Docker Compose ist mehr als “docker compose up”. Hier sind 10 fortgeschrittene Techniken.

1. Profiles¶

services: debug: profiles: [debug]

docker compose –profile debug up¶

2. YAML Anchors¶

x-common: &common restart: unless-stopped services: app: <<: *common

3. Health Checks + depends_on¶

services: db: healthcheck: test: [“CMD-SHELL”, “pg_isready”] app: depends_on: db: { condition: service_healthy }

4. Env-Dateien¶

env_file: [.env, .env.local]

5. Benannte Volumes¶

volumes: pgdata: services: db: volumes: [“pgdata:/var/lib/postgresql/data”]

6. Interne Netzwerke¶

networks: backend: { internal: true }

7. Ressourcenlimits¶

deploy: resources: limits: { memory: 512M, cpus: “1.0” }

8. Multi-File Compose¶

docker compose -f compose.yml -f compose.prod.yml up

9. Init Container¶

migrate: command: [“python”, “manage.py”, “migrate”] app: depends_on: migrate: { condition: service_completed_successfully }

10. Watch-Modus¶

develop: watch: - action: sync path: ./src target: /app/src

Tipp¶

Profiles für Dev/Prod, Health Checks für die Startreihenfolge, YAML Anchors gegen Duplizierung.
