Update Instructions to join the microk8 group per on each node: You should be able to see the new node in a few seconds on the master with the following command: microk8s.kubectl get node

Now, you need to run the join command from another Pi you want to add to the cluster: microk8s.join :/įor example: microk8s.join 10.55.60.14:25000/JHpbBYMIevZSAMnmjMHmFwanrOYCWZLu This command will generate a connection string in the form of :/. On the chosen one, run the following command: sudo microk8s.add-node Now that you have MicroK8s installed on all boards, pick one is to be the master node of your cluster. MicroK8s is easy to use and comes with plenty of Kubernetes add-ons you can enable or disable.

  • To get the status of the cluster: microk8s.kubectl cluster-info.
  • You can easily enable Kubernetes add-ons, eg.
  • The stop command will stop all Kubernetes services: microk8s.stop.
  • The inspect command will give you the status of services: microk8s.inspect.
  • The start command will start all enabled Kubernetes services: microk8s.start.
    • For more information about which releases are available, run: snap info microk8sīefore going further here is a quick intro to the MicroK8s command line:

    For example, to follow the v1.17 series: sudo snap install microk8s -classic -channel=1.17/stableĬhannels are made up of a track (or series) and an expected level of stability, based on MicroK8s releases (Stable, Candidate, Beta, Edge).

    #Update docker and kubernetes on pi series

    To follow a specific Kubernetes upstream series it’s possible to select a channel during installation. MicroK8s is a snap and as such it will be automatically updated to newer releases of the package, which is following closely upstream Kubernetes releases.

Once that’s done we can now Install the MicroK8s snap: sudo snap install microk8s -classic Now save the file in your editor and reboot: sudo reboot

    The full line for this particular raspberry pi looks like this: cgroup_enable=memory cgroup_memory=1 net.ifnames=0 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait To do this you need to modify the configuration file /boot/firmware/cmdline.txt: sudo nano /boot/firmware/cmdline.txtĪnd add the following options: cgroup_enable=memory cgroup_memory=1 We need to enable c-groups so the kubelet will work out of the box. SSH into your first Pi and there is one thing we need to do before we get cracking. Once completed you will have MicroK8s installed and running everywhere. Installing MicroK8sįollow this section for each of your Pis. MicroK8s is only available for 64-bit Ubuntu images.Īfterwards you should be able to log in to your Pis on your network using their IP addresses. Follow it all the way until the install a desktop section.

    This tutorial will teach you how to get to this stage. Here are a couple of in-progress shots for reference:Įach Pi is going to need an Ubuntu server image and you’ll need to be able to SSH into them. If you have the PiHut Cluster Case that we used here, the assembly instructions are very straight forward. We recommend you do this at the start to have everything nicely organised before you get going. The time to build will vary depending on which rack you bought and how nimble your fingers are, but it shouldn’t take you longer than 45 minutes. If you have gone ahead and purchased a rack for your Pis now is the time to set it up. You will also need to have all of the boards on the same network, with a terminal window ready to connect to each Pi through SSH.

  • A cluster rack (Here we are using the Cluster Case from the PiHut).
  • A Cat5/6 network cable for each board is preferred, but Wi-FI setup is possible as well.

  • An HDMI cable if you’re using Pis 2 or 3 or a MicroHDMI cable for the Pi 4.
  • A microSD card per Pi (8GB recommended), flashed with an Ubuntu Server image.
  • A USB power-supply with as many ports as you have boards.
  • A micro-USB power cable for each Pi (USB-C for Pi4).
    • (You can use as many as you like, here we use 3)
  • A minimum of 2 Raspberry Pis, they need to be Pi 3B or later.
  • Managing the cluster: adding and removing nodes.
  • Joining multiple deployments to form a cluster.
  • Deploying Kubernetes on Raspberry Pi using MicroK8s.
