Using OSTree Atomic Updates to Reduce Outage Times in StarlingX Cloud Upgrades

Learn about OSTree's implementation in StarlingX R8.0 through this 31-minute technical talk that explores how atomic updates significantly reduce downtime during edge cloud upgrades. Dive into OSTree's core functionality as a Linux-based upgrade system, including its git-like management of root filesystem versions and pre-deployment installation capabilities. Explore the technical challenges and solutions of integrating OSTree into the StarlingX cloud environment, covering build environment modifications, installer adaptations, and patching framework changes. Examine practical aspects of OSTree upgrades, including parallel patch delivery across multiple releases, and evaluate the tradeoffs between pure OSTree implementation versus hybrid approaches combining package managers with OSTree. Presented by Greg Waines, this session provides valuable insights for developers and system administrators working with edge cloud infrastructure and system upgrades.
