Datab
The OS layer beneath the datab-app snap

Ubuntu Core Images

Ubuntu Core is the target appliance distribution path for Datab Node, but the current Node image is Ubuntu 24.04 with systemd-supervised services. This page tracks the Core/snap architecture as it matures into a signed distribution image.

Why Ubuntu Core remains the target

  • Atomic updates. snapd installs new revisions side-by-side; failure to start rolls back automatically.
  • Read-only root. The OS partition isn't modified at runtime; only $SNAP_COMMON is writable.
  • Long-term security updates. Ten-year support window matches the appliance lifecycle.
  • Confinement. Every snap runs under AppArmor profiles by default.

Architectures

  • amd64 — Intel / AMD nodes. The most common configuration.
  • arm64 — Raspberry Pi 5, generic ARM appliances, NXP boards.

Image artifacts

Image artifacts are published on the Datab Node Imagespage. Current RC artifacts are Ubuntu 24.04/systemd-based; UC24 + datab-app artifacts appear here only after they are signed.

Status

Preview

Image artifacts for RC1 are TBD until the first signed publish. The image layout is finalized; the binaries are not yet uploaded.
