What's New in Crunchy PostgreSQL Operator 4.0

Jeff McCormick
PostgreSQL Kubernetes Containers

Crunchy Data is pleased to release PostgreSQL Operator 4.0.

Crunchy PostgreSQL Operator extends Kubernetes to give you the power to easily  create, configure and manage PostgreSQL clusters at scale.  When combined with the Crunchy PostgreSQL Container Suite, the Crunchy PostgreSQL Operator provides an open source software solution for PostgreSQL scaling, high-availability, disaster recovery, monitoring, and more.  All of this capability comes with the repeatability and automation that comes from Operators on Kubernetes.

Crunchy PostgreSQL Operator is open source and developed in close collaboration with users to support enterprise deployments of cloud agnostic PostgreSQL-as-a-Service capability.  This release comes after extensive feedback from our customers and the community to ensure the scalability and security that sysadmins, DBAs, and developers have come to rely on.


Key features added to the Crunchy PostgreSQL Operator 4.0. include:

Namespace Deployment Options

Support for deploying the Crunchy PostgreSQL Operator with additional namespace patterns, including the ability to deploy the operator its own namespace but manage PostgreSQL clusters in multiple namespace. The new namespace management features lets users create multi-tenant PostgreSQL environments that add further isolation and security to their deployments. The various deployment patterns are included within the Design documentation.

Further Enhancements to pgBackRest Integration

Crunchy PostgreSQL Operator 4.0. continues the integration of pgBackRest, building on features incorporated within version 3.5.  For example, this latest release adds the ability to perform pgBackRest backups to Amazon S3. This allows  users to create an automated, geographically distributed, and hybrid cloud disaster recovery strategy: : in addition to the benefits of backing up to a distributed object store, users can move their PostgreSQL data easily between data centers.

Integrated PostgreSQL Benchmarking

Crunchy PostgreSQL Operator 4.0. adds the ability to run pgBench, a simple program for running standard and customizable benchmark tests on PostgreSQL, from the Operator command-line interface. The operator CLI overview documentation provides guidance as to how to use this capability. This provides and simple and easy means for users to compare and investigate performance and scalability under different deployment scenarios.

Ansible Playbook Based Installation

Crunchy PostgreSQL Operator 4.0 provides Ansible playbooks to automate operator installation. The Crunchy PostgreSQL Operator Ansible Installers allow users to install PostgreSQL Operator on Kubernetes and OpenShift from a Linux, Mac or Windows (Ubuntu subsystem) host.  In connection with the automated installation, the Ansible playbooks can generate TLS certificates required by the PostgreSQL Operator and configure PostgreSQL Operator settings from a single inventory file.

Operator Lifecycle Management (OLM)

Crunchy PostgreSQL Operator 4.0. supports Operator Lifecycle Management (OLM). The OLM project is a component of the Operator Framework, an open source toolkit to manage Operators, in an effective, automated, and scalable way. OLM concepts were included into Crunchy PostgreSQL Operator to assist in the deployment on Kubernetes using OLM integration.
