Removing legacy chart versions from the Helm index

· 2 min read

If you've been getting helm repo update warnings — or if you watch our ArtifactHub feed — you may have noticed errors about a missing Bitnami Postgres image:

error scanning image docker.io/bitnami/postgresql:14.5.0-debian-11-r35:
image not found (package platzio:0.6.2)

We've removed the entries that triggered it.

What happened​

Platz chart versions up to and including 0.6.2 declared a dependency on the Bitnami PostgreSQL subchart, which in turn pulled docker.io/bitnami/postgresql:14.5.0-debian-11-r35. In late 2025 Bitnami moved their historical image tags to a separate bitnamilegacy namespace and deleted them from docker.io/bitnami/*. The Helm chart still references the old path, so scanners (and anyone trying a fresh install of an old version) get a 404.

The dependency itself was removed in v0.6.3. The reasoning is in the v0.6.8 release notes and on the Database page: operators get full control over the database, and Platz doesn't ship with a specific database chart.

What changed​

We removed entries <= 0.6.2 from the Helm repository index. The repository now serves 0.6.3 through 0.6.8. That's enough history to roll back across the post-Bitnami removal; everything older was tied to the broken dependency anyway.

The release tarballs themselves are untouched — they still live on GitHub Releases. If you've pinned a specific older version by URL in your own automation, it will continue to resolve.

What you should do​

  • If you're on 0.6.3 or later: nothing. You won't see any change.
  • If you're still on 0.6.2 or earlier: plan an upgrade to the latest 0.6.x. Provision Postgres yourself (RDS, Cloud SQL, self-hosted — see the Database page), populate the postgres-creds secret, and bump the chart. The schema migration runs automatically on API pod startup.
  • If you depended on the bundled Bitnami subchart in production: same as above. The bundled subchart was never intended for serious production use, and it's now structurally broken; migrating off it is the path forward.
