Do you have experience creating or editing Helm manifests?

Yes, I have experience creating and editing Helm manifests. Helm is a package manager for Kubernetes that uses YAML template files to describe cluster resources.

When working with Helm manifests, I create a Chart that contains resource templates (Deployment, Service, ConfigMap, etc.) and a values.yaml file for parameterization. This makes it easy to configure and deploy applications across different environments.

An example of a simple Deployment template in Helm:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}-app
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app: {{ .Release.Name }}
  template:
    metadata:
      labels:
        app: {{ .Release.Name }}
    spec:
      containers:
      - name: app-container
        image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
        ports:
        - containerPort: 80

Thus, I can change parameters in values.yaml without editing templates, which simplifies configuration management.
