Prerequisites:

• Ubuntu 22.04 or compatible Linux distribution
• Ansible installed (for running Ansible playbooks)
• Kubernetes knowledge

Create a inventory file:

[control_plane]
master-node ansible_host=192.168.X.A

[workers]
worker-node1 ansible_host=192.168.X.B
worker-node2 ansible_host=192.168.X.C

[all:vars]
ansible_python_interpreter=/usr/bin/python3

[control_plane:vars]
ansible_ssh_private_key_file= /root/.ssh/id_rsa
ansible_user=root

[workers:vars]
ansible_ssh_private_key_file= /root/.ssh/id_rsa
ansible_user=root

To set up a gitlab instance, run the following Ansible playbook:

---
- name: Setup Kubernetes Cluster
  hosts: all
  become: true
  roles:
    - k8s-cluster-with-ansible

Executing the role to install gitlab server

ansible-playbook -i inventory setup_kubernetes.yml
