Detailed Description
In order to further describe the technical means and effects adopted by the present invention for achieving the intended purpose, the following detailed description of the present invention is given with reference to the accompanying drawings and preferred embodiments.
First, some terms related to the embodiments of the present invention will be described so as to be easily understood by those skilled in the art.
1. ISO is one of the storage formats of compact disc mirroring (CD Mirror) on a computer, and is commonly named after the suffix in the computer because it is a file stored according to the ISO-9660 related CD-ROM file system standard. The optical disk has only one file in form, can truly reflect the content of the optical disk, and can be created by the burning software or an image file making tool.
2. OpenStack is an open-source cloud computing management platform project, and specific work is completed by combining several main components. OpenStack supports almost all types of cloud environments, and the project goal is to provide a cloud computing management platform that is simple to implement, scalable on a large scale, rich, and standard-unified. OpenStack provides an infrastructure as a service (IaaS) solution through various complementary services, each providing an API for integration.
It should be noted that the terms "first," "second," and the like in the description and the claims of the embodiments of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein.
Reference herein to "a plurality of" or "a number" means two or more than two. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
Because the requirements of certain special scenes often appear in the use process of the cloud platform, the customization requirements of the images are relatively improved, but the image format used by the OpenStack cloud platform is not the most commonly used iso format, so that the problems of image conversion and uploading are introduced.
As shown in fig. 1, a schematic implementation flow chart of a method for creating a mirror image for a cloud platform according to an embodiment of the present invention may include the following steps:
s11, receiving an ISO mirror image file installed by the operating system uploaded by the user.
In specific implementation, a user can upload an operating system installation CD/DVD ISO mirror image file to an OpenStack mirror image service through a web page of a browser.
S12, creating a virtual machine through virtualization software according to the received ISO image file.
In this step, a new instance is started by the ISO image file uploaded by the user, i.e. an instance is started from this operating system ISO image. The operating system is installed through a VNC (Virtual Networking Computing, virtual network console) or SPICE (Simple Protocol for Independent Computing Environment) console in the OpenStack dashboard (dash board).
Specifically, after the new instance is started, the installation function of the operating system may be completed according to the VNC console provided through the dashboard.
In the implementation, after the operating system is installed, the installed operating system can be configured according to the set configuration parameters. Specifically, the operating system may be configured according to the application program to be installed and according to the requirements of OpenStack, for example, to a group-init or equivalent script, launch SSHD (solid state hybrid hard disk) telnet/RDP (Remote Desktop Protocol ) service, or the like.
S13, converting the created virtual machine into a file with a preset format, and uploading the file to the cloud platform.
In the step, a preset script is called to create a snapshot of the virtual operating system; and aiming at the created snapshot, running a preset command to convert the snapshot into a file in a preset format. The preset command may be, but is not limited to, a Glance Image-Update command.
Specifically, for a newly created instance, a script is invoked to create an instance snapshot of the instance, run a Glance Image-Update command, or Update snapshot information from the dashboard if the dashboard provides the corresponding functionality, converting the Image type to the Image type. Optionally, other metadata may also be added.
In the embodiment of the invention, aiming at the user with the OpenStack, the image creation method is provided, and the image capable of meeting the requirements is created by creating the image on line. The user creates a new image on line through an OpenStack dashboard provided by the cloud service, and by means of the function, an end user does not need an additional virtual machine management program, does not need to upload the image to the OpenStack image service by itself, and only needs to install an operating system CD/DVD ISO image file.
The invention integrates the process of image creation in the form of the WEB application of the B/S architecture. And on the premise of not influencing a primary system, uploading, compressing and packing the ISO image file. And finally, generating a mirror template for the OpenStack platform. The scattered functions of a plurality of links are reassembled in the form of WEB pages in the whole process. The image uploading function of simpler test is completed, and the original function is supplemented and enhanced. According to the method provided by the embodiment of the invention, the ISO mirror image file is uploaded to the server, and the mirror image corresponding to the ISO mirror image file is created online, so that the problems of file format, uploading failure and the like introduced by uploading after the mirror image is created offline are avoided, and the success rate of creating the mirror image is improved.
Based on the same technical concept, the embodiment of the present invention further provides a device for creating a mirror image by using a cloud platform, as shown in fig. 2, which is a schematic structural diagram of the device for creating a mirror image by using a cloud platform provided by the embodiment of the present invention, including:

a creating unit 22, configured to create a virtual machine through virtualization software according to the ISO image;
and the conversion unit 23 is used for converting the created virtual machine into a file with a preset format and uploading the file to the cloud platform.
In an implementation manner, the device for creating a mirror image by using the cloud platform provided by the embodiment of the invention further includes:
the configuration unit is used for configuring the created virtual machine according to preset configuration parameters before the created virtual machine is converted into a file with a preset format by the conversion unit and then uploaded to the cloud platform.
