Installing kubelet and kubeadm
You will install these packages on all of your machines:
kubelet: the component that runs on all of the machines in your cluster and does things like starting pods and containers.
kubeadm: the command to bootstrap the cluster.
If the machine is running CentOS, run:
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
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
EOF
setenforce 0
yum install -y kubelet kubeadm
systemctl enable kubelet && systemctl start kubelet
Initializing your master
To initialize the master, pick one of the machines you previously installed kubeadm on, and run:
kubeadm init
