Worker serivce fails to start after machine reboot

[etkeys]

Current behavior

When the host machine reboots, the videodl_worker service is started automatically but fails and becomes inactivated due to database connection error.

Desired behavior

When the host machine reboots, the videodl_worker service should not fail immediately when automatically started due to database connection failure

Notes

• The reason the worker service has this issue and not the web app service is because the worker service immediately tries to connect to the database, while the web app only connects to the database when a user performs an action that requires a database call.

[etkeys]

It appears that systemd services are started before the postgres docker container is restarted. The worker service and web app service should both use systemd auto restart and restart delay. This way if the database is slow to start or goes down, the services will eventually retry connections and automatically become available again.
