To retrieve the values for `CLUSTER_CA`, `APISERVER_ENDPOINT`, and `CLUSTER_ID` of your Amazon EKS local cluster, run the following AWS CLI commands. Replace cluster-name with the name of your cluster and region (for example, us-east-1) with your cluster’s AWS Region.

** *DisableIMDSv1*: By default, each node supports the Instance Metadata Service Version 1 (IMDSv1) and IMDSv2. You can disable IMDSv1. To prevent future nodes and [.noloc]`Pods` in the node group from using IMDSv1, set *DisableIMDSv1* to *true*. For more information about IMDS, see link:AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html[Configuring the instance metadata service,type="documentation"]. For more information about restricting access to it on your nodes, see https://aws.github.io/aws-eks-best-practices/security/docs/iam/#restrict-access-to-the-instance-profile-assigned-to-the-worker-node[Restrict access to the instance profile assigned to the worker node].
** *VpcId*: Enter the ID for the <<creating-a-vpc,VPC>> that you created. Before choosing a VPC, review <<outposts-vpc-requirements,VPC requirements and considerations>>.
** *Subnets*: If your cluster is on an Outpost, then choose at least one private subnet in your VPC. Before choosing subnets, review <<outposts-subnet-requirements,Subnet requirements and considerations>>. You can see which subnets are private by opening each subnet link from the *Networking* tab of your cluster.
