Session
Modern edge environments demand OS images that are small, secure, and reliable—even when deployed across thousands of geographically distributed devices. Traditional approaches that rely on manual configuration or mutable operating systems break quickly at scale. RHEL for Edge solves this by using Image Builder, Blueprinting, and OSTree to create immutable, version-controlled, and reproducible edge images.
This session provides a hands-on walkthrough of designing and building production-grade edge images. We will cover how to create minimal and secure blueprints, embed system configurations, and use OSTree for atomic updates and safe rollbacks. The talk also explains best practices for image signing, validating supply-chain integrity, and keeping fleets consistent even over weak or intermittent networks.
By the end of this session, attendees will understand the full workflow—from blueprint design to deployment—and walk away with patterns they can immediately apply in manufacturing, telco, retail, and remote-site infrastructures.
