https://textbooks.cs.ksu.edu/extras/02-full-stack/07-database/index.html Now let’s add a database to our project. Postgres Container First, we can add an entry to our Docker Compose file to create a Postgres database, and also an entry for the volume to store the data: # docker-compose.yml services: # database project-db: # Use an existing image from DockerHub image: postgres:15 container_name: project-db # Automatically restart the container as needed restart: unless-stopped networks: - project-network volumes: # Persist database data in a Docker volume - project_db_data:/var/lib/postgresql/data:rw environment: # Configure environment using .env file POSTGRES_USER: POSTGRES_PASSWORD: POSTGRES_DB: healthcheck: # check if database is running and healthy test: ["CMD-SHELL", "pg_isready -d $${POSTGRES_DB} -U $${POSTGRES_USER}"] interval: 30s timeout: 5s retries: 5 start_period: 10s # server project-server: build: # location of Dockerfile context: ./server container_name: project-server # set the user ID to match our user user: "1000" depends_on: # requires database to start - project-db networks: - project-network # allow external connections (remove this in production) - default volumes: # mount code into container - ./server:/app/server # maintain existing node_modules in container - /app/server/node_modules # client project-client: build: # location of Dockerfile context: ./client container_name: project-client # set the user ID to match our user user: "1000" depends_on: # requires server to start - project-server networks: - project-network # allow external connections - default volumes: # mount code into container - ./client:/app/client # maintain existing node_modules in container - /app/client/node_modules volumes: project_db_data: networks: # internal Docker network for project project-network: name: project-network internal: true Refer to the Postgres Docker Image documentation for more details.
