Jenkins Projects : 6 Mini Projects

In this post, we are 6 covering mini-projects those you can implement in Jenkins, covering a range of skills and applications:

Project 1: Automated Website Deployment

Requirement: Streamline the website deployment process from development to production.
Summary: Trigger website updates upon code changes, automatically building, testing, and deploying to the target server.
Tools/Services:
- Git (or other version control system)
- Jenkins
- Deployment tool (e.g., Ansible, Shell scripts)
- Web Server (e.g., Apache, Nginx)
Workflow:
1. Developer commits code changes to the repository.
2. Jenkins detects the change and triggers a pipeline.
3. Jenkins builds the code (if applicable).
4. Jenkins executes tests (unit, integration).
5. Upon successful tests, Jenkins deploys the updated code to a staging server.
6. Optional: Run smoke tests on the staging environment.
7. Jenkins deploys the code to the production server.

Requirement: Automate the creation and distribution of Docker images.
Summary: Create a pipeline that builds Docker images from source code and pushes them to a registry.
Tools/Services:
- Docker
- Docker registry (e.g., Docker Hub, Google Container Registry)
- Jenkins
Workflow:
1. Developer commits changes to the Dockerfile and application code.
2. Jenkins detects the change and triggers a pipeline.
3. Jenkins builds the Docker image.
4. Jenkins tags the image.
5. Jenkins pushes the image to the Docker registry.

Requirement: Automate the creation and management of AWS resources.
Summary: Use Jenkins and infrastructure-as-code tools to manage AWS deployments.
Tools/Services:
- AWS
- Jenkins
- CloudFormation or Terraform
Workflow:
1. Developer modifies infrastructure templates (CloudFormation or Terraform).
2. Jenkins detects the change and triggers a pipeline.
3. Jenkins provisions or updates the AWS infrastructure based on the templates.

Requirement: Schedule regular database backups and provide the ability to restore on demand.
Summary: Create a pipeline to reliably back up databases and restore them if needed.
Tools/Services:
- Jenkins
- Database system (e.g., MySQL, PostgreSQL)
- Database backup tools (e.g., mysqldump, pg_dump)
- Secure storage for backups (e.g., S3 bucket)
Workflow:
1. Jenkins triggers a pipeline on a defined schedule (e.g., nightly).
2. Jenkins performs a database backup.
3. Jenkins stores the backup in a secure location.
4. (On-demand restoration) Jenkins retrieves a specified backup.
5. Jenkins restores the database from the backup.

Requirement: Implement continuous integration and delivery for a mobile application.
Summary: Build, test, and potentially deploy mobile app updates automatically.
Tools/Services:
- Jenkins
- Mobile app build tools (e.g., Gradle, Xcode)
- Mobile testing frameworks (e.g., Appium, Espresso)
- App distribution platform (e.g., Google Play Store, Apple App Store)
Workflow:
1. Developer commits code changes.
2. Jenkins triggers the mobile app build pipeline.
3. Jenkins runs unit and UI tests.
4. Upon successful testing, Jenkins may deploy to an internal testing platform or initiate an app store submission process.

Requirement: Gather telemetry data from IoT devices and trigger actions based on specific conditions.
Summary: Monitor IoT devices, analyze data, and react to events.
Tools/Services:
- Jenkins
- IoT data platform (e.g., AWS IoT, Azure IoT Hub, or a time-series database like InfluxDB)
Workflow:
1. IoT devices send data to the IoT data platform.
2. Jenkins periodically pulls data or subscribes for real-time updates.
3. Jenkins analyzes the data.
4. Jenkins triggers actions based on rules (e.g., send alerts, perform device updates).
