The disclosure provides a method for upgrading components of a container-based cluster. The method generally include receiving, at the container-based cluster, an indication of one or more pods and one or more nodes in the cluster to upgrade, adding an annotation to each of the one or more nodes having at least one of the one or more pods running thereon, performing a pod upgrade, and performing a node upgrade, wherein performance of the pod upgrade and the node upgrade overlap at least partially in time, and wherein performing the node upgrade comprises: selecting a first node, determining at a first time that the first node includes an annotation, refraining from upgrading the first node at the first time, determining at a second time after the first time that the first node does not include the annotation, and upgrading the first node at the second time.
