kubectl ns-debug

Troubleshoot a pod with a bring-your-own debug image.

⚠️ If you have ephemeral containers enabled in your cluster, use kubectl debug instead!

❗ Running pods with hostPID and hostNetwork are generally discouraged and you need to understand the risks.

❗ Only use this plugin if you understand what it is doing:

• spawning a container with hostPID and hostNetwork on the kubelet node
• having root access to the entire kubelet node
• being able to run anything on the kubelet node

For detailed explanation see EXPLAINED.md
