Abstract: A computing device determines that an executing first operator process is to be upgraded to a second operator process in an upgrade process, wherein the first operator process maintains on a cluster of compute nodes a desired identified state of an application. The computing device prior to initiating the second operator process, determines that the upgrade process will cause an initiation of a new container of the application to replace an existing container of the application. The computing device determines that an upgrade mode associated with the first operator process is a rolling upgrade mode, wherein the existing container and the new container will execute concurrently for a period of time. The computing device makes a determination whether computing resources needed to execute the existing container and the new container concurrently are available. The computing device takes an upgrade request action based on the determination.
