Custom Warehouses

[han-steve]

Hi, I've been playing around with Kargo for deploying k8s infra and ML model servers, and it's great!

I have 2 quick questions about the customizability of Kargo. For ML model servers, we save the model weights on S3 with a version number, and I'd like to create a Freight whenever there is a folder with a new version uploaded. Is it possible to create custom Warehouse for this use case?

Another question is about custom code in promotion step. For example, some of our production clusters take a slightly different yaml for the model server spec, and we need to write some custom code to transform the master yaml to the target yaml on the specific branches. Can I accomplish this using an http step?
