What this is

This project is an automated way to install and deploy a kubernetes environment using ansible
It also deploys a webapp with 3 replicas and an Ingress controller as well as a database

At least 2 VMs are needed, but you can add more if you want

System requirements

Execute this script to ensure system requirements

chmod +x setup.sh
bash setup.sh

VMs requirements

All managed nodes in inventory must have:

  • Passwordless SSH access (ssh-copy-id to all the node beforehand) and don't forget access ssh from the master to the master
  • The user ansible-admin must exist on and have admin permissions under sudo
  • The password for the ansible-admin user must be the same across all the VMs

Usage

First copy the sample inventory to inventory.yml.

cp inventory-sample.yml inventory.yml

Second edit the inventory file to match your cluster setup. For example:

k3s_cluster:
  children:
    server:
      hosts:
        192.16.35.11:
    agent:
      hosts:
        192.16.35.12:
        192.16.35.13:

If needed, you can also edit vars section at the bottom to match your environment.

Start provisioning of the cluster using the following command:

ansible-playbook playbook/site.yml -i inventory.yml -K
