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 node_v14.2.0 -p 8083 -f -n -a hi.js

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 complain about missing HomeBrew on Mac, please install it from https://brew.sh/ and re-run the command above.

On Linux flavors ensure that you have QEMU version 2.5 or greater installed. It should be noted that the latest qemu version is 6.1 so if you are using something older - it's really old.

Debian / Ubuntu (apt-get)

To install QEMU, run the following command:

$ 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

Verify the OPS Installation

$ ops version

Note: During the installation setup the PATH will be configured, and already open command 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.
