Hi, thank you very much for your interest in this project and your willingness to contribute your improvements. I have a few questions that are not yet clear to me:

Why adopt Kubernetes/Kodo? Does it have potential advantages in performance/availability compared to Docker?
When using Kubernetes, is a different image from Docker required? Is this image publicly available? Is it consistent with the environment declared in utils.constants?

[samaritan1998]

Sorry, I’m still working on the update. The goal is to make it compatible with both starting Docker containers and creating Kubernetes pods via HTTP requests through Kodo.

Sounds great!

I've also been wanting to support multiple sandbox backends, and am planning to add a native macOS sandbox option to minimize the base runtime overhead.

I'll convert this to a draft for now

Feel free to @ me when it's ready
