docker-compose之.netcore+mysql+Ocelot多容器部署

继上节.NetCoreApi容器与MySql容器互联继续讲解，主要增加了Ocelot网关。

项目结构

编写 docker-compose.yml 文件

version: '3'
services:
  db:
    image: mysql:5.5  
    command: mysqld --character-set-server=utf8 --collation-server=utf8_general_ci

    restart: always
    ports:
      - "3306:3306"
    environment:
      - MYSQL_PASSWORD=123456
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_USER=yak
    networks: 
      - dev
    volumes:  
      - "./db:/var/lib/mysql"
      - "./conf/my.cnf:/etc/my.cnf"
      - "./init:/docker-entrypoint-initdb.d/"

    driver: bridge

编写 ocelot.json 文件
