Welcome to the Kubernetes API. You can use the Kubernetes API to read and write Kubernetes resource objects via a Kubernetes API endpoint.
This is a high-level overview of the basic types of resources provide by the Kubernetes API and their primary functions.
Workloads are objects you use to manage and run your containers on the cluster.
Discovery & LB resources are objects you use to "stitch" your workloads together into an externally accessible, load-balanced Service.
Config & Storage resources are objects you use to inject initialization data into your applications, and to persist data that is external to your container.
Cluster resources objects define how the cluster itself is configured; these are typically used only by cluster operators.
Metadata resources are objects you use to configure the behavior of other resources within the cluster, such as HorizontalPodAutoscaler
for scaling workloads.
Resource objects typically have 3 components:
Most resources provide the following Operations:
Create operations will create the resource in the storage backend. After a resource is create the system will apply the desired state.
Updates come in 2 forms: Replace and Patch:
ConfigMap
or Secret
resource will not result in all Pods seeing the changes unless the Pods are
restarted out of band.Reads come in 3 forms: Get, List and Watch:
Delete will delete a resource. Depending on the specific resource, child objects may or may not be garbage collected by the server. See notes on specific resource objects for details.
Resources may define additional operations specific to that resource type.
The API Groups and their versions are summarized in the following table.

Workloads resources are responsible for managing and running your containers on the cluster. Containers are created by Controllers through Pods. Pods run Containers and provide environmental dependencies such as shared or persistent storage Volumes and Configuration or Secret data injected into the container.
The most common Controllers are:
name: nginx
# Run the nginx:1.14 image
image: nginx:1.14
Group | Version | Kind |
---|---|---|
core | v1 | Container |
Warning:
Containers are only ever created within the context of a Pod. This is usually done using a Controller. See Controllers: Deployment, Job, or StatefulSet
Field | Description |
---|---|
args string array | Arguments to the entrypoint. The container image's CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell |
command string array | Entrypoint array. Not executed within a shell. The container image's ENTRYPOINT is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell |
env EnvVar array patch strategy: merge patch merge key: name | List of environment variables to set in the container. Cannot be updated. |
envFrom EnvFromSource array | List of sources to populate environment variables in the container. The keys defined within a source must be a C_IDENTIFIER. All invalid keys will be reported as an event when the container is starting. When a key exists in multiple sources, the value associated with the last source will take precedence. Values defined by an Env with a duplicate key will take precedence. Cannot be updated. |
image string | Container image name. More info: https://kubernetes.io/docs/concepts/containers/images This field is optional to allow higher level config management to default or override container images in workload controllers like Deployments and StatefulSets. |
imagePullPolicy string | Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images |
lifecycle Lifecycle | Actions that the management system should take in response to container lifecycle events. Cannot be updated. |
livenessProbe Probe | Periodic probe of container liveness. Container will be restarted if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
name string | Name of the container specified as a DNS_LABEL. Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated. |
ports ContainerPort array patch strategy: merge patch merge key: containerPort | List of ports to expose from the container. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255. Cannot be updated. |
readinessProbe Probe | 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 |
resources ResourceRequirements | Compute Resources required by this container. Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ |
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/ |
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 |
stdin boolean | Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. |
stdinOnce boolean | Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false |
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. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated. |
terminationMessagePolicy string | Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated. |
tty boolean | Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false. |
volumeDevices VolumeDevice array patch strategy: merge patch merge key: devicePath | volumeDevices is the list of block devices to be used by the container. |
volumeMounts VolumeMount array patch strategy: merge patch merge key: mountPath | Pod volumes to mount into the container's filesystem. Cannot be updated. |
workingDir string | Container's working directory. If not specified, the container runtime's default will be used, which might be configured in the container image. Cannot be updated. |
Field | Description |
---|---|
containerID string | Container's ID in the format ' |
image string | The image the container is running. More info: https://kubernetes.io/docs/concepts/containers/images. |
imageID string | ImageID of the container's image. |
lastState ContainerState | Details about the container's last termination condition. |
name string | This must be a DNS_LABEL. Each container in a pod must have a unique name. Cannot be updated. |
ready boolean | Specifies whether the container has passed its readiness probe. |
restartCount integer | The number of times the container has been restarted. |
started boolean | Specifies whether the container has passed its startup probe. Initialized as false, becomes true after startupProbe is considered successful. Resets to false when the container is restarted, or if kubelet loses state temporarily. Is always true when no startupProbe is defined. |
state ContainerState | Details about the container's current condition. |
Group | Version | Kind |

successfulJobsHistoryLimit integer | The number of successful finished jobs to retain. Value must be non-negative integer. Defaults to 3. |
suspend boolean | This flag tells the controller to suspend subsequent executions, it does not apply to already started executions. Defaults to false. |
timeZone string | The time zone name for the given schedule, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones. If not specified, this will default to the time zone of the kube-controller-manager process. The set of valid time zone names and the time zone offset is loaded from the system-wide time zone database by the API server during CronJob validation and the controller manager during execution. If no system-wide time zone database can be found a bundled version of the database is used instead. If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host configuration, the controller will stop creating new new Jobs and will create a system event with the reason UnknownTimeZone.

Parameter | Description |
---|---|
pretty | If 'true', then the output is pretty printed. |
continue | The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. |
dryRun | When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
fieldSelector | A selector to restrict the list of returned objects by their fields. Defaults to everything. |
gracePeriodSeconds | The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately. |
labelSelector | A selector to restrict the list of returned objects by their labels. Defaults to everything. |
limit | limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. |
orphanDependents | Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both. |
propagationPolicy | Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground. |
resourceVersion | resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
resourceVersionMatch | resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
timeoutSeconds | Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. |

Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. |
fieldSelector | A selector to restrict the list of returned objects by their fields. Defaults to everything. |
labelSelector | A selector to restrict the list of returned objects by their labels. Defaults to everything. |
limit | limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. |
pretty | If 'true', then the output is pretty printed. |
resourceVersion | resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
resourceVersionMatch | resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
timeoutSeconds | Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. |
watch | Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion. |

allowWatchBookmarks | allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. |
continue | The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

dryRun | When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
fieldManager | fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch). |
fieldValidation | fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the `ServerSideFieldValidation` feature gate is also enabled. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23 and is the default behavior when the `ServerSideFieldValidation` feature gate is disabled. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default when the `ServerSideFieldValidation` feature gate is enabled. - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
