Replace restricted Bitnami PostgreSQL HA image in Gitea chart to ensure reliable platform deployments

[igor-soldev]

Hi,

I was reviewing the App Platform components and noticed that the embedded Gitea sub-chart for PostgreSQL High Availability (charts/gitea/charts/postgresql-ha) relies on the bitnami/postgresql-repmgr Docker image.

The Problem
Bitnami has recently restricted public access to their Docker images, placing them behind a paywall with strict rate limits. Relying on the bitnami/postgresql-repmgr namespace now frequently results in pull access denied errors. For a core platform offering like App Platform on Linode Kubernetes Engine, these access restrictions pose a significant risk of failing automated cluster provisioning, breaking updates for users, and degrading the "out of the box" installation experience.

Proposed Solution
I suggest switching to soldevelo/postgresql-repmgr.
This image is a free, actively maintained, and fully open-source fork of the original Bitnami image.

Crucially, it is a drop-in replacement:

• It preserves the exact same environment variables used for repmgr clustering and failover logic.
• It maintains the same internal paths and volume mounts (e.g., /bitnami/postgresql).
• Your existing Helm chart values (charts/gitea/charts/postgresql-ha/values.yaml) and deployment scripts will continue to work immediately without requiring any refactoring.

(Note: SolDevelo maintains a growing library of open-source, Bitnami-compatible images to help the community bypass these new restrictions. You can find the source code and other images here: https://github.com/SolDevelo/containers)

Suggested Changes:

In charts/gitea/charts/postgresql-ha/Chart.yaml:

# Old
- name: postgresql-repmgr
  image: docker.io/bitnami/postgresql-repmgr:17.6.0-debian-12-r2

# New
- name: postgresql-repmgr
  image: docker.io/soldevelo/postgresql-repmgr:17.6.0-debian-12-r2

Affected files:

• charts/gitea/charts/postgresql-ha/Chart.yaml
• charts/gitea/charts/postgresql-ha/README.md
• charts/gitea/README.md

I can submit a Pull Request to update the image references across the repository to ensure App Platform setups remain reliable and accessible for all users. Would you be open to that?

Hi @igor-soldev in the charts/ directory there are upstream Helm charts. Your observation that gitea Helm chart uses bitnami dependencies is valid. However App Platform does not use that dependency while deploying Gitea.

App Platform relies of databases that are manage by CNPG operator, which are deployed here: https://github.com/linode/apl-core/blob/apl-4.15.1/helmfile.d/helmfile-03.databases.yaml.gotmpl#L24

In values/gitea/gitea.gotmpl file you can find Gitea DB configuration. https://github.com/linode/apl-core/blob/apl-4.15.1/values/gitea/gitea.gotmpl#L52

I hope that clarifies the Gitea setup.

Thank you for your comment. I wanted to clarify the Gitea setup on App Platform in response to your observation regarding the Helm chart dependencies.
