If desired, join additional nodes to the master using the kubeadm join command provided in the kubeadm init output.
for a single-machine Kubernetes cluster run: If you want to be able to schedule pods on the master, e.g. # sudo chown $(id -u):$(id -g) $HOME/.kube/configĪdd hosts or configure master to run podsīy default, your cluster will not schedule pods on the master for security reasons. # sudo cp -i /etc/kubernetes/nf $HOME/.kube/config # kubeadm init -pod-network-cidr=10.244.0.0/16 -ignore-preflight-errors=allįollow the directions in the resulting output to configure kubectl: Also, we'll start by running kubeadm reset to ensure that we're working with from a clean slate: We specify a pod-network-cidr because flannel, which we'll use in this test, requires it, and we ignore preflight errors because because kubeadm looks in the wrong place for kernel config. Start the kubelet and initialize the kubernetes cluster.

#Install kubeadm centos 7 install
# rpm-ostree install kubernetes-kubeadm -r
Use package layering to install kubeadm on each host The CentOS Virtualization SIG provides a kubernetes-kubeadm that can be used with CentOS Atomic Host via rpm-ostree package layering.Ĭonfigure the Virt SIG kubernetes repo on each hostĬat /etc//virt7-kubernetes-110-candidate.repo Kubeadm is a tool for bootstrapping Kubernetes clusters that offers a really simple method of getting up and running with a single or multi-node cluster.
