RBAC permissions or bindings aren't configured properly

If you experience any RBAC permissions or binding issues, verify that the aws-batch Kubernetes role can access the Kubernetes namespace:

$ kubectl get namespace namespace --as=aws-batch

$ kubectl auth can-i get ns --as=aws-batch

You can also use the kubectl describe command to view the authorizations for a cluster role or Kubernetes namespace.

$ kubectl describe clusterrole aws-batch-cluster-role

The following is example output.

To resolve this issue, re-apply the RBAC permissions and rolebinding commands. For more information, see Step 2: Prepare your Amazon EKS cluster for Amazon Batch.
