Description

Methods and apparatus for updating container processes, storage media and electronic devices Related applications This application claims priority to Chinese patent application filed on October 29, 2024, with application number 202411525762.3, entitled "Method and apparatus for updating container processes, storage medium and electronic device", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of computers, and more specifically, to a method and apparatus for updating container processes, a storage medium, and an electronic device. Background Technology Kubernetes (K8s) is an open-source container orchestration platform that provides powerful, scalable, and flexible container orchestration capabilities. It can automate the deployment, scaling, and management of containerized applications, improve the efficiency of development and operations teams, reduce complexity, and ensure high availability and reliability of applications. To ensure the continued availability and security of applications, technicians using Kubernetes need to update applications, fix security vulnerabilities, optimize performance, or introduce new features as required, which necessitates updating the container processes within Kubernetes. Currently, the typical approach to updating container processes in Kubernetes is to first terminate the container process to be updated and clear all business resources associated with that process. Then, after acquiring the process resources of the updated container process, the updated container process is started and used to take over the business processes required by the containerized application before the update. However, during the update process using the above-mentioned container process update method, the containerized application process of the existing business will terminate. During the process termination, it will be unable to receive new business requests and process the business corresponding to the business requests, resulting in a technical problem of poor business upgrade continuity. There is currently no effective solution to the above problems. Summary of the Invention This application provides a method and apparatus for updating container processes, a storage medium, and an electronic device. On the one hand, a method for updating a container process, executed by an electronic device, includes: While the first container process is running, an update request for updating the first container process is obtained, wherein the update request carries resource acquisition data, the resource acquisition data is used to acquire resources of the first process, and the first process resources are used to update the first container process. In response to the update request, the first process resource obtained based on the resource acquisition data is associated with the process resource management directory, wherein the process resource management directory is associated with the process resources of at least one container process managed by the process management component; The process management component reads the first process resource from the process resource management directory and starts a second container process based on the first process resource, wherein the second container process is an updated container process of the first container process; and The resource access information of the business resources managed by the first container process is sent to the running second container process, so that the second container process can obtain the business resources through the resource access information. On the other hand, a container process update device is also provided, including: The acquisition unit is configured to acquire an update request for updating the first container process while the first container process is running, wherein the update request carries resource acquisition data, the resource acquisition data is used to acquire resources of the first process, and the first process resources are used to update the first container process. The association unit is configured to, in response to the update request, associate the first process resource obtained based on the resource acquisition data with the process resource management directory, wherein the process resource management directory is associated with the process resources of at least one container process managed by the process management component. A startup unit is configured to read the first process resource from the process resource management directory using the process management component, and start a second container process based on the first process resource, wherein the second container process is an updated container process of the first container process; and The sending unit is used to send the resource access information of the business resources managed by the first container process to the running second container proces
