To install Kubernetes packages in CentOS perform the following steps:

1. As with Ubuntu, new repository information needs to be added:

$ sudo vim /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
       https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg

2. Now, we are ready to pull the packages from the Kubernetes source base via the yum command:

// on Kubernetes master
$ sudo yum install -y kubelet kubeadm kubectl
// on Kubernetes node
$ sudo yum install -y kubelet

3. No matter what OS it is, check the version of the package you get!

// take it easy! server connection failed since there is not server running
$ kubectl version
