🔧 Jenkins Configuration

1. Create a Pipeline in Jenkins named `ai-devops-pipeline1`.
2. Use `Pipeline script from SCM`.
3. Connect your GitHub repo.
4. Jenkinsfile content:

```groovy pipeline { agent any

stages {
    stage('Build Docker Image') {
        steps {
            sh 'docker build -t your-dockerhub-username/your-image-name .'
        }
    }
    stage('Push Docker Image') {
        steps {
            withCredentials([usernamePassword(credentialsId: 'docker-hub-credentials', usernameVariable: 'DOCKER_USER', passwordVariable: 'DOCKER_PASS')]) {
                sh 'echo \$DOCKER_PASS | docker login -u \$DOCKER_USER --password-stdin'
                sh 'docker push your-dockerhub-username/your-image-name'
            }
        }
    }
}

} ```

📌 Notes

• Replace `your-dockerhub-username/your-image-name` with your actual Docker Hub repo.
• Replace `docker-hub-credentials` with the correct Jenkins credential ID.

✅ Result

Once pushed, Jenkins will automatically:

1. Clone the repo.
2. Build the Docker image.
3. Push it to Docker Hub.
