- 4. 4 Under the hood: MicroOS
- 5. 5 In a Nutshell • OS focused only on containers • Minimal images • Transactional Updates • Designed for Cloud, Kubernetes, PaaS • Focused on large deployments • Reduced end-user interactions • Ready to run SUSE OpenStack Cloud Micro OS
- 6. 6 Technical Highlights ● Ready to run out of the box ● No simple bash login prompt where admin has to configure everything! ● Btrfs with snapshots and rollback for transactional updates ● Read-only filesystem with overlayfs for /etc ● Cloud-init for configuration ● Kubernetes master with dashboard to manage cluster ● Etcd ● Saltstack ● Installer or ready to use images (Cloud / Virtualization)
- 8. 8 Definition A “transactional update” is a kind of update that: ● Is atomic ● The update does not influence your running system ● Can be rolled back ● If the upgrade fails or if the update is not compatible, you can quickly restore the situation as it was before the upgrade
- 9. 9 Update ● Transactional Updates ● Automatic updates ● Can be disabled ● Maintenance Window ● Policy defined updates ● Standard RPM with zypper, snapper and btrfs progs ● SMT as local proxy
