OpenEverest: Open-Source Database-as-a-Service on Kubernetes
Shriira Press
Run your own database-as-a-service on any Kubernetes cluster — provision, back up, scale, and recover PostgreSQL, MySQL, and MongoDB without deep DBA or Kubernetes expertise.
Welcome to OpenEverest: Open-Source Database-as-a-Service on Kubernetes.
OpenEverest — created by Percona and contributed to the CNCF Sandbox — is an open-source platform that turns any Kubernetes cluster into a private database-as-a-service. Instead of clicking through a cloud provider's managed-database console and accepting whatever lock-in comes with it, teams can give their developers a clean web UI and API for spinning up production-grade PostgreSQL, MySQL, and MongoDB clusters, complete with high availability, scheduled backups, point-in-time recovery, and monitoring, all running on infrastructure they control. This book walks the whole stack. It opens with the problem OpenEverest solves and the shape of its solution, then descends into the architecture: the control plane, the Everest operator, and the Percona database operators it orchestrates. From there it covers the DatabaseCluster custom resource and its siblings, installation with everestctl, day-to-day provisioning, backups and recovery, scaling and high availability, observability, access control, and finally how the whole thing fits into a real platform-engineering practice. By the end you will understand not just how to drive OpenEverest, but why it is built the way it is.
