docker 操作镜像的基本操作

以安装mysql为例

1.拉取镜像
  docker pull mysql

错误的启动

[root@localhost ~]# docker run --name mysql01 -d mysql
42f09819908bb72dd99ae19e792e0a5d03c48638421fa64cce5f8ba0f40f5846

mysql退出了
[root@localhost ~]# docker ps -a

//错误日志
[root@localhost ~]# docker logs 42f09819908b
error: database is uninitialized and password option is not specified 
  You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD；这个三个参数必须指定一个

正确的启动

[root@localhost ~]# docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql

做了端口映射

[root@localhost ~]# docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql

当关闭后想要再次启动 首先要知道你做了容器映射后的id  找到指定的id，就可以启动容器了

[root@localhost ~]# docker ps -a
/etc/sysconfig/docker: line 4: PTIONS: command not found
/etc/sysconfig/docker: line 5: /bin/bash:: No such file or directory

执行这一步操作后就可以连接navicate进行数据库操作了。
