argocd-templatize

Templatize finds ./*.json and ./*.yaml and passes them through text/template with the environment variables named TPZ_*.

TPZ_SOME_THING is available as {{.SomeThing}} in the template.

Its intended usage is as a custom plugin for argocd, to be able to use cluster specific variables in your YAML.

You can install this into ArgoCD with the following Kustomization: https://github.com/Jille/argocd-templatize/blob/master/kustomization.yaml

Now you can enable templatize in your Application:

 apiVersion: argoproj.io/v1alpha1
 kind: Application
 spec:
   project: default
   source:
     repoURL: ssh://git@github.com:/Jille/configuration.git
+    plugin:
+      name: templatize
+      env:
+      - name: TPZ_CLUSTER
+        value: prod

TPZ_CLUSTER will now be available as {{.Cluster}} in your YAML. You can use all functionality of text/template.
