)

    EnableServiceLinks indicates whether information about services should be injected into pod's environment variables, matching the syntax of Docker links. Optional: Defaults to true.

Volumes

Scheduling

  • nodeSelector (map[string]string)

    NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/

  • nodeName (string)

    NodeName is a request to schedule this pod onto a specific node. If it is non-empty, the scheduler simply schedules this pod onto that node, assuming that it fits resource requirements.

  • affinity (Affinity)

    If specified, the pod's scheduling constraints

    Affinity is a group of affinity scheduling rules.

    • affinity.nodeAffinity (NodeAffinity)

      Describes node affinity scheduling rules for the pod.

    • affinity.podAffinity (PodAffinity)

      Describes pod affinity scheduling rules (e.g. co-locate this pod in the same node, zone, etc. as some other pod(s)).

    • affinity.podAntiAffinity (PodAntiAffinity)

      Describes pod anti-affinity scheduling rules (e.g. avoid putting this pod in the same node, zone, etc. as some other pod(s)).

  • tolerations ([]Toleration)

    If specified, the pod's tolerations.

    The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .

    • tolerations.key (string)

      Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

    • tolerations.operator (string)

      Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

    • tolerations.value (string)

      Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

    • tolerations.effect (string)

      Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

    • tolerations.tolerationSeconds (int64)

      TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

  • schedulerName (string)

    If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler.

  • runtimeClassName (string)

    RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/585-runtime-class This is a beta feature as of Kubernetes v1.14.

  • priorityClassName (string)

    If specified, indicates the pod's priority. "system-node-critical" and "system-cluster-critical" are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.

  • priority (int32)

    The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.

  • topologySpreadConstraints ([]TopologySpreadConstraint)

    Patch strategy: merge on key topologyKey

    Map: unique values on keys topologyKey, whenUnsatisfiable will be kept during a merge

    TopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed.

    TopologySpreadConstraint specifies how to spread matching pods among the given topology.

    • topologySpreadConstraints.maxSkew (int32), required

      MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 1/1/0: | zone1 | zone2 | zone3 | | P | P | | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 1/1/1; scheduling it onto zone1(zone2) would make the ActualSkew(2-0) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed.

    • topologySpreadConstraints.topologyKey (string), required

      TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. It's a required field.

    • topologySpreadConstraints.whenUnsatisfiable (string), required

      WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assigment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field.

    • topologySpreadConstraints.labelSelector (LabelSelector)

      LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.

    Restart policy for all containers within the pod. One of Always, OnFailure, Never. Default to Always. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#restart-policy

  • terminationGracePeriodSeconds (int64)

    Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. Defaults to 30 seconds.

  • activeDeadlineSeconds (int64)

    Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer.

  • readinessGates ([]PodReadinessGate)

    If specified, all readiness gates will be evaluated for pod readiness. A pod is ready when all its containers are ready AND all conditions specified in the readiness gates have status equal to "True" More info: https://git.k8s.io/enhancements/keps/sig-network/580-pod-readiness-gates

    PodReadinessGate contains the reference to a pod condition

    • readinessGates.conditionType (string), required

      ConditionType refers to a condition in the pod's condition list with matching type.

  • setHostnameAsFQDN (boolean)

    If true the pod's hostname will be configured as the pod's FQDN, rather than the leaf name (the default). In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. Default to false.

  • subdomain (string)

    If specified, the fully qualified Pod hostname will be "<hostname>.<subdomain>.<pod namespace>.svc.<cluster domain>". If not specified, the pod will not have a domainname at all.

        HostProcess determines if a container should be run as a 'Host Process' container. This field is alpha-level and will only be honored by components that enable the WindowsHostProcessContainers feature flag. Setting this field without the feature flag will result in errors when validating the Pod. All of a Pod's containers must have the same effective HostProcess value (it is not allowed to have a mix of HostProcess containers and non-HostProcess containers). In addition, if HostProcess is true then HostNetwork must also be set to true.

