Incorrect redis server naming in example docker-compose triggers Redis NOAUTH error about immich HOT 4 OPEN

We can solve this right before going stable to avoid making unnecessary breaking changes to others setup now

Proposed solution here - #11378

So, most instances of docker will resolve either the container name, hostname, or service name (which is redis) to the container.

With that said, I've felt that we should fix this issue before we go to stable. I would propose something different than your PR, though. I've seen a lot of people have this issue come up.

I honestly think we should specify the service name, container name, and hostname for every service to all be identical. Something like immich-server, immich-redis, immich-postgres. (you can't use _ in hostnames). At the same time we could add those as the hostnames to the default env file, and it shouldn't break old installs. Whether this will actually happen is a big question.

Example:

services:
  immich-server:
    container_name: immich-server
    hostname: immich-server
    image: ...

Yeah these are all inelegant options. I have a legacy container named redis and this is what tripped me up. The correct way is indeed immich-redis style naming I agree. Your proposal makes the most sense but will lead to some breaking changes I suppose.
