My system has two partitions:

• 5G main partition where Ubuntu is installed
• 100G side partition at /mnt/eda that I'd like to use for Docker container runs

I need to start multiple Docker containers that will take up >10G additional disk space after they're launched. I want them to use disk space form /mnt/eda, but how do I do that?

Currently, whenever I import or run a container, space from my main partition is taken up. I tried downloading the binary and starting it from the side partition, but space from main partition was still being used up.

I can't attach/mount drives to my containers -- they must be completely separate from the host for security.

Sure, no problem!

You can:

• mount the partition on /var/lib/docker
• make a symlink; e.g. from /var/lib/docker to /mnt/eda/docker
• bind-mount e.g. /mnt/eda/docker to /var/lib/docker
