Gray release arrangement method based on Kubernetes platform and Istio grid technology

Abstract

The invention discloses a gray release arrangement method based on a Kubernetes platform and an Istio grid technology. According to the method, the characteristics of a virtual Service of Istio, the characteristics of a destination Rule module and the label characteristics of kubernetes are utilized, a helm publishing tool is adopted, a deployment template of the service kubernetes and related attribute values of values of the dynamic control template are flexibly generated, the flow of the micro-service AB version in the kubernetes cluster is dynamically and smoothly scheduled, and smooth gray release is quickly and stably realized, so that the test cost of test personnel is reduced, and the range of influence on services is reduced.

Description

technical field [0001] The present invention relates to the technical field of cloud computing and infrastructure, and in particular to a gray-scale release arrangement method based on Kubernetes platform and Istio grid technology. Background technique [0002] Service Mesh is used to describe the network of microservices that make up such applications and the interactions between them. As a service mesh grows in size and complexity, it becomes increasingly difficult to understand and manage. Its requirements can include discovery, load balancing, failure recovery, metrics, and monitoring. Service meshes also typically have more complex operational requirements such as A / B testing, canary rollouts, rate limiting, access control, and end-to-end authentication; Istio provides behavioral insight and operational control across the entire service mesh , thereby providing a complete solution to meet the various needs of microservice applications. [0003] Kubernetes is an open ...

Problems solved by technology

[0005] In the process of project iteration, it is inevitable that the project needs to be launched, the service changes frequently, the release cycle is short, and the speed and quality are always difficult to achieve. The test work of the project relies too much on testers, and the offline test needs to manually construct data. The structure increases the risks and impacts on releases. Nowadays, some gateway technologies like ingress-nginx and trafik are used to achieve partial grayscale releases. Some are complex, and some are not always smooth enough for business switching during the release process. It has a great impact on the business, some functions will also require additional development workload, lack of flexibility and enterprise data security and other defects