If the RuntimeClass admission controller is enabled, overhead must not be set in Pod create requests. The RuntimeClass admission controller will reject Pod create requests which have the overhead already set. If RuntimeClass is configured and selected in the PodSpec, Overhead will be set to the value defined in the corresponding RuntimeClass, otherwise it will remain unset and treated as zero. More info: https://git.k8s.io/enhancements/keps/sig-node/688-pod-overhead/README.md This field is beta-level as of Kubernetes v1.18, and is only honored by servers that enable the PodOverhead feature.

Resources

Lifecycle

  • lifecycle (Lifecycle)

    Actions that the management system should take in response to container lifecycle events. Cannot be updated.

    Lifecycle describes actions that the management system should take in response to container lifecycle events. For the PostStart and PreStop lifecycle handlers, management of the container blocks until the action is complete, unless the container process fails, in which case the handler is aborted.

    • lifecycle.postStart (Handler)

      PostStart is called immediately after a container is created. If the handler fails, the container is terminated and restarted according to its restart policy. Other management of the container blocks until the hook completes. More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks

    • lifecycle.preStop (Handler)

      PreStop is called immediately before a container is terminated due to an API request or management event such as liveness/startup probe failure, preemption, resource contention, etc. The handler is not called if the container crashes or exits. The reason for termination is passed to the handler. The Pod's termination grace period countdown begins before the PreStop hooked is executed. Regardless of the outcome of the handler, the container will eventually terminate within the Pod's termination grace period. Other management of the container blocks until the hook completes or until the termination grace period is reached. More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks

  • terminationMessagePath (string)

    Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem.

    Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

  • startupProbe (Probe)

    StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

Security Context

  • securityContext (SecurityContext)

    SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/

    SecurityContext holds security configuration that will be applied to a container. Some fields are present in both SecurityContext and PodSecurityContext. When both are set, the values in SecurityContext take precedence.

This field is alpha-level and will only be honored by components that enable the WindowsHostProcessContainers feature flag. Setting this field without the feature flag will result in errors when validating the Pod. All of a Pod's containers must have the same effective HostProcess value (it is not allowed to have a mix of HostProcess containers and non-HostProcess containers). In addition, if HostProcess is true then HostNetwork must also be set to true.

      • securityContext.windowsOptions.runAsUserName (string)

EphemeralContainer

An EphemeralContainer is a container that may be added temporarily to an existing pod for user-initiated activities such as debugging. Ephemeral containers have no resource or scheduling guarantees, and they will not be restarted when they exit or when a pod is removed or restarted. If an ephemeral container causes a pod to exceed its resource allocation, the pod may be evicted. Ephemeral containers may not be added by directly updating the pod spec. They must be added via the pod's ephemeralcontainers subresource, and they will appear in the pod spec once added. This is an alpha feature enabled by the EphemeralContainers feature flag.

  • name (string), required

    Name of the ephemeral container specified as a DNS_LABEL. This name must be unique among all containers, init containers and ephemeral containers.

Set this value longer than the expected cleanup time for your process. If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset.

    Pending: The pod has been accepted by the Kubernetes system, but one or more of the container images has not been created. This includes time before being scheduled as well as time spent downloading images over the network, which could take a while. Running: The pod has been bound to a node, and all of the containers have been created. At least one container is still running, or is in the process of starting or restarting. Succeeded: All containers in the pod have terminated in success, and will not be restarted. Failed: All containers in the pod have terminated, and at least one container has terminated in failure. The container either exited with non-zero status or was terminated by the system. Unknown: For some reason the state of the pod could not be obtained, typically due to an error in communicating with the host of the pod.

PodList

PodList is a list of Pods.

