Is there any automated way to convert this yaml into helm charts
.
Or any other workaround or sample template that I can use to achieve this.
Even if there is no any generic way, then I would like to know how to convert this specific yaml into helm chart.
Also want to know what all things should I keep configurable (I mean convert into variables) as I can't just put these resource in yaml into separate template folder and called it helm chart.
At heart a Helm chart is still just YAML so to make that a chart, just drop that file under templates/ and add a Chart.yml.
