Part 2: Workload

What Will You Do

In this part of the self-paced exercise, you will deploy a Windows workload to the manged Windows node group on the EKS Cluster.


Step 1: Deploy Windows Workload

In this step, we will deploy a Windows workload into the previously created namespace.

  • Navigate to the project in your Org where the cluster is located.
  • Select Applications > Workloads
  • Click "New Workload" > "Create New Workload"
  • Enter "windows-workload" for the name
  • Select "k8s YAML" for the Package Type
  • Select "Upload files manually"
  • Select the "Windows" namespace
  • Click "Continue"

UI Workload

  • Save the below specification file to your computer as "windows-workload.yaml".

Important

The 'nodeSelector' section, lines 31 & 32, specifies which OS to use. This is an important configuration to specify to avoid scheduling issues. Without a nodeSelector configuration, this deployment could be scheduled on a Linux node, causing it to fail. Kubernetes scheduling doesn't recognize Operating System, rather it is based on scores. For more information, please visit this URL.

- Click "Choose File" to upload the previously created YAML file
- Click "Save and Go To Placement"

- Click "Publish"

The workload is now published on the cluster.

## Step 2: Validate Workload

In this step, we will verify the Windows workload is running and accessible.

- Navigate to the project in your Org where the cluster is located.
- Select Infrastructure > Clusters
- Click on the kubectl link of the cluster and type the following command 
kubectl get pods -n windows
You should see output similar to the following showing the windows workload running
NAME READY STATUS RESTARTS AGE windows-server-iis-ltsc2019-7b985676f9-wpvbn 1/1 Running 0 13m
- Enter the following command 
kubectl get services -n windows
You should see output similar to the following showing the external IP address of the workload.
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE windows-server-iis-ltsc2019-service LoadBalancer 10.100.127.47 ac1f6dd67171541c2a4e0d6818b5f9c2-954058756.us-west-2.elb.amazonaws.com 80:32376/TCP 9m24s ```

  • Enter the external IP address from the previous command into a web browser

You should see a response from the Windows web server workload.

Running Workload


Recap

Congratulations! At this point, you have successfully provisioned a Windows workload running on an Amazon EKS cluster with a managed Windows node group in your AWS account.
