the embodiment is applied to a scenario of service call among cross clusters in a distributed service cluster system and a micro service architecture, service discovery (service discovery) is a basic stone for interconnection and interworking between the distributed system and the micro service architecture, and services in the service clusters are different from static services of a physical or virtual host computer IP, but are dynamic services of a dynamic IP which are automatically generated in a container based on dynamic deployment of a Kubernetes cluster, namely, the services are continuously changed, updated, dynamically expanded and destroyed. In order to discover and call services in different clusters, based on this, the present embodiment proposes and designs a method for calling services between service clusters, firstly, obtaining services in a first service cluster and a second service cluster, and address information of each service, where the first service cluster and the second service cluster refer to different sub-service clusters in the service clusters, and are not specific two sub-service clusters, and may be understood that the first service cluster and the second service cluster characterize all sub-service clusters in a service inlet cluster, and then, by maintaining a service discovery and registration plug-in, obtain services in the first service cluster and the second service cluster, and further, in order to implement call of services, address information corresponding to each service needs to be obtained.
It should be noted that the service discovery and registration plugin of this embodiment may be configured to be associated with each sub-service group, that is, associated with the first service cluster and the second service cluster, and then discover the registrable service from the first service cluster and the second service cluster, and obtain address information corresponding to the service from the first service cluster and the second service cluster.
It should be noted that, since the services in the service clusters are dynamic, a preset time interval may be set, and after every preset time interval, the services in the first service cluster and the second service cluster and the address information of each service are obtained; or, obtaining the change information of the service in the first service cluster and the second service cluster, so as to maintain the timeliness of the service.
It should be noted that the naming or the form of different services in different service clusters is different, and after the services in the first service cluster and the second service cluster are acquired, the services are converted into the service reading form with the specified format, so that the services are convenient to manage.
It should be noted that the naming or form of the different services can be identified by AI and then converted into a service reading form in a specified format.
