How to run builder playground with custom recepies?

[dvush]

I would like to be able to add more things to the playground without adding it to the builder playground repo.

For example, add databases, custom closed-source services built from private repos, etc.

Builder playground gives a nice API to connect things with each other so when docker compose is run everything is already set up.

Currently, I am thinking of this approach:

• user creates a golang project that depends on the builder-playground
• user adds implementation of their custom services to the project
• user creates a recipe made from services defined both in builder-playground and their repo
• this recipe is then injected into the standard implementation of the builder-playground CLI
• when project is built it will output builder-playground binary with all the tools that are available upstream plus this new recipe

Here is an example implementation that works as explained here #308

I want to hear opinions on this approach.

Interesting, and thanks for writing this up!

I'm thinking what about non-Golang projects, like something written in Rust that wants to use playground for a custom testing setup. Would we still recommend to define custom services in Golang? Do we even need a full language for it, or would pure configuration like YAML also work?
