SUSE-SU-2026:20095-1

This update for docker fixes the following issues:

Changes in docker:

• Update to Docker 28.5.1-ce. See upstream changelog online at https://docs.docker.com/engine/release-notes/28/#2851

• Update to Docker 28.5.0-ce. See upstream changelog online at https://docs.docker.com/engine/release-notes/28/#2850

• Update to docker-buildx v0.29.0. Upstream changelog: https://github.com/docker/buildx/releases/tag/v0.29.0

• Remove git-core recommends on SLE. Most SLE systems have installRecommends=yes by default and thus end up installing git with Docker. bsc#1250508

  This feature is mostly intended for developers ("docker build git://") so most users already have the dependency installed, and the error when git is missing is fairly straightforward (so they can easily figure out what they need to install).

• Update to docker-buildx v0.28.0. Upstream changelog: https://github.com/docker/buildx/releases/tag/v0.28.0

• Update to Docker 28.4.0-ce. See upstream changelog online at https://docs.docker.com/engine/release-notes/28/#2840

  • Fixes a nil pointer panic in "docker push". bsc#1248373

• Update warnings and errors related to "docker buildx ..." so that they reference our openSUSE docker-buildx packages.

• Enable building docker-buildx for SLE15 systems with SUSEConnect secret injection enabled. PED-12534 PED-8905 bsc#1247594

  As docker-buildx does not support our SUSEConnect secret injection (and some users depend "docker build" working transparently), patch the docker CLI so that "docker build" will no longer automatically call "docker buildx build", effectively making DOCKERBUILDKIT=0 the default configuration. Users can manually use "docker buildx ..." commands or set DOCKERBUILDKIT=1 in order to opt-in to using docker-buildx.

  Users can silence the "docker build" warning by setting DOCKER_BUILDKIT=0 explicitly.

  In order to inject SCC credentials with docker-buildx, users should use

  RUN --mount=type=secret,id=SCCcredentials zypper -n ...

  in their Dockerfiles, and

  docker buildx build --secret id=SCCcredentials,src=/etc/zypp/credentials.d/SCCcredentials,type=file .

  when doing their builds.

• Update to Docker 28.3.3-ce. See upstream changelog online at https://docs.docker.com/engine/release-notes/28/#2833 CVE-2025-54388 bsc#1247367

• Update to docker-buildx v0.26.1. Upstream changelog: https://github.com/docker/buildx/releases/tag/v0.26.1
