Abstract

The invention discloses a method and a system for realizing isolation distribution of a storage volume of a stateful application. The method comprises the following steps of: receiving an application demand of the stateful application on the storage volume; screening out a storage node list meeting storage volume requirements; filtering the storage node list again; scoring the storage node list filtered and screened again according to a storage selection strategy specified in the demand; creating a storage volume meeting the requirement on the selected node; and providing the storage volume for the stateful application in a storage service mode for mounting and using. The storage resource screening method has the beneficial effects that the storage layer resources can be effectively filtered, the storage node resources which cannot meet the storage requirements of isolation and stateful applications are screened out, the storage resource creation failure caused by insufficient resources in the storage resource creation stage is avoided, and it is ensured that the storage resources with isolation can be successfully and automatically allocated.

Description

technical field [0001] The present invention relates to the field of Kubernetes storage, in particular, to a method and system for realizing isolated allocation of storage volumes for stateful applications. Background technique [0002] Kubernetes is a container-based cluster management system. It is built on container operating environments such as docker and container. It is used to manage containerized workloads and services. It is a portable and scalable open source platform with a large and fast A growing ecosystem with widely available services, support and tools. [0003] A Pod is the smallest deployable computing unit created and managed in Kubernetes, containing one or more containers that share storage, networking, and a declaration of how to run these containers. A Pod models an application-specific "logical host" that contains one or more application containers that are relatively tightly coupled together. [0004] A PV (PersistentVolume) is a piece of storage ...
