Cluster Made Easy!

You can use Multipass to create two Ubuntu VMs and then set up a Kubernetes cluster on these two VMs. It only takes less than 6 minutes.

If you substract the time, it only takes 5 minutes and 26 seconds.

Installation steps

These are the links to install and create kubernetes cluster,

Step 1. Create two Ubuntu VMs on macOS pane,

git clone https://github.com/yujunliang/multipass-kubernetes.git
cd multipass-kubernetes/multipass
./launch-2vm.sh

Step 2. On cks-master pane,

cd multipass
./ssh-to-cks-master.sh

when in cks-master VM, execute the following commands

sudo -i
git clone https://github.com/yujunliang/multipass-kubernetes.git
cd multipass-kubernetes/cks-master
./install-all.sh

copy the output like this,

kubeadm join 192.168.64.3:6443 --token al0kvi.x60mi1xj4zesqnq3     --discovery-token-ca-cert-hash sha256:f4ff0c7684bbac599a8208b94bb28e451023662ab51bc1ce16f60a855a85e2a5

Step 3. On cks-worker pane,

cd multipass
./ssh-to-cks-worker.sh

when in cks-worker,execute the following commands

sudo -i
git clone https://github.com/yujunliang/multipass-kubernetes.git
cd multipass-kubernetes/cks-worker
./install-all.sh

then run what you copied from Step 2, something like this,

kubeadm join 192.168.64.3:6443 --token al0kvi.x60mi1xj4zesqnq3     --discovery-token-ca-cert-hash sha256:f4ff0c7684bbac599a8208b94bb28e451023662ab51bc1ce16f60a855a85e2a5

Step 4. On second window, cks-master

# kubectl get nodes
NAME         STATUS   ROLES    AGE   VERSION
cks-master   Ready    master   34h   v1.19.0
cks-worker   Ready    <none>   34h   v1.19.0

# kubectl run nginx --image=nginx
pod/nginx created

# kubectl get pod
NAME    READY   STATUS    RESTARTS   AGE
nginx   1/1     Running   0          19s
