I'm trying to initialize a cluster with a configuration file in Kubernetes, The version for the kubeadm,kubectl and kubelet and as following for all nodes.
1.kubeadm
kubeadm version: &version.Info{Major:"1", Minor:"17", GitVersion:"v1.17.0", GitCommit:"70132b0f130acc0bed193d9ba59dd186f0e634cf", GitTreeState:"clean", BuildDate:"2019-12-07T21:17:50Z", GoVersion:"go1.13.4", Compiler:"gc", Platform:"linux/amd64"}2.kubectl
Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.3", GitCommit:"2e7996e3e2712684bc73f0dec0200d64eec7fe40", GitTreeState:"clean", BuildDate:"2020-05-20T12:52:00Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}3.kubelet
Kubernetes v1.18.3But still Iam getting the error that my control plane version is lesser as mentioned following:
this version of kubeadm only supports deploying clusters with the control plane version >= 1.16.0. Current version: v1.12.0
To see the stack trace of this error execute with --v=5 or higherWhy am I getting this error.? Can someone help me with this.Thanks in advance for your time – if I’ve missed out anything, over- or under-emphasised a specific point let me know in the comments.

apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.17.0
apiServer:
