Deployement

You can easily deploy this app with docker compose (production.yml).

docker compose -f production.yml up --build

If you want to run development version, you will need docker. Docker handles frontend, backend and proxies everything to single port.

# Run development environment
docker compose -f development.yml up --build

Backup

By default database backup is stored inside of /data subfolder. To backup postgreSQL database, run:

sudo docker exec -t cover-letter-db pg_dumpall -c -U postgres > cover.bak.sql && gzip cover.bak.sql
