Sure! If you’re dealing with multiple apps in a monorepo on Render and need different Ruby versions, it can be tricky because Render picks up the Ruby version from a single .ruby-version file in the root of your repo. Here are some ways to handle it:
- Use Docker: Create Dockerfiles for each app with the desired Ruby version specified. Render supports deploying Docker containers, giving you control over the environment.
- Environment Variables/Configuration: Set up each app to read the required Ruby version from environment variables or configuration files. Adjust the app’s behavior based on this information.
- Feature Request: Request Render to add native support for specifying Ruby versions, similar to how they support Node.js versions.

I hope this will help you.
