Automated Web Deployment and Monitoring Project

A simple static website deployment with Continuous Integration, Continuous Deployment, Testing and Monitoring All-in-one (Using Jenkins, Docker, Git , Python, Loki and Grafana)

Usage

1. Version Control (GitHub):

1. Create a GitHub Repository:
   • Create a new GitHub repository to host your web application code.
   • Push your web application code (HTML, CSS, JavaScript) to this repository.

2. Continuous Integration (CI) with Jenkins:

1. Set Up Jenkins:
   • Install and configure Jenkins on a server or a cloud-based machine.
   • Install necessary plugins such as Git, Docker, and any additional plugins you may need.
2. Create a Jenkins Job:
   • Create a new Jenkins job for your web application CI process.
   • Configure the job to pull code from your GitHub repository.
3. Build and Test:
   • In your Jenkins job configuration, define build steps to:
     • Clone the repository.
     • Build the web application (e.g., copying files to a build directory).
     • Run basic tests (e.g., HTML/CSS validation) using relevant tools (e.g., HTML Validator, CSSLint).
     • Archive build artifacts (e.g., ZIP or tar.gz files).
4. Configure Post-Build Actions:
   • In Jenkins, configure post-build actions to archive and publish the build artifacts.
   • Optionally, trigger deployments to specific environments if all tests pass.

3. Continuous Deployment (CD) with Docker:

1. Create a Dockerfile:
   • In your web application code repository, create a Dockerfile to define how your application should be packaged into a Docker container.
   • Install a simple web server like Nginx to serve your static website.
2. Automate Docker Build:
   • Configure your CI/CD pipeline to automatically build a Docker image whenever changes are pushed to the main branch.
   • Push the Docker image to a container registry (e.g., Docker Hub).
3. Deploy with Docker:
   • Deploy the Docker container to a simple web server (e.g., AWS EC2, DigitalOcean Droplet) or cloud storage (e.g., AWS S3) whenever changes are pushed to the main branch.
   • Use a deployment script or a CI/CD tool's deployment functionality to automate this process.

4. Monitoring with Loki and Grafana:

1. Install Loki and Grafana:
   • Set up Loki, a log aggregation system, and Grafana, a monitoring and visualization platform, on your server or a cloud-based instance.
2. Configure Logging:
   • In your web application and deployment scripts, incorporate logging statements.
   • Configure your web server (e.g., Nginx) to log access and error information.
3. Integrate Loki and Grafana:
   • Configure your applications and deployment scripts to send logs to Loki.
   • Set up Grafana dashboards to visualize and analyze logs and deployment metrics.
   • Grafana can be configured to query logs from Loki and display them in a user-friendly way.
4. Alerting (Optional):
   • Configure alerts in Grafana to notify you of specific events or issues, such as deployment failures or abnormal application behavior.

5. Final Steps:

1. Test Your CI/CD Pipeline:
   • Push changes to your GitHub repository's main branch and observe the Jenkins CI/CD pipeline in action.
   • Monitor the logs and metrics in Grafana to ensure everything is functioning as expected.
2. Documentation:
   • Document your CI/CD pipeline setup, including GitHub repository, Jenkins job configurations, Dockerfile, and Loki/Grafana setup.
   • This documentation will help your team understand and maintain the pipeline.
3. Ongoing Maintenance:
   • Regularly review and update your CI/CD pipeline as your web application evolves.
   • Monitor and fine-tune your Loki and Grafana configurations to meet your monitoring needs.
