One setup that I use I have multiple discourse containers running behind a reverse proxy on a single server. For a time, I was using

```
DISCOURSE_REDIS_DB: x

```

to allow multiple Discourse servers to use a single redis server. Largely because I am lazy and don’t like keeping careful track of which server is using which number, I wanted to increase the number of redis DBs in redis to more than 16. When I asked about such, the answer I got suggested that it is a _very bad idea_ to use `redis_db` to have multiple sites on a single redis. And since then I have reconfigured things to spin up a separate redis for each site (which makes them easier to keep up with since I can use a name for them).

But this seems a little silly. And now that I’m looking, I see this:

So, I was wondering if it’s OK to use `redis_db` or whether each Discourse needs its own redis.
