kubectl debug

CautionEphemeral debug containers

kubectl debug -it <pod> --image=busybox --target=<c>

Injects a tool container into shell-less pods; 'node/<n>' even drops you onto the node itself.

Examples

kubectl debug -it web-abc --image=nicolaka/netshoot --target=appAttach netshoot for diagnosis

Syntax

kubectl debug -it <pod> --image=<img> [--target=c] / node/<node>

Before you run it

Injecting into prod pods needs judgment.
