Ansible Kubernetes Deployment

This repository contains Ansible playbooks and scripts for deploying a Kubernetes cluster with Kubeadm.

Prerequisites

• Infra provisioned through IAC: Deployed infrastructure using terraform multi cloud iac (as it contains a module to automatically update inventory for ansible scripts given that ansible repo and terraform repo are in the same directories).
• Ansible Controller Scripts: Run the setupiptables.yml and acceptfingerprint.yml from ansible_controller_setup repository . Link in Additional Resources .
• Software Requirements: Ensure Ansible cli is installed.

Installation

Clone the repository to your local machine to get started with the Kubernetes deployment:

git clone https://github.com/Moody-san/ansible-k8s-deployment.git
cd ansible-k8s-deployment/playbooks

Usage

ansible-playbook initmaster.yml -i ../inventory/oracleinventory
ansible-playbook addworkernodes.yml -i ../inventory/oracleinventory
ansible-playbook addcontrolnodes.yml -i ../inventory/oracleinventory
ansible-playbook addistiomesh.yml -i ../inventory/oracleinventory

Configuration

you can use the -l limit tag to add specific nodes only for example

ansible-playbook addworkernodes.yml -i ../inventory/oracleinventory -l oraclemaster,oracleworker

Additional Resources

• MariaDB Cluster Setup: For setting up a MariaDB cluster with Kubernetes-based failover, visit ansible-galeracluster-deployment.
• CI/CD and Automation: For CI/CD and other automation scripts, refer to ansible-controller-setup.

Notes

• You will be prompted for your private load balancer ip when initializing kubernetes cluster . The one provisioned through the terraform .
• When using limit with for example with addworkernodes oraclemaster is required as we use oracle master to generate the join string .
