The signup stack in ~/signup is running with two signups. The workshop got a bigger room: raise SEAT_LIMIT in app.py from 30 to 40.

curl -s localhost:8000
grep -n SEAT_LIMIT app.py

Edit the file:

Apply the change without restarting Postgres. First see that a plain up -d is not enough:

docker compose up -d
docker compose exec web grep -n SEAT_LIMIT app.py

Rebuild and recreate:

docker compose up -d --build
docker compose exec web grep -n SEAT_LIMIT app.py

Now remove the stack while keeping the data, check the volume, and bring it back:

docker compose down
docker volume ls
docker compose up -d
curl -s localhost:8000

The workshop is over. Remove everything, including the database:

docker compose down -v
docker volume ls
