[Feature]: Support for redis sentinel

[onedr0p]

Feature detail

Hi 👋🏼

It would be great if immich could connect to a highly available redis instance.

Here's a couple examples of applications that support this method of redis.

• https://www.authelia.com/configuration/session/redis/
• https://github.com/outline/outline/blob/93bb9d067d0f61a2f5d6f1d302774b128095a4d0/.env.sample#L22L29

Thanks!

Hello,

Thank you for opening the issue. This will be left to the user to implement because it is very specific to a user group

To be able to implement sentinel support, there would have to be a switch from node-redis to ioredis, since node-redis doesn't have sentinel support redis/node-redis#302 :/

Would you accept PRs on this change?

[alextran1502]

You can try but I think there might be dependencies that depends on node-redis, like the socket-io implementation

[onedr0p]

Actually it looks like Bull passes the RedisOpts directly to ioredis, not sure why the redis lib is in the packages.json

Since with Redis Sentinel would require multiple hosts passthru to the application, do you think the way Outline made it configurable is a decent decision for implentation?

Here is the reason we have Redis in the dependency https://docs.nestjs.com/websockets/adapter

@alextran1502 Could you re-open this so it would get closed when the support is implemented from the PR?
