Hello, I'm wondering if it's possible to have one Elasticsearch instance running with multiple Ruby on Rails apps, and if so, are there any instructions I can follow to make such a setup?

Thanks!

There's no reason you cannot, just use multiple indices with aliases.

Having a naming convention across your apps can help. I use {env}-{appname}-{indexname}-{version}. So my entertainment RoR app on my local development environment might have and index for movies named `development-entertainment-movies-v1` with an alias called `development-entertainment-movies` that the application code uses for reads/writes.
