在 Docker 和我的 Debian 专用服务器出现问题后(提供商提供了一些操作系统镜像，但没有 Docker 所需的某些功能，所以我昨天重新编译了 Linux 内核并激活了所需的功能，我遵循了博客中的一些说明)。
现在我很高兴使用 docker 取得了成功，我尝试创建镜像...但出现错误。
$ docker run -d -t -i phusion/baseimage /sbin/my_init -- bash -l

最佳答案
您不应删除 docker 中的 cgroup 支持。否则，当您运行 docker 容器时，您可能会收到类似警告:您的内核不支持内存交换功能，内存交换已丢弃。之类的警告。
一个简单的命令就可以解决问题。
sudo echo 1 > /sys/fs/cgroup/docker/cgroup.clone_children
如果仍然不起作用，请运行以下命令并重新启动 docker 服务:
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.mems
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.cpus
关于linux - Docker cgroup.procs 设备上没有剩余空间，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29961584/
