Docker-compose 启动单个容器

Question

I'm using docker-compose and I'm trying to run an express app and postgres db in docker containers. My problem is that it only starts postgres image, but express app is not running.

What am I doing wrong?

Answer 1

looking at your docker-compose file and Dockerfile , i assume that your intention is that the web service in the compose will actually run the image produced by the Dockerfile.

if that is the case, you need to modify the compose file and tell it to build an image based on the Dockerfile.

it should look something like

version: "3.7"
services: 
  web: 
    image: node
    build: .  # <--- this is the missing line
    depends_on: 
      - db
    ports: 
      - '3001:3001'
  db: 
    image: postgres
    environment: 
      POSTGRES_PASSWORD: 123123123
      POSTGRES_USER: yakym
      POSTGRES_DB: jwt
    volumes: 
      - ./pgdata:/var/lib/postgresql/data
    ports: 
      - '5433:5433'
