Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of cloud computing, and particularly relate to a method and device for creating a private image in a public cloud, a computing device, and a computer readable storage medium. BACKGROUND

[0002] An image (Mirroring) is a template of a flexible cloud server, which at least contains an operating system. In actual application, the image can also contain application software (for example, database software) and private software. The image can be divided into a public image and a private image. The public image is a common standard operating system image, which is visible to all tenants and can include an operating system and pre-installed public applications. The private image is an image created by a tenant, which is only visible to the tenant and can include an operating system, pre-installed public applications, and private applications of the tenant.

[0003] At present, when creating a private image, a local existing image is usually registered as a private image through a private image import function, but a private ISO image cannot be registered, and a tenant cannot use an ISO file to create a private image on a cloud management platform. SUMMARY

[0004] Embodiments of the present application provide a method and device for creating a private image in a public cloud, a computing device, and a computer readable storage medium. By installing an operating system and related drivers included in an ISO file on a temporary cloud server, a tenant can use an ISO file to create a private image on a cloud management platform on a network side.

[0005] Firstly, this application provides a method for creating a private image in a public cloud, which is applied to a cloud management platform on the network side. During the creation of the private image, the cloud management platform can provide an ISO file upload interface, which allows tenants to easily upload ISO files. The cloud management platform can then obtain the ISO file uploaded by the tenant, which contains the operating system's installation files. Simultaneously, the cloud management platform also provides an ISO image registration interface, a cloud server installation interface, a cloud server configuration interface, and a cloud server image acquisition interface. The ISO image registration interface receives a first operation input by the tenant, and the cloud management platform can register the ISO file as an ISO image on the public cloud based on this first operation. This ISO image contains the operating system's installation files and registration... Information; The cloud server installation interface is used to receive a second operation input by the tenant, and the cloud management platform can install the operating system installation files carried by the ISO image into the temporary server according to the second operation; The cloud server setup interface is used to receive a third operation input by the tenant, and the cloud management platform can set up the running environment in the operating system of the temporary server according to the third operation; The cloud server image acquisition interface is used to receive a fourth operation input by the tenant, and obtain the image of the temporary cloud server with the running environment set up according to the fourth operation, and record the image as the tenant's system disk image on the public cloud, wherein the system disk image is used to provide the tenant with a cloud server with the operating system and running environment set up on the public cloud.

[0006] The cloud management platform can create the system disk image required by the tenant based on a series of operations input by the tenant and the ISO file uploaded by the tenant. This is the private image required by the tenant, which can improve the user experience and meet the actual application needs of the tenant.

[0007] In one possible implementation of the first aspect, the cloud management platform can also provide a cloud server deletion interface. This interface can receive a fifth operation input by the tenant, and based on this fifth operation, the cloud management platform can delete the temporary cloud server after creating the private image. This releases the resources occupied by the temporary cloud server, avoiding unnecessary resource occupation and waste.

[0008] In one possible implementation of the first aspect, the cloud server installation interface provided by the cloud management platform can also be used to receive a sixth operation input by the tenant. Furthermore, when installing the operating system, the cloud management platform can install the operating system for the temporary cloud server based on the sixth operation, thereby enabling the tenant to customize the installation of the operating system.

[0009] For example, in the process that the cloud management platform installs an operating system for the temporary cloud server, the tenant can specify the installation path, disk partition, driver entry and the like of the operating system through the cloud server installation interface, and the cloud management platform can execute the corresponding operating system installation process based on the custom installation operation of the tenant (i.e., the sixth operation).

[0010] In a possible implementation of the first aspect, the cloud management platform can automatically execute the installation process of the operating system and the corresponding driver according to an automatic answer file integrated in the ISO file, so that the installation process can be executed without the participation of the tenant. In a specific implementation, the cloud management platform can obtain an automatic answer file in the installation file of the operating system, and automatically install the operating system and the driver for the temporary cloud server based on the automatic answer file. The automatic answer file, for example, can be an unattend.xml file or the like, and can define the installation path, partition condition, driver entry and the like of the operating system.

