HELM CHART

Helm charts provide a convenient and standardized way to define,package, and deploy Kubernetes applications. They enhance the portability, manageability, and scalability of applications in a Kubernetes environment.

1. Create the sample-value.yaml file that containers key values to be used inside kubernetes resources YAML File.

# Default values for the Helm chart
image:
  repository: my-app-image
  tag: latest
replicas: 3
ephemeralStorageLimit: "1Gi"

2. Create the Kubernetes Resource -Deployment YAML file.

templates/web-deployment.yaml

In this web-deployment.yaml template, we are using the Helm templating syntax to access the values defined in the sample-values.yaml file.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}-web-app
spec:
  replicas: {{ .Values.replicas }}
  selector:
    matchLabels:
      app: web-app
  template:
    metadata:
      labels:
        app: web-app
    spec:
      containers:
        - name: web-container
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
          resources:
            limits:
              ephemeral-storage: {{ .Values.ephemeralStorageLimit }}
