我在使用我的 Docker 容器时遇到了问题，具体来说，这个laradock/laravel-horizon容器，我不确定这是否相关。
我遇到的问题是我无法以任何有意义的方式解决容器问题，我可以停止/启动其他容器，但具体不是这个。
docker-composer down成功关闭除 Horizon 之外的所有容器。
$ docker-compose down
Stopping laradock_caddy_1 ... done
Stopping laradock_redis_1 ... done
Stopping laradock_mysql_1 ... done
Stopping laradock_php-fpm_1 ... done
Stopping laradock_workspace_1 ... done
; and it just hangs here indefinitely
我尝试执行的与该特定容器相关的任何操作都只是无限期地挂起。
docker ps显示容器已被终止。尝试启动它时，我
$ docker-compose up -d laravel-horizon
ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
$ docker-compose --verbose up -d laravel-horizon
输出如下。8bafeae5c107eef03c1887656dd9a1d188e6a6198d92da9a64ee1f1da05e9a60是地平线容器。
...

此时我真的不知道该怎么做，解决办法是重启docker。但这个容器的问题似乎向上蔓延，因为尝试重启docker服务也不起作用了。
$ service docker restart
无限期地挂起
$ service docker stop
也无限期挂起。
$ service docker start
Failed to start docker.socket: Transaction is destructive.
See system logs and 'systemctl status docker.socket' for details.
$ systemctl status docker.service

我很茫然，我可以通过重新启动服务器来“修复”该问题，但问题仍然再次出现。
看起来 Docker 本身遇到了问题，我不知道从哪里开始寻找解决方案。
