Usage
My base-values/infra.yaml
use for the different components extra namespaces.

are not versioned, see Base.Example usage

- <1> namespace where install all the components later
- <2> secret to bypass secure values into the infra-components (masterPassword)
- <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)
