The world’s premier FSDK server operating system.
Bluefin Server an operating system designed for modern workloads. The use case is the same as Flatcar Linux, Fedora CoreOS, and Talos.
The difference is this is DDI first and built with buildstream. API and GitOps driven.
- FSDK-first server OS work in progress
- Image-based updates and atomic rollbacks
- Fully automated GitOps-driven builds
- Pure DDI, follows modern linux patterns
Use the local just targets while iterating:
just show-me-the-futureAll versions just follow fsdk. Tags are derived from the pinned junction ref in
elements/freedesktop-sdk.bst:
:latest-- rolling:25.08-- FSDK minor line:25.08.13-- FSDK point release (treated immutable)
Every image self-declares its base via io.projectbluefin.fsdk.version and
io.projectbluefin.fsdk.ref labels.
Requires podman and just. BuildStream runs
inside the FSDK bst2 container -- nothing to install.
just validate # resolve the element graph
just build # build + load ghcr.io/projectbluefin/base:latest
just verify # assert distroless + certs + tzdata
just tags # show derived tags
GitHub Actions compiles the entire project (Standalone OS DDI and bootable installer) and handles publishing automatically. Automated Renovate manages updates to core platform dependencies.
| Trigger | Workflow / Job | What happens |
|---|---|---|
| Pull request | build.yml |
Resolves element graph (just validate) and executes raw BuildStream compilation to verify stability. Resolves/tracks Renovate refs automatically if opened by Renovate. |
Push to main, workflow_dispatch |
build.yml |
Builds stand-alone DDI OS, live installer, and target UKI using /mnt SSD storage on GHA hosted runners, then creates/updates the corresponding GitHub Release and uploads all compiled assets. |
No PATs/App tokens/repository_dispatch are used; Renovate is the control driver.
