GitHub Integration

GitHub integration in Jenkins allows you to connect your Jenkins automation server with your GitHub repositories, enabling you to automate various aspects of your software development workflow. This integration can streamline processes such as continuous integration, automated testing, and deployment.

GitHub WebHooks

GitHub Webhooks are a powerful feature that allows you to automate and extend the functionality of your GitHub repositories. They work by sending HTTP POST requests to a specified URL (known as a webhook endpoint) whenever certain events occur within a GitHub repository. Here are some key points about GitHub Webhooks:

1. Event Trigger: GitHub Webhooks are triggered by various events that occur within a GitHub repository. Common events include:

   • Code pushes

   • Pull request creations, updates, or closures

   • Issues and issue comments

   • Repository or branch creations, deletions, or updates

   • Release creations or deletions

   • Many other repository-related actions

2. Payload: When an event occurs, GitHub sends a JSON payload containing information about the event to the configured webhook endpoint. This payload typically includes details such as the event type, the repository involved, and specific data related to the event.

3. Webhook Endpoint: To use GitHub Webhooks, you need to provide a URL where GitHub can send the HTTP POST requests. This URL should be accessible over the internet. Many organizations use web applications or services to receive and process webhook payloads.

4. Automation: Webhooks enable automation and integration with external tools and services. For example, you can set up a webhook to trigger a Continuous Integration/Continuous Deployment (CI/CD) pipeline whenever code is pushed to a repository. This automates the build and deployment process.

5. Customization: You can configure webhooks to respond differently to different events. For example, you might have different actions for code push events versus pull request events. This customization allows you to tailor your automation to your specific needs.

6. Security: GitHub Webhooks can be secured using secret tokens. When configuring a webhook, you can define a secret that GitHub includes in the payload. The receiving server can use this secret to verify the authenticity of the webhook request.

7. Real-time: Webhooks provide real-time notifications. As soon as an event occurs, GitHub sends the webhook payload to the endpoint, allowing for immediate actions and responses.

8. GitHub Actions: While GitHub Webhooks are a powerful way to integrate external services, GitHub also offers its own built-in automation platform called GitHub Actions. GitHub Actions allows you to define custom workflows directly in your repository for various events, reducing the need for external services in some cases.

Task-01

• Fork this repository:

• Create a connection to your Jenkins job and your GitHub Repository via GitHub Integration.

• Read About GitHub WebHooks and make sure you have CICD setup

we had already created ci-cd in #Day23 task you can refer my previous blog . From Step 2 we can integrate through webhook

Step 1: Open the GitHub repository. Go to settings and then click on webhooks.

Step 2: Click the “Add webhook” button and add the Payload URL

So I changed the heading and Git Webhooks automatically trigger my Jenkins Pipeline

Task-02

In the Execute shell run the application using Docker compose

You will have to make a Docker Compose file for this Project (Can be a good open source contribution)

Run the project and give yourself a treat:)
