for a very low resource machine it may be useful to pull the docker images from docker hub

docker compose pull
docker compose up

for a full local build from source

docker compose build
docker compose up

• set an admin password and access the admin web interface at https://domain-name/admin/

to keep the service running

docker compose up -d

to get the phoenix server seed words

sudo cat /var/lib/docker/volumes/hub_phoenix_data/_data/seed.dat ; echo

to delete the database

sudo rm /var/lib/docker/volumes/hub_card_data/_data/cards.db

notes

• consider debian-12.6 or alpine-3.14 instead of ubuntu-22.04 to save disk space
