Announcement

The AlloyDB Omni Kubernetes operator version 1.6.4 is generally available (GA) and adds support for AlloyDB Omni version 15.18.1 for PostgreSQL 15 clusters.

To get all the bug fixes and updates in this release, use operator 1.6.4 with database version 15.18.1.

For information about how to upgrade an existing PostgreSQL 15 cluster to database version 15.18.1, see Upgrade the AlloyDB Omni Kubernetes operator and Perform a minor database version upgrade.

Fixed

Fixed an issue where the health check prober might report a false failure status because it kept using cached client connections after an operator client certificate expired or was revoked. For more information, see Mitigate operator client certificate expiration in operator versions earlier than 1.8.2.

Fixed

Fixed an issue where audit logger pipe file descriptors might leak when the database restarted with pgaudit enabled. The leak left orphaned logger processes that might cause out-of-memory (OOM) conditions.

This fix is available only for PostgreSQL 15 clusters running database version 15.18.1 on operator 1.6.4. For more information, see Perform a minor database version upgrade.

Fixed

Updated the tzdata version 2026e time zone data in AlloyDB Omni version 15.18.1 to incorporate the 2026 IANA daylight saving time rules.

This update is available only for PostgreSQL 15 clusters running database version 15.18.1 on operator 1.6.4. If your database uses an affected time zone, see Update timestamps and indexes after you upgrade to 15.18.1.

Security

Removed the distrusted emSign ECC Root CA - G3 and AAA Certificate Services root certificate authority (CA) certificates from the operating system trust store in AlloyDB Omni version 15.18.1. The trust store now uses ca-certificates version 20250419~deb12u2. For details, see security bulletin GCP-2026-071.

This update is available only for PostgreSQL 15 clusters running database version 15.18.1 on operator 1.6.4. For more information, see Perform a minor database version upgrade.

October 30, 2026

Issue

In AlloyDB Omni Kubernetes operator versions earlier than 1.8.2, the operator doesn't reload its renewed dbs-al-cert-l2-operator mutual TLS (mTLS) client certificate into existing high availability (HA) health-check connections. Approximately 60 days after the certificate is issued, health checks might fail with a tls: expired certificate error and trigger an unplanned failover. To prevent this issue, upgrade to operator version 1.8.2 or later. Until you upgrade, rotate the dbs-al-cert-l2-operator Secret in the alloydb-omni-system namespace and restart the local-controller-manager Deployment at least 10 days before the certificate expires. For instructions, see Mitigate operator client certificate expiration in operator versions earlier than 1.8.2.

Announcement

The AlloyDB Omni Kubernetes operator version 1.9.0 is generally available (GA). Version 1.9.0 includes the following features and changes:

AlloyDB Omni provides support for the following new PostgreSQL minor versions:

Change
  • The DBCluster custom resource now supports configuring CPU and memory resource limits for PgBouncer and system control plane agents such as the logrotate agent.
  • The UserDefinedAuthentication resource now supports configuring custom pg_hba.conf entries. This lets you customize client authentication behavior, such as restricting client subnets, specifying custom authentication methods, or configuring user mapping.
  • The DBCluster custom resource now supports configuring an image pull secret for DBCluster service accounts. You can operate with private image registries to automatically pull pod images without needing to manually pre-create service accounts. For more information, see Install AlloyDB Omni using the container orchestrator.
  • The TdeConfig custom resource now supports Thales CipherTrust Manager as an external Key Management Service (KMS) provider for Transparent Data Encryption (TDE), in addition to HashiCorp Vault. For more information, see Create a TDE-enabled cluster.
  • Cross-data-center replication now supports auto-heal of standbys. For more information, see Work with cross-data-center replication.
  • The DBCluster custom resource now supports using external, non-cert-manager custom issuer kinds, for example, VenafiIssuer from the jetstack.io API group. For more information, see Configure custom issuers.
Security
Fixed

Resolved an issue where the logrotate-agent could fail or hang during high audit log volumes, such as when pgaudit.log is set to all, which could lead to logrotate-agent out-of-memory errors, unbounded log growth, and disk exhaustion. The log rotate workflow has been improved, and resource limits for sidecar containers are now configurable to prevent resource constraints. For more information about the operator's logging mechanism and supported parameters, see Configure log rotation.

Issue

After you enable cross-data-center replication, the monitoring agent might encounter permission errors when attempting to gather cgroups information. If this error occurs, delete the downstream database Pod so that the operator recreates and restarts the Pod.

Issue

The AlloyDB Omni Kubernetes operator uses cert-manager, a third-party open source component, to provision Transport Layer Security (TLS) certificates. In cert-manager version 1.21.2 and earlier, a known race condition might cause certificate issuance to fail. For more information, see Resolve certificate issuance failures in cert-manager.

October 05, 2026

Announcement

The AlloyDB Omni Kubernetes operator version 1.8.2 is now available.

Security

This release includes security fixes for the following vulnerabilities:

Fixed

Fixed an issue in the Node Manager where the -nm pods failed to schedule due to those pods not inheriting scheduling config from the instance. Node Manager is a component that lets you roll out control plane features without requiring a data plane restart or database downtime.

Fixed

Fixed a concurrent read-modify-write race condition on pg_hba.conf between control plane and data plane agents.

Fixed

Fixed an issue where the health check prober could post a false failure status because it did not hot-reload cached client connections when a certificate expired or was revoked. If you run an operator version earlier than 1.8.2, see Mitigate operator client certificate expiration in operator versions earlier than 1.8.2.

Fixed

Fixed an issue where the database failed to start due to a multiple primary key constraint for g_columnar_config in the post-startup script.

Fixed

Reliability improvement for backups from standby instances: Fixed an issue in the AlloyDB Omni Kubernetes operator version 1.7.0 where backups taken from a standby instance could be incomplete if the primary instance were under heavy load. The backup process now performs a checkpoint before starting to ensure data integrity.

Upgrade required: If you use the backup from standby feature, upgrade to the latest versions of the AlloyDB Omni control plane and data plane. After you perform the upgrade, take a new backup to make sure that your data is fully protected.

Issue

Restore operations might fail if a database backup is running at the same time. If this occurs, retry the restore operation after some delay.

September 18, 2024

Feature

The AlloyDB Omni operator is now available in Preview on Google Distributed Cloud (GDC) connected. For more information, see Install AlloyDB Omni on Kubernetes.

September 16, 2024

Breaking

The postgres_ann extension has been renamed to alloydb_scann. Before you upgrade to AlloyDB Omni Kubernetes operator version 1.1.1, you must drop any indexes created using the earlier postgres_ann version, then upgrade AlloyDB Omni, and then create the indexes again using the alloydb_scann extension.

Fixed

AlloyDB Omni Kubernetes operator version 1.1.1 is now available. This patch fixes the following issues:

  • Fixed a regression for the AlloyDB Vertex AI integration.
  • Fixed a bug in which upgrading from version 1.0.0 to version 1.1.0 failed when using injected sidecars.
  • Fixed a bug in which backups weren't reestablished correctly across failovers when using the Commvault sidecar with high availability (HA) configurations.
  • Fixed a bug that caused a status to be incorrectly set by the load balancer, resulting in erroneous reports that the database cluster wasn't ready.
Feature

Added a tutorial that shows you how to set up a connection from an application running in a Google Kubernetes Engine autopilot cluster to an AlloyDB instance.

Issue

Upgrading to version 1.1.1 of the AlloyDB Omni Kubernetes operator might result in a brief interruption to all database clusters. No data loss is expected.
