This PS moves all the config files to be directly values driven, both simplifying over-ride and allowing configs to be targeted to pods in future work. Change-Id: I7e16585c9ef49275327d19a48f00bad192dc4923

This function renders out configuration sections into a format suitable for
|
|
incorporation into a config-map. This allows various forms of input to be
|
|
rendered out as appropriate, as illustrated in the following example:
|
|
|
|
With the input:
|
|
|
|
conf:
|
|
some:
|
|
config_to_render: |
|
|
#We can use all of gotpl here: eg macros, ranges etc.
|
|
Listen 0.0.0.0:{{ tuple "dashboard" "internal" "web" . | include "helm-toolkit.endpoints.endpoint_port_lookup" }}
|
|
config_to_complete:
|
|
#here we can fill out params, but things need to be valid yaml as input
|
|
'{{ .Release.Name }}': '{{ printf "%s-%s" .Release.Namespace "namespace" }}'
|
|
static_config:
|
|
#this is just passed though as yaml to the configmap
|
|
foo: bar
|
|
|
|
And the template:
|
|
|
|
{{- $envAll := . }}
|
|
---
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
metadata:
|
|
name: application-etc
|
|
data:
|
|
{{- include "helm-toolkit.snippets.values_template_renderer" (dict "envAll" $envAll "template" .Values.conf.some.config_to_render "key" "config_to_render.conf") | indent 2 }}
|
|
{{- include "helm-toolkit.snippets.values_template_renderer" (dict "envAll" $envAll "template" .Values.conf.some.config_to_complete "key" "config_to_complete.yaml") | indent 2 }}
|
|
{{- include "helm-toolkit.snippets.values_template_renderer" (dict "envAll" $envAll "template" .Values.conf.some.static_config "key" "static_config.yaml") | indent 2 }}
|
|
|
|
The rendered output will match:
|
|
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
metadata:
|
|
name: application-etc
|
|
data:
|
|
config_to_render.conf: |
|
|
#We can use all of gotpl here: eg macros, ranges etc.
