Node Overview

Secure your stack with a hardened Node image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Node.js is a JavaScript runtime used to run JavaScript code on the server side to build scalable network applications.

Try It Out

To take the Minimus Node image for a test run, we will create a simple web application with some JavaScript and run it with our Minimus Node container.

In your project directory, save the following JavaScript code in a file named hello-minimus-node.js:

const http = require('node:http');

const listener = (req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/html' });
  res.end(`
    <!DOCTYPE html>
    <html>
    <head>
      <title>Minimus Node Server</title>
      <style>
        body {
          margin: 0;
          padding: 0;
          background-color: #ffffff;
          font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
          display: flex;
          justify-content: center;
          align-items: center;
          height: 100vh;
        }
        h1 {
          font-size: 72px;
          color: #4285f4;
          text-align: center;
          text-shadow: 1px 1px 2px rgba(0, 0, 0, 0.1);
        }
      </style>
    </head>
    <body>
      <h1>Hello from Minimus Node</h1>
    </body>
    </html>
  `);
};

const server = http.createServer(listener);
server.listen(3000);

console.log('Server running at http://127.0.0.1:3000/');

Next, run the container and mount your JavaScript:

docker run -p 3000:3000 -d --name minimus-node \
    -v $(pwd)/hello-minimus-node.js:/home/hello_world/hello-minimus-node.js \
    reg.mini.dev/node \
    /home/hello_world/hello-minimus-node.js

Visit the landing page at http://localhost:3000. It should say "Hello from Minimus Node". If you're working in a VM, run curl ifconfig.me to look up your external IP and substitute it like this: http://{IP}:3000.

Technical Considerations

The Node image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Node built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks. The public image runs as root.
The image default working directory is /app. The public image working directory defaults to the root directory.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
