Docker Basics in Node.js

This repository serves as a practical demonstration of various DevOps concepts, focusing on Docker, Node.js, TypeScript, and Continuous Integration/Continuous Deployment (CI/CD) pipelines using GitHub Actions.

Overview

In this project, we cover the following topics:

Docker: Docker is utilized to containerize our Node.js application, ensuring consistency and portability across different environments. We create a Docker image to encapsulate our application and its dependencies.
Node.js with TypeScript: Our application is built using Node.js, a popular JavaScript runtime, along with TypeScript, which adds static typing to the language, enhancing code quality and developer productivity.
Database Integration: Our Node.js application interacts with a database, demonstrating how Docker can be used to manage complex development environments with multiple interconnected components.
Volumes: Docker volumes are employed to persist data, ensuring that database changes are retained even when containers are destroyed and recreated.
GitHub Actions for CI/CD: We implement Continuous Integration (CI) and Continuous Deployment (CD) pipelines using GitHub Actions. With every commit, a new Docker image is built and pushed to GitHub's container registry, facilitating automated testing and deployment workflows.

Getting Started

To run the project locally, follow these steps:

Clone the Repository:

git clone https://github.com/Naveen-g09/Docker-Basics-in-Nodejs.git

Navigate to Source Directory:
```
cd Docker-Basics-in-Nodejs/src
```
Install Dependencies:
```
npm install
```
Start the Server:
```
npm run pm2
npm run start
```

This will launch the Node.js server locally.

Creating a Docker Image

To create a Docker image from the project, follow these steps:

Navigate to the Root Directory of the project.
Build the Docker Image:
```
docker build -t <image_name> .
```
Commit Changes and Push to GitHub: After building the Docker image locally, commit your changes and push them to GitHub. This will trigger the CI/CD pipeline configured with GitHub Actions, automatically building and pushing the Docker image to the GitHub container registry.
