Yes, you can use the single postgres for multiple Discourse sites, but unless you’re going to use multisite (see [Multisite configuration with Docker](https://meta.discourse.org/t/multisite-configuration-with-docker/14084)), each needs its own redis.

You’d need to create another database, and configure the second web container to use that one instead o fth eone named Discourse.
