Introduction

Nutanix Database Service

Nutanix Database Service is a unique hybrid cloud-based database solution that offers support for several popular database management systems including Microsoft SQL Server, Oracle Database, PostgreSQL, MongoDB, and MySQL. With Nutanix Database Service, you can manage hundreds to thousands of databases with ease. It simplifies tasks like provisioning new databases, automating routine administrative tasks such as backups and patches, and selecting the right operating systems, database versions, and extensions to meet your specific application and compliance requirements.

Nutanix Database Service Operator

The Nutanix Database Service (NDB) Operator is an innovative tool that automates and simplifies database administration, provisioning, and life-cycle management on Kubernetes. By utilizing the NDB Operator, developers can directly provision popular database management systems like PostgreSQL, MySQL, and MongoDB from their K8s cluster with ease. This results in significant time savings that could take days to weeks of effort if done manually. The NDB Operator is an open-source tool that can be accessed from your preferred Kubernetes platform, and also allows you to benefit from the full database life-cycle management that NDB provides.

Problem Statement

Our team's first task was to get familiar with the operator's codebase which was written in GoLang. We also had to understand basic cluster administration using Kubernetes and make ourselves familiar with the Go Operator SDK which is what is used to develop custom Kubernetes Operators. Our goal was to enhance the functionality of the Nutanix Database Service (NDB) Operator, which at the time could only support the provisioning of PostgreSQL databases. We had to extend the capabilities of the operator to include the provisioning and de-provisioning of MySQL databases. This required modifications to the existing operator to enable the provisioning of MySQL databases, as well as refactoring of the operator's code-base to support this added feature. We also had to make sure that the Operator's code was tested and that the provisioning and de-provisioning steps were tested end-to-end.
