我想将frontend 也是用volumes，将其映射到/app/frontend目录，在/app/frontend下install以及build，如何实现 docker-compose.yml文件： version: '3' services: frontend: build: context: ./frontend dockerfile: Dockerfile ports: - 8010:80 restart: always backend: build: context: ./backend dockerfile: Dockerfile volumes: - /app/backend:/app environment: - CELERY_BROKER_URL=redis://redis:6379/0 command: python manage.py runserver 0.0.0.0:8000 ports: - 8011:8000 restart: always celery-worker: build: context: ./backend dockerfile: Dockerfile volumes: - /app/backend:/app environment: - CELERY_BROKER_URL=redis://redis:6379/0 command: celery -A server worker -l info --pool=solo --concurrency=1 depends_on: - redis - backend restart: always celery-beat: build: context: ./backend dockerfile: Dockerfile volumes: - /app/backend:/app environment: - CELERY_BROKER_URL=redis://redis:6379/0 command: celery -A server beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler depends_on: - redis - backend restart: always redis: image: redis:latest ports: - 6379:6379 restart: always mysql: image: mysql:latest environment: - MYSQL_ROOT_PASSWORD=sacfxSql258147@ ports: - 8016:3306 volumes: - ./mysql:/var/lib/mysql restart: always frontend：dockerfile文件 FROM node:16.18.1 WORKDIR /app/frontend COPY package*.json ./ RUN npm install COPY . .
