 # Build a Kubernetes cluster using k3s via Ansible
 
-Author: <https://github.com/itwars>
-
-## K3s Ansible Playbook
-
-Build a Kubernetes cluster using Ansible with k3s. The goal is easily install a Kubernetes cluster on machines running:
-
-- [X] Debian
-- [ ] Ubuntu
-- [X] CentOS
-
-on processor architecture:
-
-- [X] x64
-- [X] arm64
-- [X] armhf
-
-## System requirements
-
-Deployment environment must have Ansible 2.4.0+
-Master and nodes must have passwordless SSH access
-
-## Usage
-
-Add the system information gathered above into a file called hosts.ini. For example:
-
-```bash
-[master]
-192.16.35.12
-
-[node]
-192.16.35.[10:11]
-
-[k3s-cluster:children]
-master
-node
-
-```
-
-Start provisioning of the cluster using the following command:
-
-```bash
-ansible-playbook site.yml -i inventory/hosts.ini
-```
-
-## Kubeconfig
-
-To get access to your **Kubernetes** cluster just
-
-```bash
-scp debian@master_pi:~/.kube/config ~/.kube/config
-```
-
+The ansible playbook was moved to https://github.com/rancher/k3s-ansible
