I have read through several similar threads but I cant really solve it by myself. My docker image keeps filling up. The way I can mitigate this is removing dangling images.

 

I understand that this should be caused because an image is leaking data into the docker image instead of a mounted volume. But I cant find which one and where  

 

Any help is appreciated. My docker image is at 60gb and slowly filling up

Since your user shares are broken:

many mapped host paths don't exist.

 

Disable Docker in Settings until you get that worked out.

Sorry that diagnostics was posted before I made this thread and resolved those problems 

I added a new diagnostics where all the data paths should be back

60G docker.img should be at least twice as much as needed. I run 15-20 containers and they only use about half of 20G.

 

The usual cause of filling docker.img is an application writing to a path that isn't mapped. Each path configured in each application must correspond to a mapped container path, case sensitive.

 

Go to Docker page, click Container Size button, and post the results.

 

I dont think anything is out of ordinary here

That agrees with your docker.img usage from those latest diagnostics. If that usage is growing you need to figure out which application is storing data in unmapped paths.
