CONFIGURATION OF DECOUPLED UPGRADES FOR CONTAINER-ORCHESTRATION SYSTEM-BASED SERVICES

Abstract:

Some embodiments provide a system and method associated with a determination of an upgrade path for an application service associated with a container-orchestration system (e.g., a KUBERNETES.RTM. container-orchestration system). A container-orchestration system server may trigger, by an operator object deployed as a controller for the application service, an upgrade process. In response to the trigger, the container-orchestration system server may access a dictionary type data structure containing a plurality of tuples associated with the application service (and the dictionary type data structure may be uncoupled from the application service). The container-orchestration system server may then automatically execute a search algorithm on the plurality of tuples to determine the upgrade path from a source version to a target version for the application service. According to some embodiments, the application service may then be automatically upgraded in accordance with the determined upgrade path.
