Docker Debugging

Authentication

Docker commands run directly via the Docker CLI. No API keys are needed - the Docker socket must be accessible in the sandbox environment.

Available Scripts

All scripts are in .claude/skills/infrastructure-docker/scripts/

container_ps.py - List Containers

python .claude/skills/infrastructure-docker/scripts/container_ps.py [--all]

container_logs.py - Get Container Logs

python .claude/skills/infrastructure-docker/scripts/container_logs.py --container NAME_OR_ID [--tail 100]

container_inspect.py - Inspect Container

python .claude/skills/infrastructure-docker/scripts/container_inspect.py --container NAME_OR_ID

container_stats.py - Resource Usage Statistics

python .claude/skills/infrastructure-docker/scripts/container_stats.py [--container NAME_OR_ID]

image_list.py - List Docker Images

python .claude/skills/infrastructure-docker/scripts/image_list.py [--filter "reference=myapp*"]

compose_ps.py - List Compose Services

python .claude/skills/infrastructure-docker/scripts/compose_ps.py [--file docker-compose.yml] [--cwd /path]

compose_logs.py - Get Compose Service Logs

python .claude/skills/infrastructure-docker/scripts/compose_logs.py [--services "api,db"] [--tail 100]

Investigation Workflow

Container Debugging

1. List containers: container_ps.py --all
2. Check logs: container_logs.py --container <name> --tail 200
3. Check resources: container_stats.py --container <name>
4. Inspect config: container_inspect.py --container <name>

Docker Compose Debugging

1. Check services: compose_ps.py
2. Check logs: compose_logs.py --services "api,worker" --tail 100

Anti-Patterns to Avoid

1. Never run destructive commands without explicit user approval (docker rm, docker rmi, docker system prune)
2. Always use --tail for logs to avoid overwhelming output
3. Check container status first before trying to exec into it
