docker

name	docker
description	Docker workflow helpers — list containers, build, run, logs, compose up/down, prune. Non-interactive only.

Docker Skill

Run Docker operations in non-interactive mode.

Usage

/docker ps                    # List running containers
/docker logs service-name     # Tail logs for a service
/docker build                 # Build the project image
/docker up                    # docker compose up -d
/docker down                  # docker compose down
/docker restart service       # Restart a specific service
/docker prune                 # docker system prune -f (no named volumes)
/docker shell service         # Open a shell in a running container

Instructions

Determine action from $ARGUMENTS:

Argument	Action
ps or (empty)	docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}" | cat
logs <service>	docker logs <service> --tail 50 | cat
build	Read context/build.md for build command
up	docker compose up -d 2>&1 | tail -20
down	docker compose down 2>&1
restart <service>	docker compose restart <service> 2>&1
prune	docker system prune -f 2>&1 (confirm first)
shell <service>	docker exec <container-id> /bin/sh (non-interactive: run a command)
images	docker images | cat
stats	docker stats --no-stream | cat

⚠️ Rules:

• NEVER use docker exec -it (interactive — hangs terminal)
• For shell: run a specific command instead: docker exec <id> /bin/sh -c "ls /app"
• For prune: warn about consequences before running
• For logs: always --tail N to limit output
• Read context/build.md for project-specific Docker compose file paths and service names