Operations

get read the specified Pod

HTTP Request

GET /api/v1/namespaces/{namespace}/pods/{name}

Parameters

  • name (in path): string, required

    name of the Pod

  • namespace (in path): string, required

    namespace

  • pretty (in query): string

    pretty

Response

200 (Pod): OK

401: Unauthorized

get read ephemeralcontainers of the specified Pod

HTTP Request

GET /api/v1/namespaces/{namespace}/pods/{name}/ephemeralcontainers

Parameters

  • name (in path): string, required

    name of the Pod

  • namespace (in path): string, required

    namespace

  • pretty (in query): string

    pretty

Response

200 (Pod): OK

401: Unauthorized

get read log of the specified Pod

HTTP Request

GET /api/v1/namespaces/{namespace}/pods/{name}/log

Parameters

  • name (in path): string, required

    name of the Pod

  • namespace (in path): string, required

    namespace

  • container (in query): string

    The container for which to stream logs. Defaults to only container if there is one container in the pod.

  • follow (in query): boolean

    Follow the log stream of the pod. Defaults to false.

  • insecureSkipTLSVerifyBackend (in query): boolean

    insecureSkipTLSVerifyBackend indicates that the apiserver should not confirm the validity of the serving certificate of the backend it is connecting to. This will make the HTTPS connection between the apiserver and the backend insecure. This means the apiserver cannot verify the log data it is receiving came from the real kubelet. If the kubelet is configured to verify the apiserver's TLS credentials, it does not mean the connection to the real kubelet is vulnerable to a man in the middle attack (e.g. an attacker could not intercept the actual log data coming from the real kubelet).

  • limitBytes (in query): integer

    If set, the number of bytes to read from the server before terminating the log output. This may not display a complete final line of logging, and may return slightly more or slightly less than the specified limit.

  • pretty (in query): string

    pretty

  • previous (in query): boolean

    Return previous terminated container logs. Defaults to false.

  • sinceSeconds (in query): integer

    A relative time in seconds before the current time from which to show logs. If this value precedes the time a pod was started, only logs since the pod start will be returned. If this value is in the future, no logs will be returned. Only one of sinceSeconds or sinceTime may be specified.

  • tailLines (in query): integer

    If set, the number of lines from the end of the logs to show. If not specified, logs are shown from the creation of the container or sinceSeconds or sinceTime

  • timestamps (in query): boolean

    If true, add an RFC3339 or RFC3339Nano timestamp at the beginning of every line of log output. Defaults to false.

Response

200 (string): OK

401: Unauthorized

5 - Deployment

Deployment enables declarative updates for Pods and ReplicaSets.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

Deployment

Deployment enables declarative updates for Pods and ReplicaSets.

DeploymentSpec

DeploymentSpec is the specification of the desired behavior of the Deployment.

  • selector (LabelSelector), required

    Label selector for pods. Existing ReplicaSets whose pods are selected by this will be the ones affected by this deployment. It must match the pod template's labels.

  • template (PodTemplateSpec), required

    Template describes the pods that will be created.

  • replicas (int32)

    Number of desired pods. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.

  • minReadySeconds (int32)

    Minimum number of seconds for which a newly created pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)

  • strategy (DeploymentStrategy)

    Patch strategy: retainKeys

    The deployment strategy to use to replace existing pods with new ones.

    DeploymentStrategy describes how to replace existing pods with new ones.

    • strategy.type (string)

      Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.

    • strategy.rollingUpdate (RollingUpdateDeployment)

      Rolling update config params. Present only if DeploymentStrategyType = RollingUpdate.

      Spec to control the desired behavior of rolling update.

      • strategy.rollingUpdate.maxSurge (IntOrString)

        The maximum number of pods that can be scheduled above the desired number of pods. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 25%. Example: when this is set to 30%, the new ReplicaSet can be scaled up immediately when the rolling update starts, such that the total number of old and new pods do not exceed 130% of desired pods. Once old pods have been killed, new ReplicaSet can be scaled up further, ensuring that total number of pods running at any time during the update is at most 130% of desired pods.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

      • strategy.rollingUpdate.maxUnavailable (IntOrString)

        The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 25%. Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old ReplicaSet can be scaled down further, followed by scaling up the new ReplicaSet, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

  • revisionHistoryLimit (int32)

    The number of old ReplicaSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

  • progressDeadlineSeconds (int32)

    The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s.

