DEMO STEPS:
***************
Step 1: Access & Inspect the Kubernetes Cluster
------------------------------------------------------------------------------
$ kubectl cluster-info
$ kubectl get nodes
$ kubectl get pods -n kube-system
Step 2: Create a Deployment Manifest (kubectl commands)
----------------------------------------------------------------------------------------------
$ kubectl create deployment frontend --image=nginx:1.20.0 --replicas=1 --dry-run=client -o yaml
Copy the output content and create a file frontend.yaml
Step 3: Deploy & Inspect the Deployment Rollout
------------------------------------------------------------------------------
$ kubectl apply -f frontend.yaml
$ kubectl rollout history deployment frontend
$ kubectl rollout status deployment frontend
Step 4: Scale the Deployment (Replica=2)
-------------------------------------------------------------------
Either you can edit the resource itself using kubectl commands
Or you can modify the manifest yaml file and apply the same (Recommended)
Step 5: Update the Image to another Version & Inspect the Deployment
-------------------------------------------------------------------------------------------------------------------
Either you can edit the resource itself using kubectl commands
Or you can modify the manifest yaml file and apply the same (Recommended)
Step 6: Rollback to a Previous Revision
----------------------------------------------------------------
$ kubectl rollout history deployment frontend --revision=2
$ kubectl rollout history deployment frontend --revision=1
$ kubectl rollout undo deployment frontend
Step 7: Pause a rollout and make some Updates to the Pod template
----------------------------------------------------------------------------------------------------------------
$ kubectl rollout pause deployment frontend
$ kubectl set image deployment frontend nginx=nginx:1.20.2
Step 8: Resume the Deployment
-----------------------------------------------------
$ kubectl rollout resume deployment frontend
