Can't start Shiny apps

[JanKrivanek]

One weird thing is that whan I try to see the apps dirs in hosted OS - thay are not there:

shiny@59cd7497fb50:/$ cd srv/shiny-server/
shiny@59cd7497fb50:/srv/shiny-server$ dir
shiny@59cd7497fb50:/srv/shiny-server$

Despite the specified -v mounting command command, the hosted OS doesn't see the content of the host OS mounted folder. what can be the reason?

When I output docker insepct, I can see that mounts are properly configured and picked:

    "Mounts": [
            {
                "Type": "bind",
                "Source": "/host_mnt/d/Projects/DockedShiny/apps",
                "Destination": "/srv/shiny-server",
                "Mode": "",
                "RW": true,
                "Propagation": "rprivate"
            },
            {
                "Type": "bind",
                "Source": "/host_mnt/d/Projects/DockedShiny/logs",
                "Destination": "/var/log/shiny-server",
                "Mode": "",
                "RW": true,
                "Propagation": "rprivate"
            }
        ],

In the host OS I can see that the shared folder is indeed unempty:

D:\Projects\DockedShiny\apps>dir /b
HonzaVisual18-11-27
TomasVisual1
Whatev1

What can be the reason for the hosted OS to suddenly not properly seeing content of mounted host OS directory?

So I dived into the failing mount and was investigating 100+ possibilities (not shared drive in win; win firewall dropping SMB; docker share option; etc.) And then found this post that got me in a right dirrection:

docker/for-win#25 (comment)

Basically - I've changed my username on thet box recently and docker had cashed the old one. I needed to 'reset credentials' in docker settings -> Shared Drives menu and after that the new images are seeing the host file system correctly!
