Description

Technical Field

[0001] The present invention relates to the technical field of microservices, and in particular, to a method and system for deploying microservices without interruption. Background Art

[0002] In traditional microservice deployment, generally, the service needs to be shut down first and then updated and deployed. At this time, the business being processed by the service may fail due to forced interruption; in addition, due to a certain time interval in the health detection of the upstream service caller, it is impossible to immediately detect that the service has been shut down, and new business requests will still be sent, resulting in exceptions such as business rejection or timeout.

[0003] Patent document CN111176873A discloses a method, device, computer device and storage medium for automatically taking a microservice offline, which relates to the technical field of microservice architecture. The method includes: confirming a microservice in an abnormal state based on heartbeat detection and / or business detection of the microservice; updating information of the microservice in the abnormal state, and pushing the information of the microservice in the abnormal state to the upstream service; the upstream service is used to take the microservice in the abnormal state offline; and pushing the information of the backup microservice to the upstream service, and the upstream service adds the backup microservice to the load to replace the offline microservice. This method uses the backup microservice to replace the offline microservice, thereby providing a timely disaster recovery function.

[0004] Patent document CN111176873A focuses on how to solve the problem after a microservice appears abnormal, but does not solve how to prevent exceptions caused by service updates. Summary of the Invention

[0040] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all fall within the protection scope of the present invention.

[0041] In order to perform microservice application updates seamlessly and smoothly and prevent business exceptions caused by microservice interruptions during deployment, the present invention realizes: 1) Without affecting microservice processing, change the status of the microservice to be updated to the offline state and ensure that the caller can detect this offline state, so that new business requests will no longer be transferred to this service; 2) After the business being processed by this microservice is completed, then close the service for update and startup; 3) Restore the microservice to the online state to provide services externally. Among them, for the offline state of the microservice, different methods are adopted for different microservice call relationships: A. For microservices only called by other microservices in the service registry. Utilize the service status detection and service forwarding mechanisms of the microservice registry to take the microservice offline in the registry before update. At this time, the ongoing business processing will not be affected, but business requests from other microservices will no longer be transferred to this service; B. For microservices called by external load devices (such as F5, LVS, etc.). Since external load devices cannot obtain the microservice status in the registry, special processing is required for these microservices. Configure the health detection method of the load device as: detect through the health detection page, remove the health detection page before update, and restore the health detection page after update.

[0042] The following specifically describes the method flow steps of the present invention.

[0043] According to a method for uninterrupted microservice deployment provided by the present invention, it includes:

[0044] Step S1: Determine the type of the microservice to be updated and perform corresponding processing;

[0045] Step S1.1: For a microservice that is only called by other microservices in the registry, send a shutdown instruction to the registry to shut down the microservice in the registry.

[0046] Step S1.2: For microservices called by external load devices (regardless of whether the microservice is called by other microservices in the registration center), rename the health detection page file of the microservice so that it cannot be detected by the load device;

[0047] Step S2: Wait for a certain period of time, and after the business being processed by the microservice is completed, shut down the service;

[0048] Step S3: Service update and startup;

[0049] Step S4: The service is back online;

[0050] Step S4.1: For microservices that are only called by other microservices in the registry, they will be automatically online in the registry after the service is started, without any additional steps;
