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

docker inspect centos-desktop-vnc | grep Id

"Id": "22132e73736a5700dd5b4215a122310220fc3192b19754917caa1b83ecb89dd3",

step 2: 停止目标容器

docker stop centos-desktop-vnc

step 3: 修改配置文件

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

加入映射配置

{
    "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：

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

补齐配置：

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

step 4: 重启docker服务

service docker restart

step 5: 重启容器

docker start centos-desktop-vnc

访问响应的端口，查看是否映射成功。
