  1. Challenge

    Create a Blue/Green Setup for an Existing Deployment

    Create a blue/green Deployment setup for the existing web-frontend Deployment in the bluegreen Namespace.

    You can find a Deployment manifest for web-frontend on the CLI server at /home/cloud_user/bluegreen/web-frontend.yml. Feel free to copy this manifest in order to create your green Deployment.

    Give the green Deployment the name web-frontend-green and set the env label to green in the Pod template.

    Once you have created the green Deployment and verified that it is working, modify the web-frontend-svc Service so that it points only to the new green Deployment's Pods. This is a NodePort Service, and you can test it by reaching out to port 30081 on any of the cluster nodes, for example: curl k8s-control:30081.

  2. Challenge

    Create a Canary Setup for an Existing Deployment

    Create a canary Deployment setup for the existing auth Deployment in the canary Namespace.

    There is a manifest file for the existing Deployment at /home/cloud_user/canary/auth.yml. You can copy this file to create your canary Deployment.

    Give the canary Deployment the name auth-canary, and set the env label in the Pod template to canary.

    There is a Service called auth-svc, also in the canary Namespace. Modify this Service to direct traffic to both the main and canary Deployments. Configure your setup so that there will be 4 total replicas, including both the main Deployment and the canary Deployment, and so that approximately 25% of traffic will go to the canary Pod(s). Note that you may need to modify the original main Deployment in order to accomplish this.

    The Service is a NodePort Service, and you can test it by reaching out to port 30082 on any of the cluster nodes, for example: curl k8s-control:30082.
