Safe Upgrades: From Tombstones to Recommendations

Explore the evolution of OpenShift's update procedure in this 37-minute conference talk from DevConf.CZ 2023. Delve into the concept of Conditional Updates, a new approach to protecting clusters during upgrades. Learn how this system evaluates potential issues in released versions, provides warnings to administrators, and offers detailed information about exposure and risk. Discover the advantages of this method over previous blocking mechanisms, allowing for more flexible decision-making based on individual cluster needs. Gain insights into the inner workings of OpenShift updates, including how update recommendation data is curated, delivered, and evaluated. Speaker Petr Muller guides you through this technical exploration of safer and more efficient upgrade processes for OpenShift clusters.
