  1. Challenge

    Convert the Service Manifest into a Service Template in a New Helm Chart

    Create a folder for the new chart and name it blog. Create the minimum necessary scaffolding for the new chart. Locate the existing manifest for the service in the /home/cloud_user/kubernetes directory. Copy the service.yaml file into the new charts template directory. Take the necessary values from the service.yaml file and create entries in the values.yaml file. Create the necessary directives to set the values in the service.yaml template. Make sure the service type is NodePort and the nodePort value is 30080.

  2. Challenge

    Convert the Application Manifest into a Deployment Template in a New Helm Chart

    Locate the existing manifest for the application in the /home/cloud_user/kubernetes directory. Copy the application.yaml file into the new charts template directory and name it deployment.yaml. Take the necessary values from the deployment.yaml file and create entries in values.yaml. Create the necessary directives to set the values in the service.yaml template.

  3. Challenge

    Ensure the Manifests Render Correctly and Deploy the Application as a NodePort Application

    Use the --dry-run option of the install command to review the manifests and ensure they render correctly. After they are verified, deploy the application, then access the application on the primary server's public IP address at the node port.
