Using Docker and OverlayFS on Amazon ECS
If you’re using the ECS-optimised Amazon Linux AMI for your ECS instance hosts, the Docker engine on these instances will be using the devicemapper storage driver. Though this is a fine default for many use cases, you might want to switch to use the overlay/overlay2 storage driver. When we were setting up our Buildkite agent cluster on ECS, we found that the default devicemapper storage driver pro
overlay2でレイヤ数が多くてdocker checkpointに失敗するとき - Qiita
Docker 1.13.0ではexperimentalにdocker checkpointが使えます。この機能を使うにはバージョン2.0以上のcriuコマンドが必要ですがCentOS 7 1511のcriuのバージョンは1.6.1なのでこの条件を満たしていません。CentOS 7 1611はまだリリースされていないため http://buildlogs.centos.org/c7.1611.00/criu/20161105151332/2.3-2.el7.x86_64/ にあるcriuのRPMパッケージとこれが要求するRPMパッケージを拝借しました。 まず https://criu.org/Docker にあるlooperと名付けられたコンテナでcheckpointを試したところ問題なく checkpoint/start できました。次に jupyter/minimal-notebook
Friends Don't Let Friends Run Docker on Loopback in Production
I’ve heard negative things about the Fedora|CentOS Docker storage configuration in the past, and while manning the Red Hat booth in San Francisco at DockerCon last week, I spoke to a number of people who’ve experienced these storage issues themselves. Much of the trouble, I think, boils down to how Docker in Fedora and CentOS have shipped with a storage configuration that optimizes for a convenien

まずは、表題の手順だけを簡潔に・・・。そのうち、内部構造も詳しく説明するかも知れません。 参考資料 Fedora22でoverlayfsを使う手順 手順 Fedora22 Serverをインストールして、まずは最新パッケージにアップデートした上で、「石川さんごめんなさい」をします。（overlayfsドライバーがSELinux未対応のため） # dnf -y update # sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config # reboot/etc/sysconfig/dockerのOPTIONSに '-s overlay' を追加します。 OPTIONS='--selinux-enabled -s overlay'Dockerを起動します。 # systemctl enable docker.ser
Add overlayfs graph backend by alexlarsson · Pull Request #7619 · moby/moby
This backend uses the overlayfs union filesystem for containers plus hard link file sharing for images. Each container/image can have a "root" subdirectory which is a plain filesystem hierarchy, or they can use overlayfs. If they use overlayfs there is a "upper" directory and a "lower-id" file, as well as "merged" and "word" directories. The "upper" directory has the upper layer of the overlay, an
