Docker Engine Bugfix und Feature Release 25.0 veröffentlicht

Die Open-Source Containervirtualisierung Docker ermöglicht die Isolierung von Anwendungen in Containern und steht sowohl für Linux, Windows und MacOS zur Verfügung. Die Engine, bzw. Docker -CE erhielt Updates die Fehler korrigieren und zur Stabilität von Docker beitragen.

Docker Engine 25.0 Release Notes

• Deprecated and removed features, see Deprecated Engine Features.
• Changes to the Engine API, see Engine API version history.
• Full List: docker/cli, 25.0.0 milestone
• Full List: moby/moby, 25.0.0 milestone

Note

In earlier versions of Docker Engine, recursive mounts (submounts) would always be mounted as writable, even when specifying a read-only mount. This behavior has changed in v25.0.0, for hosts running on kernel version 5.12 or later. Now, read-only bind mounts are recursively read-only by default.

To get the same behavior as earlier releases, you can specify the bind-recursive option for the --mount flag.

docker run --mount type=bind,src=SRC,dst=DST,readonly,bind-recursive=writable IMAGE

This option isn’t supported with the -v or --volume flag. For more information, see Recursive mounts.

New

• The daemon now uses systemd’s default LimitNOFILE. In earlier versions of Docker Engine, this limit was set to infinity. This would cause issues with recent versions of systemd, where the hard limit was increased, causing programs that adjusted their behaviors based on ulimits to consume a high amount of memory. moby/moby#45534The new setting makes containers behave the same way as programs running on the host, but may cause programs that make incorrect assumptions based on the soft limit to misbehave. To get the previous behavior, you can set LimitNOFILE=1048576.This change currently only affects build containers created with docker build when using BuildKit with the docker driver. Future versions of containerd will also use this limit, which will cause this behavior to affect all containers, not only build containers.If you’re experiencing issues with the higher ulimit in systemd v240 or later, consider adding a system drop-in or override file to configure the ulimit settings for your setup. The Flatcar Container Linux documentation has a great article covering this topic in detail.
