Docker Desktop 3.3.0

2021-04-08

New

You can now specify when to download and install a Docker Desktop update. When an update becomes available, Docker Desktop displays an icon to indicate the availability of a newer version. You can download the update in the background whenever convenient. When the download is complete, all you need to do is to click Update and restart to install the latest update.

Developers who use Docker Desktop for professional development purposes may at times need to skip a specific update. For this reason, Pro or Team subscription developers can skip notifications for a particular update when a reminder appears.

For developers in IT managed environments, who don’t have administrative access to install updates to Docker Desktop, there is now an option in the Settings menu to opt out of notifications altogether for Docker Desktop updates if your Docker ID is part of a Team subscription.

Upgrades

Bug fixes and minor changes

Fixed an issue when viewing compose applications that have been started with an explicit project name. Fixes docker/for-win#10564.

WSL 2

Swarm service bind mounts are not always restored correctly.
Bind mounts of files living outside of the root mount point (files within /mnt/c, /tmp, /run...) don’t work correctly when multiple containers mount them.

```

Docker Desktop Community 2.2.0.3

Starting with Docker Desktop 2.2.0.3, you must access all shared files using their original case. For example, if you have created a file called test, you must open it as test. Attempts to open the file as Test will fail with the error No such file or directory. For more information, see Tips on shared drives, permissions, and volume mounts in File sharing.

Known issues

DockerNAT has been removed from Docker Desktop 2.2.0.0 as using an IP address to communicate from the host to a container is not a supported feature. To communicate from a container to the host, you must use the special DNS name host.docker.internal. We also recommend using ports to communicate from the host to a container. For more information, see Networking.

However, if your current setup relies on IP addresses for communication, you can use a temporary workaround to reinstate DockerNAT. To do this, open C:\Program Files\Docker\Docker\resources\MobyLinux.ps1 and add $SwitchName = "DockerNAT" between line 175 and 176. Note that the temporary workaround to reinstate DockerNAT may be removed from future releases.
Directory junctions in shared volumes pointing outside the shared volume do not work.
It is currently not possible to rename open files within shared volumes.
In some cases, Docker containers do not synchronize time with the host when the host machine is put to sleep.
It is not possible to use localhost in the proxy settings. You can instead use host.docker.internal to work around this issue.

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.
WSL 2 backend: The experimental Docker Desktop WSL 2 backend architecture introduces support for Kubernetes, provides an updated Docker daemon, offers VPN-friendly networking, and additional features. For more information, see Docker Desktop WSL 2 backend.
New file sharing implementation: Docker Desktop introduces a new file sharing implementation that replaces Samba, CIFS, and Hyper-V networking. The new implementation offers improved I/O performance. Additionally, when using the new file system:
- Users don’t have to expose the Samba port, and therefore do not experience issues related to IT firewall or drive-sharing policy.
- There is no need to provide user credentials to Docker Desktop. File access rights are automatically enforced when accessing mounted folders through containers.
  
  For more information, see the blog post New file sharing implementation in Docker Desktop Windows.
Added the WSL Integration option in Settings > Resources to select WSL 2 distributions. This option will be visible only after enabling WSL 2 on your machine.
Introduced a new user interface for the Docker Desktop Settings 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

Enabled Windows features such as Hyper-V and Containers during installation, thereby reducing the need for another restart after installation.
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.
Docker Machine is no longer included in the Docker Desktop installer. You can download it separately from the Docker Machine releases page.
Docker Desktop now automatically restarts after an update.
Fixed an issue where Docker Desktop auto-start was not being disabled properly on some machines.
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 which caused Docker Desktop to crash when resetting to factory defaults while running Windows containers.
Fixed multiple issues related to Fast Startup.
Docker Desktop now supports inotify events on shared filesystems.
Docker Desktop startup is now more reliable and does not clash with host firewall software.
Fixed a rare issue that caused to Docker Desktop to crash with the error Unable to stop Hyper-V VM: Cannot validate argument on parameter 'SwitchName'. The argument is null or empty.
Fixed a bug that caused a rare crash when uninstalling Docker Desktop.
Fixed an issue that caused Docker Desktop to fail on startup when there is an incomplete Kubernetes config file.
Fixed various stability issues.

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.
