UBI-Based Images

Docker Images Based on , certified and supported by Red Hat, with the following advantages:

• Immutability: Secure and stable by design, minimizing risks from mutable layers.

• Small size: Uses UBI minimal and micro variants for faster builds, smaller images, and quicker pulls.

• Security and compliance: CVE scanning and patching ensure industry-standard compliance.

• Enterprise-grade support: Maintained and supported by Red Hat for reliable updates and long-term stability.

MariaDB Enterprise Operator 1.0.0 is a major release, providing a secure, scalable, and OpenShift-certified solution to manage MariaDB Enterprise workloads. Refer to the for detailed information.

The current release has been tested with the following versions:

Release date: 29th October 2025

We are excited to announce release of MariaDB Enterprise Operator 25.10 - delivering enterprise-grade automation for managing MariaDB Enterprise workloads on Kubernetes and Red Hat OpenShift.

If you're updaing from previous versions, please follow the UPDATE GUIDE to ensure a safe transition.

Long-Term Support (LTS) Release

With the 25.10 release, we’re introducing annual LTS releases for the Enterprise Kubernetes Operator to provide long-term stability and a predictable upgrade path. LTS releases focus on security updates and critical bug fixes and maintain CRD compatibility within the LTS release, helping teams meet SLAs and reduce operational overhead in mission-critical environments. New features will continue to ship in the rolling releases between LTS cycles, while the LTS serves as a hardened, stable baseline.

Please refer to the and documentation to start using LTS releases.

Primary/Replica Topology with Replication

The Enterprise Kubernetes Operator now enables provisioning of MariaDB primary/replica topology with MaxScale for automated failover/switchover with topology – and health-aware routing. Replicas scale on demand and can be seeded from physical backups or VolumeSnapshots, reducing day-2 toil while improving availability and read throughput. When replication errors occur, the Enterprise Kubernetes Operator automatically re-seeds the replica from the latest physical backup or VolumeSnapshot and rejoins it to the topology, cutting MTTR.

Please refer to the for more details about this topology.

MariaDB Enterprise Server

The Enterprise Kubernetes Operator now supports MariaDB Enterprise Server 11.8, which delivers security improvements, compatibility enhancements, new data types and SQL functions, performance and disk-space management, and auditing/monitoring enhancements – giving teams a stronger, more efficient engine for production with the Enterprise Kubernetes Operator.

MariaDB MaxScale

The Enterprise Kubernetes Operator also supports MariaDB MaxScale 25.10, the most current release that includes new capabilities such as a database firewall (learns safe query patterns and blocks unsafe ones), MaxGUI SSO via OpenID Connect, and NoSQL compatibility improvements.

VolumeSnapshot Lock Optimization

The Enterprise Kubernetes Operator now optimizes the locking mechanism during volume snapshot creation. With this enhancement, the lock is released immediately after the VolumeSnapshot is provisioned, eliminating potential contention during the long replication process of a snapshot by backend storage.

Support for Galera Sequence + GTID in Recovery

The Enterprise Kubernetes Operator now supports recovery of Galera clusters in mixed-topology deployments where a Galera cluster also exposes GTIDs for downstream replicas. Now the recovery process proceeds without error when the recovered position includes both the Galera sequence and a GTID.

Platform and component versions

The current release has been tested with the following versions:

Release date: 26 August 2025

We are excited to announce release of MariaDB Enterprise Operator 25.08 - delivering enterprise-grade automation for managing MariaDB Enterprise workloads on Kubernetes and Red Hat OpenShift.

If you're updaing from previous versions, please follow the UPDATE GUIDE to ensure a safe transition.

This enterprise version is based on the 25.8.3 Community release, adding support for non-blocking Physical Backups and the IBM Power (ppc64le) architecture among other enterprise-grade enhancements.

Non-Blocking Physical Backups

With the Enterprise Operator, we extend physical backups via mariadb-backup and Volume Snapshots available in Community version with support for non-blocking physical backups. By leveraging feature, backups are taken without long read locks or service interruptions. This enables consistent, production-grade backups with minimal impact on running workloads, ideal for high-availability and performance-sensitive environments.

IBM Power (ppc64le) architecture support

We’ve added support for the ppc64le architecture for Enterprise Operator, enabling deployment and management of containerized MariaDB Enterprise Server and MaxScale on IBM Power systems, including certified images with Red Hat OpenShift for ppc64le. This enhancement allows teams to standardize Kubernetes-based database operations across diverse infrastructures, including amd64, arm64, and ppc64le environments.

Compatibility with CNCF-Certified Kubernetes Distributions

We are extending our engineering policy to support the three latest Kubernetes versions across all . While validation is performed on upstream Kubernetes, support extends to certified container platforms based on CNCF conformance, including Amazon EKS, Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), VMware Tanzu Kubernetes Grid, and other CNCF-certified distributions. Infrastructure-related issues, such as misconfigured Kubernetes clusters or problems with CSI (storage) or CNI (network) drivers, remain outside the scope of support.

Validation with OpenShift 4.16 EUS version

The Enterprise Operator is now validated with OpenShift 4.16, in addition to the currently available 4.18 version. This update ensures compatibility with the two most recent OpenShift Extended Update Support (EUS) versions, allowing platform teams to deploy and manage MariaDB Enterprise Server and MaxScale while staying aligned with Red Hat’s recommended upgrade path.
