This is minimal setup needed to have Capact Gateway and Hub working properly. We won't run Actions, so I don't install Argo, kubed, etc.

UPDATE: Unfortunately due to the following error:

 • Installing capact Helm chart
Error: while installing Helm chart [capact]: Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": Post "https://ingress-nginx-controller-admission.capact-system.svc:443/networking/v1beta1/ingresses?timeout=10s": dial tcp 10.96.185.212:443: connect: connection refused

And inability to change the component installation order without modifying CLI, I needed to abandon the idea and install all components except monitoring. In cluster dump I saw the ingress controller pod is not ready. I would need to investigate this issue further (if we properly wait for the ingress controller), but unfortunately I ran out of time.
