You can evaluate EDB CloudNativePG Cluster for free as part of a trial subscription. You need a valid EDB subscription to use EDB CloudNativePG Cluster in production.

Note

Based on the Operator Capability Levels model , users can expect a "Level V - Auto Pilot" set of capabilities from the EDB CloudNativePG Cluster Operator.

Long Term Support#

EDB is committed to declaring a Long Term Support (LTS) version of EDB Postgres for Kubernetes annually. 1.22 is the current LTS version. 1.18 was our first. Each LTS version will receive maintenance releases and be supported for an additional 12 months beyond the last community release of CloudNativePG for the same version.

For example, the 1.22 release of CloudNativePG will reach End-of-Life on July 24, 2024, for the open source community. Because it was declared an LTS version of EDB CloudNativePG Cluster, it will be supported for an additional 12 months, until July 24, 2025.

In addition, customers will always have at least 6 months to move between LTS versions. This means a new LTS version will be available by January 24, 2025 at the latest.

While we encourage customers to regularly upgrade to the latest version of the operator to take advantage of new features, having LTS versions allows customers desiring additional stability to stay on the same version for 12-18 months before upgrading.

Licensing#

EDB CloudNativePG Cluster works with both PostgreSQL, EDB Postgres Extended and EDB Postgres Advanced server, and is available under the EDB Limited Use License .

You can evaluate EDB CloudNativePG Cluster for free as part of a trial subscription. You need a valid EDB subscription to use EDB CloudNativePG Cluster in production.

Supported releases and Kubernetes distributions#

For a list of the minor releases of EDB CloudNativePG Cluster that are supported by EDB, please refer to the Platform Compatibility

page. Here you can also find which Kubernetes distributions and versions are supported for each of them and the EOL dates.

Multiple architectures#

The EDB CloudNativePG Cluster Operator container images support the multi-arch format for the following platforms: linux/amd64 , linux/arm64 , linux/ppc64le , linux/s390x .

Warning

EDB CloudNativePG Cluster requires that all nodes in a Kubernetes cluster have the same CPU architecture, thus a hybrid CPU architecture Kubernetes cluster is not supported. Additionally, EDB supports linux/ppc64le and linux/s390x architectures on OpenShift only.

Supported Postgres versions#

The following versions of Postgres are currently supported:

  • PostgreSQL: 12 - 17

  • EDB Postgres Advanced: 12 - 16

  • EDB Postgres Extended: 12 - 16

PostgreSQL and EDB Postgres Advanced are available on the following platforms: linux/amd64 , linux/ppc64le , linux/s390x . \ In addition, PostgreSQL is also supported on linux/arm64 . \ EDB Postgres Extended is supported only on linux/amd64 . \ EDB supports operand images for linux/ppc64le and linux/s390x architectures on OpenShift only.

About this guide#

Follow the instructions in the Quickstart to test EDB CloudNativePG Cluster on a local Kubernetes cluster using Kind, or Minikube.
