Original GitHub issue: https://github.com/ciur/papermerge/issues/197

Originally assigned to: @ciur on GitHub.

I'm trying to build a custom docker image with app, worker and general configuration files.

I noticed that running the app for the first time generates errors in the worker and app containers because db is not ready yet.

Stopping and restarting the app makes it work but not without errors

Expected
Scripts that check for readyness of the db container before completing initial setup.

Actual
Errors in the app and worker application (is host db ready and accepting connections on 5432)

Info:

OS: QNAP
Browser Firefox
Database PostgreSQL
Papermerge Version built from the 1.4 subdir

Ok, so I built a custom image with the wait-for-it.sh script in the config directory and then use the following command in my docker compose file:

command: ["/opt/app/wait-for-it.sh", "-s", "-t", "60", "db:5432", "--", "/opt/app/startup.sh"]

This starts the containers as it should on first boot. Other boots are much quicker but this to ensure the DB is ready before starting the other containers.

Would it be possible to include this script by default in the docker config files?
