Using a sidecar is also an option for debugging stuff involving shared storage, yes. The distroless project also ships aptly named "debug" containers that have BusyBox if you want a minimal shell for debugging something in the container filesystem itself. I've also made use of self-made "debug" containers with go-delve or the JVM in their respecting over-the-network debugging modes and a kubectl port forward, for anything written by me.
