在Docker容器已经创建后，需要添加新的端口映射，即对已经存在的Docker容器添加新的端口映射，可以通过以下步骤来添加，即通过修改配置文件的方法。

1、Windows 10 下 Dockers容器的配置文件修改步骤：

1、先找到要修改的容器hash值：

docker inspect 容器名称

2、然后退出docker Desktop服务（因为在线状态配置文件修改保存不了）

3、资源管理器中打开最新安装的Docker的配置文件的路径：

\\wsl$\docker-desktop-data\data\docker\containers\[容器hash值]
win11一般为：
\\wsl.localhost\docker-desktop-data\data\docker\containers\[容器hash值]

4、修改配置文件

打开后修改其中的 config.v2.json 和 hostconfig.json

config.v2.json有两处需要添加，只修改一处，是不行的：
位置1：
"ExposedPorts":{"20/tcp":{},"21/tcp":{},"22/tcp":{},"3306/tcp":{},"443/tcp":{},"6379/tcp":{},"80/tcp":{},"8081/tcp":{},"8082/tcp":{},"8083/tcp":{},"8084/tcp":{},"888/tcp":{},"8888/tcp":{},"9501/tcp":{},"9502/tcp":{}}
位置2：
"Ports":{"20/tcp":[{"HostIp":"0.0.0.0","HostPort":"1020"}],"21/tcp":[{"HostIp":"0.0.0.0","HostPort":"1021"}],"22/tcp":[{"HostIp":"0.0.0.0","HostPort":"1022"}],"3306/tcp":[{"HostIp":"0.0.0.0","HostPort":"13306"}],"443/tcp":[{"HostIp":"0.0.0.0","HostPort":"10443"}],"6379/tcp":[{"HostIp":"0.0.0.0","HostPort":"16379"}],"80/tcp":null,"8081/tcp":[{"HostIp":"0.0.0.0","HostPort":"8081"}],"8082/tcp":[{"HostIp":"0.0.0.0","HostPort":"8082"}],"8083/tcp":[{"HostIp":"0.0.0.0","HostPort":"8083"}],"8084/tcp":[{"HostIp":"0.0.0.0","HostPort":"8084"}],"888/tcp":[{"HostIp":"0.0.0.0","HostPort":"888"}],"8888/tcp":[{"HostIp":"0.0.0.0","HostPort":"8888"}],"9501/tcp":[{"HostIp":"0.0.0.0","HostPort":"9501"}],"9502/tcp":[{"HostIp":"0.0.0.0","HostPort":"9502"}]}

hostconfig.json 有一处：
"PortBindings":{"20/tcp":[{"HostIp":"","HostPort":"1020"}],"21/tcp":[{"HostIp":"","HostPort":"1021"}],"22/tcp":[{"HostIp":"","HostPort":"1022"}],"3306/tcp":[{"HostIp":"","HostPort":"13306"}],"443/tcp":[{"HostIp":"","HostPort":"10443"}],"6379/tcp":[{"HostIp":"","HostPort":"16379"}],"8081/tcp":[{"HostIp":"","HostPort":"8081"}],"8082/tcp":[{"HostIp":"","HostPort":"8082"}],"8083/tcp":[{"HostIp":"","HostPort":"8083"}],"8084/tcp":[{"HostIp":"","HostPort":"8084"}],"888/tcp":[{"HostIp":"","HostPort":"888"}],"8888/tcp":[{"HostIp":"","HostPort":"8888"}],"9501/tcp":[{"HostIp":"","HostPort":"9501"}],"9502/tcp":[{"HostIp":"","HostPort":"9502"}]}
