Defaults to all module properties rendered as either Pcf or the format specified on the command line.
link

dnsPolicy: ("ClusterFirstWithHostNet"|"ClusterFirst"|"Default"|"None")?Source

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'.
link

nodeName: String?Source

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.
link

terminationGracePeriodSeconds: Int?Source

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.
link

link

priorityClassName: String?Source

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.

link

runtimeClassName: String?Source

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
link

tolerations: Listing<Toleration>?Source

If specified, the pod's tolerations.

link

setHostnameAsFQDN: Boolean?Source

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.
link

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
link

hostIPC: Boolean?Source

Use the host's ipc namespace.

Optional: Default to false.

List of volumes that can be mounted by containers belonging to the pod.

More info: https://kubernetes.io/docs/concepts/storage/volumes
link

ephemeralContainers: Listing<EphemeralContainer>?Source

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.
link

serviceAccount: String?Source

Deprecated.

DeprecatedServiceAccount is a deprecated alias for ServiceAccountName.
Deprecated: Use serviceAccountName instead.
link

priority: Int32?Source

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.
link

restartPolicy: ("Always"|"OnFailure"|"Never")?Source

Restart policy for all containers within the pod.

One of Always, OnFailure, Never. In some contexts, only a subset of those values may be permitted. Default to Always. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#restart-policy
link

shareProcessNamespace: Boolean?Source

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.
link

hostUsers: Boolean?Source

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.
link

resourceClaims: Listing<PodResourceClaim>?Source

ResourceClaims defines which ResourceClaims must be allocated and reserved before the Pod is allowed to start.

The resources will be made available to those containers which consume them by name.

This is an alpha field and requires enabling the DynamicResourceAllocation feature gate.

This field is immutable.
link

subdomain: String?Source

If specified, the fully qualified Pod hostname will be "...svc.".

If not specified, the pod will not have a domainname at all.
link

containers: Listing<Container>Source

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.
link

initContainers: Listing<Container>?Source

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/
link

affinity: Affinity?Source

If specified, the pod's scheduling constraints
link

hostPID: Boolean?Source

Use the host's pid namespace.

Optional: Default to false.
