  * <3> reference where base and all the components are founded by fluxcd
  * <4> use of base-helm chart for fluxcd to bundle the different infra-components together
  * <5> use my default commons values for flux-chart components
  * <6> use my default to setup all commons for infra and infra components
  * <7> setup default domain (where subdomains are generate for the different components)
  * <8> overwrite componets values (here setup default also certmanager email for Let's Encrypt and setup prometheus-blackbox-exporter)
