We are using FunWithFlagsUI to check the flags we have on our Redis instance. Since Redis has several DBs one can choose from, this raises a problem - we need to tell the UI which Redis DB to use.
After reading the docs, I couldn't find any option to do that. By default, the UI will always read from Redis DB 1, which is not where our flags are.
Is there a way to tell the UI which Redis DB to use?
It's not very clear to me what do you mean by the UI, but it seems you can configure redis database on the config adding a database option:
config :fun_with_flags, :redis, database: 1
