参考：docker mysql 官方文档
1.首先查看下仓库镜像
docker search mysql[root@k8s~]# docker search mysql

2.然后从hub.docker.com或者第三方有加速的docker网站查看mysql镜像版本
8.0.3, 8.0, 8 (8.0/Dockerfile)
5.7.20, 5.7, 5, latest (5.7/Dockerfile)
5.6.38, 5.6 (5.6/Dockerfile)
5.5.58, 5.5 (5.5/Dockerfile)3.我选择5.6.38版本下载
docker pull mysql:5.6.38[root@k8s~]# docker pull mysql:5.6.38

Status: Downloaded newer image for mysql:5.6.384.查看本地镜像 可以看到已经在本地仓库
docker images[root@k8s~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 5.6.38 15a5ee56ec55 6 weeks ago 299MB
5.开启mysql一个容器(就是我们平常所说的实例)
docker run --name mysql5.6.38 -e MYSQL_ROOT_PASSWORD=root -d -p 3306:3306 mysql:5.6.38-e MYSQL_ROOT_PASSWORD=root 初始化密码[root@k8s~]# docker run --name mysql5.6.38 -e MYSQL_ROOT_PASSWORD=root -d -p 3306:3306 mysql:5.6.38
1794aed7cfe17c7a8df7c1403a25feaecced3ccbef3844c9240bb0c8e27c2b85
[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1794aed7cfe1 mysql:5.6.38 "docker-entrypoint.s…" 7 seconds ago Up 6 seconds 0.0.0.0:3306->3306/tcp mysql5.6.386.mysql远程连接
navicat远程连接mysql容器 –> 外网地址:3306
如果是阿里云esc服务器,安全组3306端口要开放
7.如果是在同一个docker下的容器要连接mysql
7.1别名访问
比如tomcat连接mysql,那tomcat的启动参数里要加–link连接
docker run --name tomcat8.5.24 --link mysql5.6.38:别名 -d tomcat:8.5.24在tomcat容器里的mysql连接地址就写为:别名
比如：jdbc:mysql://192.168.123.123:3306
就写为:jdbc:mysql://别名:33067.2内网ip访问(相当于局域网访问)
获取mysql容器内网ip地址
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mysql5.6.38[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
432bd371973f tomcat:8.5.24 "catalina.sh run" 12 minutes ago Up 12 minutes 0.0.0.0:8080->8080/tcp tomcat8.5.24
1794aed7cfe1 mysql:5.6.38 "docker-entrypoint.s…" 3 hours ago Up About an hour 0.0.0.0:3306->3306/tcp mysql5.6.38
[root@k8s~]# docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mysql5.6.38
172.17.0.2获取tomcat容器内网ip地址也可以使用管道过滤
docker inspect 1794aed7cfe1 | grep IPAddress[docker@k8s~]# docker inspect 1794aed7cfe1|grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.2",
"IPAddress": "172.17.0.2"在tomcat容器里的mysql连接地址就写为:内网ip
比如：jdbc:mysql://192.168.123.123:3306
jdbc:mysql://172.17.0.2:33068.进入mysql容器
docker exec -it 容器id或者容器名字 /bin/bash[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1794aed7cfe1 mysql:5.6.38 "docker-entrypoint.s…" 29 minutes ago Up 29 minutes 0.0.0.0:3306->3306/tcp mysql5.6.38
[root@k8s~]# docker exec -it 1794aed7cfe1 /bin/bash
