The Data API Service

Last updated 9 months ago

The first component that we need is an API service that allows our devices to communicate the work they've completed to W3bstream. This service will implement the data streaming and sequencing layers of the .

For our project, we will leverage the provided with W3bstream deploying it on a Linux server in the cloud configured with Ubuntu 24. This setup is flexible and can be hosted on any VPS or equivalent cloud service.

Step 1: Set Up Your VPS

SSH into Your VPS

Use SSH to connect to your server. Replace username with your server username and your_server_ip with the actual IP address of your server.

ssh username@your_server_ip

Update and Upgrade the System

Ensure your server is up to date with the latest security patches and updates.

sudo apt update && sudo apt upgrade -y

Step 2: Install Docker and Docker Compose

Install Docker

Verify that the Docker Engine installation is successful by running the hello-world image.

sudo docker run hello-world

Install Docker Compose

Verify Installation:

  • Check that Docker and Docker Compose are installed correctly:

docker compose version

Step 3: Configure Docker Compose

Fetch the latest W3bstream docker-compose.yaml

Fetch the latest release of docker-compose.yaml from the W3bstream repository

# Fetch the latest W3bstream release number
export RELEASE=$(curl --silent "https://api.github.com/repos/iotexproject/w3bstream/releases/latest" | jq -r .tag_name)

# Download the Risc Zero demo prover
curl -L -o test/project/10000 https://raw.githubusercontent.com/iotexproject/w3bstream/$RELEASE/docker-compose.yaml

Configure docker images

Edit docker-compose.yaml and apply the following changes:

  1. Delete or comment out all image sections except the sequencer and Postgres images

  2. Configure the Postgres database image

  3. Configure the Database settings in the sequencer image to match the Postgres configuration

The Docker Compose plugin should be installed by default. If needed, you can
