Docker Desktop 4.4.3

2022-01-14

Security

Fixed CVE-2021-45449 that affects users currently on Docker Desktop version 4.3.0 or 4.3.1.

Docker Desktop version 4.3.0 and 4.3.1 has a bug that may log sensitive information (access token or password) on the user’s machine during login. This only affects users if they are on Docker Desktop 4.3.0, 4.3.1 and the user has logged in while on 4.3.0, 4.3.1. Gaining access to this data would require having access to the user’s local files.

New

Easy, Secure sign in with Auth0 and Single Sign-on
- Single Sign-on: Users with a Docker Business subscription can now configure SSO to authenticate using their identity providers (IdPs) to access Docker. For more information, see Single Sign-on.
- Signing in to Docker Desktop now takes you through the browser so that you get all the benefits of auto-filling from password managers.

Upgrades

Bug fixes and minor changes

Docker Desktop displays an error if registry.json contains more than one organization in the allowedOrgs field. If you are using multiple organizations for different groups of developers, you must provision a separate registry.json file for each group.
Fixed a regression in Compose that reverted the container name separator from - to _. Fixes docker/compose-switch.
Doing a Reset to factory defaults no longer shuts down Docker Desktop.
Disabled Dashboard shortcuts to prevent capturing them even when minimized or un-focussed. Fixes docker/for-win#12495.

Known issues

Clicking «Proceed to Desktop» after logging in in the browser, sometimes does not bring the Dashboard to the front.
After logging in, when the Dashboard receives focus, it sometimes stays in the foreground even when clicking a background window. As a workaround you need to click the Dashboard before clicking another application window.
The tips of the week show on top of the mandatory login dialog when an organization restriction is enabled via a registry.json file.

Docker Desktop 4.3.0

2021-12-02

Upgrades

Bug fixes and minor changes

Fixed an issue which prevented users from saving files from a volume using the Save As option in the Volumes UI. Fixes docker/for-win#12407.
Fixed an issue that caused Docker Desktop to fail during startup if the home directory path contains a character used in regular expressions. Fixes docker/for-win#12374.
Added a self-diagnose warning if the host lacks Internet connectivity.
Docker Desktop now uses cgroupv2. If you need to run systemd in a container then:
- Ensure your version of systemd supports cgroupv2. It must be at least systemd 247. Consider upgrading any centos:7 images to centos:8.
- Containers running systemd need the following options: --privileged --cgroupns=host -v /sys/fs/cgroup:/sys/fs/cgroup:rw.

Known issue

Docker Dashboard incorrectly displays the container memory usage as zero on Hyper-V based machines. You can use the docker stats command on the command line as a workaround to view the actual memory usage. See docker/for-mac#6076.

Deprecation

The following internal DNS names are deprecated and will be removed from a future release: docker-for-desktop, docker-desktop, docker.for.mac.host.internal, docker.for.mac.localhost, docker.for.mac.gateway.internal. You must now use host.docker.internal, vm.docker.internal, and gateway.docker.internal.
Removed: Custom RBAC rules have been removed from Docker Desktop as it gives cluster-admin privileges to all Service Accounts. Fixes docker/for-mac/#4774.

New

Docker has announced updates and extensions to the product subscriptions to increase productivity, collaboration, and added security for our developers and businesses.

The updated Docker Subscription Service Agreement includes a change to the terms for Docker Desktop.

It requires a paid subscription (Pro, Team, or Business), for as little as $5 a month, for professional use in larger enterprises.
The effective date of these terms is August 31, 2021. There is a grace period until January 31, 2022 for those that will require a paid subscription to use Docker Desktop.
The Docker Pro and Docker Team subscriptions now include commercial use of Docker Desktop.
