Install below packages on all of your machines:

  • kubeadm: the command to bootstrap the cluster.
  • kubelet: the component that runs on all of the machines in your cluster and does things like starting pods and containers.
  • kubectl: the command line util to talk to your cluster.

Note : kubeadm will not install or manage kubelet or kubectl for you, so you will need to ensure they match the version of the Kubernetes control panel you want kubeadm to install for you.

 If you do not, there is a risk of a version skew occurring that can lead to unexpected, buggy behavior. 

However, one minor version skew between the kubelet and the control plane is supported, but the kubelet version may never exceed the API server version.

For example, kubelet running 1.7.0 should be fully compatible with a 1.8.0 API server, but not vice versa.

Below is the example for installing in Debian/Ubuntu flavours:

# apt-get update && apt-get install -y apt-transport-https curl
# curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
# apt-get update
# apt-get install -y kubelet kubeadm kubectl
# apt-mark hold kubelet kubeadm kubectl

  • Configure cgroup driver used by kubelet on Master Node.
  • When using Docker, kubeadm will automatically detect the cgroup driver for the kubelet and set it in the /var/lib/kubelet/kubeadm-flags.env file during runtime.
  • If you are using a different CRI, you have to modify the file /etc/default/kubelet with your cgroup-driver value, like so: KUBELET_KUBEADM_EXTRA_ARGS=--cgroup-driver=<value>

  • This file will be used by kubeadm init and kubeadm join to source extra user-defined arguments for the kubelet.
  • Please mind, that you only have to do that if the cgroup driver of your CRI is not cgroupfs, because that is the default value in the kubelet already.
  • Restarting the kubelet is required.
