Aleph-VM

Note: This project is still early prototyping.

The Aleph-VM project allows you to run programs on Aleph.im.

Programs can currently be written in Python using ASGI compatible frameworks ( FastAPI, Django, ...) and respond to HTTP requests.

Alternatively, programs written in any language can listen to HTTP requests on port 8080.

1. Writing Aleph-VM programs

Have a look at tutorials/README.md for a tutorial on how to program VMs as a user.

The rest of this document focuses on how to run an Aleph-VM node that hosts and executes the programs.

1. Quick install

To quickly install Aleph-VM on a supported Linux system for production purposes:

sudo apt update
sudo apt install -y docker.io
sudo docker run -d -p 127.0.0.1:4021:4021/tcp --restart=always --name vm-connector alephim/vm-connector:alpha
wget https://github.com/aleph-im/aleph-vm/releases/download/0.1.0/aleph-vm-0.1.0.deb
sudo apt install ./aleph-vm-0.1.0.deb

Reverse Proxy

We document how to use Caddy as a reverse proxy since it does automatic HTTPS certificates.

First, create a domain name that points to the server on IPv4 and IPv6.

This is a simple configuration. For more options, check CONFIGURE_CADDY.md.

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo apt-key add -
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

cat >/etc/caddy/Caddyfile <<EOL
