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.

affinity

object

Affinity is a group of affinity scheduling rules.

automountServiceAccountToken

boolean

containers[]

object

A single application container that you want to run within a pod.

dnsConfig

object

PodDNSConfig defines the DNS parameters of a pod in addition to those generated from DNSPolicy.

dnsPolicy

string

Set DNS policy for the pod. Defaults to "ClusterFirst". Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'. DNS parameters given in DNSConfig will be merged with the policy selected with DNSPolicy. To have DNS options set along with hostNetwork, you have to specify DNS policy explicitly to 'ClusterFirstWithHostNet'.

Possible enum values: - "ClusterFirst" indicates that the pod should use cluster DNS first unless hostNetwork is true, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - "ClusterFirstWithHostNet" indicates that the pod should use cluster DNS first, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - "Default" indicates that the pod should use the default (as determined by kubelet) DNS settings. - "None" indicates that the pod should use empty DNS settings. DNS parameters such as nameservers and search paths should be defined via DNSConfig.

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.

ephemeralContainers

array

List of ephemeral containers run in this pod. Ephemeral containers may be run in an existing pod to perform user-initiated actions such as debugging. This list cannot be specified when creating a pod, and it cannot be modified by updating the pod spec. In order to add an ephemeral container to an existing pod, use the pod’s ephemeralcontainers subresource.

ephemeralContainers[]

object

An EphemeralContainer is a temporary container that you may add 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. The kubelet may evict a Pod if an ephemeral container causes the Pod to exceed its resource allocation.

To add an ephemeral container, use the ephemeralcontainers subresource of an existing Pod. Ephemeral containers may not be removed or restarted.

hostAliases

array

HostAliases is an optional list of hosts and IPs that will be injected into the pod’s hosts file if specified.

hostAliases[]

object

HostAlias holds the mapping between IP and hostnames that will be injected as an entry in the pod’s hosts file.

hostPID

boolean

Use the host’s pid namespace. Optional: Default to false.

hostUsers

boolean

Use the host’s user namespace. Optional: Default to true. If set to true or not present, the pod will be run in the host user namespace, useful for when the pod needs a feature only available to the host user namespace, such as loading a kernel module with CAP_SYS_MODULE. When set to false, a new userns is created for the pod. Setting false is useful for mitigating container breakout vulnerabilities even allowing users to run their containers as root without actually having root privileges on the host. This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature.

object

LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace.

initContainers

array

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/

initContainers[]

object

A single application container that you want to run within a pod.

overhead

object (Quantity)

Overhead represents the resource overhead associated with running a pod for a given RuntimeClass. This field will be autopopulated at admission time by the RuntimeClass admission controller. 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

The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.

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.

Possible enum values: - "Always" - "Never" - "OnFailure"

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

schedulerName

string

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

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.

shareProcessNamespace

boolean

Share a single process namespace between all of the containers in a pod. When this is set containers will be able to view and signal processes from other containers in the same pod, and the first process in each container will not be assigned PID 1. HostPID and ShareProcessNamespace cannot both be set. Optional: 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.

terminationGracePeriodSeconds

integer

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.

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

array

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.

restartPolicy

string

RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod’s restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed.

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.

Possible enum values: - "FallbackToLogsOnError" will read the most recent contents of the container logs for the container status message when the container exits with an error and the terminationMessagePath has no contents. - "File" is the default behavior and will set the container status message to the contents of the container’s terminationMessagePath when the container exits.

The command is simply exec’d, it is not run inside a shell, so traditional shell instructions ('|', etc) won’t work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy.

mountPath

string

Path within the container at which the volume should be mounted. Must not contain ':'.

mountPropagation

string

mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10. When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified (which defaults to None).

Possible enum values: - "Bidirectional" means that the volume in a container will receive new mounts from the host or other containers, and its own mounts will be propagated from the container to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rshared" in Linux terminology). - "HostToContainer" means that the volume in a container will receive new mounts from the host or other containers, but filesystems mounted inside the container won’t be propagated to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rslave" in Linux terminology). - "None" means that the volume in a container will not receive new mounts from the host or other containers, and filesystems mounted inside the container won’t be propagated to the host or other containers. Note that this mode corresponds to "private" in Linux terminology.

readOnly

boolean

Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false.

recursiveReadOnly

string

RecursiveReadOnly specifies whether read-only mounts should be handled recursively.

If ReadOnly is false, this field has no meaning and must be unspecified.

If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason.

If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None).

If this field is not specified, it is treated as an equivalent of Disabled.

subPath

string

Path within the volume from which the container’s volume should be mounted. Defaults to "" (volume’s root).

subPathExpr

string

Expanded path within the volume from which the container’s volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container’s environment. Defaults to "" (volume’s root). SubPathExpr and SubPath are mutually exclusive.

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

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

targetContainerName

string

If set, the name of the container from PodSpec that this ephemeral container targets. The ephemeral container will be run in the namespaces (IPC, PID, etc) of this container. If not set then the ephemeral container uses the namespaces configured in the Pod spec.

The container runtime must implement support for this feature. If the runtime does not support namespace targeting then the result of setting this field is undefined.

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.

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.

Possible enum values: - "FallbackToLogsOnError" will read the most recent contents of the container logs for the container status message when the container exits with an error and the terminationMessagePath has no contents. - "File" is the default behavior and will set the container status message to the contents of the container’s terminationMessagePath when the container exits.
