How to exec into container?

[Crelanss]

Is your documentation request related to a feature? If so, which one?

I just cant debug installation because when I try to exec any command, like
kubectl exec -n mimir mimir-alertmanager-0 -- echo hello I receive error
error: Internal error occurred: Internal error occurred: error executing command in container: failed to exec in container: failed to start exec "f83e8b9fb8a93967e92156dacf47bb705db27755e6fd7c697042b31ded03d61f": OCI runtime exec failed: exec failed: unable to start container process: exec: "echo": executable file not found in $PATH: unknown

What is the solution that you would like or the expected outcome?

Written documentation on how to work with your containers

What did you think would happen?

What was your environment?

kubernetes 1.31, grafana/mimir:2.14.0

Any additional context to share?

No response

The reason it can't find echo is because Mimir is using a distroless image as a base image.

There is existing documentation for how to debug distroless container images here: https://grafana.com/docs/mimir/latest/manage/mimir-runbooks/#debugging-distroless-container-images-in-kubernetes
