Last week I was having some problems with my local docker install on my windows 10 machine.
Everthing was working fine and I was using docker for swagger to asciidoc and asciidoc to pdf conversion.
But suddenly the swagger2markup docker was saying that the path to the file does not exists (see image)

I checked on the internet but couldn’t realy find the problem.
Mapping is correct, file is in folder, my C drive is shared in docker settings

I tried another simple docker container to see if this worked. I used the alpine and executed the ‘ls’ command.
Result of this: totally nothing. No error, no list of folder or files, simply nothing.

Again not normal because there ar certainly files in the C:/Users folder.
I tried disabling the share from my docker settings. By doing this the result of the command was already different. Now I got the error that the drive has not been shared.

This is normal behaviour, so I enabled the share again for my C drive.
An by doing this the result was everything was fixed.
The result of the alpine ls command:

And after this successful run I tried again the swagger2markup docker command and yes, this was also working again.

But now the big question remains, what was the initial cause of this problem?
After some thoughts I found the problem.
The day before the problems started I did a thorough cleanup of my computer. One of the steps I took was cleaning the registry with CCleaner tool.
This step made my local docker go completely wacko. But simply by disabling and re-enabling the share, the problem was fixed.
