Docker Desktop for Mac Edge release notes

Estimated reading time: 67 minutes

This page contains information about Docker Desktop Edge releases. Edge releases give you early access to our newest features. Note that some of the features may be experimental, and some of them may not ever reach the Stable release.

Docker Desktop Community 2.3.1.0

2020-05-20

Download

New

Docker Desktop introduces a directory caching mechanism to greatly improve disk performance in containers. This feature uses mutagen.io to sync files between the host and the containers and benefits from native disk performance. For more information, see Mutagen-based caching.

We appreciate you trying out an early version of the Mutagen file sync feature. Please let us know your feedback by creating an issue in the Docker Desktop for Mac GitHub repository with the Mutagen label.

Upgrades

Bug fixes and minor changes

Docker Desktop Edge 2.3.0.0 fixes one issue reported on the docker/for-mac GitHub repository.

2020-04-02

Download

Upgrades

New

  • Docker Desktop introduces a new onboarding tutorial upon first startup. The Quick Start tutorial guides users to get started with Docker in a few easy steps. It includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.

Bug fixes and minor changes

Docker Desktop Edge 2.2.3.0 fixes 7 issues reported on the docker/for-mac GitHub repository.

  • Reduced the size of the Docker Desktop installer from 710 MB to 445 MB.
  • Removed dangling /usr/local/bin/docker-machine symlinks which avoids custom installs of docker-machine being accidentally deleted in future upgrades. Note that if you have installed Docker Machine manually, then the install might have followed the symlink and installed Docker Machine in /Applications/Docker.app. In this case, you must manually reinstall Docker Machine after installing this version of Docker Desktop. Fixes docker/for-mac#4208.
  • Fixed a bug where the Docker UI could be started without the engine.
  • Switched from ahci-hd to virtio-blk to avoid an AHCI deadlock, see moby/hyperkit#94 and docker/for-mac#1835.
  • Capturing diagnostics is now faster and easier.
  • Fixed an issue where a container port could not be exposed on a specific host IP. See docker/for-mac#4209.
  • Kubernetes: Persistent volumes created by claims are now stored in the virtual machine. Fixes docker/for-win#5665.
  • Removed port probing from dashboard, just unconditionally showing links to ports that should be available. Fixes docker/for-mac#4264.

Known issues

  • Loopback and unspecified IPv6 addresses (:: and ::1) within a container do not currently work. Some web servers and other programs may be using these addresses in their configuration files.

Docker Desktop Community 2.2.2.0

2020-03-02

Download

This release contains a Kubernetes upgrade. Note that your local Kubernetes cluster will be reset after installing Docker Desktop.

Upgrades

Docker Desktop Community 2.1.7.0

2019-12-11

Download

Note: Docker Desktop Edge 2.1.7.0 is the release candidate for the upcoming major Stable release. Please help us test this version before the wider release and report any issues in the docker/for-mac GitHub repository.

  • Fixed an issue that caused the ‘back’ button on the Dashboard UI to behave inconsistently when repeatedly switching between the container details and the Settings window.
  • Various minor improvements to the Dashboard UI.
  • Fixed an issue that occurs when sharing overlapping directories.
  • Fixed a bug that prevented users from changing the location of the VM disk image.
  • Docker Desktop does not inject inotify events on directories anymore as these can cause mount points to disappear inside containers. Fixes docker/for-mac#3976.
  • Fixed an issue that caused Docker Desktop to fail on startup when there is an incomplete Kubernetes config file.
  • Fixed an issue where attempts to log into Docker through Docker Desktop could sometimes fail with the Incorrect authentication credentials error. Fixes docker/for-mac#4010.

Bug fixes and minor changes

  • Fixed port forwarding when containers are using overlay networks.
  • Fixed a container start error when a container has more than one port with an arbitrary or not-yet-configured external port number. For example, docker run -p 80 -p 443 nginx. Fixes docker/for-win#4935 and docker/compose#6998.

Docker Desktop Community 2.1.5.0

2019-11-04

Download

This release contains a Kubernetes upgrade. Note that your local Kubernetes cluster will be reset after installation.

Upgrades

New

Docker Desktop Dashboard: The new Docker Desktop Dashboard provides a user-friendly interface which enables you to interact with containers and applications, and manage the lifecycle of your applications directly from the UI. In addition, it allows you to access the logs, view container details, and monitor resource utilization to explore the container behavior.

To access the new Dashboard UI, select the Docker menu from the Mac menu bar and then click Dashboard.

Bug fixes and minor changes

Fixed an issue that caused VMs running on older hardware with macOS Catalina to fail on startup with the error processor does not support desired secondary processor-based controls.

Known issues

  • When you start a Docker Compose application and then start a Docker App which has the same name as the Compose application, Docker Desktop displays only one application on the Dashboard. However, when you expand the application, containers that belong to both applications are displayed on the Dashboard.

  • When you deploy a Docker App with multiple containers on Kubernetes, Docker Desktop displays each Pod as an application on the Dashboard.

Docker Desktop Community 2.1.4.0

2019-09-09

Download

Upgrades

Bug fixes and minor changes

  • Reduced the Virtual Machine (VM) startup time.
  • Added support for Expect: 100-continue headers in the Docker API proxy. Some HTTP clients such as curl send this header when the payload is large, for example, when creating containers. Fixes moby/moby#39693.

  • Upgrades
  • Bug fixes and minor changes
  • New
    • For systems running APFS on SSD on High Sierra, use raw format virtual machine disks by default. This increases 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 “Reset to factory defaults”. To query the space usage of the file, use a command like: $ cd ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/ $ ls -ls Docker.raw 3944768 -rw-r--r--@ 1 user staff 68719476736 Nov 16 11:19 Docker.raw The first number (3944768) is the allocated space in blocks; the larger number 68719476736 is the maximum total amount of space the file may consume in future in bytes.

Beta 13 Release Notes (2016-05-25 1.11.1-beta13)

New

  • osxfs: Enabled 10ms dcache for 3x speedup on a go list ./... test against docker/machine. Workloads heavy in file system path resolution (common among dynamic languages and build systems) will have those resolutions performed in amortized constant time rather than time linear in the depth of the path so speedups of 2-10x will be common.

  • Support multiple users on the same machine, non-admin users can use the app as long as vmnetd has been installed. Currently, only one user can be logged in at the same time.

  • Basic support for using system HTTP/HTTPS proxy in docker daemon

Known issues

  • Docker.app sometimes uses 200% CPU after macOS wakes up from sleep mode. The issue is being investigated. The workaround is to restart Docker.app.

Bug fixes and minor changes

  • osxfs:
    • setting atime and mtime of nodes is now supported
    • Fixed major regression in Beta 12 with ENOENT, ENOTEMPY, and other spurious errors after a directory rename. This manifested as npm install failure and other directory traversal issues.
    • Fixed temporary file ENOENT errors
    • Fixed in-place editing file truncation error, such as when running perl -i
  • improved time synchronisation after sleep
