Cloudy CLI

What is cloudy?

Cloudy is a both an HTTP server and a CLI tool, used to run commands on a remote machine using plugins.

So what?

Well, not any commands... You write a script that exports a few functions in an object and Cloudy takes care of exposing it as an API.

Here's an example:

export default {
  greeting: {
    sayHi() {
      return 'Hello!';
    }
  }
}

And here's what the CLI can do:

cy greeting.sayHi
> Hello!

Concepts

You install the CLI locally, point it to a server and run remote commands.

On the server side, you run the same CLI, but as an HTTP API.

Getting Started

You need a machine with Node.js installed. Then you can install the Cloudy CLI and create a server.

1. Set up the server

Tip: create an alias for Cloudy CLI. Add this to ~/.profile: alias cy="npx @cloud-cli/cli"

# generate a random key
head -c 5000 /dev/urandom | sha512sum
echo '[paste-the-generated-key-here]' > key

Next, let's create a configuration file called cloudy.conf.mjs on the server:

// import your plugins
import foo from 'foo-plugin';
import { init } from '@cloud-cli/cli';

function initialize() {
  // anything you need to run when the command server starts
}

// export commands from plugins
export default { foo, [init]: initialize };

// optional, change remote port and host
export const apiPort = 1234;
export const apiHost = '0.0.0.0';

And then we start the Cloudy server:

npx @cloud-cli/cli --serve

2. Set up the local CLI

On your local machine, create a configuration file again:

// cloudy.conf.mjs
export default {};

// same port as the config on the server
export const apiPort = 1234;
export const remoteHost = 'your-server.com';
export const key = '[paste-the-generated-key-here]';

And that's it!

Now you can run npx @cloud-cli/cli --help to get a list of commands available.

How it works

• A call to cy foo.bar --option value on localhost is converted to a POST request to your-server.com/foo.bar with a JSON body { "option": "value" }.

• The server runs your command and sometimes returns an output

• The same commands can be executed with cy inside the server and in your local machine.

• And if you need to un the same but from a browser, the entire CLI is also an API
