Why can't I do X in Starlark?

Starlark is intended to be a configuration and orchestration language, not a general-purpose programming language. It is excellent at simplicity, readability, and determinism, and terrible at general-purpose programming. We want to use Starlark for what it's good at, while making it easy for you to call down to whatever general-purpose programming you need for more complex logic.

Therefore, Kurtosis provides:

• plan.run_sh for running Bash tasks on a disposable container
• plan.run_python for running Python tasks on a disposable container
• plan.exec for running Bash on a service

All of these let you customize the image to run on, so you can functionally call any code in any language using Kurtosis.

What is Kurtosis building next?

Great question, check out our roadmap page for the latest details on where we plan to take Kurtosis next.
