Docker Desktop Community 2.4.0.0

2020-09-30

Docker Desktop 2.4.0.0 contains a Kubernetes upgrade. Your local Kubernetes cluster will be reset after installing this version.

New

Docker Compose CLI - 0.1.18, enabling use of volumes with Compose and the Cloud through ECS and ACI.
Docker introduces the new Images view in the Docker Dashboard. The images view allows users to view the Hub images, pull them and manage their local images on disk including cleaning up unwanted and unused images. To access the new Images view, from the Docker menu, select Dashboard > Images.
Docker Desktop now enables BuildKit by default after a reset to factory defaults. To revert to the old docker build experience, go to Preferences > Docker Engine and then disable the BuildKit feature.
Amazon ECR Credential Helper
Docker Desktop now uses much less CPU when there are lots of file events on the host and when running Kubernetes, see docker/roadmap#12.
Docker Desktop now uses gRPC-FUSE for file sharing by default. This uses much less CPU than osxfs, especially when there are lots of file events on the host. To switch back to osxfs, go to Preferences > General and disable gRPC-FUSE.

Bug fixes and minor changes

Docker Desktop on macOS 10.13 is now deprecated.
Removed the legacy Kubernetes context docker-for-desktop. The context docker-desktop should be used instead. Fixes docker/for-win#5089 and docker/for-mac#4089.
Adding the application to the dock and clicking on it will launch the container view if Docker is already running.
Added support for emulating Risc-V via Qemu 4.2.0.
Removed file descriptor limit (setrlimit) of 10240. We now rely on the kernel to impose limits via kern.maxfiles and kern.maxfilesperproc.
Fixed a Mac CPU usage bug by removing the serial console from hyperkit, see docker/roadmap#12. To open a shell in the VM use either nc -U ~/Library/Containers/com.docker.docker/Data/debug-shell.sock.
Copy container logs without ansi colors to clipboard. Fixes docker/for-mac#4786.
Fixed automatic start on log in. See [docker/for-mac#4877] and [docker/for-mac#4890].
Fixed bug where the application won't start if the username is too long.
Fixed a bug where adding directories like /usr to the filesharing list prevents Desktop from starting. Fixes docker/for-mac#4488
Fixed application startup if hosts is specified inside the Docker daemon.json. See docker/for-win#6895
Docker Desktop always flushes filesystem caches synchronously on container start. See docker/for-mac#4943.
Compose-on-Kubernetes is no longer included in the Docker Desktop installer. You can download it separately from the compose-on-kubernetes release page.

Known issues

There is a known issue when using docker-compose with named volumes and gRPC FUSE: second and subsequent calls to docker-compose up will fail due to the volume path having the prefix /host_mnt. To work around this issue, switch back to osxfs in Settings. See docker/for-mac#4859.
There is a known issue when enabling Kubernetes where the settings UI fails to update the Kubernetes state. To work around this issue, close and re-open the window.
There is a rare known issue when switching users where the images view continues to show the repositories of the previous user. To work around this issue, close and re-open the window.

Docker Desktop Community 2.3.0.5

2020-09-15

New

The new Cloud integration in Docker CLI makes it easy to run containers in the cloud using either Amazon ECS or Microsoft ACI.

Bug fixes and minor changes

Fixed automatic start on log in. See docker/for-mac#4877 and docker/for-mac#4890

Known issues

The clock_gettime64 system call returns EPERM rather than ENOSYS in i386 images. To work around this issue, disable seccomp by using the --privileged flag. See docker/for-win#8326.

Docker Desktop Community 2.3.0.4

2020-07-27

Fixed a performance regression when using shared volumes in 2.2.0.5. Fixes [docker/for-mac#4423].

Docker Desktop Community 2.2.0.5

2020-04-02

Bug fixes and minor changes

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.

2020-02-11

Upgrades

Docker Desktop Community 2.2.0.0

2020-01-21

Docker Desktop 2.2.0.0 contains a Kubernetes upgrade. Your local Kubernetes cluster will be reset after installing this version.

