Remix HTTP Server

This guide shows how to deploy a Remix app.

To do so, 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-node21-remix/ directory:

Code
git clone https://github.com/unikraft-cloud/examples
cd examples/httpserver-node21-remix/

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

In this case, the instance name is httpserver-node21-remix-jvj6b and the address is https://long-star-1tms9h1z.fra.unikraft.app. They're different for each run. You can now point your browser at the address to see your deployed instance.

You can list information about the instance by running:

Code

When done, you can remove the instance:
