The HyScale specification looks familiar to most developers/devops who have been doing development or deployment for some years as we wanted to create a spec that is intuitively understood and application-centric, while at the same time grows to support 80% of the use-cases out there. The spec is meant to also support K8s native elements such as sidecars, ingress, etc. We are also looking at the compose-spec to see if there is some convergence in the near/late future.
The HyScale spec schema itself is available at the companion repo here: https://github.com/hyscale/hspec
