Abstract

The invention discloses a stateful application storage management method based on KubernetesKubernetes-based stateful application storage management method, which relates to the technical field of cloud computing, and comprises the following steps of: creating a container cluster, and configuring whether a global switch of a corresponding data volume is reserved after a stateful application of thecontainer cluster is deleted or shrunk; creating a stateful application, and selecting whether an attribute is set or not, wherein the attribute determines whether a corresponding data volume is reserved or not after the stateful application is deleted or shrunk; creating a data volume corresponding to the stateful application; Judging whether a corresponding data volume is reserved or not afterthe stateful application is deleted or shrunk according to the set attribute; and when the attribute is not set, whether the corresponding data volume is reserved is judged according to the global switch. According to the method provided by the invention, a user can select whether the related volume resources are still reserved after the stateful application is deleted or shrunk according to the actual needs of the user. W; when the volume resources are not reserved, the related volume resources can be released in time; W; when the reserved volume resource is set, the related volume resource can be reserved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a Kubernetes-based stateful application storage management method. Background technique [0002] The container cluster management system Kubernetes is an open source platform that can realize automatic deployment, automatic expansion and contraction, maintenance and other functions of container clusters. StatefulSet is a load management controller provided by Kubernetes to manage stateful applications. It is used to solve the independent life cycle management of each pod instance and provide the startup sequence and uniqueness of each instance. Kubernetes uses technologies such as StatefulSet to create stateful applications. In a converged cloud platform environment based on container and cloud platform technologies, the following problems will arise: [0003] (1) After the stateful application created after the container cluster is used for a long time is deleted or sca...

AI Technical Summary

Problems solved by technology

[0003] (1) The stateful applications created after the container cluster has been used for a long time will generate a large number of leftover data volumes after being deleted or scaled down;

[0004] (2) Relevant legacy data volumes occupy a large amount of storage space, which adversely affects the normal application volume resources of the container cluster, and may even lead to application failure due to insufficient storage resources;

[0005] (3) In some scenarios, the relevant data of the leftover data volume after the stateful application of the container cluster is deleted or shrunk is still useful to the customer, and may be mounted and used again later. In order to ensure the security of the data, it cannot Direct deletion processing;
