Nebulæ

Overview

Nebula is a universal tool designed for deploying and maintaining crypto nodes and auxiliary infrastructure. Inspired by the initial state of space where various planets begin to form, Nebula aims to provide a cohesive and scalable environment for setting up and managing blockchain networks and their supporting services.

Goals

• Simplify Deployment: Streamline the process of deploying crypto nodes on bare-metal or cloud-based instances.

• Automate Configuration: Automate the setup and configuration of instances with necessary dependencies.

• Kubernetes Integration: Install and manage Kubernetes clusters using K0s.

• Resource Management: Deploy initial Kubernetes resources seamlessly.

• Modular Stacks: Allow for independent deployment of crypto stacks, monitoring, and automation tools.

Architecture

Nebula’s architecture is based on a series of fundamental steps:

1. Provisioning: Setting up bare-metal or cloud-based instances.

2. Configuration: Preparing instances with the required settings and dependencies.

3. K0s Installation: Installing K0s to create a Kubernetes cluster.

4. Initial Resources Deployment: Deploying essential Kubernetes resources like ArgoCD.

5. Crypto Stacks Deployment: Deploying independent batches of crypto stacks, including monitoring and automation tools.
