estebanandres/hellojavas repository overview

⁠JavaScript

⁠Description

A simple JavaScript application demonstrating an HTTP server that responds with "hello world."

⁠Prerequisites

Docker must be installed. You can install Docker from docker.com⁠

⁠Installation

⁠Step 1: Pull the Image

First, pull the image from Docker Hub using the following command:

docker pull estebanandres/hellojavas

⁠Step 2: Run the Container

To run the container, use the following command:

 docker run -p 8082:8082 estebanandres/hellojavas

• -p 8082:8082 maps port 8082 from the container to port 8082 on your machine.

⁠Important

To use the previous command, port 8087 must be available. If it's in use, you can map it to another port. For example, to map to port 3000, use the following command:

docker run -p 3000:8082 estebanandres/hellojavas

⁠Running the Container in the Background (Detached Mode)

If you want to run the container in the background, use the -d flag for detached mode:

docker run -d -p 8082:8082 estebanandres/hellojavas

The -d flag runs the container in the background, allowing you to continue using your terminal while the container runs. You can verify that the container is running in the background by using:

docker ps

This command will show you a list of all running containers.
