Instana should detect a crash looping as incident
Intent
Verify that Instana alerts you that pods are not ready to accept traffic for some time.
Motivation
Kubernetes features a readiness probe to determine whether your pod is ready to accept traffic. If it isn't becoming ready, Kubernetes tries to solve it by restarting the underlying container and hoping to achieve its readiness eventually. If this isn't working, Kubernetes will eventually back off to restart the container, and the Kubernetes resource remains non-functional.
Structure
First, check that Instana has no critical events for an application perspective. As soon as one of the containers is crash looping, caused by the Steadybit attack crash loop, Instana should detect this via a critical event to ensure your on-call team is taking action.
