Description

Technical Field

[0001] The present invention relates to the field of Kubernetes, and in particular to an application configuration management method based on Jenkins and Kubernetes. Background Art

[0002] Kubernetes containers have been widely used in microservice architecture systems. Container operation requires application configuration, which is primarily loaded into Kubernetes containers in the form of configmaps. Initially, technical personnel in this field wrote configmaps in a single YAML file. However, because each microservice requires different application configurations, technical personnel in this field had to maintain multiple configmap YAML files based on the number of microservices. As the number of microservices in a company increases, maintaining so many YAML files becomes increasingly difficult and error-prone, resulting in high labor costs and low efficiency. Summary of the Invention

[0003] In order to overcome the above technical deficiencies, the present invention aims to provide an application configuration management method, comprising: Step S1: deploying an application configuration management platform, including steps S1.1 to S1.4:

[0004] Step S1.1: Deploy a Kubernetes cluster and provide a database;

[0005] Step S1.2: Download the customized Jenkins image and start Jenkins using a device capable of executing kubectl commands.

[0006] Step S1.3: Create a job in Jenkins and write the pipeline script;

[0007] Step S1.4: Start the application configuration management platform in the form of a Kubernetes pod. Once the pod runs successfully, the deployment of the application configuration management platform is complete.

[0008] Step S2: using the application configuration management platform to modify an application configuration in yaml format;

[0009] Step S3: The application configuration management platform detects and determines in real time that the application configuration has been modified, automatically converts the modified application configuration in YAML format into an updated application configuration in JSON format, and transmits the updated application configuration in JSON format to Jenkins;

[0010] Step S4: After Jenkins receives the updated application configuration in json format, the script configured by the pipeline parses the updated application configuration in json format into a yaml file of configmap, and saves the yaml file to the server;

[0011] Step S5: Jenkinsjob executes the kubectl command to point to the yaml file saved in the server to update the configmap in the Kubernetes container;

[0012] Step S6: Restart the Kubernetes container to take effect of the updated application configuration.

[0013] Further, in step S1.1, the database is a MySQL database.

[0014] Further, in step S5, Jenkinsjob directly executes the kubectl command to point to the yaml file to update the configmap.

[0015] After adopting the above technical solution, compared with the prior art, the following beneficial effects are obtained:

[0016] 1. No need to manage numerous yaml files of configmap, automatically update the configmap of kubernetes after modification in the configuration management platform;

[0017] 2. Configuration management is centralized, all configuration items are in one place, and the configuration needed to be modified can be located directly by searching in the browser;

[0018] The technical solution of the present application develops an operation and maintenance platform based on Jenkins and Kubernetes, and the application configuration management method of the present application can automatically, efficiently and in real time centrally modify the application configuration and automatically update the configmap, thereby efficiently managing the numerous application configurations required for the running of the Kubernetes container, having high accuracy, and being able to record the history of the modification of the application configuration so that the process of the configuration modification can be traced back, and the labor cost is reduced.
