Embodiment Construction

[0052] In order to clarify the purposes of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] Based on the above object, a first aspect of the embodiments of the present invention there is provided a load balancing cluster websocket service method according to an embodiment. figure 1 It shows a schematic flow chart of the method.

[0054] like figure 1 As shown, the method may comprise the steps of:

[0055] S1 CRD create an instance of the corresponding websocket copy for each service cluster, and a copy of the recorded information for each service websocket and rebalance flag corresponding to the CRD.

[0056] You can customize the CRD resources in the cluster, one corresponding to each create their own copy of the CRD instance when you start websocket copy of the service, for the record within the service websocket copy number of messages in the last minute and the need ...

Abstract

The invention provides a cluster websocket service load balancing method and device, equipment, and a readable medium. The method comprises the following steps: creating a corresponding CRD instance for each websocket service copy in a cluster, and recording the information of each websocket service copy and a rebalance flag bit into the corresponding CRD; in response to information update in the CRD of the websocket service copy, judging whether a rebalance action of the websocket service copy needs to be triggered or not based on a rebalance algorithm; in response to a rebalance action needing to trigger the websocket service copy, modifying the rebalance flag bit, recorded in the CRD corresponding to the websocket service copy, into a rebalance proportion value; in response to re-updating of information in the CRD of the websocket service copy, performing rebalancing of the websocket service copy according to the rebalancing proportion value recorded in the CRD. By using the scheme provided by the invention, the problem of dynamic balance of the workload between the multi-copy websocket servers in the k8s cluster can be solved, and the coping capability of the websocket servers in a traffic emergency scene is improved, so that the practical value is very high.

Description

Technical field [0001] The present invention relates to the field of computer, and more particularly to a method, apparatus, apparatus, and readable medium of a cluster WebSocket service load balancing. Background technique [0002] Kubernetes (K8S) is a Google Open Source Container Cluster Management System. On the basis of Docker technology, a series of complete functions such as deployment operation, resource scheduling, service discovery, and dynamic telescopic, improved the convenience of large-scale container cluster management. [0003] In a K8S cluster, a means of increasing the cluster load capacity is to increase the number of nodes in the cluster, but as the number of nodes is increasing, the operation and maintenance cost is constantly increasing, and most of the time load is very low, it is very low. The overall usage rate of the node is very low, one side of the business in order to cope with the daily random traffic summation, the number of copies is as high as pos...
