kubriX Flavor Templates

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.
