Chapter 38. PodTemplate schema reference

metadata

MetadataTemplate

Metadata applied to the resource.

imagePullSecrets

LocalObjectReference array

List of references to secrets in the same namespace to use for pulling any of the images used by this Pod. When the STRIMZI_IMAGE_PULL_SECRETS environment variable in Cluster Operator and the imagePullSecrets option are specified, only the imagePullSecrets variable is used and the STRIMZI_IMAGE_PULL_SECRETS variable is ignored.

securityContext

PodSecurityContext

Configures pod-level security attributes and common container settings.

terminationGracePeriodSeconds

integer

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 to longer than the expected cleanup time for your process. Value must be a non-negative integer. A zero value indicates delete immediately. You might need to increase the grace period for very large Kafka clusters, so that the Kafka brokers have enough time to transfer their work to another broker before they are terminated. Defaults to 30 seconds.

affinity

Affinity

The pod’s affinity rules.

tolerations

Toleration array

The pod’s tolerations.

topologySpreadConstraints

TopologySpreadConstraint array

The pod’s topology spread constraints.

priorityClassName

string

The name of the priority class used to assign priority to the pods.

schedulerName

string

The name of the scheduler used to dispatch this Pod. If not specified, the default scheduler will be used.

hostAliases

HostAlias array

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

enableServiceLinks

boolean

Indicates whether information about services should be injected into Pod’s environment variables.

tmpDirSizeLimit

string

Defines the total amount of pod memory allocated for the temporary EmptyDir volume /tmp. Specify the allocation in memory units, for example, 100Mi for 100 mebibytes. Default value is 5Mi. The /tmp volume is backed by pod memory, not disk storage, so avoid setting a high value as it consumes pod memory resources.

volumes

AdditionalVolume array

Additional volumes that can be mounted to the pod.
