Problems solved by technology

[0003] The workload of the Kubernetes cluster can use a variety of storage methods. Most disk plug-ins use remote storage. This is to make persistent data and computing nodes independent of each other. However, remote storage usually cannot provide the excellent read and write performance of local storage.

Abstract

The invention particularly relates to a method for automatically creating and mounting an LVM volume in a K8s environment. The method for automatically creating and mounting the LVM volume in the K8senvironment comprises the following steps of: based on the Kubernetes environment, firstly, making a mirror image for executing automatic creation and mounting of the LVM volume, and then, defining aConfigmap tube and a Job management single copy Pod to run the made mirror image, configuring container permission, environment variables, mount required and selecting nodes; and finally, using a Kubernetes client to operate the previously created yaml file, including Configmap and Deployment, so as to achieve automatic creation and LVM volume mounting of target node operation; repeated operationcan be realized, subsequent expansion of the LVM volume is supported, node service is provided, and local storage is used. According to the method for automatically creating and mounting the LVM volume in the K8s environment, conversion from the target disk to the LVM volume is completed by reading related configurations through Kubernetes Job, and the LVM volume is mounted on the target directoryto provide service for use, so that the usability and manageability are greatly improved compared with the process of manually completing disk initialization and mounting, and the requirement of using local storage by Kubernetes service in the production environment can be met.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for automatically creating and mounting LVM volumes in a K8s environment. Background technique [0002] Kubernetes, referred to as K8s, is an abbreviation formed by replacing the 8 characters "ubernete" with 8. As an open source, used to manage containerized applications on multiple hosts in the cloud platform, Kubernetes' goal is to make deploying containerized applications simple and efficient (powerful). Kubernetes provides a mechanism for resource application deployment, planning, updating and maintenance. [0003] Kubernetes cluster workloads can use multiple storage methods. Most disk plug-ins use remote storage to make persistent data and computing nodes independent of each other. However, remote storage usually cannot provide excellent read and write performance of local storage. LVM (Logical Volume Management) represents a local disk directly bound to ...
