Yesterday I had a strange problem with Docker during a build process. I use Linux Mint. I didn’t have enough space at the main system directory /. By default, Docker saves all data (images, volumes, etc.) in /var/lib/docker. Firstly I wanted to move this directory to the /home, but unfortunately, there was probably a problem with encryption, and Docker’s daemon couldn’t start properly. The second option was to move the directory to a hdd drive. But it also wasn’t a piece of cake (just Linux user normal day 😀 ).
