Quick Start

  1. git clone git@github.com:paritytech/parity-portal-hq.git && cd parity-portal-hq

  2. Run the following command, which will run the docker compose configuration from the docker-compose-demo.yml file, which uses paritytech/polkadot-hub-app/hqapp:latest image. This runs a demo app with preset configuration.

     DATABASE_URI=postgresql://test:test@postgres/test \
 JWT_SECRET=very-secret \
 PORT=3000 \
 APP_HOST=http://localhost:3000 \
 NODE_ENV=production \
 bash ./start.sh --demo

  3. Go to http://localhost:3000

1. Prerequisites

The quickest and easiest way to run Polkadot Hub App is using Docker. You can find Docker installation instructions here.

If you don't want to use Docker you can run the project from source.

2. Run the project

Quick configure

  1. cp .example.env .env

    Main variables to set: DATABASE_URI, JWT_SECRET, PORT, APP_HOST, and SUPERUSERS

  2. cp config-default config

    Your project configuration folder. Adjust to your needs. Todo: add link to configuration explanation doc

Docker

docker compose -f docker-compose.yml up

or use the start script (does exactly the same)

bash start.sh

Check Docker Application logs

docker-compose logs -f app

Check Docker Database logs

docker-compose logs -f postgres

Run From Source

Make sure to set DATABASE_URI in .env

yarn && yarn migrations:up && yarn production:run

3. Configuration

3.1 Database

3.1.1 Credentials

The current database credentials are set to sample credentials inside docker-compose.yml file. Change them to secure credentials.

It is important to create a separate database user to interact with your database and not leave it to the default user with maximum privileges.

3.1.2 Local data location

Your postgres database will persist its state between container restarts. It is mapped to a local ./postgres_data directory. The postgres_data directory will be in the same directory where you run docker compose from.

You can change this folder by editing docker-compose.yml file and specify your own local directory instead of ./postgres_data. Look for the line with ./postgres_data:/var/lib/postgresql/data

3.1.3 Remote database

If you already have your own database setup you can just set DATABASE_URI to point to your database inside .env file and pull the latest image.

DATABASE_URI=postgresql://postgresuser:postgrespassword@host/postgresdatabasename

Then run Docker like this:

docker run ghcr.io/piggydoughnut/hqapp:latest

4. Development

4.1 Building Source with Docker

To use the current source code instead of the published image, use docker-compose-dev.yml.

docker compose -f docker-compose-dev.yml build --no-cache

bash start.sh --dev

4.2 Building source with hot reload

yarn && yarn migrations:up && yarn hotreload

4.3 Publish new Docker version

  1. Build the image using Dockerfile

    docker build ./ --no-cache -t ghcr.io/username/containername:v-[VERSION_NUMBER] -t ghcr.io/username/containername:latest

  2. Login to the Github Container Registry. Creating a personal access token(classic)

    docker login --username your-user-name --password your-github-token ghcr.io

  3. Push the image with its tags

    docker push ghcr.io/username/containername:latest

docker push ghcr.io/username/containername:v-[VERSION_NUMBER]

Common Issues

SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:5432

Make sure your .env file as a correct DATABASE_URI path. The variables in the .env file prevail over manually specified env vars in the terminal.
