SCOMB Update: Internal Image Registry Completed + sonic-cli Revival
by Rankan Sen May 18, 2026

May 18, 2026

Hi everyone, I’m happy to share a key milestone for SCOMB: we have successfully completed the migration to an internal image registry pipeline for SONiC builds. *What we’ve built:* SONiC image builds has been moved to internal repositories and a local registry. This change provides: * Reduced dependency on external Microsoft repositories * Elimination of redundant base image rebuilds across pipelines * Lower load and fewer duplicate requests to upstream services during parallel builds * Faster and more predictable build and retrieval times through local infrastructure All image artifacts are now served through our internal registry pipeline. *Performance improvements:* A significant reduction in build time was observed after adding prefetching of slave images. * Previous build time: ~5 hours * Current build time: ~2.5–3 hours This improvement comes primarily from eliminating redundant slave image builds. However, additional gains are possible by enabling and tuning caching layers (e.g., build cache, registry cache, and layer reuse), which are not fully optimized yet. *Test access:* You can access and test the latest built images here: https://scomb.demo.alasca.cloud/local-build/ <https://scomb.demo.alasca.cloud/local-build/> Please verify: * Compatibility with your current workflows * Image stability * Any issues during boot, or deployment *What’s next? sonic-cli revival:* We are restarting development on the |sonic-cli| project and looking for contributors. Initial analysis shows that the current SONiC management framework provides only a minimal baseline implementation. The majority of the existing codebase is in Go and Python. *Roadmap focus* We will focus on: * Fixing existing bugs and stability issues * Adding missing management features * Expanding coverage across SONiC system components * Improving usability and consistency of CLI workflows *How you can help* We need community input to guide development. If you have identified: * Missing CLI features * UX gaps or workflow issues * Bugs or inconsistencies in current behavior please create work items in SCOMB. All feedback, including code contributions, feature requests, and bug reports, will directly help shape the roadmap and accelerate development. We will progressively define and publish detailed work items as we finalize the feature set. Looking forward to your feedback and contributions.

CI Update – Automated PR Merging in SONiC Images
by Rankan Sen April 21, 2026

April 21, 2026

Dear community, Following the discussion in the last SCOMB meeting, the CI pipeline has been updated to support automatic merging of PRs from the upstream into the build. To use this, add the required PR IDs to the |PR_LIST| variable in the GitLab CI YAML: PR_LIST: "10809 11802 12429 22641 25325 7615 7757 9491" Leave this empty if there is nothing to be merged. These PRs will be merged automatically along with the changes from the current branch during the build process. Please review the implementation and share any feedback or alternative approaches if applicable. The latest image for Edgecore DCS203 is available here: https://scomb.demo.alasca.cloud/sonic-images/master-ci-pipeline/2026-04-21_…<https://scomb.demo.alasca.cloud/sonic-images/master-ci-pipeline/2026-04-21_…> Best regards, Rankan ** Cloud&Heat Cloud&Heat Technologies GmbH Königsbrücker Straße 96 (Halle 15) | 01099 Dresden *+49 351 479 367 00* *rankan.sen(a)cloudandheat.com | **www.cloudandheat.com* <https://www.cloudandheat.com> *Green, Open, Efficient.* Ihr Cloud-Service- und Cloud-Technologie-Provider aus Dresden. <https://www.cloudandheat.com/> Commercial Register: District Court Dresden Register Number: HRB 30549 VAT ID No.: DE281093504 Managing Director: Nicolas Röhrs Authorized signatory: Dr. Marius Feldmann

SONiC build performance – thoughts and next steps
by Rankan Sen March 30, 2026

March 30, 2026

Dear all, Over the past few days, we’ve been running multiple SONiC builds as part of the SCOMB effort, and I spent some time stress testing the build process. A few quick observations: * The best speedup so far was with *16 parallel jobs* * Build time was approximately *3 hours* * A completely fresh build (no cached/pre-sourced images) takes around *~5 hours* Even with these optimizations, a build time of ~3 hours is not practical for day-to-day development, particularly when multiple users are iterating on builds. To support a more collaborative and efficient workflow, this needs to be reduced further. From what I’ve seen so far: * There are likely *redundant packages and images* in the build * Not everything included seems necessary for a *basic or iterative build* So a first step could be: * Reviewing dependencies more critically * Stripping down the build to only what’s actually required That said, this is just an initial direction. There are likely better approaches (e.g., caching strategies, registry mirroring, incremental builds), so it would be great to get more input. If you have suggestions, please share them here: https://gitlab.com/alasca.cloud/scomb/sonic-buildimage/-/work_items/18<https://gitlab.com/alasca.cloud/scomb/sonic-buildimage/-/work_items/18> Also, feel free to pick up any open tickets if something looks interesting.
