🐳 docker_node

A beginner-friendly, Ubuntu-based Docker image preloaded with:

• 🟢 Node.js 22.x (via NodeSource)
• ✏️ Nano text editor
• 🔗 Git for version control

Perfect for learning, prototyping, and developing in a clean CLI-based Node.js environment.

💡 What is This?

This repository contains a Dockerfile — a recipe that builds a virtual machine-like environment using Docker. It’s great for:

• Trying out Node.js without installing it locally
• Creating a clean dev space with nano and git
• Learning Docker in a no-stress, no-frills way

This is NOT the official docker-node image, head to docker-node instead for that one, this version is just a personal project designed to be beginner-friendly, with Git and Nano pre-installed and a simple, easy-to-understand setup. Great for those who want to quickly dive into Docker and Node.js without worrying about configuring everything from scratch. It’s heavier than standard Node images (~440MB), but trades performance for ease of use and familiar tooling.

🚀 Getting Started

⚙️ 1. Prerequisites

• 🐳 Install Docker
• 💻 Use terminal/bash (on Linux/macOS) or PowerShell (on Windows)

---

🧱 2. Clone This Repo

git clone https://github.com/bsmaceira/docker_node.git
cd docker_node

---

🔧 3. Build the Docker Image

docker build -t docker_node:1.0 .

This reads the Dockerfile and builds your image locally.

---

🧑‍💻 4. Run the Container

docker run -it --hostname docker-node docker_node:1.0

Now you’re inside your custom Ubuntu container, with Node.js and tools ready!

🙋 FAQ

Q: Can I install more tools later?
✅ Yes — use apt install <tool> inside the container.

Q: Do my changes persist between container sessions?
🚫 By default, no. Use Docker volumes or commit changes to a new image.

Q: Can I turn this into a full web server?
🧱 Absolutely! Install express, map ports, and start building.

🛠️ Want to Customize?

You can modify the Dockerfile to:

• Add libraries like Express, MongoDB, etc.
• Include VS Code Server for browser-based coding
• Automatically install packages on build