  • paused (boolean)

    Indicates that the deployment is paused.

DeploymentStatus

DeploymentStatus is the most recently observed status of the Deployment.

  • replicas (int32)

    Total number of non-terminated pods targeted by this deployment (their labels match the selector).

  • availableReplicas (int32)

    Total number of available pods (ready for at least minReadySeconds) targeted by this deployment.

  • readyReplicas (int32)

    Total number of ready pods targeted by this deployment.

  • unavailableReplicas (int32)

    Total number of unavailable pods targeted by this deployment. This is the total number of pods that are still required for the deployment to have 100% available capacity. They may either be pods that are running but not yet available or pods that still have not been created.

  • updatedReplicas (int32)

    Total number of non-terminated pods targeted by this deployment that have the desired template spec.

  • collisionCount (int32)

    Count of hash collisions for the Deployment. The Deployment controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ReplicaSet.

  • conditions ([]DeploymentCondition)

    Patch strategy: merge on key type

    Represents the latest available observations of a deployment's current state.

    DeploymentCondition describes the state of a deployment at a certain point.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of deployment condition.

    • conditions.lastTransitionTime (Time)

      Last time the condition transitioned from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.lastUpdateTime (Time)

      The last time this condition was updated.

6 - StatefulSet

StatefulSet represents a set of pods with consistent identities.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

StatefulSet

StatefulSet represents a set of pods with consistent identities. Identities are defined as:

  • Network: A single stable DNS and hostname.
  • Storage: As many VolumeClaims as requested. The StatefulSet guarantees that a given network identity will always map to the same storage identity.

StatefulSetSpec

A StatefulSetSpec is the specification of a StatefulSet.

  • serviceName (string), required

    serviceName is the name of the service that governs this StatefulSet. This service must exist before the StatefulSet, and is responsible for the network identity of the set. Pods get DNS/hostnames that follow the pattern: pod-specific-string.serviceName.default.svc.cluster.local where "pod-specific-string" is managed by the StatefulSet controller.

  • selector (LabelSelector), required

    selector is a label query over pods that should match the replica count. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

  • template (PodTemplateSpec), required

    template is the object that describes the pod that will be created if insufficient replicas are detected. Each pod stamped out by the StatefulSet will fulfill this Template, but have a unique identity from the rest of the StatefulSet.

  • replicas (int32)

    replicas is the desired number of replicas of the given Template. These are replicas in the sense that they are instantiations of the same Template, but individual replicas also have a consistent identity. If unspecified, defaults to 1.

  • updateStrategy (StatefulSetUpdateStrategy)

    updateStrategy indicates the StatefulSetUpdateStrategy that will be employed to update Pods in the StatefulSet when a revision is made to Template.

    StatefulSetUpdateStrategy indicates the strategy that the StatefulSet controller will use to perform updates. It includes any additional parameters necessary to perform the update for the indicated strategy.

    • updateStrategy.type (string)

      Type indicates the type of the StatefulSetUpdateStrategy. Default is RollingUpdate.

    • updateStrategy.rollingUpdate (RollingUpdateStatefulSetStrategy)

      RollingUpdate is used to communicate parameters when Type is RollingUpdateStatefulSetStrategyType.

      RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType.

      • updateStrategy.rollingUpdate.partition (int32)

        Partition indicates the ordinal at which the StatefulSet should be partitioned. Default value is 0.

  • podManagementPolicy (string)

    podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down. The default policy is OrderedReady, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. When scaling down, the pods are removed in the opposite order. The alternative policy is Parallel which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once.

