Nextcloud, the self-hosted file-sync and content-collaboration platform. Reconstructed clean-room on a hardened Wolfi php-8.4-fpm + nginx runtime (nonroot, read-only rootfs); the chart installs via occ and provides a MariaDB backend. Nextcloud is AGPL-3.0-only (strong copyleft).

Version

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.

The chart pins its image by this signed digest, so you never track it yourself. Signatures, SBOM, and provenance attach to the same digest.

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
