Description

This project is a simple API that serves as an exercise to explore the Nomad API.

The API provides the following endpoint:

This endpoint starts a Nomad job and accepts the following parameters:

name (string): A unique identifier for the service to create.
url (string): The URL of the page to serve.
script (boolean): Specifies whether the url should be interpreted as a script or a page.

The endpoint performs the following actions based on the provided parameters:

If script is set to false, the url is downloaded and served as index.html.
If script is set to true, the url is downloaded, the script is executed, and its output is downloaded as index.html.

The endpoint returns the URL of the page.

curl localhost:3000/services -X POST -d '{"name": "my-page", "url": "https://example.com/mypage.html", "script": false}'

Response:

{
    "url": "http://192.168.1.104:27510"
}

Assuming https://example.com/mypage.html contains the following content:

Hello World!

Then the output of curl http://192.168.1.104:27510 will be:

Hello World!

curl localhost:3000/services -X POST -d '{"name": "my-page", "url": "https://example.com/myscript.sh", "script": true}'

Response:

{
    "url": "http://192.168.1.104:27511"
}

Assuming https://example.com/myscript.sh contains the following content:

#!/bin/sh

echo Hello World!

Then the output of curl http://192.168.1.104:27511 will be:

Hello World!
