Copy page

This guide shows how to deploy a Solid Start app. To do so, follow these steps:

1. Install the kraft CLI tool and a container runtime engine, for example Docker.

2. Clone the examples repository and cd into the examples/node21-solid-start/ directory:

Code
 
git clone https://github.com/kraftcloud/examples
cd examples/node21-solid-start/

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

Code
 
# Set Unikraft Cloud access token
export UKC_TOKEN=token
# Set metro to Frankfurt, DE
export UKC_METRO=fra

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

Code
 
kraft cloud deploy -p 443:3000 -M 256 .

The output shows the instance address and other details:

Code
 
[●] Deployed successfully!

 ├──── private ip: 172.16.6.8
 └────────── args: /usr/bin/node /usr/src/server/index.mjs

In this case, the instance name is node21-solid-start-lvoa2 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
 
kraft cloud instance list

Code
 
NAME                      FQDN                                STATE    CREATED AT      IMAGE          MEMORY   ARGS                              BOOT TIME

When done, you can remove the instance:

Code
 
kraft cloud instance remove node21-solid-start-lvoa2

Customize your app

To customize the app, update the files in the repository, listed below:

• Kraftfile: the Unikraft Cloud specification
• Dockerfile: the Docker-specified app filesystem
• src/: server source files
