My RKE2 cluster using Ansible.

Primary LanguageShell

my-RKE2-cluster-ansible 👋

This is a RKE2 cluster deploying using Ansible.

RKE2

Requirements

  • 5 servers - 3 RKE2servers, 2 RKE2 agents;
  • OS - Ubuntu 20.04.4 LTS;
  • Ansible version - ansible 2.10.3;
  • ansible.utils that's in requirements.yml;
  • For firewall rules between the nodes see RKE requirements above;

If you got this error trying to install the ansible.utils:

⇒ ansible-galaxy collection install -r requirements.yml
Starting galaxy collection install process
Process install dependency map
ERROR! Unknown error when attempting to call Galaxy at 'https://galaxy.ansible.com/api/': <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1123)>

This workaround here it worked for me.

Usage

  • This project it's divided in three parts roles containing a common role common_setup for all of the roles;
  • To create the cluster we must first run the role first_node which will set up the first node and create the token needed for the remaining nodes;
  • The RKE2 version for the cluster it's setting on the command line using the argument --extra-vars;
  • For this lab I used v1.23.16+rke2r1;
  • For other releases available please check https://github.com/rancher/rke2/releases;

How to

ansible-playbook -i hosts main.yml --limit first_node --tags "first_node" --extra-vars "rke2_version=v1.23.16+rke2r1"
ansible-playbook -i hosts main.yml --limit rke2_servers --tags "rke2_servers" --extra-vars "rke2_version=v1.23.16+rke2r1"
ansible-playbook -i hosts main.yml --limit rke2_agents --tags "rke2_agents" --extra-vars "rke2_version=v1.23.16+rke2r1"

Accessing the Cluster from Outside with kubectl

If everything went well there will be a copy of the /etc/rancher/rke2/rke2.yaml on buffer directory. To access the cluster replace 127.0.0.1 with the IP or hostname of your RKE2 server so in that way kubectl can now manage your RKE2 cluster from your workstation.
