Have you worked with Helm charts — have you edited templates?

Yes, I have worked with Helm charts and edited templates. Helm templates typically use Go templates for dynamic generation of Kubernetes manifests. For example, resource names, replica counts, container settings, etc., can be parameterized. Here's a simple example of a Deployment template:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}-app
spec:
  replicas: {{ .Values.replicaCount }}
  template:
    spec:
      containers:
        - name: app
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}

Editing templates allows customization of charts for specific requirements and automates deployment.
