Experiment: Cluster bootstrapping using ArgoCD ApplicationSet and git:file generator

Assumption: Repo contains necessary charts and valuefiles, or valuefiles for charts in public Helm repos, or manifests. Supposedly resonable for the cluster tooling repo.

Cons:

• configs in each directory
• each config contains links to this repository
• configs resemble application manifest too much
• Still ended up with helm-style go-templating

Pros:

• less copy pasting due to the reusage of fields equal to the basepath

NOTE:
