Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.
First, some terms related to the embodiments of the present invention are explained to facilitate understanding by those skilled in the art.
1. ISO is one of the storage formats for compact disc images (CD mirrors) on computers, and is commonly named after ISO in computers, also known as ISO image files, because it is a file stored according to the ISO-9660 standard on CD-ROM file systems. The optical disk has only one file in form, can truly reflect the content of the optical disk, and can be created by recording software or an image file making tool.
2. The OpenStack is an open-source cloud computing management platform project, and is formed by combining several main components to complete specific work. OpenStack supports almost all types of cloud environments, and the project aims to provide a cloud computing management platform which is simple to implement, can be expanded in a large scale, is rich and has a unified standard. OpenStack provides a solution for infrastructure as a service (IaaS) 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 in the drawings described above are used for distinguishing similar objects and not necessarily for describing a particular order or sequence. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein.
Reference herein to "a plurality or a number" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In view of the above, embodiments of the present invention provide a method, an apparatus, and a storage medium for cloud platform creation, so as to solve the problem that a cloud platform cannot directly upload and use iso-format images.
