Introduction to AWS EKS Connector

You can use Amazon EKS Connector to register and connect any conformant Kubernetes cluster to AWS and visualize it in the Amazon EKS console. After a cluster is connected, you can see the status, configuration, and workload in the Amazon EKS console. You can use this feature to view connected clusters in Amazon EKS console, but you can not control them.

The Amazon EKS Connector can connect the following kinds of Kubernetes clusters to Amazon EKS. The Amazon EKS Connector is also an open supply project on Github.

• The clusters are on-premises.
• There are clusters on Amazon Elastic Compute Cloud.
• Other cloud providers have managed clusters.

Amazon EKS Connector considerations

Understand the following before using Amazon EKS Connector:

• You should have administrative privileges to the Kubernetes cluster to join the cluster to Amazon EKS.
• Before connecting, the cluster must have Linux worker nodes present. ARM worker nodes aren't supported.
• Outbound access to the ssm. and ssmmessages is required for you to have worker nodes in your cluster.
• Up to 10 clusters can be connected by default. The service quota console can be used to request an increase.
• Only the Amazon EKS RegisterCluster, ListClusters, DescribeCluster, and DeregisterCluster are supported by external Kubernetes clusters.
• Permissions are needed to register a cluster.

1. eks:RegisterCluster
2. ssm:CreateActivation
3. ssm:DeleteActivation
4. iam:PassRole

• Permissions are needed to deregister a cluster.

1. eks:DeregisterCluster
2. ssm:DeleteActivation
3. ssm:DeregisterManagedInstance

Required IAM roles for Amazon EKS Connector

The following two roles are required for using the Amazon EKS Connector.

• The Amazon EKS Connector service-linked role is created when you register the cluster.
• The Amazon EKS Connector agent IAM role have to be created manually. See Amazon EKS connector IAM role for details.

To enable cluster and workload view permission for another user, you must apply the eks-connector and Amazon EKS Connector cluster roles to your cluster.
