# 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:



- [X] Debian 

- [ ] Ubuntu 

- [ ] 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:



```

[master]

192.16.35.12



[node]

192.16.35.[10:11]



[kube-cluster:children]

master

node

```



Start provisioning of the cluster using the following command:



```

ansible-playbook site.yaml

```

ansible.cfg
