A Minimal Deployment Template

Turning a static manifest into a chart template.

From Static Manifest to Template

A chart is just a folder of templates. Each template is a Kubernetes manifest with placeholders Helm fills in at install time.

Before adding any magic, write the manifest you already know. Here is a hard-coded Deployment running one nginx pod.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
