Unable to dry run when provider is eks

[mneil]

mu.yml

---
environments:
  - name: acceptance
    provider: eks
  - name: production
    provider: eks
service:
    acceptance:
      disabled: true
    production:
      disabled: true

Run mu -d env up acceptance

What I expect to happen: CFN templates generated in a temporary folder.

What actually happens: I receive an error during the "Upserting environment 'acceptance'" stage>

ResourceNotFoundException: No cluster found for name: mu-eks-workshop-environment-acceptance.
        status code: 404, request id: afeea07c-e2cb-11e8-9d24-7f94881ec1a7
