docker-troubleshooting

Guides systematic diagnosis of failing Docker containers and Compose services — crash loops, unexpected exit codes, OOM kills, port conflicts, inter-container network/DNS problems, health-check flapping, and image build failures — using read-only inspection before any state-changing action. Trigger when a user reports a container that won't start, keeps restarting, exits immediately, is unreachable, or when docker/docker compose commands error out. Not for authoring new Dockerfiles from scratch or for orchestration platforms like Kubernetes.
