I am using the following kubeadmin config with external etcd setup for HA kubernetes setup following https://kubernetes.io/docs/setup/independent/high-availability/#external-etcd-nodes in bare metal server with centos7.
etcd version - v3.2.26
kind: ClusterConfiguration
kubernetesVersion: v1.13.1
apiServer:
certSANs:
- "k8-master01.loc.prov.domain.tld"
controlPlaneEndpoint: "k8-master01.loc.prov.domain.tld:8080"
etcd:
external:
endpoints:
- https://k8-master01.loc.prov.domain.tld:2379
- https://k8-master02.loc.prov.domain.tld:2379
- https://k8-master03.loc.prov.domain.tld:2379
caFile: /etc/kubernetes/pki/etcd/ca.crt
certFile: /etc/kubernetes/pki/apiserver-etcd-client.crt
keyFile: /etc/kubernetes/pki/apiserver-etcd-client.key
However init keeps failing at following step:
I0204 15:04:24.985393 142883 uploadconfig.go:133] [upload-config] Preserving the CRISocket information for the control-plane node

It keeps retrying and then eventually times out.
error execution phase upload-config/kubelet: Error writing Crisocket information for the control-plane node: timed out waiting for the condition
( Hostname has been fuzzed in above log )
Any suggestions as to how we can proceed?
