Introduction

The rollout restart attack helps simulate the rollout of a Kubernetes deployment. More specifically, the attack issues a kubectl rollout restart command. This command adds an annotation with the current time to the Kubernetes deployment, which then forces the ReplicaSet to reconcile the state, i.e., update all pods.

Use Cases

• Check that a service remains available during rollouts, e.g., with the help of rolling rollouts.
• Verify how upstream services behave during a rollout of downstream services.
• Check that load balancer configurations update after updates.
• See whether persistent connections to a restarting service get re-established.

Rollback

No rollback possible.
