Datadog Alerts when a Kubernetes Pod Is in Crash Loop
Go back to listVerify that a Datadog monitor alerts you when pods are not ready to accept traffic for a certain 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 the Datadog monitor responsible for tracking non-ready containers is in an 'okay' state. As soon as one of the containers is crash looping, caused by the crash loop attack, the Datadog monitor should alert and escalate it to your on-call team.
