Docker容器修改端口映射

• 先停容器和docker服务

docker stop [容器id]
systemctl stop docker

• 查询容器完整CONTAINER ID

docker inspect【CONTAINER ID】| grep Id

• 修改容器配置文件 hostconfig.json 、config.v2.json

cd /var/lib/docker/containers/容器完整id

hostconfig.json参照已有映射修改、新增

        "10081/tcp": [{
                "HostIp": "",
                "HostPort": "10081"

        ],
        "10081/udp": [{

    },
