docker socket：权限被拒绝

  • 772

我有安装了 proxmox 5 的家庭服务器和 docker 容器中的一些服务。直到昨天一切都很好。

我重新启动了服务器，所有容器中的所有服务都无法绑定套接字，因为权限被拒绝。我很沮丧...

这里有一些技术细节

Linux server 4.10.15-1-pve #1 SMP PVE 4.10.15-15 (Fri, 23 Jun 2017 08:57:55 +0200) x86_64 GNU/Linux

Docker version 18.03.0-ce, build 0520e24
docker-compose version 1.20.1, build 5d8c71b

球童 docker-compose.yml

这可能是什么原因？

更新：一些新的细节

    我已将 security_opt 添加到 docker-compose 并且问题已经消失。

     security_opt:
      - apparmor:unconfined

    但我不认为这个选项是一个完全正确的问题解决方案。
