Embodiment Construction

[0073] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood, and the scope of the present application can be fully conveyed to those skilled in the art.

[0074] Such as figure 1 As shown, an existing Kubernetes overall architecture is provided. The existing Kubernetes architecture mainly includes control plane components and workload plane components. The corresponding upgrade solution is also divided into two parts: control plane upgrade and workload plane upgrade. Plane upgrade mainly refers to the rolling upgrade of control plane components, including the upgra...

Abstract

The invention discloses a Kubernetes upgrading method and device for a container cluster management system. The method comprises the steps of obtaining an upgrading request; according to the upgradingrequest, migrating the Kubernetes resources in the low-version cluster to the high-version cluster; updating the container in the high-version cluster according to the resources in the high-version cluster; and upgrading the low-version Kubelet on the host machine to the high-version Kubelet, and taking over the updated container in the high-version cluster from the high-version Kubelet so as tocomplete the upgrading process. The upgrading method can be used for upgrading the cluster of any version, the universality is higher, the risk of overall upgrading of the cluster is reduced, the riskis reduced to the host machine dimension, and other containers and host machines in the cluster cannot be influenced by upgrading failure of one host machine. Besides, the problem of container restarting in the upgrading process is solved, container restarting cannot be caused by upgrading, a user does not have perception, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a container cluster management system Kubernetes upgrade method and device. Background technique [0002] Kubernetes is a container cluster management system open sourced by Google, which supports automatic deployment, large-scale scalability, and application container management. When an application is deployed in a production environment, multiple instances of the application are usually deployed to load balance application requests. Multiple containers can be created in Kubernetes, each container runs an application instance, and then through the built-in load balancing strategy, the management, discovery, and access of this group of application instances are realized, and these details do not require operation and maintenance personnel to go to Complex manual configuration and processing. [0003] The existing Kubernetes cluster upgrade solution is officially re...
