This is a pre-release of the upcoming 23.0.0 release.

Pre-releases are intended for testing new releases: only install in a test environment!

curl -fsSL https://get.docker.com -o get-docker.sh
sudo CHANNEL=test sh get-docker.sh

Starting with the 23.0.0 release, we're moving away from using CalVer versioning, and use versioning that's using SemVer format. Changing the version format is a stepping-stone towards go module compatibility, but the repository does not yet use go-modules, and still requires using a "+incompatible" version; we'll be working towards go module compatibility in a future release.

Known issues:

• There is no changelog yet; an overview of pull requests included in this release can be found on GitHub:

  • docker cli: all pull requests for 23.0.0 / all "changelog" pull requests for 23.0.0
  • docker engine: all pull requests for 23.0.0 / all "changelog" pull requests for 23.0.0

• Static binaries (.tar.gz) are no longer include cli plugins; use the deb/rpm packages, or manual installation instructions from the buildx github repository and docker compose github repository

• Static binaries for dockerd are broken on armhf and armel (32-bit).

• There are no packages available yet for the s390x and ppc64le architectures

• The docker-buildx-plugin .deb package for 0.10.0-rc2 had an incorrectly formatted version-string, causing it to be installed instead of the 0.10.0 (non-pre-release) version. To install v0.10.0 of buildx instead of the 0.10.0-rc2 pre-release, specify the version to install. For example, if you're on Ubuntu 22.04 "jammy", use apt-cache to find the available versions of the docker-buildx-plugin package:

  apt-cache madison docker-buildx-plugin
  docker-buildx-plugin | 0.10.0-rc2~ubuntu-jammy | https://download-stage.docker.com/linux/ubuntu jammy/test amd64 Packages
  docker-buildx-plugin | 0.10.0-1~ubuntu.22.04~jammy | https://download-stage.docker.com/linux/ubuntu jammy/test amd64 Packages
  docker-buildx-plugin | 0.9.1~ubuntu-jammy | https://download-stage.docker.com/linux/ubuntu jammy/test amd64 Packages
  ...
  

  In this case, the version to specify is 0.10.0-1~ubuntu.22.04~jammy;

  apt-get install docker-buildx-plugin=0.10.0-rc2~ubuntu-jammy
