Red Hat Certification and Container Compliance for Crunchy Postgres for Kubernetes

Overview

Crunchy Postgres for Kubernetes is certified by Red Hat, ensuring it meets stringent security and compatibility standards. This certification encompasses our use of containers, specifically adhering to the "Container image requirements" set forth by Red Hat.

Container Image Requirements

According to Red Hat's guidelines, container images must use a Universal Base Image (UBI) provided by Red Hat. The version of the UBI base image must be supported on the RHEL version undergoing certification.

Compliance with UBI 8

Currently, our UBI 8 containers fully comply with Red Hat’s requirements. The Red Hat Enterprise Linux Container Compatibility Matrix confirms that UBI 8 containers are supported across all host types, including RHEL 7, RHEL 8, and RHEL 9. This means our containers are supported on both older RHEL hosts (e.g., RHEL 7 for older OpenShift versions) and newer RHEL hosts (e.g., RHEL 9 on OpenShift v4.13+).

Certification and Support

Customers can be assured that our containers are fully certified and supported on all available versions of OpenShift. Our robust testing across all supported OpenShift versions ensures any issues are identified and addressed, with Red Hat providing support as needed.

Cross-Platform Compatibility

One of the key advantages of containers is their cross-platform compatibility. Containers encapsulate applications and their dependencies into a consistent runtime environment, which can be executed on various underlying operating systems. This portability ensures that our containers can run seamlessly on different OS versions and environments, including different versions of RHEL, other Linux distributions, and even other operating systems that support container runtimes like Docker. This cross-platform capability ensures flexibility and broad compatibility for diverse deployment scenarios.
