no InstanceGroup objects found

Error message

no InstanceGroup objects found

Guard in RunValidateCluster: the cluster exists but has zero InstanceGroup objects in the state store. There is nothing to validate node-wise, which usually means the cluster spec is incomplete or the wrong state store is being read.

Solutions

1. Run kops create instancegroup to add groups
