I used below mentioned commands to remove kubernetes from my ubuntu 18.04 server.
kubeadm reset
sudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube*
sudo apt-get autoremove
sudo rm -rf ~/.kube
but still its showing :
Client Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.0", GitCommit:"2bd9643cee5b3b3a5ecbd3af49d09018f0773c77", GitTreeState:"clean", BuildDate:"2019-09-18T14:36:53Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server `localhost:8080 was refused - did you specify the right host or port? while running kubectl version .How can i completely remove kubectl from my ubuntu server 18.04 ?
Depending on the method you chose in https://kubernetes.io/docs/tasks/tools/install-kubectl/, it can be any of these:
Install kubectl binary via curl: sudo rm /usr/local/bin/kubectl
Download as part of the Google Cloud SDK: gcloud components remove kubectl
Install with snap on Ubuntu (just as Gparmar said): snap remove kubectl
In addition, you may need to remove the configuration files in ~/.kube.
If you exectute commands below:
kubeadm reset
sudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube*
sudo apt-get autoremove
sudo rm -rf ~/.kube
remember to restart computer.