  • revisionHistoryLimit (int32)

    revisionHistoryLimit is the maximum number of revisions that will be maintained in the StatefulSet's revision history. The revision history consists of all revisions not represented by a currently applied StatefulSetSpec version. The default value is 10.

  • volumeClaimTemplates ([]PersistentVolumeClaim)

    volumeClaimTemplates is a list of claims that pods are allowed to reference. The StatefulSet controller is responsible for mapping network identities to claims in a way that maintains the identity of a pod. Every claim in this list must have at least one matching (by name) volumeMount in one container in the template. A claim in this list takes precedence over any volumes in the template, with the same name.

  • minReadySeconds (int32)

    Minimum number of seconds for which a newly created pod should be ready without any of its container crashing for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready) This is an alpha field and requires enabling StatefulSetMinReadySeconds feature gate.

StatefulSetStatus

StatefulSetStatus represents the current state of a StatefulSet.

  • replicas (int32), required

    replicas is the number of Pods created by the StatefulSet controller.

  • readyReplicas (int32)

    readyReplicas is the number of Pods created by the StatefulSet controller that have a Ready Condition.

  • currentReplicas (int32)

    currentReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by currentRevision.

  • updatedReplicas (int32)

    updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by updateRevision.

  • availableReplicas (int32)

    Total number of available pods (ready for at least minReadySeconds) targeted by this statefulset. This is an alpha field and requires enabling StatefulSetMinReadySeconds feature gate. Remove omitempty when graduating to beta

  • collisionCount (int32)

    collisionCount is the count of hash collisions for the StatefulSet. The StatefulSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.

  • conditions ([]StatefulSetCondition)

    Patch strategy: merge on key type

    Represents the latest available observations of a statefulset's current state.

    StatefulSetCondition describes the state of a statefulset at a certain point.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of statefulset condition.

    • conditions.lastTransitionTime (Time)

      Last time the condition transitioned from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      A human readable message indicating details about the transition.

    • conditions.reason (string)

      The reason for the condition's last transition.

  • currentRevision (string)

    currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [0,currentReplicas).

  • updateRevision (string)

    updateRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [replicas-updatedReplicas,replicas)

  • observedGeneration (int64)

    observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the StatefulSet's generation, which is updated on mutation by the API Server.

7 - ControllerRevision

ControllerRevision implements an immutable snapshot of state data.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

ControllerRevision

ControllerRevision implements an immutable snapshot of state data. Clients are responsible for serializing and deserializing the objects that contain their internal state. Once a ControllerRevision has been successfully created, it can not be updated. The API Server will fail validation of all requests that attempt to mutate the Data field. ControllerRevisions may, however, be deleted. Note that, due to its use by both the DaemonSet and StatefulSet controllers for update and rollback, this object is beta. However, it may be subject to name and representation changes in future releases, and clients should not depend on its stability. It is primarily for internal use by controllers.

  • apiVersion: apps/v1

  • kind: ControllerRevision

  • metadata (ObjectMeta)

    Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • revision (int64), required

    Revision indicates the revision of the state represented by Data.

  • data (RawExtension)

    Data is the serialized representation of the state.

    *RawExtension is used to hold extensions in external versions.

    To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

    // Internal package: type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.Object json:"myPlugin" } type PluginA struct { AOption string json:"aOption" }

    // External package: type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.RawExtension json:"myPlugin" } type PluginA struct { AOption string json:"aOption" }

    // On the wire, the JSON will look something like this: { "kind":"MyAPIObject", "apiVersion":"v1", "myPlugin": { "kind":"PluginA", "aOption":"foo", }, }

    So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*

8 - DaemonSet

DaemonSet represents the configuration of a daemon set.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

DaemonSet

DaemonSet represents the configuration of a daemon set.

DaemonSetSpec

DaemonSetSpec is the specification of a daemon set.

