Atomic Workstation Kalev Lember, Red Hat desktop team DevConf.cz 2018 What is Fedora Atomic Workstation? Regular Fedora, based on RPMs Shipped in a different way Atomic Workstation: changing the way we ship Fedora Workstation Base

  1. Atomic Workstation Kalev Lember, Red Hat desktop team DevConf.cz 2018

  2. What is Fedora Atomic Workstation? ● Regular Fedora, based on RPMs ● Shipped in a different way

  4. Atomic Workstation: changing the way we ship Fedora Workstation ● Base image updatable as a single unit ● Applications separate

  5. Base image: rpm-ostree ● Composed from rpms ● ostree - “git for binaries” ● Atomic updates and rollbacks

  6. Finally an easy way to test rawhide! ● rpm-ostree makes it easy to switch between trees ● It doesn’t work: just boot back to stable F27 ● Shared home directory

  7. Updating Atomic Workstation ● Base image: prepare update online, reboot into new system ● No downtime for updates; easy rollback ● Flatpaks: update online

  8. Hacking Atomic Workstation ● rpm-ostree admin unlock ● Layered rpms

  9. Applications ● Flatpaks (currently only available from 3rd party sources) ● Layered rpms

  10. Flatpaks in Fedora ● Plan is to take Fedora srpms and rebuild them as Flatpaks ● Base runtime doable without rebuilding rpms, just repacking

  11. QA-ing Atomic Workstation ● No more combinatorial explosion with rpms ● Base image testable as a single unit

  12. Thanks for attention! https://fedoraproject.org/wiki/Workst ation/AtomicWorkstation kalev in #fedora-workstation, #atomic on freenode IRC
