low disk space

[paigeadelethompson]

Typically you want to use btrfs for docker, but this will ahve to do:

• /var/cache/xbps is a space hog
• docker ps -aq | xargs -i docker stop {} ; docker ps -aq | xargs -i docker rm {}
• sv stop docker ; cd /var/lib/docker; rm -rf * ; cd ; sv start docker
• docker-compose build; docker-compose up -d

-bash-5.2# docker images

Bought some time..

My experience Ive had better luck with btrfs .. ZFS is probably fine too I have had issues with overlay though where docker rmi didn't free up disk space as I expected but then again I don't run into this problem often in general
