PodSpec.initContainers.lifecycle.preStop

LifecycleHandler defines a specific action that should be taken in a lifecycle hook. One and only one of the fields, except TCPSocket must be specified.

PodSpec.initContainers.lifecycle.preStop fields and descriptions
Field / Type	Description
exec `ExecAction`	Exec specifies the action to take.
httpGet `HTTPGetAction`	HTTPGet specifies the http request to perform.
sleep `SleepAction`	Sleep represents the duration that the container should sleep before being terminated.
tcpSocket `TCPSocketAction`	Deprecated. TCPSocket is NOT supported as a LifecycleHandler and kept for the backward compatibility. There are no validation of this field and lifecycle hooks will fail in runtime when tcp handler is specified.
