How are multiple instances of Hasura GraphQL Engine and Postgres run locally via Docker?

Question

The docker-compose.yaml to spin up Hasura + Postgres locally, have commands to start a single instance of both. How can multiple instances (say, for multiple projects) be setup locally?

Answer 1

The source docker-compose.yaml file needs to be modified to include multiple volumes of Postgresql and Hasura GraphQL Engine, in addition to allocating ports for them. This is a good example of how it is done.
