Docker for Mac Stable release notes

Estimated reading time: 20 minutes

Here are the main improvements and issues per stable release, starting with the current release. The documentation is updated for each release.

For system requirements, see What to know before you install.

Release notes for stable releases are listed below, edge release notes are also available. (Following the CE release model, ‘beta’ releases are called ‘edge’ releases.) You can learn about both kinds of releases, and download stable and edge product installers at Download Docker for Mac.

  • Bug fixes and minor changes
    • AUFS storage driver is deprecated in Docker Desktop and AUFS support will be removed in the next major release.

You can check documentation to save images and backup volumes
    • OS X El Captain 10.11 is deprecated in Docker Desktop. You will not be able to install updates after Docker Desktop 18.06.x. We recommend upgrading to the latest version of macOS.

    • Do not allow install of Docker for Mac on macOS Yosemite 10.10, this version is not supported since Docker for Mac 17.09.0.
    • Fix button order in reset dialog windows. Fixes docker/for-mac#2827
    • Fix upgrade straight from pre-17.12 versions where Docker for Mac cannot restart once the upgrade has been performed. Fixes docker/for-mac#2739

  • Bug fixes and minor changes
    • Fix daemon not starting properly when setting TLS-related options. Fixes docker/for-mac#2663
    • DNS name host.docker.internal should be used for host resolution from containers. Older aliases (still valid) are deprecated in favor of this one. (See https://tools.ietf.org/html/draft-west-let-localhost-be-localhost-06).

Download

  • Bug fixes and minor changes
    • Revert the default disk format to qcow2 for users running macOS 10.13 (High Sierra). There are confirmed reports of file corruption using the raw format which uses sparse files on APFS. Note this change only takes effect after a reset to factory defaults (from the Whale menu -> Preferences -> Reset). Related to docker/for-mac#2625
    • Fix VPNKit proxy for docker.for.mac.http.internal.

Docker Community Edition 17.12.0-ce-mac49 2018-01-19

Download

  • Bug fixes and minor changes

    • VM entirely built with Linuxkit
    • VM disk size can be changed in disk preferences. (See docker/for-mac#1037)
    • For systems running APFS on SSD on High Sierra, use raw format VM disks by default. This improves disk throughput (from 320MiB/sec to 600MiB/sec in dd on a 2015 MacBook Pro) and disk space handling. Existing disks are kept in qcow format, if you want to switch to raw format you need to “Remove all data” or “Reset to factory defaults”. See https://docs.docker.com/docker-for-mac/faqs/#disk-usage
    • DNS name docker.for.mac.host.internal should be used instead of docker.for.mac.localhost (still valid) for host resolution from containers, since since there is an RFC banning the use of subdomains of localhost. See https://tools.ietf.org/html/draft-west-let-localhost-be-localhost-06.
  • Bug fixes and minor changes
    • Display various component versions in About box.
    • Avoid VM reboot when changing host proxy settings.
    • Don’t break HTTP traffic between containers by forwarding them via the external proxy. (See docker/for-mac#981)
    • Filesharing settings are now stored in settings.json.
    • Daemon restart button has been moved to settings / Reset Tab.
    • Better VM state handling & error messages in case of VM crashes.
    • Fix login into private repository with certificate issue. (See docker/for-mac#2201)
