Create an EKS Cluster from the CLI
![](../../__attachments/89360826/Enterprise_50%25.png?inst-v=fbc98f0a-f9ae-4d4c-828f-dc0defe966ca)
Ensure that the KUBECONFIG
environment variable is set to the self-managed cluster by running export KUBECONFIG={SELF_MANAGED_AWS_CLUSTER}.conf
Create a New EKS Kubernetes Cluster
By default, the control-plane Nodes will be created in 3 different Availability Zones. However, the default worker Nodes will reside in a single zone. You may create additional node pools in other Availability Zones with the dkp create nodepool
command.
Follow these steps:
Set the environment variable to the name you assigned this cluster.
BASHexport CLUSTER_NAME=eks-example
See EKS Quick Start for information on naming your cluster.
Make sure your AWS credentials are up-to-date. Refresh the credentials command is only necessary if you are using Static Credentials (Access Keys) otherwise, if you are using role-based authentication on a bastion host, proceed to step 3:
BASHdkp update bootstrap credentials aws
Create the cluster:
NONEdkp create cluster eks --cluster-name=${CLUSTER_NAME} --additional-tags=owner=$(whoami)
BASHGenerating cluster resources cluster.cluster.x-k8s.io/eks-example created awsmanagedcontrolplane.controlplane.cluster.x-k8s.io/eks-example-control-plane created machinedeployment.cluster.x-k8s.io/eks-example-md-0 created awsmachinetemplate.infrastructure.cluster.x-k8s.io/eks-example-md-0 created eksconfigtemplate.bootstrap.cluster.x-k8s.io/eks-example-md-0 created clusterresourceset.addons.cluster.x-k8s.io/calico-cni-installation-eks-example created configmap/calico-cni-installation-eks-example created configmap/tigera-operator-eks-example created clusterresourceset.addons.cluster.x-k8s.io/cluster-autoscaler-eks-example created configmap/cluster-autoscaler-eks-example created clusterresourceset.addons.cluster.x-k8s.io/node-feature-discovery-eks-example created configmap/node-feature-discovery-eks-example created clusterresourceset.addons.cluster.x-k8s.io/nvidia-feature-discovery-eks-example created configmap/nvidia-feature-discovery-eks-example created
Inspect or edit the cluster objects:
Use your favorite editor.
NOTE: Editing the cluster objects requires some understanding of Cluster API. Edits can prevent the cluster from deploying successfully.
The objects are Custom Resources defined by Cluster API components, and they belong in three different categories:
Cluster
A Cluster object has references to the infrastructure-specific and control plane objects. Because this is an AWS cluster, there is an AWSCluster object that describes the infrastructure-specific cluster properties. Here, this means the AWS region, the VPC ID, subnet IDs, and security group rules required by the Pod network implementation.
Control Plane
A AWSManagedControlPlane object describes the control plane, which is the group of machines that run the Kubernetes control plane components, which include the etcd distributed database, the API server, the core controllers, and the scheduler. The object describes the configuration for these components. The object also has a reference to an infrastructure-specific object that describes the properties of all control plane machines.
Node Pool
A Node Pool is a collection of machines with identical properties. For example, a cluster might have one Node Pool with large memory capacity, another Node Pool with GPU support. Each Node Pool is described by three objects: The MachinePool references an object that describes the configuration of Kubernetes components (for example, kubelet) deployed on each node pool machine, and an infrastructure-specific object that describes the properties of all node pool machines. Here, it references a KubeadmConfigTemplate, and an AWSMachineTemplate object, which describes the instance type, the type of disk used, the size of the disk, among other properties.
For in-depth documentation about the objects, read Concepts in the Cluster API Book.
Wait for the cluster control-plane to be ready:
CODEkubectl wait --for=condition=ControlPlaneReady "clusters/${CLUSTER_NAME}" --timeout=20m
CODEcluster.cluster.x-k8s.io/eks-example condition met
The
READY
status will becomeTrue
after the cluster control-plane becomes ready in one of the following steps.Once the objects are created on the API server, the Cluster API controllers reconcile them. They create infrastructure and machines. As they progress, they update the Status of each object. Konvoy provides a command to describe the current status of the cluster:
CODEdkp describe cluster -c ${CLUSTER_NAME}
CODENAME READY SEVERITY REASON SINCE MESSAGE Cluster/eks-example True 10m ├─ControlPlane - AWSManagedControlPlane/eks-example-control-plane True 10m └─Workers └─MachineDeployment/eks-example-md-0 True 26s ├─Machine/eks-example-md-0-78fcd7c7b7-66ntt True 84s ├─Machine/eks-example-md-0-78fcd7c7b7-b9qmc True 84s ├─Machine/eks-example-md-0-78fcd7c7b7-v5vfq True 84s └─Machine/eks-example-md-0-78fcd7c7b7-zl6m2 True 84s
As they progress, the controllers also create Events. List the Events using this command:
CODEkubectl get events | grep ${CLUSTER_NAME}
For brevity, the example uses
grep
. It is also possible to use separate commands to get Events for specific objects. For example,kubectl get events --field-selector involvedObject.kind="AWSCluster"
andkubectl get events --field-selector involvedObject.kind="AWSMachine"

Known Limitations
Be aware of these limitations in the current release of Konvoy.
The Konvoy version used to create a workload cluster must match the Konvoy version used to delete a workload cluster.
EKS clusters cannot be Self-managed.
Konvoy supports deploying one workload cluster.
Konvoy generates a set of objects for one Node Pool.
Konvoy does not validate edits to cluster objects.
