Zusammenfassung:An update control device of a container-based cluster update system constructs a master node in a new container-based cluster and constructs a minimum number of worker nodes required to execute a migration target application. The update control device deletes a migration target application of a container-based cluster in an initial state, deletes a worker node in which no application is installed, adds the worker node to a new container-based cluster, and sequentially migrates the migration target application to perform update.
