How much space are you allocating for docker images? This is dependent on your settings as it mounts volumes up to the maximum of the docker limit. It could be as simple as increasing the amount of space available there.

It also could be your actual drive of this computer is at it's limit as well

RAM: 8 GB Swap: 1 GB Virtual disk limit: 64 GB

I am going to bump the disk to 128 GB and report back.

Finished successfully with 128 GB disk limit. Apparently, I have been walking on thin ice all this time 🤷🏻‍♂️
