Python Flask App with Docker and GitLab CI/CD Pipeline

This project demonstrates containerization of a Python Flask application using Docker and automation of the build pipeline using GitLab CI/CD.

---

Features

• Containerization of a Python Flask app using Docker.
• Automated build pipeline using GitLab CI/CD.
• Organized multi-stage pipeline (Build and Test).

---

Technologies Used

• Docker: For creating lightweight, portable containers.
• GitLab CI/CD: For pipeline automation.
• Python (Flask): As the sample application framework.

---

Getting Started

Prerequisites

• Docker installed on your system.

---

Steps to Run Locally

1. Clone this repository:

   git clone https://github.com/<your-username>/<repo-name>.git
   cd <repo-name>
   

2. Build the Docker image:

   docker build -t python-app 
   

3. Run the container:

   docker run -p 5000:5000 python-app
   

4. Access the application:

   Open your browser and navigate to http://localhost:5000.

CI/CD Pipeline Workflow

The GitLab CI/CD pipeline automates the following stages:

Build: Builds the Docker image for the Flask app.
Test (Optional): Runs unit tests(NIL for Now)
