Provision

What Will You Do

In this part, you will provision an Amazon EKS cluster with AWS Fargate profiles.

Update Cluster Specification

• Open a suitable YAML editor and copy/paste the example EKS cluster specification provided below.
• Save the file as "fargate-demo.yaml" (an example)

Cluster Spec Explained

In the example cluster spec provided,

• The name of the EKS cluster will be "fargate-demo" and it is configured to be provisioned in the "defaultproject" in your Org.
• The EKS cluster is configured with one managed node group (i.e. "managed") and two Fargate profiles (i.e. "fp-dev" and "fp-demo")

The following items in the declarative cluster specification will need to be updated/customized for your environment.

• cluster name: "fargate-demo"
• project: "defaultproject"
• cloud credential: "aws-cc"
• region: "us-west-2"
• AWS Tags as required in your AWS account

Provision EKS Cluster

• Type the command below to provision the EKS cluster

rctl apply -f fargate-demo.yaml

If there are no errors, you will be presented with a "Task ID" that you can use to check progress/status. Note that this step requires creation of infrastructure in your AWS account and can take ~20-30 minutes to complete.

{
  "taskset_id": "lk5opd2",
  "operations": [
    {
      "operation": "NodegroupCreation",
      "resource_name": "managed",
      "status": "PROVISION_TASK_STATUS_PENDING"
    },
    {
      "operation": "ClusterCreation",
      "resource_name": "fargate-demo",
      "status": "PROVISION_TASK_STATUS_PENDING"
    }
  ],
  "comments": "The status of the operations can be fetched using taskset_id",
  "status": "PROVISION_TASKSET_STATUS_PENDING"
}

• Navigate to the specified "project" in your Org
• Click on Infrastructure -> Clusters.

The provisioning process can take approximately 30 minutes to fully complete. Once provisioning is complete, you should see a healthy cluster in the project in your Org
