    For a NAS with robust container support, TrueNAS SCALE is the top recommendation, offering native Docker and Kubernetes integration on a Debian base with enterprise-grade ZFS file system support.

    OpenMediaVault (OMV) is the best lightweight, open-source alternative for lower-resource hardware, built on Debian and allowing Docker and ZFS via plugins. For users prioritizing flexible drive expansion and a user-friendly app store, Unraid (commercial) provides a unique parity-based system with extensive Docker and VM support.

    TrueNAS SCALE is ideal for those needing strict data integrity with ZFS and direct Kubernetes orchestration. OpenMediaVault suits users who want a modular, low-footprint system that can be customized with standard Linux tools. Unraid is preferred for mixed-drive arrays and users who want a simple GUI for managing thousands of applications. CasaOS acts as a lightweight interface layer that can be installed on top of Ubuntu or Debian for an immediate, user-friendly dashboard. Rockstor is a strong choice for users specifically requiring BTRFS features like snapshots and compression alongside Docker.
