Description

Technical Field

[0001] The present invention relates to the field of microservice access technology, and in particular to a Kubernetes-based multi-cluster microservice access method and system. Background Art

[0002] Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications. It allows users to deploy applications across multiple hosts and automatically manages their state. In a microservices architecture, an application is split into many independent services, each deployed independently, typically using container technology. Kubernetes helps manage these containerized services, including deployment, scaling, monitoring, and maintenance.

[0003] In a multi-cluster environment, users can run microservices on multiple independent Kubernetes clusters. This helps users better isolate services and manage resources, and makes it easier to scale to new environments. However, in a multi-cluster environment, users also need to consider how to enable services to communicate across multiple clusters. In practice, there are many ways to access individual microservices. For example, a central load balancer can be used to route requests to the microservices in the appropriate subcluster, but this method requires reliance on an external load balancer and increases costs. Alternatively, each microservice can be exposed externally in each cluster, but this approach results in fragmented and inconsistent traffic entry points.

[0004] Therefore, how to provide an economical and more versatile microservice access method has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] In view of this, in order to overcome the shortcomings of the existing technology, the present invention aims to provide a multi-cluster microservice access method based on Kubernetes.

[0006] In one aspect, the present invention provides a multi-cluster microservice access method based on Kubernetes, comprising:

[0007] Step S1: Initialize the correspondence between the microservice forwarding module and each sub-cluster microservice;

[0008] Step S2: The microservice forwarding module identifies the corresponding microservice based on the microservice access request sent by the user;

[0009] Step S3: The microservice forwarding module encapsulates the user's microservice access request into a standard microservice request that meets the access entry standard of the identified microservice;

[0010] Step S4: After receiving the standard microservice request, the microservice in the subcluster returns response data corresponding to the standard microservice request to the user.

[0011] Furthermore, step S1 of the multi-cluster microservice access method based on Kubernetes of the present invention includes:

[0012] Load the Kubeconfig configuration files of each subcluster through the microservice forwarding module;

[0013] Expose the IP and port of the microservice forwarding module to the outside world, and configure the mapping rules between the microservice forwarding module and the microservices of each sub-cluster;

[0014] The microservice access portal of each sub-cluster is exposed through the microservice forwarding module.

[0015] Furthermore, step S2 of the multi-cluster microservice access method based on Kubernetes of the present invention includes:

[0016] Step S21: The user sends a microservice access request to the microservice forwarding module according to the IP and port exposed by the microservice forwarding module, where the microservice access request includes a recognizable request header;

[0017] Step S22: The microservice forwarding module receives the microservice access request and finds the corresponding subcluster according to the identifiable request header in the microservice access request;

[0018] Step S23: The microservice forwarding module reads the corresponding Kubeconfig configuration file from the loaded Kubeconfig configuration files of each sub-cluster;

[0019] Step S24: The microservice forwarding module reads the request path in the microservice access request sent by the user, and identifies the corresponding microservice according to the read request path and mapping rules.

[0020] On the other hand, the present invention provides a multi-cluster microservice access system based on Kubernetes, comprising:

[0021] The control cluster is used to deploy the microservice forwarding module, which forwards the user's microservice access request to the microservice of the corresponding subcluster;

[0022] The subcluster is used to deploy microservices and return response data corresponding to the standard microservice request to the user after receiving the standard microservice request.

[0023] Furthermore, the microservice forwarding module in the multi-cluster microservice access system based on Kubernetes of the present invention is used to load the Kubeconfig configuration file of each sub-cluster and expose the microservice access entrance of each sub-cluster.

[0024] Furthermore, the microservice forwarding module in the multi-cluster microservice access system based on Kubernetes of the present invention is used to expose the IP and port to the user, receive the microservice access request sent by the user, find the corresponding subcluster according to the identifiable request header in the microservice access request; read the corresponding Kubeconfig configuration file from the loaded Kubeconfig configuration file of each subcluster; read the request path in the microservice access request sent by the user, and identify the corresponding microservice according to the read request path and mapping rules.

[0025] Furthermore, the microservice forwarding module in the Kubernetes-based multi-cluster microservice access system of the present invention is used to encapsulate the user's microservice access request into a standard microservice request that meets the access entry standard of the identified microservice.

[0026] Secondly, the present invention provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed, the steps of the Kubernetes-based multi-cluster microservice access method of the present invention are performed.

[0027] Finally, the present invention also provides a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, the steps of the Kubernetes-based multi-cluster microservice access method of the present invention are performed.

[0028] The present invention provides a multi-cluster microservice access method and system based on Kubernetes, which has the following beneficial effects:

[0029] 1. Make microservice access more lightweight and implement traffic management for sub-cluster microservices without the need for additional traffic management components.

[0030] 2. The differences between each sub-cluster are shielded, and the microservices of all sub-clusters are accessed through the management and control cluster, making the access entrance unified and easy to manage and use. BRIEF DESCRIPTION OF THE DRAWINGS
