1.安装docker-compose

 pip install docker-compose

2.编写docker-compose.yml

包含了四个服务

• db
• server
• web
• mq

version: '3'
services:
  db:
    image: docker.io/mysql:5.7
    container_name: mysql
    privileged: true
    env_file:
      - "./FasterRunner/.env"
    environment:
      # 设置默认数据库和root默认密码,如果宿主机中/var/lib/mysql已经存在,这两个设置都不会生效
      - MYSQL_DATABASE="${FASTER_DB_NAME}"
      - MYSQL_USER="${FASTER_DB_USERNAME}"
      - MYSQL_ROOT_PASSWORD="${FASTER_DB_ROOT_PASSWORD}"
    volumes:
      - "/var/lib/mysql:/var/lib/mysql" # 挂载宿主机的mysql数据到docker中
      - "./FasterRunner/docker_mysql.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf"  # 把宿主机文件挂在到容器的mysql配置文件
    # 端口映射,格式 宿主机端口:容器端口
    ports:
      - "3306:3306"
    restart: always
    # 容器开机启动命令
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    networks:
      - fasterrunner


  server:
    image: fasterrunner:latest
    container_name: fasterrunner
    privileged: true
    volumes:
      - ./FasterRunner:/opt/workspace/FasterRunner
      - ./FasterRunner/nginx.conf:/etc/nginx/sites-enabled/nginx.conf
    ports:
      - "8000:8000"
    networks:
      - fasterrunner

  web:
    image: fasterweb:latest
    container_name: fastweb
    privileged: true
    volumes:
      - ./FasterWeb/dist:/usr/share/nginx/html
      - ./FasterWeb/default.conf:/etc/nginx/conf.d/default.conf
    ports:
      - "8080:8080"
    networks:
      - fasterrunner

  mq:
    image: rabbitmq:management-alpine
    container_name: rabbitmq
    env_file:
      - "./FasterRunner/.env"
    environment:
      - RABBITMQ_DEFAULT_USER=${FASTER_MQ_USER}
      - RABBITMQ_DEFAULT_PASS=${FASTER_MQ_PASSWORD}
    restart: always
    ports:
      - "15672:15672"
      - "5672:5672"
    networks:
      - fasterrunner

networks:  # 指定了内网，可以在配置文件中直接使用容器名字，但是需要先在宿主机创建网络
  fasterrunner:
    external: true

3.编写环境变量.env文件(在FasterRunner项目的根据路径)

# .env文件

# MQ
FASTER_MQ_USER=my_mq_username  # rabbitmq容器创建的默认用户名
FASTER_MQ_PASSWORD=my_mq_password  # rabbitmq容器创建的默认密码

# MySQL
FASTER_HOST=10.0.3.67 # 服务器本机ip地址
FASTER_DB_NAME=my_db # mysql容器创建的默认数据库名
FASTER_DB_USERNAME=my_db_user # mysql容器创建的默认用户名
FASTER_DB_PASSWORD=my_db_password # mysql容器创建的默认用户密码
FASTER_DB_ROOT_PASSWORD=my_db_root_password # mysql容器创建的默认root密码

4.构建镜像

在docker-compose中使用了4个镜像,下面两个是属于自定义的,所以需要预先构建.剩下的两个会自动在docker官方拉取
image: fasterrunner:latest
image: fasterweb:latest

# 进入FasterRunner项目根目录
(fasterenv) [faster@faster_3_57 FasterRunner]$ cd /home/faster/FasterRunner
(fasterenv) [faster@faster_3_57 FasterRunner]$ pwd
/home/faster/FasterRunner

# 构建fasterrunner:latest镜像
 docker build -t fasterrunner:latest .

# 进入FasterWeb项目根目录
(fasterenv) [faster@faster_3_57 FasterRunner]$ cd /home/faster/FasterWeb/
(fasterenv) [faster@faster_3_57 FasterWeb]$ pwd
/home/faster/FasterWeb

# 构建 fasterweb:latest镜像()
docker build -t fasterweb:latest .

5.文件结构如下

(fasterenv) [faster@faster_3_57 ~]$ ls -l
-rw-rw-r--  1 faster faster 2010 Dec 31 15:03 docker-compose.yml
drwxrwxr-x  9 faster faster 4096 Jan  6 09:43 FasterRunner
drwxrwxr-x  8 faster faster 4096 Jan  6 15:18 FasterWeb

6.启动所有服务

# 在docker-compose.yml所在的目录
docker-compose up # 首次启动会提示需要重新network

# 后台运行模式
docker-compose up -d

7.docker-compose常用命令

# 停止并清理容器
docker-compose down

# 查看所有容器端口映射
docker-compose ps

# 查看所有容器的进程
docker-compose top

# 查看所有容器的配置(环境变量)
docker-compose config

# 查看容器的日志
docker-compose logs -f web

# 进入容器
docker exec -it fasterrunner /bin/sh
