基于基础镜像使用dockerfile构建容器，再使用docker-compose编排容器

每个服务中的docker-compose.yaml只用与单独测试

第一步

在最外层建立docker-compose.yaml,用于所有容器的编排

version: "3.7"
services:
  mysqlserver:
    image: mysql/mysql-server:5.7
    restart: always
    tty: true
    container_name: composemysql
    volumes:
      - type: bind
        source: ./docker-cmdb/mysql/init.sql
        target: /docker-entrypoint-initdb.d/init.sql
      # - type: bind
      #   source: ./docker-cmdb/mysql/confile/my.cnf
      #   target: /etc/my.cnf
    environment:
      MYSQL_ROOT_PASSWORD: QFedu123!
    expose:
      - "3306"
    networks:
      - jumpserver-test

  redisserver:
    image: redis:alpine
    restart: always 
    container_name: composeredis
    expose:
      - "6379" 
    networks: 
      - jumpserver-test

  rabbitmqserver: 
    build: ./docker-cmdb/rabbitmq
    # build ./rabbitemq
    restart: always
    container_name: composerabbitmq
    expose:
      - "8081"
    networks: 
      - jumpserver-test 
   
  nginxserver:
    build: ./docker-cmdb/nginx/
    #build: ./nginx
    restart: always
    container_name: composenginx
    ports: 
      - "13141:80"
    volumes:
      - type: bind
        source: ./docker-cmdb/nginx/confile/default.conf
        target: /etc/nginx/conf.d/default.conf
      - type: bind
        source: ./docker-cmdb/nginx/allstatics/allstatic
        target: /root/
    networks:
      - jumpserver-test
    depends_on:
      - cmdb

  cmdb:
    build: ./docker-cmdb/cmdb
    restart: always
    container_name: composecmdb
    tty: true
    command: 
      - /bin/bash
      - -c
      - |  
        python3 /opt/auto_cmdb/manage.py makemigrations 
        python3 /opt/auto_cmdb/manage.py migrate 
        uwsgi --ini /opt/auto_cmdb/conf/auto_cmdb.ini
    expose:
      - "80"
    networks:
      - jumpserver-test
    depends_on:
      - mysqlserver
      - redisserver
      - rabbitmqserver

networks:
  jumpserver-test:

mysqlserver

init.sql:用于初始化数据库并创建用户进行授权

create database cmdb CHARACTER SET utf8 COLLATE utf8_general_ci;
grant all on cmdb.* to cmdb@'%' identified by 'QFedu123!';

环境变量：
设置root用户的密码

rabbitmqserver

Dockerfile：

FROM rabbitmq:latest
COPY ./startmq.sh /
CMD sh /startmq.sh

startmq.sh:设置rabbitmq的用户，组，权限

#!/bin/bash
RABBITMQ_USER=rourou
RABBITMQ_PASSWORD=rourou
# Create Rabbitmq user
rabbitmq-server &
sleep 6
while true
do
    rabbitmqctl ping &>/dev/null
    if [ "$?" -eq 0 ];then
        rabbitmqctl ping
        rabbitmqctl add_user $RABBITMQ_USER $RABBITMQ_PASSWORD &&  rabbitmqctl add_vhost myvhost && rabbitmqctl set_permissions -p myvhost $RABBITMQ_USER  ".*" ".*" ".*"
        break
    fi
done
rabbitmqctl stop
sleep 10
rabbitmq-server

nginxserver

Dockerfile：使用高山的nginx镜像就必须使用该条CMD命令

FROM nginx:alpine3.10
CMD ["nginx","-g","daemon off;"]

default.conf：nginx的配置文件

upstream django {   
    server composecmdb:80;   
}

server {
    listen       80; 
    server_name  composenginx;
 
    location /static {
        alias /root/allstatic;
    }
    location / {
        uwsgi_pass django; 
        include uwsgi_params;  
    }
}

alalstatic：cmdb的静态文件，为了实现动静分离
python3 manage.py collectstatic ---> 将锁与静态文件都拷贝到settings锁指定的文件中
settings：STATIC_ROOT = os.path.join(BASE_DIR,"allstatic")
当然，前提是已经注释了STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'),]

cmdb

Dockerfile：

FROM centos7test:v1

centos7test:v1的Dockerfile:

FROM centos7-python3.7
ONBUILD COPY . /opt/ 
ONBUILD RUN pip3 install -r /opt/requirements.txt && pip3 install uwsgi  

pip3 freeze > requirements.txt 得到环境安装的所有的包

command:执行数据的迁移，并且使用uwsgi启动项目。与nginx的default.conf对应
