Day 32 Task: 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.

Today's task let's keep it very simple.

Task-1:

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

Use this command to execute deployment.yaml file

kubectl apply -f deployment.yaml

Step 3: To verify that the deployment is running correctly, use the following command to get the status of the deployment:

kubectl get deployment

Step 4: Check the status of the pods created by the deployment using the following command:

kubectl get pods
