Embodiment 1

[0044] as attached figure 2 As shown, under the OpenStack environment of the present invention, the method for quickly importing the virtual machine image is to use the rbd client of the ceph cluster to import the virtual machine image into the ceph image pool, and then use the glance client to supplement the metadata of the virtual machine image to the Database, and then check whether the mirroring status is normal. If it is normal, the mirroring service can be provided externally; the specific steps are as follows:

[0045]S1. Select the upload node, label the upload node with the glance-image-upload label (label), and upload the image file to be uploaded to the upload node; the upload node accesses the storage node through the storage network. In the production environment, the storage Select a 10Gbps network port.

[0046] S2. Write a chart file on the kubernetes master node; the content of the written chart file includes the uploaded image file, the image name of the gl...

Embodiment 2

[0053] Under the OpenStack environment of the present invention, the virtual machine mirror image is quickly imported into the system, and the system includes,

[0054] The upload node unit is used to select an upload node, to label the upload node with a glance-image-upl oad label (label), and to upload the image file to be uploaded to the upload node;

[0055] The storage node unit is used to complete the data transmission between the upload node and the storage node through the storage network. In the production environment, the network port of 10Gbps is selected for storage;

[0056] The kubernetes master node unit is used to write a chart file. The contents of the chart file include the uploaded image file, the image name of glance, and the storage class (storageClass) of the uploaded ceph cluster; and use helm to install, that is, helm install–tls glance -image-upload; during the installation process, find the configuration file of the corresponding ceph cluster accordin...

Abstract

The invention discloses a method and a system for quickly importing a mirror image of a virtual machine in an OpenStack environment. The invention belongs to the technical field of cloud computing, the technical problem to be solved by the invention is how to reduce mirror image content transmission links, reduce upload time, improve success rate of mirror image import at the same time without occupying the management network flow.. According to the technical scheme, the method comprises the steps that an rbd client side of a ceph cluster is used for importing a virtual machine mirror image into a ceph mirror image pool; a grance client side is used for supplementing metadata of the virtual machine mirror image to a database; whether the mirror image state is normal or not is checked, andmirror image service can be provided for the outside normally. The system comprises an uploading node unit, a storage node unit, a kubernetes main node unit and a control node unit.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and system for quickly importing a virtual machine image in an OpenStack environment. Background technique [0002] In the field of cloud computing, OpenStack has become the standard for private cloud construction. Its core components, such as glance, have a relatively high degree of acceptance. According to OpenStack's 2019 user survey, the adoption rate of glance in the production environment is 89%. In the field of distributed storage, Ceph has become the benchmark in the industry, supported by many cloud computing and storage vendors, and has become the most widely used open source distributed storage platform. Ceph is used as the storage backend of OpenStack in 75% of production environments, and components including nova, cinder, manila, and glance can use Ceph, and glance uses Ceph's block storage as the storage backend of the image. [0003] OpenStack us...
