Clarification on Red Hat OpenShift support for Kubernetes

Here it specifically mentions PostgreSQL database

Are other databases supported? Or is PostgreSQL the only supported DB in this configuration?

We can confirm that PostgreSQL is indeed the only officially supported database for Pega Platform deployments on Red Hat OpenShift container platform.

In the documentation you referenced (Deploying Pega on OpenShift), PostgreSQL is specifically mentioned as the database to use with this configuration. This is consistent across Pega’s official documentation sources. When examining the Pega Platform Support Guide and other technical documentation, PostgreSQL is consistently identified as the primary relational database option for Red Hat OpenShift deployments.

For Kubernetes container services like Red Hat OpenShift, Pega recommends using the following database pairings:

  • Red Hat OpenShift → PostgreSQL
  • Amazon EKS → Amazon RDS for Postgres
  • Google GKE → Cloud SQL for PostgreSQL
  • Azure AKS → Azure Database for Postgres

While Pega Platform generally supports other database types (like Oracle, Microsoft SQL Server, and IBM DB2) in different deployment scenarios, the Red Hat OpenShift deployment model is specifically designed and tested with PostgreSQL. Using other database types with OpenShift deployments would be outside the officially supported configuration.

If you have specific requirements that make PostgreSQL challenging for your implementation, I’d recommend reaching out to Pega Support for guidance on potential alternatives or customizations that might be possible for your particular use case.

Hi Donald,

Although the Pega helm charts github documentation uses PostgreSQL DB to showcase the readme for the deployments, Pega Platform supports all the relational databases (as per the attached image) as mentioned in the Platform Support Guide

If you are using Customer Decision Hub, then it has a narrower and more specialized list of supported platforms. In the case of using CDH, Red Hat Openshift supports only PostgreSQL DB. Ref 3rd point in the above image. See Deployment requirements for client-managed cloud for more details.

I hope this clarifies your query.
