background information​

customer specific parameters​

In bootstrap/customer-config.yaml the customer specific parameters are set, which are then used for rendering the chart values files.

Rendering values templates​

To create values files for specific instances in an automated way we render the values files with the template renderer gomplate

Source: https://github.com/hairyhenderson/gomplate Docs: https://docs.gomplate.ca/

The command to render all values templates ending with '.yaml.tmpl' and write the result in the corresponding '.yaml' in the same directory:

bootstrap/bootstrap.sh

The used variables for the templates are defined in bootstrap/customer-config.yaml and are stored in the context kubriX.

Example​

Content of the bootstrap/customer-config.yaml is

domain: demo.kubrix.cloud

A values-demo.yaml.tmpl with the content

hostname: foo.{{ kubriX.domain }}

will then result in a values-demo.yaml with the content

hostname: foo.demo.kubrix.cloud

Escaping helm brackets​

When you want to use brackets {{ }} also in your values files (when using variables in values files which should not get rendered by gomplate, then you need to escape them like this:

hostname: foo.{{`{{ .Values.global.bla }}`}}

then the output will be

hostname: foo.{{ .Values.global.bla }}

This is the same syntax as in argocd applicationsets in helm templates.
