This git repository serves as a guide on how to install Kubernetes on to a Pi-Cluster. At certain point in this instruction page, we were unable to get work. We created an alternative approach that did work for us, and hopefully can work for you.
-
Follow instructions on this website up until running the script "install.sh":
https://kubecloud.io/setting-up-a-kubernetes-1-11-raspberry-pi-cluster-using-kubeadm-952bbda329c8 -
Skip creating the configuration file, it is not needed.
-
Run Command:
sudo swapoff -a -
Add
Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false"'to'/etc/systemd/system/kubelet.service.d/10-kubelet.conf' path. -
Run Command:
sudo systemctl daemon-reload -
Run Command:
sudo systemctl restart kubelet
For 5 and 6, you will want to give it some time until it is activated. Once it is activated you can proceed to the next step
- Initialize kubernetes as root in only the "master" pi.
- Run Command:
sudo kubeadm init --ignore-preflight-errors="all"
- Run Command:
mkdir -p .kube - Run Command:
sudo cp -i /etc/kubernetes/admin.conf .kube/config - Run Command:
sudo chown $(id -u):$(id -g) .kube/config - Once it's initialized, you will want to create the weave for the Rasberry pi's to perform as a cluster.
- Run Command:
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
- On "worker" pi's.
- Run Command:
sudo kubeadm join $MASTERIP:6443 --token $TOKEN --discovery-token-ca-cert-hash $HASH --ignore-preflight-errors="all"
