🚀Day 32 - Launching your Kubernetes Cluster with Deployment

✅What is Deployment in k8s

A Deployment provides a configuration for updates for Pods and ReplicaSets.

You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new replicas for scaling, or to remove existing Deployments and adopt all their resources with new Deployments.

✅Task-1:

Create one Deployment file to deploy a sample todo-app on K8s using the "Auto-healing" and "Auto-Scaling" features

  • add a deployment.yml file
apiVersion: apps/v1
kind: Deployment
metadata:
  name: node-app-deployment
  labels:
    app: node-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: node-app
  template:
    metadata:
      labels:
        app: node-app
    spec:
      containers:
        - name : node-todo-app
          image: sarikak/node-app-batch-6
          ports:
            - containerPort: 8000
  • apply the deployment to your k8s (minikube) cluster by command kubectl apply -f deployment.yml
