docker重新打包MySQL5.7镜像

1：先下载MySQL镜像

# docker pull  mysql:5.7

 

2：运行镜像生成容器

# docker run --name mysql -p 3306:3306 -e MYSQL\_ROOT\_PASSWORD=123456  -d mysql:5.7

 

3：查看生成最新的容器

# docker ps -l

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

64f075017f93        mysql:5.7                  "docker-entrypoint..."   17 minutes ago      Exited (1) 16 minutes ago                                 mysql

 

4：进入容器查看是否安装成功

# docker exec -it mysql  bash

 

root@64f075017f93:/# mysql -uroot -p123456

7：生成新的镜像

# docker commit 64f075017f93  mysql:5.7.22

 

8：查看镜像

# docker images

REPOSITORY                   TAG                 IMAGE ID            CREATED             SIZE

mysql                        5.7                     66bc0f66b7af        2 weeks ago         372MB

 

9：测试新的镜像是否生效

# docker run --name mysql_test  -p 3306:3306 -e MYSQL\_ROOT\_PASSWORD=123456  -d mysql:5.7.22

# docker exec -it mysql_test  bash   

查看/etc/mysql/my.cnf配置文件

 

宿主机登陆测试MySQL数据库
