keda-goclient

An application functioning as a REST API that does the following:

• Uses client-go to interface with Kubernetes. This has been developed in wsl2 with a local Docker enabled Kubernetes single node cluster
• Acts as a client to create KEDA ScaledJobs and ScaledObjects. In this repo, it was specifically for creating GitHub Action runners.
• scaler-kubernetes-webhook .yamls can be deployed to set up both Mutating and Admission Webhooks that will be invoked during KEDA resource creation. The logic currently is that a metadata.label of either scaledjob or scaledobject will be adding during resource creation by the Mutating webhook

Below is the request body structure that some of these endpoints accept. POST bodies should follow the same general structure that a Kubernetes or KEDA .yaml expects