  • selector (LabelSelector), required

    A label query over pods that are managed by the daemon set. Must match in order to be controlled. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

  • template (PodTemplateSpec), required

    An object that describes the pod that will be created. The DaemonSet will create exactly one copy of this pod on every node that matches the template's node selector (or on every node if no node selector is specified). More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#pod-template

  • minReadySeconds (int32)

    The minimum number of seconds for which a newly created DaemonSet pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready).

  • updateStrategy (DaemonSetUpdateStrategy)

    An update strategy to replace existing DaemonSet pods with new pods.

    DaemonSetUpdateStrategy is a struct used to control the update strategy for a DaemonSet.

    • updateStrategy.type (string)

      Type of daemon set update. Can be "RollingUpdate" or "OnDelete". Default is RollingUpdate.

    • updateStrategy.rollingUpdate (RollingUpdateDaemonSet)

      Rolling update config params. Present only if type = "RollingUpdate".

      Spec to control the desired behavior of daemon set rolling update.

      • updateStrategy.rollingUpdate.maxSurge (IntOrString)

        The maximum number of nodes with an existing available DaemonSet pod that can have an updated DaemonSet pod during during an update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up to a minimum of 1. Default value is 0. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their a new pod created before the old pod is marked as deleted. The update starts by launching new pods on 30% of nodes. Once an updated pod is available (Ready for at least minReadySeconds) the old DaemonSet pod on that node is marked deleted. If the old pod becomes unavailable for any reason (Ready transitions to false, is evicted, or is drained) an updated pod is immediatedly created on that node without considering surge limits. Allowing surge implies the possibility that the resources consumed by the daemonset on any given node can double if the readiness check fails, and so resource intensive daemonsets should take into account that they may cause evictions during disruption. This is beta field and enabled/disabled by DaemonSetUpdateSurge feature gate.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

      • updateStrategy.rollingUpdate.maxUnavailable (IntOrString)

        The maximum number of DaemonSet pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of total number of DaemonSet pods at the start of the update (ex: 10%). Absolute number is calculated from percentage by rounding up. This cannot be 0 if MaxSurge is 0 Default value is 1. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their pods stopped for an update at any given time. The update starts by stopping at most 30% of those DaemonSet pods and then brings up new DaemonSet pods in their place. Once the new pods are available, it then proceeds onto other DaemonSet pods, thus ensuring that at least 70% of original number of DaemonSet pods are available at all times during the update.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

  • revisionHistoryLimit (int32)

    The number of old history to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

DaemonSetStatus

DaemonSetStatus represents the current status of a daemon set.

  • numberReady (int32), required

    The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and ready.

  • numberAvailable (int32)

    The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and available (ready for at least spec.minReadySeconds)

  • numberUnavailable (int32)

    The number of nodes that should be running the daemon pod and have none of the daemon pod running and available (ready for at least spec.minReadySeconds)

  • numberMisscheduled (int32), required

    The number of nodes that are running the daemon pod, but are not supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • desiredNumberScheduled (int32), required

    The total number of nodes that should be running the daemon pod (including nodes correctly running the daemon pod). More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • currentNumberScheduled (int32), required

    The number of nodes that are running at least 1 daemon pod and are supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • updatedNumberScheduled (int32)

    The total number of nodes that are running updated daemon pod

  • collisionCount (int32)

    Count of hash collisions for the DaemonSet. The DaemonSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.

  • conditions ([]DaemonSetCondition)

    Patch strategy: merge on key type

    Represents the latest available observations of a DaemonSet's current state.

    DaemonSetCondition describes the state of a DaemonSet at a certain point.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of DaemonSet condition.

    • conditions.lastTransitionTime (Time)

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      A human readable message indicating details about the transition.

    • conditions.reason (string)

      The reason for the condition's last transition.

  • observedGeneration (int64)

    The most recent generation observed by the daemon set controller.

9 - Job

Job represents the configuration of a single job.

apiVersion: batch/v1

import "k8s.io/api/batch/v1"

Job

Job represents the configuration of a single job.

