I came across a problem: the storageClass can not create PV automatically because of ‘unexpected error getting claim reference: selfLink was empty, can’t make reference’. I have got the method to solve it, but it needs to find out a file called ‘kube-apisverer.yaml’. Now I really can not figure out where this file is.
The option to configure Kubernetes components is described on Rancher Docs: Cluster Configuration and the linked RKE docs
