Watchtower not triggering database migrations on UAT

[pgwillia]

Describe the bug
Migrations are not being run when Watchtower triggers an update to the container.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://era.uat.library.ualberta.ca
2. Search for anything
3. See 500 error page

Expected behavior
When a container is updated, run all migrations and precompile assets.

Additional context
This was an example of an error that was the result of not running a migration

Watchtower does have hooks for this purpose. Something about this is not working:

jupiter/docker-compose.production.yml

Line 64 in 0a08d0d

Still experiencing this!

Might not be watchtower specific. Seems like the whole db is wiped clean.
