Setting up Cluster Orchestrator for AWS EKS clusters

To enable Cluster Orchestrator for AWS EKS clusters associated with your account, follow these two simple steps:

Step 1:: Enable feature flag​

Currently, this early access feature is behind a feature flag . Contact Harness Support to enable the feature. After it is enabled, you can see it directly in the navigation bar.

Step 2: Navigate to Cluster Orchestrator in the Cloud Costs Module​

Click on Cluster Orchestrator from the navigation bar. Once you click on it, you will be taken to the home page, where you can see all the clusters associated with your account.

For each cluster, you can see the following information:

  • Name of the cluster
  • Region of the cluster
  • Number of nodes associated with the cluster
  • CPU
  • Memory
  • Potential spend of the cluster
  • Savings realized
  • Whether the Cluster Orchestrator is enabled for the particular cluster

On this page, you can also see the total cost of the clusters and the spot savings.

Step 3: Enable the Cluster Orchestrator for a Selected Cluster​

For a given cluster, click on the enable option, which will take you to the enablement screen. To enable the Cluster Orchestrator for the particular cluster, there are two steps to complete:

Step A: Cluster Permissions​

You will be asked to run a shell script in your terminal and verify the connection. Upon successfully establishing the connection, click on the next step to configure.

Step B: Configuration​

Cluster Orchestrator allows you to choose a Base On-Demand Capacity, which can be further split into percentages to determine how much should be used by Spot and On-Demand instances. You can also choose the distribution strategy between Least-Interrupted or Cost-optimized. Once all the details are filled in, you can see the potential savings and click on the "Complete Enablement" button to enable Cluster Orchestrator for the cluster.

After the setup is complete, Cluster Orchestrator supports three screens to show information about your cluster:
