#debug

A container that stops right after docker run, or loops in "Restarting", almost always has a main process that exits or crashes. The exit code tells you why.

Routine for red or stuck workflow runs: read the failing step, enable debug logs, reproduce locally, and match the error against the usual suspects.

A top-down routine for any "my container is not working" moment: status, logs, config, inside, network, resources. Work down the list and stop at the first thing that looks wrong.

A top-down routine for any "my pod is not working" moment: status, events, logs, inside, network, resources. Stop at the first thing that looks wrong.

The container starts, exits, and Kubernetes backs off before restarting it. The pod is a symptom the cause is almost always in the previous container log or the probe config.

Runs a command inside an already-running container — the way in when you need to poke around live.

Shows the full low-level JSON for a container, image, volume or network: IP address, mounts, env vars, exit code, health and more.

Prints a container's stdout/stderr — the first place to look when a container is crashing or misbehaving.
