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).

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.
