This post documents my experiences with trying to run kubernetes on a five-node Raspberry Pip 2 cluster.

I started by setting up each of the five Raspberry Pis with Hypriot v1.1.1.

I have internal DNS & DHCP services on my Lab network so I used hardware addresses to ensure each node has a DNS entry and always gets the same IP, as follows:

On each node, I ensured all packages were up-to-date:

apt-get update && apt-get -y upgrade

I used the kubeadm guide for the following steps.

Add a new repo and install various kubernetes commands on all nodes:

curl -s | apt-key add -
cat <<EOF > /etc/apt/sources.list.d/kubernetes.list
deb kubernetes-xenial main

apt-get update
apt-get install -y kubelet kubeadm kubectl kubernetes-cni

I designated node01 as the master and ran the following commands on the master only:

Initialise the master:

kubeadm init --pod-network-cidr=

Install flannel networking:

export ARCH=arm
curl -sSL "" | sed "s/amd64/${ARCH}/g" | kubectl create -f -

Check everything is running OK:

$ kubectl get pods --all-namespaces
NAMESPACE     NAME                                          READY     STATUS    RESTARTS   AGE
kube-system   dummy-2501624643-8gpcm                        1/1       Running   0          24m
kube-system                      1/1       Running   0          23m
kube-system            1/1       Running   0          23m
kube-system   1/1       Running   0          23m
kube-system   kube-discovery-2202902116-j9zjn               1/1       Running   0          24m
kube-system   kube-dns-2334855451-lu3qh                     3/3       Running   0          22m
kube-system   kube-flannel-ds-p32x1                         2/2       Running   0          15m
kube-system   kube-proxy-28edm                              1/1       Running   0          22m
kube-system            1/1       Running   0          23m

Join the other nodes:

kubeadm join --token=c2a0a6.7dd1d5b1c26795ef

Check they've all joined correctly:

$ kubectl get nodes

NAME                  STATUS    AGE   Ready     27m   Ready     45s   Ready     54s   Ready     16s   Ready     25s

Install the dashboard:

export ARCH=arm
curl -sSL "" | sed "s/amd64/${ARCH}/g" | kubectl create -f -

You should now have something like this:

$ kubectl get pods --all-namespaces
