Introduction

Pauses one or more container for a certain time.

Details

The container is frozen for the whole duration and resumed afterwards.

If the container stops being paused before the duration is over, the attack completes early (it doesn't fail) and shows a warning summary in the experiment run. This happens, for example, when:

• a liveness probe fails and Kubernetes kills the frozen container
• the pod is deleted, evicted or rolled out, or the container is stopped, killed or restarted by an orchestrator or by hand
• the container runtime or the node is restarted
• the container is unpaused by someone else

Because the step ends early, the following steps of the lane start earlier than planned.

Note: Only available for the docker and containerd container runtimes.

Use Cases

• Interrupting a container for a certain time to simulate a outage
