Project Overview 📄

This application is the response to the Polkadot Collator Setup RFP

Overview

The main goal is to provide production-ready deployment for the Collator node that could work for any parachain with very few adjustments.

There are a lot of parachains in the substrate ecosystem, and each of them has its guide on how to spin up a collator node astar, datahighway, moonbeam, hydradx, oak. Most of those guides are just examples of how to start a collator for testing purposes and are not production-ready. That complicates life for those who want to manage collators for several parachains because each new parachain requires an entirely new setup. We aim to pack a common part of infrastructure and Collator node deployment into functional building blocks that could be used with any parachain and make it highly extendable and configurable for each specific case.

Every collator node has common steps to run it that do not depend on concrete parachain:

  • build
  • containerize
  • terraform infrastructure
  • deploy

All of that could be automated and templated for all existing and parachains future. Even if building and containerization are relatively simple tasks, most teams handle them in their own way, sometimes far away from IaC best practices. Unfortunately, there is still no unified way approved \ recommended by Web3 so we aim to fill this gap.

Project Details

First, we want to start from two unified Dockerfile templates for building and running collator node that suits best practices like minimal runtime, no root user, minimal port exposure, etc. Those templates could be easily extended with all required dependencies if needed.

The next step is to provide reproducible and configurable infrastructure via terraforming one of the supported clouds. In most cases, Collator nodes have similar requirements on infrastructure, but in case of special requirements, it would be pretty easy to configure terraform scripts for the needs.

Last step that requires most of the confgurability is a deployment step which would be handled by ansible scripts. We would provide unified deployment with configuration for the relay chain and common Collator parameters.

Components

  • Terraform deployment of the Collator infrastructure to the corresponding AWS and GCP clouds
  • Ansible scrips for the configurable deployment of a Collator node for different parachains

Technologies

  • Docker as virtualization for the collator node
  • Terraform as IaC for the reliable and reproducible infrastructure deployment
  • Ansible as deployment automatization tool

Ecosystem Fit

Currently, most parachains provide a setup guide on how to run the Collator on bare metal; however, it is neither automatized (hence non-reproducible) nor suits high availability standards. Our solution will provide most parachains with the out-of-the-box instrument for spinning up Collator. That would increase the reliability of the existing parachains as they may utilize reliability, high availability and scaling of Kubernetes. As well will significantly reduce the time and cost of spinning up the Collator for those who want to support several parachains
