内容

停止服务

##停止容器服务
docker stop <container id>

##停止docker服务
systemctl stop docker

修改配置

1. 进入配置目录

cd /var/lib/docker/containers/4fd7*/

2. 修改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

3. 修改config.v2.json中的ExposedPorts

vi config.v2.json
"ExposedPorts":{"2222/tcp":{},"5000/tcp":{},"80/tcp":{},"8081/tcp":{},"8087/tcp":{}},

重启服务

## 启动docker服务
systemctl start docker

## 启动容器
docker start <container id>

验证

docker ps -a
