This document outlines how to install Calico, as well as a as single node etcd cluster for use by Calico on a Kubernetes cluster created by kubeadm.
Users who have deployed their own etcd cluster outside of kubeadm should use the Calico only manifest instead, as it does not deploy its own etcd.
You can easily create a cluster compatible with this manifest by following the official kubeadm guide.
To install this Calico and a single node etcd, run the following command:
kubectl apply -f http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml
You can download the addon manfiest here
This manifest deploys the standard Calico components described here as well as a dedicated Calico etcd node on the Kubernetes master. Note that in a production cluster, it is recommended you use a secure, replicated etcd cluster.
This manifest uses a node label to select the master node on which Calico’s etcd is run. This label is configured automatically on the master when using kubeadm.
To check if the required label is applied, run the following command:
$ kubectl get node <master_name> -o yaml | grep kubeadm kubeadm.alpha.kubernetes.io/role: master
