Node Todo App with CI/CD Visitors

This is a simple to-do app that uses Node.js, Express, and EJS. It also uses Jenkins and Docker Compose for continuous integration and deployment.

Prerequisites

To run this app, you need to have:

  • Git installed on your machine.
  • Jenkins installed and running on your machine or server.
  • Docker and Docker Compose installed on your machine or server.

Steps

Step 1: Clone the Repository

To clone the repository, open a terminal or command prompt and run the following command:

git clone https://github.com/ajitfawade/node-todo-cicd.git

This will create a folder named node-todo-cicd in your current directory.

Step 2: Add a Webhook

To add a webhook, go to your GitHub repository and click on Settings. Then click on Webhooks and then on Add webhook.

Fill in the form as follows:

  • Payload URL: Enter your Jenkins URL followed by /github-webhook/. For example, http://example.com/github-webhook/.
  • Content type: Select application/json.
  • Secret: Leave it blank.
  • SSL verification: Select Enable SSL verification if your Jenkins URL uses HTTPS, otherwise select Disable SSL verification.
  • Which events would you like to trigger this webhook?: Select Just the push event.
  • Active: Check this box.

Click on Add webhook to create the webhook.

You can test the webhook by clicking on Edit and then on Test. You should see a green check mark indicating that the webhook was delivered successfully.

Step 3: Deploy the App

To deploy the app, go to your Jenkins dashboard and click on New Item.

Enter a name for your job (e.g., Node Todo App) and select Freestyle project. Then click OK.

On the configuration page, you can add some descriptions for your job if you want.

Under Source Code Management, select Git and enter the repository URL: [https://github.com/ajitfawade/node-todo-cicd.git]. You can leave the other fields as default.

Under Build Triggers, select GitHub hook trigger for GITScm polling. This will enable the job to be triggered by GitHub webhooks.

Under Build, click on Add build step and select Execute shell (or Execute Windows batch command if you are using Windows). This will allow you to run any shell or batch command as part of your job.

In the text area that appears, enter the command docker-compose up -d --build to build and run the app using Docker Compose. The -d flag runs the container in detached mode and the --build flag forces a rebuild of the image if there are any changes.

Click Save to save your job.

Now, whenever you push any changes to your GitHub repository, your Jenkins job will be triggered automatically and deploy your app using Docker Compose.

You can also manually trigger your job by clicking on Build Now on your Jenkins dashboard.

You can see the status and details of your job under Build History. You can also click on Console Output to see the logs of your job.

You can verify that your app is running by going to your browser and typing http://localhost:8000. You should see a todo app where you can add, edit, and delete tasks.
