Bitnami chart usage after recent change of image repository

Context

The GitLab Helm chart default configuration relies on Bitnami charts and container images for PostgreSQL and Redis. Bitnami will discontinue these images from their free catalogs on September 29th, 2025. Brownouts taking down images temporarily started on August 28th, 2025.

GitLab chart bundles Bitnami’s PostgreSQL and Redis for demo and testing purposes only. They are not part of any supported GitLab reference architecture. If you are on a reference architecture or deployed an external PostgreSQL and Redis with another vendor’s packages or images, you are not impacted by this change.

As a temporary solution, GitLab has migrated the chart configuration to the Bitnami legacy repository. However, unpatched GitLab chart environments (GitLab 17.11, GitLab 18.0.5. GitLab 18.1.4, and GitLab 18.2.1 or earlier) will continue to pull images from the deprecated Bitnami repository, which will cause deployment failures after September 29th and may cause deployment failures during the brownout phase.

If you’re running an affected GitLab chart configuration, you must do one of the following:

• Migrate to a supported GitLab reference architecture.
• Upgrade to a patched chart version.
• Configure the legacy repository in your chart values. For an example, see merge request 4421.
