Start with the request and the Kubernetes documentation on imagePullSecret, then compare its pod- and namespace-level scope with the requested node- or cluster-level authentication. The payload names no repository files, tests, or entry points; done would require a defined EKS approach for authenticating node image pulls from private registries.
