I’ve seen this most commonly with ENIs that the AWS VPC CNI allocates. They have had a lot of fixes in the last few releases of the CNI to address issues related to this. If you are on the latest version of the Pulumi-EKS package, it should pull in the latest CNI by default which had some fixes that addressed similar failures we had seen occasionally in our own CI.

See also https://github.com/pulumi/pulumi-eks/pull/214 which cross references some of the relevant CNI fixes.

08/28/2019, 3:55 PMyep, had a look through that - not sure what the fix is though, if any?

My understanding is that EKS more or less requires VPC CNI. See for example https://github.com/aws/amazon-vpc-cni-k8s/issues/176.

08/28/2019, 4:09 PMafaik vpc-cni isn’t required, and you can use a “standard” overlay network instead https://github.com/aws/amazon-vpc-cni-k8s/issues/176

08/28/2019, 4:10 PMmainly I’m just wondering what my options are, as I seem to have fallen at the first hurdle here. Run Pulumi to create a vanilla EKS cluster with workers, install nginx-ingress, uninstall nginx-ingress, run pulumi destroy, hit error. This doesn’t seem very edge-casey to me
