Docker无法连接到覆盖ipv6网络

Question

我创建了docker网络

docker network create --driver=overlay --ipv6 --attachable cqxipv6

docker network inspect cqxipv6表明

    {
        "Name": "cqxipv6",
        "Id": "u1t2l7jdze89sey8j9oed9az8",
        "Created": "0001-01-01T00:00:00Z",
        "Scope": "swarm",
        "Driver": "overlay",
        "EnableIPv6": true,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": []
        },
        "Internal": false,
        "Attachable": true,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": null,
        "Options": {
            "com.docker.network.driver.overlay.vxlanid_list": "4098"
        },
        "Labels": null
    }
]

我试图使用创建的网络运行容器

docker run -it --name mydocker --rm --network cqxipv6 hub.docker.com/centos:centos6.8 /bin/bash

我收到了这个错误

docker: Error response from daemon: attaching to network failed, make sure your network options are correct and check manager logs: context deadline exceeded.

知道这是什么意思以及如何解决它？

谢谢

提供子网后问题消失了

docker network create --driver overlay --ipv6 --subnet=2001:3984:3989::/80 --attachable cqxipv6
