Crunchy Postgres for Kubernetes is developed with many years of production experience in automating Postgres management on Kubernetes, providing a seamless cloud native Postgres solution to keep your data always available.
Crunchy Postgres for Kubernetes is designed to provide production ready Kubernetes-native Postgres clusters using a few key components:
- PGO, the Postgres Operator from Crunchy Data, is the brains behind Crunchy Postgres for Kubernetes enabling users to interact with their Postgres clusters through PGO. To accomplish this, PGO extends Kubernetes to provide a higher-level abstraction for rapid creation and management of PostgreSQL clusters by leveraging "Custom Resources" to create several custom resource definitions (CRDs) that allow for the management of PostgreSQL clusters. PGO itself runs as a Deployment and is composed of a single container.
- Crunchy Postgres, Crunchy Data's open source distribution of Postgres, along with leading Postgres tools and extensions such as pgbackrest, Patroni, pgaudit, PostGIS, and more. Each of the components within Crunchy Postgres are built with upstream source code and compiled, tested and certified by Crunchy Data. These components are provided as a series of containers via the Crunchy Data access and developer portals.
- The Crunchy Postgres for Kubernetes monitoring stack, a fully integrated solution for monitoring and visualizing key metrics pertaining to your Postgres databases, as well the containers they run within. Built on industry standards for monitoring and metrics collection, the Crunchy Postgres for Kubernetes monitoring stack ensures you have the real-time insights needed to keep all of your Postgres databases running smoothly and efficiently.
- Installers for Kustomize, Helm and OLM, providing flexibility to seamlessly and easily install and deploy Postgres clusters regardless of your specific Kubernetes distribution, or your preferred tooling for deploying to Kubernetes.
