Method, apparatus, device and medium for performing resource schedule in cluster

Abstract

There are provided methods, apparatuses, devices, and media for performing resource schedule in a cluster. In a method, a network service instance is created for managing a network service of the resource instance. A network link is established for accessing the resource instance using a network address of the resource instance and a network port that is allocated to the resource instance. A network state in the network service instance is updated based on the network link. In response to detecting that the network state indicates that the network link has been established, the resource instance is launched to communicate with the launched resource instance via the network link. With example implementations of the present disclosure, there is provided an access manner that does not rely on dedicated capabilities with any particular cluster. In this way, resource instance access under multiple clusters is managed in a general and unified manner.