JobSpec

JobSpec describes how the job execution will look like.

Replicas

Lifecycle

  • completions (int32)

    Specifies the desired number of successfully finished pods the job should be run with. Setting to nil means that the success of any pod signals the success of all pods, and allows parallelism to have any positive value. Setting to 1 means that parallelism is limited to 1 and the success of that pod signals the success of the job. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

  • completionMode (string)

    CompletionMode specifies how Pod completions are tracked. It can be NonIndexed (default) or Indexed.

    NonIndexed means that the Job is considered complete when there have been .spec.completions successfully completed Pods. Each Pod completion is homologous to each other.

    Indexed means that the Pods of a Job get an associated completion index from 0 to (.spec.completions - 1), available in the annotation batch.kubernetes.io/job-completion-index. The Job is considered complete when there is one successfully completed Pod for each index. When value is Indexed, .spec.completions must be specified and .spec.parallelism must be less than or equal to 10^5. In addition, The Pod name takes the form $(job-name)-$(index)-$(random-string), the Pod hostname takes the form $(job-name)-$(index).

    This field is beta-level. More completion modes can be added in the future. If the Job controller observes a mode that it doesn't recognize, the controller skips updates for the Job.

  • backoffLimit (int32)

    Specifies the number of retries before marking this job failed. Defaults to 6

  • activeDeadlineSeconds (int64)

    Specifies the duration in seconds relative to the startTime that the job may be continuously active before the system tries to terminate it; value must be positive integer. If a Job is suspended (at creation or through an update), this timer will effectively be stopped and reset when the Job is resumed again.

  • ttlSecondsAfterFinished (int32)

    ttlSecondsAfterFinished limits the lifetime of a Job that has finished execution (either Complete or Failed). If this field is set, ttlSecondsAfterFinished after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is unset, the Job won't be automatically deleted. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes. This field is alpha-level and is only honored by servers that enable the TTLAfterFinished feature.

  • suspend (boolean)

    Suspend specifies whether the Job controller should create Pods or not. If a Job is created with suspend set to true, no Pods are created by the Job controller. If a Job is suspended after creation (i.e. the flag goes from false to true), the Job controller will delete all active Pods associated with this Job. Users must design their workload to gracefully handle this. Suspending a Job will reset the StartTime field of the Job, effectively resetting the ActiveDeadlineSeconds timer too. Defaults to false.

    This field is beta-level, gated by SuspendJob feature flag (enabled by default).

Selector

JobStatus

JobStatus represents the current state of a Job.

  • startTime (Time)

    Represents time when the job controller started processing a job. When a Job is created in the suspended state, this field is not set until the first time it is resumed. This field is reset every time a Job is resumed from suspension. It is represented in RFC3339 form and is in UTC.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

  • completionTime (Time)

    Represents time when the job was completed. It is not guaranteed to be set in happens-before order across separate operations. It is represented in RFC3339 form and is in UTC. The completion time is only set when the job finishes successfully.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

  • active (int32)

    The number of actively running pods.

  • failed (int32)

    The number of pods which reached phase Failed.

  • succeeded (int32)

    The number of pods which reached phase Succeeded.

  • completedIndexes (string)

    CompletedIndexes holds the completed indexes when .spec.completionMode = "Indexed" in a text format. The indexes are represented as decimal integers separated by commas. The numbers are listed in increasing order. Three or more consecutive numbers are compressed and represented by the first and last element of the series, separated by a hyphen. For example, if the completed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7".

  • conditions ([]JobCondition)

    Patch strategy: merge on key type

    Atomic: will be replaced during a merge

    The latest available observations of an object's current state. When a Job fails, one of the conditions will have type "Failed" and status true. When a Job is suspended, one of the conditions will have type "Suspended" and status true; when the Job is resumed, the status of this condition will become false. When a Job is completed, one of the conditions will have type "Complete" and status true. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

    JobCondition describes current state of a job.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of job condition, Complete or Failed.

