Node.js and Python

Containerized Node.js and Python applications can be created and managed in HiTechCloud Enterprise Edition.

Create an Application​

To create a new Python or Node.js application, navigate to HiTechCloud > AutoInstaller and select Python or NodeJS.

On the next page, you can configure the following settings:

• Name – The name of the application and container as displayed in HiTechCloud.
• Port – Set a custom port (e.g., 3000 or 5000) if your app uses one. Otherwise, port 80 is used by default.
• Domain Name / Subfolder – The domain (and optional subfolder) where the application will be publicly accessible.
• Startup File – The file executed at startup with the node or py command.
• Custom Startup Command – Use a custom startup command instead of the default node or py.
• Type – Choose between Node.js or Python.
• Version – Select any available version from Docker Hub.
• Run Install – Run npm install or pip install before starting the application.
• CPU Cores – Number of CPU cores allocated to the application.
• Memory – Amount of memory (in GB) allocated to the application.

After completing the form, click Start Installation. The installation process will be displayed below the form. Once complete, you’ll be redirected to the management page where you can view all your applications.

NodeJS Example App​

An example NodeJS (express) application that is running on http://nodejs.hitechcloud.org/

Example settings:

Example app.js file:

const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello World from Node.js on port 3000!');
});

app.listen(port, () => {
  console.log(`Server is running at http://localhost:${port}`);
});

Example package.json file:

{
  "name": "helloworld-node",
  "version": "1.0.0",
  "description": "Simple Node.js Hello World app using Express",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "author": "Your Name",
  "license": "MIT",
  "dependencies": {
    "express": "^4.18.2"
  }
}

Python Example App​

An example Python (Flask) application that is running on http://python.hitechcloud.org/

Example settings:

Example app.py file:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
    return "Hello World from Flask on port 5000!"

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

Example requirements.txt file:

Flask==2.3.3

Manage Applications​

Once your application is created, you can manage it from HiTechCloud > Site Manager.

Click Manage next to the application name to open its management page.

On this page, you can view important details such as:

• Screenshot – Preview of the application’s domain.
• Status – Current container status.
• Version – Node.js or Python version in use.
• CPU Limit – Configured CPU allocation.
• Memory Limit – Configured memory allocation.
• Speed – Google PageSpeed Insights data for the website.
• Files – Current folder path and size.
• Firewall – WAF (Web Application Firewall) status for the domain (if enabled).

You also have several management options:

• Actions – Start, stop, or restart the container.
• Overview – Modify startup file or command, working directory, package installation settings (NPM/PIP), version, and resource limits (CPU, Memory, PIDs).
• Install Packages – View and manage package.json or requirements.txt, and run NPM/PNPM or PIP installations.
• Logs – View container logs for troubleshooting.
• Remove – Delete the application.
