修改 Docker 运行中 Container 的映射端口。

（1）停止服务

停止容器服务

docker stop <container id>

停止 docker 服务 (Linux)

systemctl stop docker

（2）修改配置

查看 container 的 id hash 值

docker inspect <container_name>

C:\Users\xxj87>docker inspect b61792d860f2 [ { "Id": "b61792d860f24c7ba47f4e270e211736a1a88546375e97380884c577d31dab66", "Created": "2022-07-01T07:46:03.516440885Z", "Path": "/bin/sh",

配置目录

[nux]: cd /var/lib/docker/containers/4fd7/

修改文件 hostconfig.json 中的 PortBindings

vim hostconfig.json

"PortBindings":{"2222/tcp":[{"HostIp":"","HostPort":"2222"}],"5000/tcp":[{"HostIp":"","HostPort":"5000"}],"80/tcp":[{"HostIp":"","HostPort":"40001"}],"8070/tcp":[{"HostIp":"","HostPort":"8070"}],"8081/tcp":[{"HostIp":"","HostPort":"8081"}]},

"80/tcp":[{"HostIp":"","HostPort":"40001"}] 80 容器内部端口 40001 外部映射端口

修改 config.v2.json 中的 ExposedPorts

vi config.v2.json "ExposedPorts":{"2222/tcp":{},"5000/tcp":{},"80/tcp":{},"8081/tcp":{},"8070/tcp":{}},

重启服务

systemctl start docker

启动容器

docker start <container id>

验证修改

docker ps -a
