Congrats on this launch, it's great to see serious efforts at Kubernetes simplification and I hope you succeed! K8s bills itself as a "platform for platforms", and such projects are a real test of that idea. Questions: 1. How do you deal with the mutability of K8s resources? Do you assume people won't change the underlying resources that you generate, or do you keep k8s controllers running to ensure there's no deviation? 2. How understandable is your generated output to humans? Do users have a way to go "backwards" through your abstraction? (Since your tool lives in an ecosystem with many other kubernetes tools, your users will sometimes end up having to deal with the generated output, since other tools operate at the K8s level such as prometheus, log aggregators etc) 3. Do you interoperate with K8s-level resources well? Do _all_ my services need to be in this abstraction for this to work well? e.g. Can my hyscale yaml reference a non-hyscale service for any reason? Or are they essentially two separate worlds? |

Answers to your Questions:
1. The expectation is that people deploying through hyscale don’t want to go and modify K8s resources directly on the cluster behind the scenes. If they do, then it either deviates from the hspec files in git or they have parallel K8s yamls which won’t make much sense either. As of now, hyscale deploys and doesn’t keep anything (eg. controller) running, But it's a good suggestion to keep the K8s resources in sync with the desired state (hspec) and we’ll certainly put some thought into it.
2. HyScale outputs standard K8s manifest yamls which are as readable as any well hand-coded. On the other hand, if there was a way to generate back hspec files from existing K8s yamls, would that be interesting/useful?
3. Suppose you have K8s resources/snippets already written for some of your services, you can refer to them in hspec and add application context to it and make use of profiles for environment variations. If the question is more about off-the-shelf services (eg postgres, redis, etc), we have helm chart support coming up. https://github.com/hyscale/hyscale/wiki/Roadmap#2-ots-off-th...
