🚀 Jenkins Pipeline for Ansible Deployment

Navigate to Jenkins Dashboard → New Item → Pipeline and add the following script:

pipeline {
    agent any
    stages {
        stage('Checkout Code') {
            steps {
                git 'https://github.com/your-repo/ansible-playbooks.git'
            }
        }
        stage('Run Ansible Playbook') {
            steps {
                ansiblePlaybook credentialsId: 'ansible-ssh-key', inventory: 'inventory.ini', playbook: 'deploy.yml'
            }
        }
    }
}

✅ This pipeline:
✔️ Checks out the latest playbook from GitHub.
✔️ Executes Ansible playbook to configure servers automatically.
