The application discloses a stateless access method and server based on a K8s cluster, and the method comprises the following steps: obtaining a service request sent by an upper application to an external service; when the service request is routed to a master POD by the external service, processing the service request by the master POD to obtain a corresponding processing result, and sending the processing result to the upper application; when the master POD generates state data, sending the state data to the internal service of a backup POD by the internal service of the master POD, so that the backup POD obtains the state data, and data synchronization between the backup POD and the master POD is realized. The method can make two stateful PODs in the K8s cluster have redundancy functions such as mutual communication, request forwarding and data synchronization, so that the two redundant stateful PODs are externally embodied as stateless.
