Docker容器添加新的端口映射

转载自：https://blog.51cto.com/u_15228753/2818167

step 1: 查看容器哈希编码

1
docker inspect centos-desktop-vnc | grep Id
1
"Id": "22132e73736a5700dd5b4215a122310220fc3192b19754917caa1b83ecb89dd3",

step 2: 停止目标容器

1
docker stop centos-desktop-vnc

step 3: 修改配置文件

1
sudo vim /var/lib/docker/containers/<容器Id>/hostconfig.json

加入映射配置

1
{    "PortBindings":{            "22/tcp":[{"HostIp":"","HostPort":"10112"}],            "5901/tcp":[{"HostIp":"","HostPort":"10113"}],            "3306/tcp": [{"HostIp":"","HostPort":"10114"}],            "5672/tcp": [{"HostIp":"","HostPort":"10115"}],            "6379/tcp": [{"HostIp":"","HostPort":"10116"}],            "8080/tcp": [{"HostIp":"","HostPort":"10117"}],            "80/tcp": [{"HostIp":"","HostPort":"10118"}],    },}

修改下一个配置：

1
sudo vim /var/lib/docker/containers/<容器Id>/config.v2.json

补齐配置：

1
{    "ExposedPorts":{        "22/tcp":{},        "5901/tcp":{},        "3306/tcp":{},        "5672/tcp":{},        "6379/tcp":{},        "8080/tcp":{},        "80/tcp":{}    }}

step 4: 重启docker服务

1
service docker restart

step 5: 重启容器

1
docker start centos-desktop-vnc

访问响应的端口，查看是否映射成功。
