Resource allocation method, device, electronic equipment and storage medium

Abstract

The invention relates to a resource allocation method, a resource allocation device, electronic equipment and a storage medium. The method comprises the steps of binding a mounted persistent volume according to a received persistent volume declaration, and enabling the capacity of the mounted persistent volume to be a first capacity value; creating a disk mirror image file on the mount persistentvolume according to the first capacity value; mounting the disk mirror image file to a device; formatting the equipment; and mounting the equipment to a directory folder on a host, so that the mountedpersistent volume is associated with the directory folder. According to the technical scheme, the excessive occupation of a host disk due to increase of application log files is effectively avoided.The problem that other application programs cannot be normally started due to too large log files or output files is avoided. The physical resource isolation between different applications on the samehost is fully achieved, and normal operation of all the application programs is guaranteed.

Description

technical field [0001] The present application relates to the field of server management, and in particular to a resource allocation method, device, electronic equipment and storage medium. Background technique [0002] Kubernetes is Google's open source container cluster management system, which is used to manage containerized applications on multiple hosts in the cloud platform. Based on Docker technology, it provides containerized applications with a series of complete functions such as deployment and operation, resource scheduling, service discovery, and dynamic scaling, which improves the convenience of large-scale cluster management. [0003] A container in Kubernetes is a persistent storage volume (Persistent Volume, hereinafter referred to as a persistent volume). Persistent volumes are network storage provided to administrators and users in the form of application programming interfaces. Persistent volumes are created by administrators in the cluster.

Problems solved by technology

[0005] However, the capacity in the persistent volume declaration is only used as a binding parameter, and it does not actually limit the size of the log files in the persistent volume.

As the application runs, the generated log files will become larger and larger. Due to the directory mapping between the persistent volume and the host, the increase in log files in the persistent volume will also cause the log files in the host directory folder to become larger and larger. , there is a risk of occupying the host disk, causing other applications to fail to start normally
