Docker Desktop is probably the most common way to work with Linux containers on Windows 10. Also, Microsoft continues to improve Windows 10 and offers with the Windows Subsystem for Linux a very good platform to work natively with Linux. Microsoft is currently preparing a new version of WSL 2, which for the first time brings a real Linux kernel. This makes operation of the Docker Engine under WSL possible. Microsoft and Docker are working closely together to optimally enable the running of Linux containers under WSL 2. This talk will show what is going to improve on Docker Desktop on the upcoming Windows 10 version 20H1. The current status can already be tried out with the Windows Insider program and the Technical Preview of Docker Desktop.
