Properties

Optional Readonly args

args: string[]

Arguments to the entrypoint. The docker 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. The $(VAR_NAME) syntax can be escaped with a double $$, ie: $$(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

schema

io.k8s.api.core.v1.Container#args

Optional Readonly command

command: string[]

Entrypoint array. Not executed within a shell. The docker 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. The $(VAR_NAME) syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated.

io.k8s.api.core.v1.Container#command

Optional Readonly env

env: EnvVar[]

List of environment variables to set in the container. Cannot be updated.

schema

io.k8s.api.core.v1.Container#env

Optional Readonly envFrom

envFrom: EnvFromSource[]

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.

schema

io.k8s.api.core.v1.Container#envFrom

Optional Readonly image

image: string

Docker 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.

schema

io.k8s.api.core.v1.Container#image

Optional Readonly imagePullPolicy

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

default

Always if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images

schema

io.k8s.api.core.v1.Container#imagePullPolicy

Optional Readonly lifecycle

lifecycle: Lifecycle

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

schema

io.k8s.api.core.v1.Container#lifecycle

Optional Readonly livenessProbe

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

schema

io.k8s.api.core.v1.Container#livenessProbe

Readonly name

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.

schema

io.k8s.api.core.v1.Container#name

Optional Readonly ports

ports: ContainerPort[]

List of ports to expose from the container. Exposing a port here gives the system additional information about the network connections a container uses, but is primarily informational. 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. Cannot be updated.

schema

io.k8s.api.core.v1.Container#ports

Optional Readonly readinessProbe

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

schema

io.k8s.api.core.v1.Container#readinessProbe

Optional Readonly resources

Compute Resources required by this container. Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

schema

io.k8s.api.core.v1.Container#resources

Optional Readonly securityContext

securityContext: SecurityContext
schema

io.k8s.api.core.v1.Container#securityContext

Optional Readonly startupProbe

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

schema

io.k8s.api.core.v1.Container#startupProbe

Optional Readonly stdin

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.

default

false.

schema

io.k8s.api.core.v1.Container#stdin

Optional Readonly stdinOnce

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

default

false

schema

io.k8s.api.core.v1.Container#stdinOnce

Optional Readonly terminationMessagePath

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.

default

dev/termination-log. Cannot be updated.

schema

io.k8s.api.core.v1.Container#terminationMessagePath

Optional Readonly terminationMessagePolicy

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.

default

File. Cannot be updated.

schema

io.k8s.api.core.v1.Container#terminationMessagePolicy

Optional Readonly tty

tty: boolean

Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false.

default

false.

schema

io.k8s.api.core.v1.Container#tty

Optional Readonly volumeDevices

volumeDevices: VolumeDevice[]

volumeDevices is the list of block devices to be used by the container.

schema

io.k8s.api.core.v1.Container#volumeDevices

Optional Readonly volumeMounts

volumeMounts: VolumeMount[]

Pod volumes to mount into the container's filesystem. Cannot be updated.

schema

io.k8s.api.core.v1.Container#volumeMounts

Optional Readonly workingDir

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.

schema

io.k8s.api.core.v1.Container#workingDir
