Play with Ansible and Terraform to make Self managed K8s Cluster

Description

This project automates the deployment of a Kubernetes cluster on AWS EC2 instances using Terraform for infrastructure provisioning and Ansible for installing Docker, kubeadm, and all necessary dependencies.

Prerequisites

Ensure you have the following installed and configured on your device:

Basic Kubeadm Cluster Diagram

Installation

Clone the repository:

git clone https://github.com/AB-Rhman/k8s-ec2-terrafrom.git
cd k8s-ec2-terrafrom

Usage

Provision Infrastructure

Initialize Terraform:
```
terraform init
```
Review the execution plan:
```
terraform plan
```
Apply the Terraform configuration:
```
terraform apply
```

SSH Access

Use the generated private key to SSH into your EC2 instances:

ssh -i privatekey.pem ubuntu@<ec2-public-ip> # find ip in /files/hosts

Run Ansible Playbook

Ensure required Ansible packages are installed:

ansible-galaxy install -r requirements.yml
ansible-galaxy collection install cloud.terraform

Create an Ansible vault file with your sudo password:
```
ansible-vault create vault.yml
```
Inside the vault.yml file, add:
```
ansible_become_pass: <your_sudo_password>
```

Run the Ansible playbook:

ansible-playbook -i inventory.yml playbook.yml --ask-vault-pass

OR You can use apply script to make all of the above

./apply-and-run-k8s.sh

Configure kubectl

Export the kubeconfig file:

export KUBECONFIG=/tmp/kubeconfig/config

Verify the connection to your Kubernetes cluster:
```
kubectl get nodes
```

Clean Up

Destroy all resources:
```
./destroy-all.sh
```

Features