    • conditions.lastProbeTime (Time)

      Last time the condition was checked.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.lastTransitionTime (Time)

      Last time the condition transit from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      Human readable message indicating details about last transition.

    • conditions.reason (string)

      (brief) reason for the condition's last transition.

  • uncountedTerminatedPods (UncountedTerminatedPods)

    UncountedTerminatedPods holds the UIDs of Pods that have terminated but the job controller hasn't yet accounted for in the status counters.

    The job controller creates pods with a finalizer. When a pod terminates (succeeded or failed), the controller does three steps to account for it in the job status: (1) Add the pod UID to the arrays in this field. (2) Remove the pod finalizer. (3) Remove the pod UID from the arrays while increasing the corresponding counter.

    This field is alpha-level. The job controller only makes use of this field when the feature gate PodTrackingWithFinalizers is enabled. Old jobs might not be tracked using this field, in which case the field remains null.

    UncountedTerminatedPods holds UIDs of Pods that have terminated but haven't been accounted in Job status counters.

    • uncountedTerminatedPods.failed ([]string)

      Set: unique values will be kept during a merge

      Failed holds UIDs of failed Pods.

    • uncountedTerminatedPods.succeeded ([]string)

      Set: unique values will be kept during a merge

      Succeeded holds UIDs of succeeded Pods.

import "k8s.io/api/autoscaling/v2beta2"

HorizontalPodAutoscaler

HorizontalPodAutoscaler is the configuration for a horizontal pod autoscaler, which automatically manages the replica count of any resource implementing the scale subresource based on the metrics specified.

HorizontalPodAutoscalerSpec

HorizontalPodAutoscalerSpec describes the desired functionality of the HorizontalPodAutoscaler.

  • maxReplicas (int32), required

    maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas.

  • scaleTargetRef (CrossVersionObjectReference), required

    scaleTargetRef points to the target resource to scale, and is used to the pods for which metrics should be collected, as well as to actually change the replica count.

    CrossVersionObjectReference contains enough information to let you identify the referred resource.

  • minReplicas (int32)

    minReplicas is the lower limit for the number of replicas to which the autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured. Scaling is active as long as at least one metric value is available.

  • behavior (HorizontalPodAutoscalerBehavior)

    behavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively). If not set, the default HPAScalingRules for scale up and scale down are used.

    • behavior.scaleDown (HPAScalingRules)

      scaleDown is scaling policy for scaling Down. If not set, the default value is to allow to scale down to minReplicas pods, with a 300 second stabilization window (i.e., the highest recommendation for the last 300sec is used).

      HPAScalingRules configures the scaling behavior for one direction. These Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies.

      • behavior.scaleDown.selectPolicy (string)

        selectPolicy is used to specify which policy should be used. If not set, the default value MaxPolicySelect is used.

      • behavior.scaleDown.stabilizationWindowSeconds (int32)

        StabilizationWindowSeconds is the number of seconds for which past recommendations should be considered while scaling up or scaling down. StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour). If not set, use the default values: - For scale up: 0 (i.e. no stabilization is done). - For scale down: 300 (i.e. the stabilization window is 300 seconds long).

    • behavior.scaleUp (HPAScalingRules)

      scaleUp is scaling policy for scaling Up. If not set, the default value is the higher of:

      • increase no more than 4 pods per 60 seconds
      • double the number of pods per 60 seconds No stabilization is used.

  • metrics ([]MetricSpec)

    metrics contains the specifications for which to use to calculate the desired replica count (the maximum replica count across all metrics will be used). The desired replica count is calculated multiplying the ratio between the target value and the current value by the current number of pods. Ergo, metrics used must decrease as the pod count is increased, and vice-versa. See the individual metric source types for more information about how each type of metric must respond. If not set, the default metric will be set to 80% average CPU utilization.
