Method and system for automatically recycling cluster cloud hard disk, terminal and storage medium

Abstract

The invention provides a method and system for automatically recycling cluster cloud hard disks, a terminal and a storage medium. The method comprises the steps of setting a container volume information database; collecting first information and second information of the container volume in a container volume creation process, and storing the first information and the second information into the database in pairs; extracting target container volume first information from the received container volume deletion request; and searching matched second information from the database according to thefirst information of the target container volume, and deleting the container volume according to the matched second information. According to the invention, an original underlying storage resource cleaning mode is optimized, a user can select whether to delete the cloud hard disk or not according to actual production requirements, higher flexibility is provided, and when the user selects to deletethe cloud hard disk, two deletion mechanisms are adopted to ensure that the cloud hard disk needing to be deleted is correctly deleted, so that the waste of cloud hard disk resources is avoided.

Description

technical field [0001] The present invention relates to the technical field of cloud platforms, in particular to a method, system, terminal and storage medium for automatically recovering clustered cloud hard disks. Background technique [0002] OpenStack is a platform for building and managing private and public clouds using virtual resource pools. Kubernetes (k8s) is an open source container cluster management system. In K8s, all containers run in Pods. k8s can be deployed in virtual machines or cloud physical machines provided by openstack. In the openstack environment, the cloud hard disk service provided by cinder is generally connected to achieve persistent remote storage of data. The cinder-csi plug-in of k8s can create a cinder cloud hard disk by calling the openstack interface, and then mount the cinder cloud hard disk to a specific directory of the virtual machine where k8s is located and map it to the container process of the pod to realize the k8s pod in the op...

Problems solved by technology

[0004] There is a problem with this method: obtaining the pv list through the k8s interface requires the cluster to be in a normal state. If the cluster state is abnormal, the pv list cannot be obtained through the k8s interface, and the cinder volume cannot be deleted.

When deleting a cluster, when the cluster is deleted but the volume cinder volume mounted on the cluster fails to be deleted, because the cluster has been deleted, it is difficult to see which cluster the cinder volume belongs to from the name of the cinder volume. It is also difficult for users to manually delete the cinder volume, which causes unreasonable occupation and waste of cloud hard disk resources
