Debugging with Ephemeral Containers

Ephemeral containers are a beta feature landing with Kubernetes v1.23.These special containers allow for easier debugging of pods/containers, especially if you use “distroless images”, which only contain your application and runtime dependencies. In those cases, you usually wouldn’t even be able to get a shell via “kubectl exec”.This presentation will show how to use “kubectl debug”, which allows Kubernetes users to spin up these special containers to inspect the state of a failing container. We’ll also show how to enable process namespace sharing to gain deeper visibility into the failing pod.
