As a developer, I will usually install Git on my systems. Not only provides it the version control service, but in Windows it does add the Git-Bash: a set of Linux-tools based on Cygwin. So I can work the same way on my Windows box like on my Linux PC.
Further I like it to contain development environments for different projects in their own Docker container without polluting one another or the host with left-overs.
Win10 and WSL
Since the new laptop came with Windows 10, I could run the Windows Subsystem for Linux aka WSL. Winaero has a serias of articles giving a good overview of the WSL features. I did chose the Debian installation. The first impression was very positive. One could even run a X-Server on the Windows host and use it from X11 client applications in the WSL environment.
But there is a downside which prevent me from using WSL: Git-Bash/Cygwin is a very thin layer on top of Windows. It can easily access and run most Windows-native applications. E.g. you install Python for Windows and use it within Git-Bash. WSL on the other hand behaves more like a separate Linux system with its own file system, so you cannot use Windows executables. From this follows that, if you need native Git on WIndows (e.g. for IDE integration), you still must install Git and Git-Bash.
Win10 and Docker
Since WSL only provides user space compatibility, it is impossible to run Docker-daemon on WSL. Now you could argue, that Win10 can run Docker natively. Well, this is true only for Win10 Pro and above. Win10 Home is missing the necessary Hyper-V-infrastructure.
WSL is an interesting concept, but does currently not fit into my development workflow. If you are confined to Win10 Home but have enough cores and memory, VirtualBox allows you to run real Linux boxes on your Windows system. On those you can run Docker without restrictions. Then there is no need for WSL, since VirtualBox provides a better Linux environment and Git-Bash/Cygwin provides better integration into your Windows system.
Two questions remain:
- Since Podman does not need a daemon, could it run containers in WSL?
- I should check on the office laptop, if native Docker on Win10 Enterprise is an option to skip the VirtualBox layer.
