Welcome to the world of Ops! This tool allows you to create, package, and run your applications as Nanos unikernel instances. In this guide, we will walk you through the installation process, create a “Hello World” application, and explore options for deploying to the cloud. So, roll up your sleeves and let’s get started!

1. Installation

Before firing up your Nanos unikernel, you need to install Ops. Here are the methods to do so:

Binary Installation

• Run the following command in your terminal:

sh curl https://ops.city/get.sh -sSfL | sh

Desktop Applications

You can also download desktop applications for different operating systems:

Operating System	Download
macOS	Get it on macOS
Windows	Get it on Windows

Installation via Homebrew (macOS)

• Add the repository:

brew tap nanovms/homebrew-ops

• Then install:

brew install nanovms/ops/ops

Building from Source

If you’re inclined to build Ops from source, you’ll need Go version 1.13 or greater. Here’s how:

• Install dependencies:

make deps

• Build the project:

make build

2. Your First “Hello World” Application

Now that you have Ops installed, let’s run a basic “Hello World” server. This process will showcase how unikernels operate:

First, create a file named hi.js:

const http = require('http');
http.createServer((req, res) => {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
}).listen(8083, '0.0.0.0');
console.log('Server running at http://127.0.0.1:8083');

Next, run the application using Ops:

ops pkg load eyberg node:v16.5.0 -p 8083 -n -a hi.js

Now open your browser and go to http://127.0.0.1:8083 to see the message “Hello World”.

3. Deploying to the Cloud

If you’re ready to take your application to the cloud, Ops streamlines this process without the complexities of orchestration platforms like Kubernetes. You can deploy your app to various cloud providers:

• Azure
• AWS
• Google Cloud
• Digital Ocean

Troubleshooting and Support

If you encounter any issues running your application, consider the following troubleshooting steps:

• Ensure your Ops version is up to date by running ops version.
• For details about specific environments, check the respective cloud documentation.
• Consult the community on forums or GitHub for additional support.
