Encoding a template

[cschmatzler]

Hi!

I am trying to use gomplate for Kubernetes secrets, and as such need to encode values.
For one of my deployments, I need a secrets file mounted, which means I have the file as a template which then needs to be encoded.

So far, I've tried

apiVersion: v1
kind: Secret
metadata:
  name: synapse-config
  namespace: medium-place
data:
  config.yaml: {{ base64.Encode template "config" . }}
  
{{ define "config" }}
  server_name: {{ .Env.SERVER_NAME }}
  db_pass: {{ .Env.DB_PASS }}
  ....
{{ end }}

which results in a unexpected <template> in parenthesized pipeline.
Using the pipe syntax instead, template "config" . | base64.Encode, it encodes the dot as a string and passes that as parameter to the template instead of rendering the template and then encoding it.
Adding parenthesis doesn't seem to work.

Is there any way to accomplish this?
Cheers

The template action is a bit odd in that it doesn't behave like regular template functions. As an alternative, there's tmpl.Exec, which should do what you want.

That does indeed work, I didn't scroll down far enough. Thank you so much for your quick answer!
