[root@localhost ~]# 

2.测试一下mysql

[root@localhost ~]# docker run --name test.mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql
73ade7686685bf27fc70c713b27ec27a7d08ad7654134c6a5fc91672de2901cd
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
73ade7686685        mysql               "docker-entrypoint.s…"   4 seconds ago       Up 3 seconds        3306/tcp, 33060/tcp   test.mysql
[root@localhost ~]# docker exec -it test.mysql 
> mysql -uroot -p123456

3.挂载数据卷

#创建数据卷
[root@localhost ~]# docker volume create --name test.db
test.db
#查看数据卷信息
[root@localhost ~]# docker volume inspect test.db
[
    {
        "CreatedAt": "2019-04-26T18:14:25+08:00",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/test.db/_data",
        "Name": "test.db",
        "Options": {},
        "Scope": "local"
    }
]
#挂载数据卷启动MySql实例,需要把之前mysql容器删了
[root@localhost ~]# docker run --name test.mysql -v test.db:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql

4.安装Git并Clone示例项目

#安装Git
[root@localhost ~]# yum install git
#查看Git版本
[root@localhost ~]# git --version
git version 1.8.3.1
[root@localhost ~]# cd Documents
#拉取示例项目
[root@localhost Documents]# git clone https://github.com/yanshengjie/Docker.NetCore.MySql.git

#创建容器，将容器命名为docker.netcore.mysql，并使用--link参数与之前创建的test.mysql容器建立连接
[root@localhost Docker.NetCore.MySql]# docker run --name docker.netcore.mysql --link test.mysql:db -d -p 5000:5000 docker.netcore.mysql
d6f1174a3c18c9ceb49bcdb3ba68f9089dbf18a2532ffac824600eaaa2807476
#测试是否成功
[root@localhost Docker.NetCore.MySql]# curl http://localhost:5000/api/products
[{"productId":1,"name":"iphone 6","price":5000,"stockQty":10},{"productId":2,"name":"iphone 7","price":6000,"stockQty":10},{"productId":3,"name":"iphone 7 plus","price":7000,"stockQty":10},{"productId":4,"name":"iphone x","price":8000,"stockQty":10}]
[root@localhost Docker.NetCore.MySql]# 

5.使用docker-compose多容器部署示例项目

上述的示例代码目录里面已经存在docker-compose.yml和proxy.conf，可以使用cat指令查看下。

#我改了一些容器名称，所以跟刚下下来的示例代码不太一样。
[root@localhost Docker.NetCore.MySql]# cat docker-compose.yml
version: '2'
services:
  db:
    container_name: test.db
    image: mysql
    environment:
      MYSQL_ROOT_PASSWORD: 123456
    volumes:
      - ./mysql:/var/lib/mysql

  web:
    container_name: docker.web
    build: .
    depends_on:
      - db
    links:
      - db
  
  reverse-proxy:
    container_name: docker.proxy
    image: nginx
    depends_on:
      - web
    ports:
      - "9090:8080"
    volumes:
      - ./proxy.conf:/etc/nginx/conf.d/default.conf 
[root@localhost Docker.NetCore.MySql]# cat proxy.conf 
server {
    listen 8080;

    location / {
      proxy_pass http://web:5000;
    }
}

两个配置文件已存在，所以我们可以直接Compose，在此之前先清空一些之前测试的容器以免冲突。

#停止所有容器
[root@localhost Docker.NetCore.MySql]# docker stop $(docker ps -qa)
d6f1174a3c18
49eac84b374a
#删除所有容器
[root@localhost Docker.NetCore.MySql]# docker rm $(docker ps -qa)
d6f1174a3c18
49eac84b374a
#Compose
[root@localhost Docker.NetCore.MySql]# docker-compose up -d
Creating test.db ... done
Creating docker.web ... done
Creating docker.proxy ... done
#查看创建的容器
[root@localhost Docker.NetCore.MySql]# docker ps
CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                            NAMES
b719e4ce90ba        nginx                    "nginx -g 'daemon of…"   18 seconds ago      Up 15 seconds       80/tcp, 0.0.0.0:9090->8080/tcp   docker.proxy
7e4fc2220d86        dockernetcoremysql_web   "dotnet run"             23 seconds ago      Up 18 seconds       5000/tcp                         docker.web
5dbe9b8cefc0        mysql                    "docker-entrypoint.s…"   23 seconds ago      Up 22 seconds       3306/tcp, 33060/tcp              test.db
[root@localhost Docker.NetCore.MySql]# curl http://localhost:9090/api/products
[{"productId":1,"name":"iphone 6","price":5000.0000000000000000000000000,"stockQty":10},{"productId":2,"name":"iphone 7","price":6000.0000000000000000000000000,"stockQty":10},{"productId":3,"name":"iphone 7 plus","price":7000.0000000000000000000000000,"stockQty":10},{"productId":4,"name":"iphone x","price":8000.000000000000000000000000,"stockQty":10}]
[root@localhost Docker.NetCore.MySql]# 

最后我们可以验证一下数据库是否存在

[root@localhost Docker.NetCore.MySql]# docker exec -it test.db mysql -uroot -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.
