This document summarizes an open house event on DevOps hosted by Prashant P Beniwal. The agenda includes introductions, an overview of DevOps, and Kubernetes. Prashant then demonstrates deploying and managing an application on Google Kubernetes Engine (GKE), including building and pushing a Docker image, creating a Kubernetes cluster, deploying the application, exposing it via a load balancer, scaling the deployment, and rolling out a new version. The document also provides information about Prashant's experience and the Certified Professional DevOps Foundation certification.

8. Running your application
on GKE

9. About GKE
• Google Kubernetes Engine is a managed, production-ready environment for
deploying containerized applications
• Kubernetes Engine allows you to get up and running with Kubernetes in no
time, by completely eliminating the need to install, manage, and operate
your own Kubernetes clusters.
• Managed Kubernetes Engine feature allows you to handle increased user
demand for your services, keeping them available when it matters most

10. Kubernetes Deployment:

11. Kubernetes Service:

12. 1. Package your app into a Docker image
2. Upload the image to a registry
3. Create a Kubernetes cluster
4. Deploy your app to the cluster
5. Expose your app to the Internet
6. Deploy a new version of your app
To package and deploy your application on GKE:

13. Flow of Demo on GKE:
Load BalancerChrome
External Load balancer Service
Deployment
Replica Set
POD
Container
Control Node
Worker Node

14. Step 1 - 2

15. Build Push
Create Docker Image and Push
>> docker build -t pbeniwal/helloworld:v1 .
>> docker push pbeniwal/helloworld:v2

16. 3 – Create Cluster
Create a container cluster
https://console.cloud.google.com/

17. kubectl create deploy helloworld --image=pbeniwal/helloworld:v1 --port=8080 –replicas=2
Step 4 – Create Deployment – Imperative
Check status of Deployment, ReplicaSet and POD

18. kubectl expose deployment helloworld --type LoadBalancer --port 80 --target-port 8080
Step 5 – Expose Application
Check External IP assigned to External Load balance service
External IP will be assigned shortly by GKE

19. Access Application

20. 6. Deploy a new version of your app

21. New image pushed to docker hub
>> docker build -t pbeniwal/helloworld:v2 .
>> docker push pbeniwal/helloworld:v2

22. kubectl scale deployment helloworld --replicas=4
Scaling Up Deployment
Check status of deployments and Replicaset

23. kubectl set image deployment/helloworld helloworld=pbeniwal/helloworld:v2 --record
Updating Deployment
kubectl rollout status deployment helloworld -w
