Getting Started

Installing OPS

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

If that works you can try this simple hello world example. You don't need Node installed for this as ops will automatically download a Node package for you:

$ ops pkg load eyberg/node:20.5.0 -p 8083 -f -n -a hi.js -m 256

Note: We have a list of pre-made Node packages on the repo if you are looking for a different version or need a different architecture (eg: arm64 for Macs).

Put this in your hi.js:

var http = require('http');
http.createServer(function (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/');

If the script complains about missing Homebrew on Mac, please install it from https://brew.sh/ and re-run the command above.

On Linux and Mac ensure that you have QEMU version 2.5 or greater installed. The latest QEMU version is 10.2 so if you are using something older - it's really old.

Debian / Ubuntu (apt-get)

To install QEMU, run

$ sudo apt-get install qemu-kvm qemu-utils

Fedora (dnf/yum)

$ sudo dnf update
$ sudo dnf install qemu-kvm qemu-img

Or:

$ sudo yum update
$ sudo yum install qemu-kvm qemu-img

macOS (brew)

$ brew install qemu

Verify the OPS Installation

$ ops version

Note: During the installation $PATH will be configured, and already opened shell windows may not be updated with these $PATH modifications until the console is restarted or the user has logged out and in again.

If running ops version in the console fails, try source ~/.bash_profile or open a new terminal.
