Kubernetes is capable of automatically creating dependent compute resources, including storage volumes, before starting your applications.

Services get the same treatment. Deployments and Services are decoupled by design. One service can target multiple deployments.

When you define a Kubernetes service a lot needs to happen, but most of it can be done asynchronously. This is where control loops come in.

Control loops go beyond initial provisioning and provide active management of resources. Your desired state is enforced continuously.

But it goes deeper than that. In many cases the control loops must work with other parts of the Kubernetes system to get things right.

Deployments and Services don't paint the whole picture. Initializers can modify desired state based on policy.https://kubernetes.io/docs/admin/extensible-admission-controllers/ …

I'm not saying using Terraform to generate Kubernetes configs is a bad thing. Almost anything is an improvement over managing YAML files.

Read this in its entirety earlier tonight, and I really like what you lay out. Definitely addresses the problems I have as a heavy Helm user

I agree with a lot but I'm not quite sold on the strawman for "overlays"

Overlays share many foundations with kubectl apply, controllers, and other existing mechanisms, but I agree we need to try on real examples.
