IT teamDone in: Server5 steps

Before you start

1
Connect and check for local changes
SSH to the VPS and run:
cd /opt/femnet-lms-drf
git status --short
It should print nothing. Investigate any local changes before pulling.
2
Back up the database
docker compose exec postgres pg_dump -U femnet -d femnet > dumps/pre-deploy-$(date +%Y%m%d%H%M%S).sql
3
Pull the new code
git pull origin main, then add any new settings to .env that the release notes mention.
4
Rebuild, migrate and restart
docker compose build
docker compose run --rm drf python manage.py migrate
docker compose run --rm drf python manage.py collectstatic --noinput
docker compose up -d --force-recreate drf celery_worker celery_beat
5
Check it is healthy
curl -i https://femnet-api.duckdns.org/health/ should return 200. Check docker compose logs --tail=50 drf for errors, then sign in to the hub and learner app.

Migrations fail.: Do not restart the old containers on a half-migrated database. Read the error, and restore the backup you just took if needed (see Back up and restore data).
