AWS Elastic Kubernetes Service - Blue Green Deployment

This project will show you how to create you infrastructure using Cloudformation and Kubernetes (EKS)

---

Setting your AWS infrastructure

For deploy your infrastructure execute the next script inside cloudformation/ folder:

sh ./create.sh CloudDevOpsCapstone network_and_eks.yml network_and_eks.json

Note: The creation of EKS cluster takes almost 10 minutes

After the EKS cluster creation is success you can add EKS context in your machine with next command:

aws --region us-west-2 eks update-kubeconfig --name BlueGreen-Prod

See nodes attached to your cluster with next command:

kubectl get nodes

Blue Green deployment configuration is setting in Kubernetes using HAProxy Ingress, Deployments and Services

Enter in the folder blue-green/

1. Install HAProxy Ingress Controller

   kubectl apply -f 1_haproxy-ingress.hapee.yaml

2. Install deployment of app v1

   kubectl apply -f 2_app-v1.yaml

3. Install deployment of app v2

   kubectl apply -f 3_app-v2.yaml

4. Install blue service

   kubectl apply -f 4_blue-service.yaml

5. Install green service

   kubectl apply -f 5_green-service.yaml

6. Install ingress

   kubectl apply -f 6_ingress.yaml

7. Expose ingress controller with a load balancer service

   sh ./7_expose_url_with_load_balancer.sh

   Then you can know the EXTERNAL-IP and check the application deployed in your browser with the path /

8. Remove the infrastructure:

   sh ./destroy.sh CloudDevOpsCapstone network_and_eks.yml network_and_eks.json

Notes

• In order to do a blue-green deployments for future releases update the section to version in 4_blue-service.yaml and 5_green-service.yaml files

• You can access to the blue version by adding on the header request:

    Host: blue.deploy
  

  This header will be processed by Ingress which will be redirecting the request to blue service
