MongoDB Standalone - issue with templates

[gauravjain1582]

Folks, I observed an issue with init jobs config (for deployments relay on mongodb), specifically when mongoDB set to run in standalone architecture. k8s do not create headless service for standalone mode, hence a service/endpoint should be referred in place of headless services.

Following need some logical handing for standalone mode. until nc -z -w 2 {{ $.Release.Name }}-mongodb-headless {{ $mongodb_port }} && echo mongodb ok;

--->

until nc -z -w 2 {{ $.Release.Name }}-mongodb {{ $mongodb_port }} && echo mongodb ok;

`

{{- $mongodb_port := (int (index .Values "mongodb" "service" "port")) }}
- name: wait-for-db
  image: busybox:1.28
  command:
    - 'sh'
    - '-c'
    - >
      until nc -z -w 2 {{ $.Release.Name }}-mongodb-headless {{ $mongodb_port }} && echo mongodb ok;
        do
          echo 'Waiting for MongoDB Connection...'
          sleep 2;
      done
{{- end }}
{{- end -}}

let me know if anyone able to reproduce it.

Thanks

The relevant sections of the template are here: https://github.com/StackStorm/stackstorm-ha/blob/8388b0bb741be1f1c77ab7d942f9c0e4aae23624/templates/_helpers.tpl#L42-L55 https://github.com/StackStorm/stackstorm-ha/blob/8388b0bb741be1f1c77ab7d942f9c0e4aae23624/templates/_helpers.tpl#L89-L104

It is interesting that we handle the non -headless case in one helper but not the other. I would be happy to review a PR that improves this. Thanks!
