前提

• 服务器安装好docker和docker-compose
• 有个基于MongoDB的node服务——https://github.com/Heyff12/nest-test
• 整个docker里面，公用一个MongoDB容器

核心事项

链接外部容器，需要保证当前容器和外部容器在同一个network内

创建一个network，便于其他容器使用

docker network create mongo_net

独立部署MongoDB

新建docker-compose.yml

version: '3'
services:
  mongo_db:
    image: mongo
    restart: always
    ports:
      - "27017:27017"
    volumes:
      - "~/data/mongodb/db:/data/db"
    container_name: mongo_db
    networks:
      - default
      - mongo_net
networks:
  mongo_net:
    external: true

构建容器

docker-compose up -d

部署node服务

在根目录新建Dockerfile

FROM node:12
RUN mkdir -p /home/Service
WORKDIR /home/Service  
COPY ./ /home/Service  
RUN  npm install --production
EXPOSE 3001
CMD ["node","./src/main.js"]

新建deploy/docker-compose.yml

version: '3'
services:
  web:
    image: heyff12/nest-test
    ports:
      - 3001:3001
    container_name: heyff12_nest_test
    networks:
      - default
      - mongo_net
    external_links:
      - mongo_db
networks:
  mongo_net:
    external: true

新建.github/workflows/ali.yml

备注

通过docker启动的后端服务，在链接MongoDB容器时，需要替换MongoDB的链接：

mongodb://mongo_db/nest

mongo_db是MongoDB的容器名称
