Docker Environment Skill

Use this skill for container health checks, logs, and safe restarts. Prefer the least destructive command that answers the question.

Common Commands

• Status

  • docker compose ps -a

• Logs

  • docker compose logs <service> --tail=200
  • docker compose logs -f <service> (stream)

• Restart (service only)

  • docker compose restart <service>

• Rebuild (non-destructive)

  • docker compose up --build -d

Destructive Operations (ask before running)

• Cleanup

  • docker system prune -f

• Full reset

  • docker compose down -v
  • docker compose up --build -d

Compose Files

• Default: docker-compose.yml
• Local dev override: docker-compose.local.yml
  • Use docker compose -f docker-compose.yml -f docker-compose.local.yml ... if needed

Guidance

• Prefer targeted restarts before rebuilding or resetting volumes.
• Always capture logs before teardown for root-cause analysis.
