- 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 Ref: https://cloud.google.co m/kubernetes-engine/
- 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
- 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
