Known Limitations

hostPort doesn't work

This isn't really an issue of kube-aws but rather Kubernetes and/or CNI issue. Anyways, it doesn't work if hostNetwork: false.

If you want to deploy nginx-ingress-controller which requires hostPort, just set hostNetwork: true:

          hostNetwork: true
          - image:
            name: nginx-ingress-lb

Relevant kube-aws issue: does hostPort not work on kube-aws/CoreOS?

See the related upstream issue for more information.

This limitation is also documented in the official Kubernetes doc.
