Installing K3s
We will install K3s using ansible.
Download or clone the k3s-ansible repository, modify the playbook inventory, and run it:
  1. 1.
    Download using the 'Download ZIP' link on GitHub on https://github.com/rancher/k3s-ansible
  2. 2.
    Edit the Ansible inventory file inventory/hosts.ini, and replace the examples with the IPs or hostnames of your master and nodes. This file describes the K3s masters and nodes to Ansible as it installs K3s.
  3. 3.
    Edit the inventory/group_vars/all.yml file and change the ansible_user to pirate.
  4. 4.
    Run ansible-playbook site.yml -i inventory/hosts.ini and wait.
To connect to the cluster, once it's built, you need to grab the kubectl configuration from the master:
1
scp [email protected]:~/.kube/config ~/.kube/config-turing-pi
Copied!
Make sure you have kubectl installed on your computer (you can install it following these directions).
Then set the KUBECONFIG environment variable, and start running kubectl commands:
1
export KUBECONFIG=~/.kube/config-turing-pi
2
kubectl get nodes
Copied!
You should get a list of all the Pi servers; if you do, congratulations! Your cluster is up and running.
This guide is based on the article Installing K3s Kubernetes on the Turing Pi by Jeff Geerling
