1. What kops version are you running? The command kops version, will display
this information.

2. What Kubernetes version are you running? kubectl version will print the
version if a cluster is running or provide the Kubernetes version specified as
a kops flag.

v1.18.9

3. What cloud provider are you using?

AWS

I'm testing KOPS 1.19 alpha5 and cluster is not validated when I set enablePrometheusMetrics under cilium sections:

  networking:
    cilium:
       enablePrometheusMetrics: true

As soon as I remove enablePrometheusMetrics KOPS can validate cluster.

I'm generating Terraform file(s) and then apply it for cluster creation.

Terraform v0.12.24
