helm/minio becomes helm/silo: chart name silo, version 6.0.0 -> 7.0.0, the MinIO wordmark icon replaced with the project's own, image.repository and mcImage.repository pointing at pgsty/silo, and the container command changed to silo. User-visible titles, comments and documentation links are rebranded. The MINIO_* environment variables and every existing values key are kept - the first Silo chart is a rename, not a values-schema migration. The hard problem is that a chart rename normally rewrites Kubernetes resource identity, and a StatefulSet's selector and volumeClaimTemplate are immutable. An existing release upgraded carelessly would either fail or orphan its PVCs. Two things address that: - Templates no longer derive the container name from .Chart.Name. It comes from a helper, so nameOverride can pin it, which means an existing release can be upgraded with nameOverride=minio, fullnameOverride=<existing-fullname> and serviceAccount.name=minio-sa and render byte-stable identity while switching chart and image. - helm-migration-guard and verify-helm-migration.sh make that a gate rather than a documented hope. The script lints the chart, renders it in distributed and standalone modes plus the optional templates, then renders the legacy chart from a pinned commit and the new chart with those three overrides and compares resource identity. The guard additionally rejects any rendered container still pulling pgsty/minio or invoking /usr/bin/minio. It runs through a pinned alpine/helm image when helm is not installed locally, so the gate does not depend on the developer's machine. Currently green over 7 compared resources. Rollback is asymmetric and the README says so: the old chart with the new image survives via the entrypoint argv shim, but the new chart with an old MinIO image does not, because `silo server` is not a command that binary knows. Only `helm rollback` is supported, never an image-only downgrade. Not addressed here: the default image tag is pgsty/silo:RELEASE.2026-08-04T00-00-00Z, which does not exist yet. The chart must not be published until the first Silo image is pushed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
