We have several clusters where we run Caddy v.2 as a reverse proxy. Now we are making changes to move from a single Caddy node setup to a cluster setup with multiple nodes.
Planing to use s3 storage module. It is already tested and looks OK for us.
Manipulating with storage “prefix” config it is possible and safe to use same S3 bucket for different clusters.
But in the same time module documentation said that it uses single node Redis as the lock.
So the question is:
Is it safe to use same Redis instance and db for different Caddy clusters or this will cause any issues?
