Docker cgroup.procs在設備上沒有剩餘空間

Question

Docker和我的專用服務器與Debian發生了一些問題（提供程序提供了一些操作系統映像，但沒有Docker所需的一些功能，所以我昨天重新編譯了Linux內核並激活了所需的功能，我在博客中遵循了一些指導）。

現在，我很高興能與碼頭工人取得成功，我嘗試創建圖像......並且出現錯誤。

Answer 1

我

經由docker-lxc在debian回購安裝搬運工，我也跟着一個的tuto。我嘗試了另一個解決方案（成功），我更新了我的source.list /etc/apt/source.list從jessie到sid，我刪除了docker-lxc用吹掃和我安裝了docker.io。
錯誤更改。這是mkdir -p /sys/... can't create dir : access denied 所以我覺得在博客中評論，我試圖解決它評論這條線之前由教程補充說：

## file /etc/fstab 
# cgroup /sys/fs/cgroup cgroup defaults 0 0 

並重新啓動服務器。

Answer 2

您不應刪除docker中的cgroup支持。否則，當您運行碼頭集裝箱時，您可能會收到警告，如WARNING: Your kernel does not support memory swappiness capabilities, memory swappiness discarded.。

一個簡單的命令應該做的伎倆。

sudo echo 1 > /sys/fs/cgroup/docker/cgroup.clone_children 

如果仍然無法正常工作，下面的命令，然後重新啓動搬運工服務運行：

sudo echo 0 > /sys/fs/cgroup/docker/cpuset.mems 
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.cpus
