Do not rely on controller storage #261

Open sed-i opened 12 months ago

sed-i commented 12 months ago

Enhancement Proposal

We need to drop use_juju_for_storage=True because controller storage is deprecated.

Need to figure out how to go about dashboards and sources relations on upgrade-charm.

We need to find a solution for dashboard and sources; we should probably store those in a PVC, but how do we do that?

The only other alternative would be a peer relation, but (other than being a hacky solution) we would probably hit size limitations when storing all the dashboards.
