Docker Desktop Community 2.1.5.0 Release Notes: Kubernetes Upgrade, Dashboard, WSL 2 Backend, and File Sharing Improvements

- 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](https://github.com/docker/for-win/issues/4935) and [docker/compose#6998](https://github.com/docker/compose/issues/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. - Injected Docker CLI, CLI plugins, Docker Compose, Notary, and kubectl into WSL distributions when Docker Desktop WSL integration is enabled. - Fixed an issue where bind mounts created with Docker Compose from a WSL distribution were incorrectly translated. Fixes [docker/for-win#5084](https://github.com/docker/for-win/issues/5084). - Docker Desktop now supports inotify events on shared filesystems for Windows file sharing. - Fixed a cache invalidation bug when a file in a shared volume is renamed on the host for Windows file sharing. - Fixed a handle leak when calling `Mknod` on a shared volume for Windows file sharing. - To make VM startup more reliable, Docker Desktop now avoids adding a Hyper-V NIC to the Windows VM when using Hypervisor sockets for Windows file sharing (rather than Samba). ### Known issue Windows Insider Preview Slow Ring users running OS builds older than 19025 cannot run WSL 2 following upgrade to Docker Desktop Edge 2.1.6.0. WSL 2 requires Windows 10 Insider Preview build 19018 or greater. ## Docker Desktop Community 2.1.5.0 2019-11-04 This release contains a Kubernetes upgrade. Note that your local Kubernetes cluster will be reset after installation. ### Upgrades - [Kubernetes 1.15.5](https://github.com/kubernetes/kubernetes/releases/tag/v1.15.5) - [Docker Compose 1.25.0-rc4](https://github.com/docker/compose/releases/tag/1.25.0-rc4) - Linux kernel 4.19.76 ### 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 Dashboard UI, select the Docker menu from the system tray and then click **Dashboard**. - **WSL 2 backend:** The new Docker Desktop WSL 2 backend replaces the Docker Desktop WSL 2 Tech Preview. The 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](/manuals/desktop/features/wsl/_index.md). - **New file sharing implementation:** Docker Desktop introduces a new file sharing implementation which uses gRPC, FUSE, and Hypervisor sockets instead of 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 the 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. > To switch back to the Samba file system: > > From the Docker menu, select **Settings** > **Command line**, and then clear the **Enable experimental features** check box. Alternatively, install a Docker Desktop Stable release. ### 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 version 2.1.5.0 introduces a Kubernetes upgrade to 1.15.5, along with updates to Docker Compose and the Linux kernel. New features include the Docker Desktop Dashboard for container and application management, a WSL 2 backend for improved Kubernetes support and networking, and a new gRPC-based file sharing implementation offering better I/O performance. Bug fixes address issues related to container port configurations, Docker Desktop crashes during factory resets, Fast Startup, WSL integration, bind mounts, and file sharing. Known issues include a conflict in the Dashboard when Docker Compose and Docker App share the same name, and the display of Kubernetes Pods as individual applications. Additionally, a compatibility issue is noted for Windows Insider Preview users with older OS builds.
