SD Free Space Issues with Docker

So I am attempting to install Home Assistant in docker on a fresh install on my emonPi running June18 release on an 8GB card. Once image was loaded, I performed the required sudo emonSDexpand.

On attempting to load in the HA install with Docker, I am getting disk full errors. /dev/root is at 97% use. File system looks like this:

>pi@emonpi(rw):/$ df -l

So, my question is how do I free up some more space to get this loaded or is there a trick to push docker/HA in to the /home/pi partition?

Thanks.

Seem to have figured it out. Doubled the googling efforts.

I changed Docker’s storage base directory (where container and images go) using the method outlined here: https://linuxconfig.org/how-to-move-docker-s-default-var-lib-docker-to-another-directory-on-ubuntu-debian-linux

Now have HA running through Docker with plenty of space.
