Docker：如何使用Redis Docker镜像

首先，从库中取下Redis。

> $ docker pull redis

接着，启动redis server，启动时设置端口映射，使其可以被外部访问。

> $ docker run --name test-redis -p 6379:6379 -d redis  
> 775e30ad251042fab3b397ff68a603796b50ccf3fe592f0256c78ae38919c218

然后，启动redis client，将IP设置为127.0.0.1，网络设置为host，此时容器继承了宿主机的IP地址。命令执行完成后，就可以执行redis命令了。

> $ docker run --name test-redis-cli -it --network host --rm redis redis-cli  -h 127.0.0.1  
> 127.0.0.1:6379>

或者，先查看test-redis在容器上的IP。

> $ docker network inspect bridge  
> \[  
>     \{  
>         "Name": "bridge",  
>         "Id": "fef17235611317db053a20bd182fc7c690b2751a048c2b0f989b509ba94aa4bd",

> \]

再将网络设置为bridge（bridge为默认值，可以不设置），IP设置为172.17.0.2。

> $ docker run --name test-redis-cli --network bridge -it --rm redis redis-cli -h 172.17.0.2  
> 172.17.0.2:6379>

最后，可以查看到此时有两个客户实例在执行。

> $ docker ps -a  
> CONTAINER ID   IMAGE COMMAND                    CREATED         STATUS            PORTS                             NAMES  
> f6ba17249d4a      redis    "docker-entrypoint.s…"   5 seconds ago   Up 5 seconds                                            test-redis-cli  
> 775e30ad2510     redis    "docker-entrypoint.s…"   2 minutes ago    Up 2 minutes     0.0.0.0:6379->6379/tcp   test-redis
