EKS Distro kOps Cluster

Follow these instructions to create an EKS-D Kubernetes cluster using kOps. Refer to the kops documentation for full instructions. Most of these commands require that you have KOPS_STATE_STORE and KOPS_CLUSTER_NAME set and exported.

kOps Cluster Create

1. Clone the eks-distro Repository

The easiest way to access our sample kOps scripts would be to clone the repository and cd to the kops directory:

1
2
git clone https://github.com/aws/eks-distro.git
cd eks-distro/development/kops 

2. Create the Cluster Configuration

You will need to set and export KOPS_STATE_STORE to the s3 bucket to use for your kOps state and KOPS_CLUSTER_NAME to a valid subdomain controlled by Route53. You can optionally set the environment variables below to use pre-created IAM instance profile roles for your cluster instead of having kOps create them.

1
2
export CONTROL_PLANE_INSTANCE_PROFILE=arn:aws:iam::111122223333:instance-profile/kops-control-plane-role
export NODE_INSTANCE_PROFILE=arn:aws:iam::111122223333:instance-profile/kops-node-role

If your kOps state store does not exist, this script will create it. It will also generate the cluster configuration:

1
2
3
4
5
export KOPS_STATE_STORE=s3://kops-state-store
export KOPS_CLUSTER_NAME=clustername.example.com
./install_requirements.sh
./create_values_yaml.sh
./create_configuration.sh 

3. Create the Cluster

Once the cluster configuration has been created successfully, create the EKS-D cluster:

1
./create_cluster.sh 

4. Wait for the Cluster

It may take a while for the cluster. You can use the cluster_wait.sh script to wait for the cluster to be ready. Once the cluster is ready, this script will add the AWS IAM authenticator.

1
./cluster_wait.sh

When the script completes, your cluster is ready to use.

Verify Your Cluster is Running EKS-D

You can verify the pods in your cluster are using the EKS Distro images by running the following command:

1
kubectl get po --all-namespaces -o json | jq -r '.items[].spec.containers[].image' | sort -u

kOps Cluster Delete

To tear down the cluster, run:

1
./delete_cluster.sh
