There have been several not so flattering blog entries lately about docker and its maturity level.
I was quite excited to move away from having to use VirtualBox and indeed Docker for Mac works great but on my Windows machine I noticed that the shared folders don’t seem to work.
After clicking, resetting to default and lastly googling, I found this really great blog entry on the MSDN blog that explains the problem and shows ho to fix it.
Lesson for me here – indeed docker is quite unstable/green still, but the good news – community is great and seems getting stronger and stronger.
