Data storage method, device and equipment and readable storage medium

Abstract

The invention discloses a data storage method, device and equipment for a kubernetes cluster and a storage medium. According to the invention, the virtual router can realize communication between thevirtual machine of the tenant network and the control node; a csi-cinder plug-in is installed on a kubernetes cluster of a virtual machine; after the storage system is subjected to unified managementthrough the cinder service, the kubernetes cluster can directly access the cinder service of the control node through the csi-cinder plug-in by using the communication mode, so that the persistent data storage of the kubernetes cluster is realized.

Description

technical field [0001] The present invention relates to the technical field of data storage, and more specifically, relates to a data storage method, device, equipment and storage medium of a kubernetes cluster. Background technique [0002] OpenStack is an open source cloud operating system, and is currently the most popular open source IaaS (Infrastructure as a Service, Infrastructure as a Service) platform for managing virtual machine resources. With the continuous development of container technology, customers have more and more demands for some IaaS+ services in addition to the basic resource requirements of IaaS. Among them, the most demanding ones are container cluster services and container-based application deployment. Kubernetes is currently the most popular open-source container orchestration engine, and kubernetes on openstack is an effective combination solution that provides mixed resources of virtual machines and containers, that is, deploying kubernetes clust...

Problems solved by technology

In addition to providing the container service itself, the data of the application deployed on the container also needs to be persistent, so it is necessary to support the persistent storage of the container, because the container itself cannot perform persistent storage, and the storage associated with the container disappears.

The current general practice is to use local directories as persistent storage, but business migration is not possible. In addition, a storage system is deployed to provide persistent storage for containers managed by kubernetes. The disadvantage of this approach is that kubernetes and openstack each manage a set or There are multiple sets of storage systems, and the management of the storage system and the connection between the data network and the business network of the virtual machine are required to allow the virtual machine to access

In this way, two or more sets of storage system resources are needed to support the entire platform, and the requirements for the customer's network are relatively strict, and it is not friendly to use.
