Build a Kubernetes cluster using k3s via Ansible

K3s Ansible Playbook

Build a Kubernetes cluster using Ansible with k3s. The goal is easily install a Kubernetes cluster on machines running:

on processor architecture:

Deployment environment must have Ansible 2.4.0+ Master and nodes must have passwordless SSH access

First create a new directory based on the sample directory within the inventory directory:

cp -R inventory/sample inventory/my-cluster

Second, edit inventory/my-cluster/hosts.ini to match the system information gathered above. For example:

[master]
192.16.35.12

[node]
192.16.35.[10:11]

[k3s_cluster:children]
master
node

If needed, you can also edit inventory/my-cluster/group_vars/all.yml to match your environment.

Start provisioning of the cluster using the following command:

ansible-playbook site.yml -i inventory/my-cluster/hosts.ini

To get access to your Kubernetes cluster just

scp debian@master_ip:~/.kube/config ~/.kube/config