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. For detailed information about the new Dashboard UI, see Docker Desktop Dashboard.
Introduced a new user interface for the Docker Desktop Preferences menu.
The Restart, Reset, and Uninstall options are now available on the Troubleshoot menu.
Added the ability to start and stop existing Compose-based applications and view combined logs in the Docker Desktop Dashboard UI.

Bug fixes and minor changes

Added missing completions for the fish shell for Docker Compose. Fixes docker/for-mac#3795.
Fixed a bug that did not allow users to copy and paste text in the Preferences > Daemon window. Fixes docker/for-mac#3798.
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.
Added a loading overlay to the Settings and Troubleshoot windows to prevent editing conflicts.
Deactivated the Reset Kubernetes button when Kubernetes is not activated.
Improved the navigation in Settings and Troubleshoot UI.
Fixed a bug in the UEFI boot menu that sometimes caused Docker Desktop to hang during restart. Fixes docker/for-mac#2655 and docker/for-mac#3921.
Docker Desktop now allows users to access the host’s SSH agent inside containers. Fixes docker/for-mac#410
Docker Machine is no longer included in the Docker Desktop installer. You can download it separately from the Docker Machine releases page.
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.
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.
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.

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.

Kitematic 0.17.8

Bug fixes and minor changes

All binaries included in Docker Desktop are now notarized so that they can run on macOS Catalina. For more information, see Notarization Requirement for Mac Software.

Selecting the ‘Experimental features’ checkbox in the Daemon Preferences menu turns on experimental features for Docker daemon and Docker CLI.
Improved the reliability of com.docker.osxfs trace performance profiling command. Users can now run the com.docker.osxfs trace --summary option for a high-level summary of operations, instead of receiving a trace of all operations.
Docker Desktop now supports large lists of DNS resource records on Mac. Fixes docker/for-mac#2160.

Experimental

Experimental features provide early access to future product functionality. These features are intended for testing and feedback only as they may change between releases without warning or can be removed entirely from a future release. Experimental features must not be used in production environments. Docker does not offer support for experimental features.

Docker Desktop Community 2.1.0.0 contains the following experimental features.

Docker App: Docker App is a CLI plugin that helps configure, share, and install applications. For more information, see Working with Docker App.
Docker Buildx: Docker Buildx is a CLI plugin for extended build capabilities with BuildKit. For more information, see the Build page.

Bug fixes and minor changes

Docker Desktop now allows users to expose privileged UDP ports. docker/for-mac#3775
Fixed an issue where running some Docker commands can fail if you are not using Credential Helpers. docker/for-mac#3785
Changed the host's kubernetes context so that docker run -v .kube:kube ... kubectl works.
Restricted the cluster-admin role on local Kubernetes cluster to kube-system namespace.
Reduced the VM startup time. swap is not created every time a virtual machine boots.
Fixed Kubernetes installation with VPNkit subnet.
Fixed a bug where the process output was not redirected to stdout when gathering diagnostics on Windows, which sometimes resulted in a crash.
Added /etc/machine-id to the virtual machine. Fixes docker/for-mac#3554.
Docker Desktop does not send DNS queries for docker-desktop.<domain> every 10s. It now relies on the host’s DNS domain search order rather than trying to replicate it inside the VM.
Removed the ability to log in using email address as a username as the Docker command line does not support this.
Docker Desktop now allows running a Docker registry inside a container. Fixes docker/for-mac#3611.
Fixed a stability issue with the DNS resolver.
Docker Desktop truncates UDP DNS responses which are over 512 bytes in sizes.
Fixed port 8080 that was used on localhost when starting Kubernetes. Fixes docker/for-mac#3522.
Improved error messaging: Docker Desktop does not prompt users to run diagnostics, or to reset to factory default when it is not appropriate.
Kubernetes: Docker Desktop now uses the default maximum number of pods for kubelet. docker/for-mac#3453.
Fixed DockerHelper crash. docker/for-mac#3470.
Fixed binding of privileged ports with specified IP. docker/for-mac#3464
Fixed service log collection in diagnostics.
