-What is Deployment in k8s?
A Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. Deployments can help to efficiently scale the number of replica pods, enable the rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary.
A Deployment provides a configuration for updates for Pods and ReplicaSets.

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

apply the deployment to your k8s (minikube) cluster by command
kubectl apply -f deployment.yml-Make sure you have a Kubernetes cluster set up, either locally or on a cloud provider.
