Part 2: Provision

What Will You Do

In this part of the self-paced exercise, you will provision an Amazon EKS cluster based on a declarative cluster specification using the default blueprint. This EKS cluster will be used to manage the pipeline.

---

Step 1: Cluster Spec

• Open Terminal (on macOS/Linux) or Command Prompt (Windows) and navigate to the folder where you cloned the Git repository
• Navigate to the folder "/getstarted/eks-gitops/cluster"

The "cluster.yaml" file contains the declarative specification for our Amazon EKS Cluster.

The following items may need to be updated/customized if you made changes to these or used alternate names.

• project: "defaultproject"
• cloudprovider: "aws-cloud-credential"

kind: Cluster
metadata:
  name: gitops-eks-cluster
  project: defaultproject
spec:
  blueprint: default
  cloudprovider: aws-cloud-credential
  clusterConfig: null
  cniprovider: aws-cni
  proxyconfig: {}
  type: eks

apiVersion: rafay.io/v1alpha5
availabilityZones:
- us-west-2a
- us-west-2b
kind: ClusterConfig

  name: gitops-eks-cluster
  region: us-west-2
  version: "1.20"

  minSize: 1

  privateNetworking: true
  volumeSize: 80
  volumeType: gp3

  cidr: 192.168.0.0/16
  clusterEndpoints:
    privateAccess: true
    publicAccess: true
  nat:
    gateway: Single

Step 2: Provision Cluster

• Type the command below to provision the EKS cluster

rctl apply -f cluster.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.

Cluster: gitops-eks-cluster
{
  "taskset_id": "pk0xz7k",
  "operations": [
    {
      "operation": "NodegroupCreation",
      "resource_name": "managed-ng1",
      "status": "PROVISION_TASK_STATUS_PENDING"
    },
    {
      "operation": "ClusterCreation",
      "resource_name": "gitops-eks-cluster",
      "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 "defaultproject" project in your Org
• Click on Infrastructure -> Clusters. You should see something like the following

• Click on the cluster name to monitor progress

---

Step 3: Verify Cluster

Once provisioning is complete, you should see the cluster in the web console

• Click on the kubectl link and type the following command

kubectl get nodes

You should see something like the following

NAME                                           STATUS   ROLES    AGE   VERSION
ip-192-168-98-104.us-west-2.compute.internal   Ready    <none>   14m   v1.20.11-eks-f17b81

---

Recap

Congratulations! At this point, you have successfully provisioned an Amazon EKS cluster with the default blueprint in your AWS account using the RCTL CLI.
