Hi @A98, yeah check the partition format as @linuxdev said, if its fat32 or similar, it would limit the max file size. And regarding the output of
docker ps -a
It shows all the containers, running or not running. So if you ran a container with run -it and then exit it, it will still be there using up resources. So usually if you are done with a container you can delete it like:
docker rm CONTAINER_ID
They can also be containers that were used during the docker build phase, but after that they can be deleted as well. If you what to make a full clean up, you can use:
docker rm $(docker ps -a | grep 1 | awk '{print $1}')
Check out the rm flag for docker run, if the container is meant to run and execute only once, it can be an easy to avoid leaving created containers every time you do a docker run. The only thing is that the data on the container will be lost, so if you need to access some output data after the container is done, make sure to map it to a host volume.
