Ansible Playbook for Deploying K3s on Raspberry Pis.

Pi K3s

Ansible playbook for deploying kubernetes to cluster of Raspberry Pis. I personally use this on a cluster of Raspberry Pi 4s, but earlier Raspberry Pis should work fine too.

Requirements and Assumptions

• Latest Ansible (as of this writing)
• Raspberry Pis with SSH already enabled. (e.g touch /boot/ssh on all)

Set up

• Clone this Repo and cd into the source.
• Update ./inventory with your own IP addresses.
• Test the connection ansible -m ping all
• Apply the playbook ansible-playbook main.yml

Optional

Connect to the cluster from your development computer

ssh <user>@<ip_address> sudo cat /etc/rancher/k3s/k3s.yaml > ~/.kube/pi_cluster.yml
export KUBECONFIG=$HOME/.kube/pi_cluster.yml

FAQ

Q: I'm having trouble connecting to the cluster.

A: Update the ssh configuration as needed in ansible.cfg
