[root@vm ~]# docker ps

# 1、先停止容器
[root@vm ~]# docker stop  test
linux   在/var/lib/docker。docker info 查看家目录
windows 在资源管理（进入磁盘文件夹时，左下角有 linux的小企鹅 
-> \\wsl.localhost\docker-desktop-data\data\docker\containers



# 2、进入对应的容器id文件夹，
6abe86895c0c
6abe86895c0c0cc02a283a9ae8c0deb97cf4b193876d4577e1af8e80cf85913c


# 3、修改hostconfig.json
{
    ...
        "PortBindings": {
                "80/tcp": [
                        {
                                "HostIp": "",
                                "HostPort": "38080"
                        }
                ],
                "22/tcp": [
                        {
                                "HostIp": "",
                                "HostPort": "2222"
                        }
                ]
        }
}


# 4、修改config.v2.json
{
...
        "Config": {
...
                "ExposedPorts": {
                        "38080/tcp": {},
                        "22/tcp": {}
        }
    }
}

# 5、重启docker服务（一定要重启）
systemctr restart docker

# 6、启动容器服务
systemctl start test
