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_COMMONis 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.
