Context for the Shared Cluster

This documentation describes the legacy CDK implementation, which will be deprecated in an upcoming release. We strongly recommend that you transition to the current CDK implementation as soon as possible.

Kubernetes uses contexts to access Kubernetes clusters. Before you can access the shared cluster, you must create a context on your local computer if it’s not already present.

To create a context for the shared cluster:

  1. Run the kubectx command and review the output. The current Kubernetes context is highlighted:

    • If the current context references the shared cluster, there is nothing further to do. Proceed to Namespace.

    • If the context of the shared cluster is present in the kubectx command output, set the context as follows:

      $ kubectx my-context
      Switched to context "my-context".

      After you have set the context, proceed to Namespace.

    • If the context of the shared cluster is not present in the kubectx command output, continue to the next step.

  2. Run the aws configure command. This command logs you in to AWS and sets the AWS region. Use the access key ID, secret access key, and region you obtained from your cluster administrator. You do not need to specify a value for the default output format:

    $ aws configure
    AWS Access Key ID [None]:
    AWS Secret Access Key [None]:
    Default region name [None]:
    Default output format [None]:
  3. Run the following command. Use the cluster name you obtained from your cluster administrator:

    $ aws eks update-kubeconfig --name my-cluster
    Added new context arn:aws:eks:us-east-1:813759318741:cluster/my-cluster
    to /Users/my-user-name/.kube/config
  4. Run the kubectx command again and verify that the context for your Kubernetes cluster is now the current context.

In Amazon EKS environments, the cluster owner must grant access to a user before the user can access cluster resources. For details about how the cluster owner can grant you access to the cluster, refer the cluster owner to Cluster Access for Multiple AWS Users.
