Overview

Engula Operator

The engula operator manages engula clusters deployed to Kubernetes and automates tasks related to operating an engula cluster.

Background

engula is a serverless storage engine that empowers engineers to build reliable and cost-effective databases. But it is hard to deploy it to Kubernetes since the dependency order of engula is complex.

This project is to provide a declarative way to manage engula clusters on Kubernetes easily.

Please refer to engula/engula#214 for more details.

Design

kube-rs will be used to manage 6 CRDs:

  • Cluster
  • Journal
  • Storage
  • Background
  • KernelService
  • Engine

Cluster is the high-level CRD. End users just need to create or update this CRD in most cases. The Cluster owns the underlying CRDs like Journal and so on.
