Docker ipv6挂了

重启了下服务器，实体机屏幕上就报Docker起不来。查查日志吧

找原因

首先试图手动启动docker，如下：

1
2
3
sudo systemctl start docker.service 
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.

那再试试journalctl -xeu docker.service

没啥用，看不出来啥有问题。那再试试dockerd：

1
2
$ dockerd
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives don't match any configuration option: ip6tab/les

这下挺明显了，daemon配的ipv6好像有问题。
查了下/etc/docker/daemon.json：

12
{
    "registry-mirrors": [
        "https://dockerproxy.com",
        "https://hub-mirror.c.163.com",
        "https://mirror.baidubce.com",
        "https://ccr.ccs.tencentyun.com"
    ],
    "ipv6": true,
    "fixed-cidr-v6": "fd12:3456:789a:1::/64",
    "experimental": true,
    "ip6tab/les": true
}

是有这个选项，之前配nextcloud_aio的时候文档让我加的。不管了，先试试关闭。

结果

还真启动了。dockerd命令输出如下：

1

dockerd                          
INFO[2023-12-02T20:43:21.026752504+08:00] Starting up

dockerd needs to be started with root privileges. To run dockerd in rootless mode as an unprivileged user, see https://docs.docker.com/go/rootless/

那nextcloud会不会有啥问题呢。但那应该是另一篇记录了HHH
