kbrew as cluster bootstrapper #126
Description
Currently, kbrew is being used as a client-side CLI tool, but can it be extended to a cluster component(as a Pod) which could be created as soon as the cluster is created with a configuration file that should contain some must-have applications to be deployed on the cluster? This is something similar to the Bootstrapper script in EC2 instances which gets executed as soon as the instance is launched.
This way a complete flow of a cluster creation + adding default applications/recipes (example: Ingress controller, OPA Gatekeeper, Argo, or a Custom application recipe) can be automated with probably just a single command (considering terraform apply creates the cluster and install kbrew bootstrapper pod and then kbrew bootstrapper taking care of rest of the installations).
Using Git: The kbrew bootstrapper fetches the list of the recipes from a remote git repo and keeps the recipes list in sync with the deployed recipes.
