Docker :添加--privileged后，docker return错误

Question

因为我在/var/lib/docker/containers手动删除了一个运行容器目录，然后--privileged return错误。但它在没有 --privileged.

的情况下工作

$ docker run -d --name=hello --privileged=true hello-world                                                
fd6cdf95eb1ed7617f4580eef556a2f64fff7b9afb144d346af3916d83704de4

Answer 1

建议从其他主机安装docker并将/usr/bin/runc文件复制到有问题的主机

Answer 2

当我创建一个普通容器时，它可以工作，但有一个警告：Your kernel does not support memory limit capabilities or the cgroup is not mounted.。

所以我在 /boot/cmdline.txt 的末尾添加了 cgroup_enable=memory cgroup_memory=1 并重新启动。

然后我所有的问题都解决了，虽然我仍然不知道为什么。
