What

This repository contains a dockerized Aleph network of 4 validators and a separate container running polkadot-js-app.

Why

To faciliate and speed-up development and end-to-end testing process.

How

Prerequisites

To start, make sure you have installed:

• docker
• docker compose
• Rust

Seting up repositories

1. make setup-submodules to clone Aleph node repository as git submodule and update it.
2. make update-aleph-node updates Aleph's git submodule. Update it whenever you want to use latest version of Aleph.

Building Docker image

make build-aleph-image builds a Docker image that containerizes a network of four Aleph nodes. We're running a whole network of nodes within a single container, rather than via docker compose up --scale 4 as that allows us for easier control over nodes' configuration.

Running Aleph network

make run-aleph-network runs a container that uses previously-built Docker image. If you want, you can interact with the exposed ports directly:

• 30334 for node's p2p endpoint
• 9944 for websocket
• 9933 for RPC

Running Aleph network with polkadot-js-app

In the root directory of the project, type docker compose up to run an Aleph network and a container with polkadot-js-app. Under localhost:80 you will now find a polkadot-js-app attached to the Aleph network running in the first container.
