By default Pulp requires Redis
Ticket moved to GitHub: "pulp/pulpcore/2057":https://github.com/pulp/pulpcore/issues/2057
Right now Pulp attempts to use Redis no matter what. Yet at the same time we don't provide the necessary settings to do so: https://github.com/pulp/pulpcore/blob/master/pulpcore/app/settings.py#L200-L207
This means that you have to configured Redis to use Pulp, yet Pulp could be fully usable (although slower) without Redis. I believe the installer configured Redis by default, but other deployments like Pulp on k8s would have to take additional care to deploy Redis, which makes Pulp harder to deploy overall. It would be better if Pulp by default didn't require Redis, yet those users who use the installer just get Redis automatically configured as a bonus.
