Summary

This allows 'postgres' user connection to postgresql db (direct access or
via pgbouncer).
Ultimately, allowing to run swh db init-admin cli for staging/production nodes.

@vsellier we may no longer need it ;)

What's the point of a new swh-admin user (with hardcoded username) when we already set the password of the postgres user?

What's the point of a new swh-admin user (with hardcoded username) when we already set the password of the postgres user?

We wanted to have a user with just the right amount of permission to allow admin commands (instead of using the mother of all super admins ;)

Also the hard-coded name can be changed if that's a problem.

Do you imply it'd be fine to just use "postgres"?

in regards to D4374

(template1 is needed by the swh db create, if we switch to swh db init-admin which does not need it)

The user you're creating is superuser. It's exactly the same as the postgres user.

Also the hard-coded name can be changed if that's a problem.

Do you imply it'd be fine to just use "postgres"?

Yes.

ack, thanks.

unneeded as explained, we can use postgres instead.

On to find a way to allow pgbouncer connection with postgres user.

Allow postgres access to postgres/pgbouncer instead of creating a new swh-admin role

  1. There is no way to drop the simple blocking rules in the puppetlabs module. So the stand has been to redeclare all rules dropping the blocking one. It works as the octocatalog-diff shows.
  1. Tried to declare it as yaml to no avail so far. That should not be a blocker for now though. We can always try that back at another time (we already spent too much time on this).
This revision is now accepted and ready to land.Oct 30 2020, 2:33 PM
