Docker Compose v1.23.0-rc3 Release Notes

Release Date: 2018-10-17 // over 5 years ago

  • 🏁 If you're a Mac or Windows user, the best way to install Compose and keep it up-to-date is Docker for Mac and Windows.

    🏁 Docker for Mac and Windows will automatically install the latest version of Docker Engine for you.

    ⬆️ Alternatively, you can use the usual commands to install or upgrade Compose:

    curl -L https://github.com/docker/compose/releases/download/1.23.0-rc3/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

    👀 See the install docs for more install options and instructions.

    Important note

    0️⃣ The default naming scheme for containers created by Compose in this version
    has changed from <project>_<service>_<index> to
    <project>_<service>_<index>_<slug>, where <slug> is a randomly-generated
    ⚡️ hexadecimal string. Please make sure to update scripts relying on the old
    ⬆️ naming scheme accordingly before upgrading.

    🔋 Features

    🔊 Logs for containers restarting after a crash will now appear in the output
    🔊 of the up and logs commands.

    ➕ Added --hash option to the docker-compose config command, allowing users
    🔧 to print a hash string for each service's configuration to facilitate rolling
    ⚡️ updates.

    Output for the pull command now reports status / progress even when pulling
    multiple images in parallel.

    For images with multiple names, Compose will now attempt to match the one
    🔧 present in the service configuration in the output of the images command.

    🛠 Bugfixes

    Parallel run commands for the same service will no longer fail due to name
    collisions.

    🛠 Fixed an issue where paths longer than 260 characters on Windows clients would
    🏗 cause docker-compose build to fail.

    🛠 Fixed a bug where attempting to mount /var/run/docker.sock with
    🏁 Docker Desktop for Windows would result in failure.

    The --project-directory option is now used by Compose to determine where to
    look for the .env file.

    🏗 docker-compose build no longer fails when attempting to pull an image with
    credentials provided by the gcloud credential helper.

    🛠 Fixed the --exit-code-from option in docker-compose up to always report
    the actual exit code even when the watched container isn't the cause of the
    exit.

    🛠 Fixed an issue that would prevent recreating a service in some cases where
    a volume would be mapped to the same mountpoint as a volume declared inside
    🐳 the image's Dockerfile.

    🛠 Fixed a bug that caused hash configuration with multiple networks to be
    inconsistent, causing some services to be unnecessarily restarted.

    🛠 Fixed a bug that would cause failures with variable substitution for services
    with a name containing one or more dot characters

    🛠 Fixed a pipe handling issue when using the containerized version of Compose.

    🛠 Fixed a bug causing external: false entries in the Compose file to be
    🐳 printed as external: true in the output of docker-compose config

    🛠 Fixed a bug where issuing a docker-compose pull command on services
    without a defined image key would cause Compose to crash

    Volumes and binds are now mounted in the order they're declared in the
    service definition

    Miscellaneous

    • ⚡️ The zsh completion script has been updated with new options, and no
      longer suggests container names where service names are expected.
