How hard is it to debug containers in Kubernetes?

F.A.Q

How do I fix a stable-slim container that doesn't support debugging tools?

The most obvious solution is to put the debugging tools back when you need them. For instance, a container built from debian:stable-slim lacks even the basic stuff like ps: sleep 9999 # Nice, the shell is there! root@6aa917a50213:/ $# # But many tools are missing. You can "fix" it by installing the procps package right into the running container:

What is containerd & how does it work?

containerd is a high-level container runtime, aka container manager. To put it simply, it's a daemon that manages the complete container lifecycle on a single host: creates, starts, stops containers, pulls and stores images, configures mounts, networking, etc. containerd is designed to be easily embeddable into larger systems.

How hard is it to debug containers in Kubernetes?

Debugging even simple containerized applications is challenging. Debugging applications that run in distroless containers is hard. And debugging distroless containers running in a Kubernetes cluster is close to impossible. Unless you know a trick a two.

How does debug shell work?

Debug Shell automatically asks you to install commands the first time you try to run them: Since it's is an "overlay" on top of the container, it doesn't modify the actual container or image at all, and works on read-only containers. All the extra tools work exactly as if they were running directly in your container.

Is a slim container better than a cdebug tool?

UPD: Check out iximiuz/cdebug - a container debugging tool that automates some of the techniques from this post. Slim containers are faster (less stuff to move around) and more secure (fewer places for vulnerabilities to sneak in).
