Rust HTTP Server

This guide explains how to create and deploy a Rust app. To run this example, follow these steps:

1. Install the CLI and a container runtime engine, for example Docker. Use the unikraft CLI or the legacy kraft CLI.

2. Clone the examples repository and cd into the examples/httpserver-rust1.91 directory:

Code
git clone https://github.com/unikraft-cloud/examples
cd examples/httpserver-rust1.91/

Make sure to log into Unikraft Cloud and pick a metro close to you. This guide uses fra (Frankfurt, 🇩🇪):

When done, invoke the following command to deploy this app on Unikraft Cloud:

The output shows the instance address and other details:

Code
[●] Deployed successfully!
 │
 ├────── name: httpserver-rust191-pinzf
 ├────── uuid: 8acb3d35-38ba-4929-81de-950340662c14

 ├──── memory: 384 MiB

 ├ private ip: 10.0.2.53
 └────── args: /server

In this case, the instance name is httpserver-rust191-pinzf and the address is snowy-feather-k4pfgl8t.fra.unikraft.app. They're different for each run.

Use curl to query the Unikraft Cloud instance:

Code
curl https://snowy-feather-k4pfgl8t.fra.unikraft.app

Code
Hello, World!

You can list information about the instance by running:
