Abstract

The embodiment of the invention provides a method for expanding the capacity of a PVC module in Kubernetes and a related device, and relates to the field of Kubernetes expansion. The method comprisesthe following steps: acquiring the utilization rate and the hyper-division factor of a storage space divided to a PVC module; wherein the hyper-division factor is the utilization rate of the total storage space; when the usage rate is greater than a preset threshold, determining an expansion space corresponding to the PVC module according to the hyper-division factor; wherein the size of the expansion space is inversely proportional to the size of the hyper-division factor; and expanding the capacity of the PVC module according to the capacity expansion space and the undivided storage space inthe total storage space. The embodiment of the invention has the beneficial effect of being capable of actively and efficiently expanding the capacity of the PVC module.

Description

technical field [0001] The present application relates to the field of Kubernetes expansion, and in particular, relates to a method for expanding the capacity of a PVC module in Kubernetes and a related device. Background technique [0002] With the increasing popularity of cloud computing, the container orchestration system Kubernetes (k8s for short) is used more and more frequently. However, when the business department uses k8s, when the required capacity of the PVC (Persistent Volume Claim, persistent volume claim) module exceeds the used capacity, the problem of business service unavailability may occur. [0003] At present, when the required capacity of the PVC module exceeds the used capacity, the operator needs to manually expand the capacity of the PVC module. This kind of operation is very cumbersome and inefficient. At the same time, when the operator is not familiar with the system, if there is an operation error, it is likely to cause the loss of stored data an...
