k3s-ansible's Introduction

Build a Kubernetes cluster using k3s via Ansible.

This repository is now part of https://github.com/k3s-io/k3s-ansible official repo in contrib/ansible directory. Anyway I'll write updates in order to make PM in k3s. Be my guest and feel free to contribute.

My blog post about these bunch of playbooks

Here is my post about k3s and Ansible provisionning (in French)

K3s Ansible Playbook

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

Debian 9
Ubuntu 16.04
CentOS 7

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

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.yml

Maybe this should be archived

Maybe this repo should be archived and the README should point to https://github.com/rancher/k3s-ansible ?

k3s with HA

@itwars great work. I am using k3s and its super fast.

I am looking around for a HA cluster k3s-ansible playbook. Yours is only with one master node, correct?

Is there a plan to make this to setup an HA cluster?

Thanks.

how to use/install this role?

hi,

i've tried to install this role with ansible-galaxy:
ansible-galaxy install git+https://github.com/itwars/k3s-ansible

and get this error:

[WARNING]: - k3s-ansible was NOT installed successfully: this role does not appear to have a meta/main.yml file.

ERROR! - you can use --ignore-errors to skip failed roles and finish processing the list.

small fix in README.md

ansible-playbook site.yml

instead of

ansible-playbook site.yaml

Warning using dashes in group names

Hi Vincent, just a silly note.
It seems ansible 2.8.4 doesn't like the dash in the cluster name (host.ini).

[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details
Not replacing invalid character(s) "{'-'}" in group name (k3s-cluster)

Thanks for your great playbook,
Piero

Download task fails on arm, still tries think is x86_64
