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:
- Debian
- Ubuntu
- CentOS
on processor architecture:
- x64
- arm64
- armhf
System requirements
Deployment environment must have Ansible 2.4.0+ Master and nodes must have passwordless SSH access
Usage
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
Kubeconfig
To get access to your Kubernetes cluster just
scp debian@master_ip:~/.kube/config ~/.kube/config
