nicolaka/netshoot ? reverse-engineered prompt

I want a Docker container that's ready to help me troubleshoot network problems in Docker or Kubernetes environments. It should include lots of popular network tools—like ping, traceroute, dig, tcpdump, curl, iproute2 and so on—so I can diagnose things like DNS issues, latency, firewalls, or routing problems. I want to be able to run this container interactively, or use it as a sidecar in a Kubernetes pod. It should also let me connect to the network namespace of another running container or pod so I can debug from inside their networking environment. Please make sure it works smoothly with Docker and Kubernetes, and loads up with a welcome prompt in the shell. Look up the latest tools and best practices online if you need extra info.
