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"
- cloudCredentials: "aws-cloud-credential"
apiVersion: infra.k8smgmt.io/v3
kind: Cluster
metadata:
name: gitops-eks-cluster
project: defaultproject
spec:
blueprintConfig:
name: default
version: latest
cloudCredentials: aws-cloud-credential
config:
availabilityZones:
- us-west-2a
- us-west-2b
addons:
- name: kube-proxy

- name: vpc-cni

- name: coredns

clusterEndpoints:

publicAccess: true
cidr: 192.168.0.0/16

gateway: Single
type: aws-eks
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.
