在Docker和我的Debian专用服务器出现问题后（提供商提供了一些没有Docker所需功能的操作系统映像，所以我昨天重新编译了Linux内核并激活了所需的功能，我在博客中遵循了一些说明）。 / p>
现在我很高兴用docker取得成功我试图创建图像......我有一个错误。

您不应删除docker中的cgroup支持。否则，当您运行docker容器时，可能会收到类似WARNING: Your kernel does not support memory swappiness capabilities, memory swappiness discarded.的警告。
一个简单的命令应该可以解决问题。
sudo echo 1 > /sys/fs/cgroup/docker/cgroup.clone_children
如果仍然无效，请运行以下命令并重新启动docker service：
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.mems
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.cpus

我在debian repos中通过docker-lxc安装了docker，我跟着一个tuto。我尝试了另一个解决方案（成功），我将source.list /etc/apt/source.list从 jessie 更新为 sid ，我删除了docker-lxc并清除了我安装了docker.io
错误已更改。那是mkdir -p /sys/... can't create dir : access denied
所以我在博客中找到了一条评论，我尝试了解决这条教程之前添加的解决方案：
## file /etc/fstab
# cgroup /sys/fs/cgroup cgroup defaults 0 0
并重新启动服务器。

yum install -y libcgroup libcgroup-devel libcgroup-tools
cgclear
service cgconfig restart
mount -t cgroup none /cgroup
vi /etc/fstab
cgroup /sys/fs/cgroup cgroup defaults 0 0
