Rust (Leptos + Trunk) HTTP Server

This guide shows how to deploy a Rust HTTP server using Trunk and Leptos on Unikraft Cloud. To run it, follow these steps:

1. Install the unikraft CLI. You need a BuildKit builder. The easiest way to get one is via Docker. Alternatively, you can also directly set up and use BuildKit, see the quick start.

2. Clone the examples repository and cd into the examples/httpserver-rust-trunkrs-leptos/ directory:

   Code
   git clone https://github.com/unikraft-cloud/examples
   cd examples/httpserver-rust-trunkrs-leptos/

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

Code
unikraft login

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

Code
unikraft build . --output <my-org>/httpserver-rust-trunkrs-leptos:latest
unikraft run --metro fra \
  -m 256M \
  -p 443:8080/tls+http \
  --scale-to-zero policy=on,cooldown-time=1000 \
  --image <my-org>/httpserver-rust-trunkrs-leptos:latest

The output shows the instance address and other details:

Code
metro:        fra
name:         httpserver-rust-trunkrs-leptos-n2j7k
uuid:         7b8c9d0e-1f2a-3b4c-5d6e-7f8a9b0c1d2e
state:        starting
image:        <my-org>/httpserver-rust-trunkrs-leptos
resources:
  memory:     256MiB
  vcpus:      1
service:
  uuid:       8c9d0e1f-2a3b-4c5d-6e7f-8a9b0c1d2e3f
  name:       cool-wind-by4hq7nm
  domains:
  - fqdn:     cool-wind-by4hq7nm.fra.unikraft.app
networks:
- uuid:       9d0e1f2a-3b4c-5d6e-7f8a-9b0c1d2e3f4a
  private-ip: 10.0.2.3
  mac:        12:b0:7d:4f:bc:a6
timestamps:
  created:    just now

In this case, the instance name is httpserver-rust-trunkrs-leptos-n2j7k and the address is https://cool-wind-by4hq7nm.fra.unikraft.app. They're different for each run.

The command will deploy files in the current directory.

After deploying, you can query the service using the provided URL.

To run locally:

Code
trunk serve

You can list information about the instance by running:

Code
unikraft instances list

Code
METRO  NAME                                  STATE    IMAGE                                    ARGS  MEMORY  VCPUS  FQDN                                 CREATED
fra    httpserver-rust-trunkrs-leptos-n2j7k  running  <my-org>/httpserver-rust-trunkrs-leptos        256MiB  1      cool-wind-by4hq7nm.fra.unikraft.app  2 minutes ago

When done, you can remove the instance:

Code
unikraft instances delete <instance-name>
