摘要
Utilizing several passes of a token among the operating system level virtualization applications (OSLVAs) running on each of an ordered list of nodes selectively upgrade user applications in specific containers after determining that each OSVLA hosting a container to be upgraded is live. A failed liveness check can cause a revision to the list of nodes. Post-upgrade health checks of each application, and a list-wide notification of a completed upgrade of the application instances, can follow a successful upgrade. A roll back of the upgrade across all nodes can follow an unsuccessful upgrade.
