container-kill

Kills a specific container within a pod without deleting the pod. The container runtime restarts the container according to the pod's restartPolicy.

Target kind: Pod
Implementation: Daemon (ExecStressChaos with stressorType: container-kill)
Rollback: None (container runtime handles restart)

Parameters

Name	Type	Required	Default	Description
containerName	string	Yes	—	Name of the container to kill

Example

apiVersion: chaos.chaosplane.io/v1alpha1
kind: ChaosExperiment
metadata:
  name: container-kill-example
  namespace: default
spec:
  target:
    kind: Pod
    namespace: default
    labelSelector:
      matchLabels:
        app: my-app
  action:
    type: container-kill
    parameters:
      containerName: "app"
  duration: 10s
  rollback:
    enabled: false

Rollback behavior

No rollback. The container runtime restarts the container based on the pod's restartPolicy (Always, OnFailure, or Never).

Implementation notes

The operator resolves target pods, then for each pod contacts the daemon on the pod's node via gRPC. The daemon sends SIGKILL to the container process using the container runtime socket (containerd or CRI-O). The containerName parameter must match exactly the container name in the pod spec.

containerName is required and validated before execution.