[0011] In a possible implementation of the first aspect, the temporary cloud server can include at least two volumes, i.e., a first volume and a second volume. The first volume can include the operating system and the driver, and the cloud management platform can start the installation from the first volume, install the operating system and the driver in the first volume to the second volume, and set the startup mode of the operating system in the second volume to the hard disk startup when installing the operating system and the driver for the temporary cloud server.

[0012] In a possible implementation of the first aspect, the system disk image created by the cloud management platform can be a system disk image based on a Windows operating system or a Linux operating system. When creating the system disk image based on the Windows operating system, the cloud management platform can first obtain the original installation file uploaded by the tenant from the ISO file upload interface. The original installation file includes the Windows operating system, and since it usually does not include the driver required for installing the operating system, the cloud management platform can integrate the driver corresponding to the Windows operating system in the original installation file, and obtain the ISO file. Thus, the cloud management platform can create the private image based on the Windows operating system based on the ISO file integrated with the driver.

[0013] For example, the driver can be a Virtio driver.

[0014] When creating the private image based on the Linux operating system, the Virtio driver is usually included in the ISO file uploaded by the tenant, so the cloud management platform does not need to integrate the Virtio driver for the ISO file uploaded by the tenant.

[0015] In a second aspect, the embodiments of the present application further provide a device for creating a private image in a public cloud, characterized in that the device is applied to a cloud management platform on a network side, and the device comprises:

[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present specification, not all the embodiments.

[0034] In the description of the present specification, "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present specification. Thus, the appearance of the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in additional embodiments" and the like in various places in the present specification does not necessarily all refer to the same embodiment, but means "one or more but not all embodiments", unless otherwise specifically stated.

[0035] In the description of the present specification, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist together, and B exists alone. In addition, in the description of the embodiments of the present specification, "multiple" means two or more than two.

[0036] In the description of the present specification, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0037] At present, when making a private image, the cloud management platform usually converts the existing local image into a private image required by a tenant. Specifically, the existing local image can be registered as a private image through a private image import function, but it is not possible to create a private image for the tenant on the cloud management platform according to the ISO file provided by the tenant.

[0038] To this end, an embodiment of the present application provides a method for creating a private image in a public cloud. A cloud management platform at a network side can provide a plurality of interfaces to a tenant, including an ISO file uploading interface, an ISO image registration interface, a cloud server installation interface, a cloud server setting interface, and a cloud server image acquisition interface. The cloud management platform can obtain an ISO file uploaded by the tenant through the ISO file uploading interface. The ISO file carries an installation file of an operating system. The cloud management platform can register the ISO file as an ISO image of the public cloud according to a first operation input by the tenant through the ISO image registration interface. The ISO image carries the installation file of the operating system and registration information. Then, the cloud management platform can install the installation file of the operating system carried by the ISO image into a temporary cloud server according to a second operation input by the tenant through the cloud server installation interface. The cloud management platform can set a running environment in the operating system of the temporary cloud server according to a third operation input by the tenant through the cloud server setting interface. Thus, a temporary cloud server with the operating system installed can be obtained. The cloud management platform can obtain an image of the temporary cloud server with the running environment set according to a fourth operation input by the tenant through the cloud server image acquisition interface. The image is recorded as a system disk image of the public cloud for the tenant. The system disk image is used to provide the tenant to create a cloud server with the operating system and the running environment set in the public cloud. Thus, the cloud management platform can create a private image required by each tenant according to different ISO files provided for different tenants. Thus, the use experience of the tenant can be improved, and the actual application requirements of the tenant can be met.

[0039] The system disk image can be used as a private image of the tenant in the public cloud. That is, the tenant can quickly build a cloud service or a cloud application with the required operating system and running environment in a virtual machine, a container, or a bare metal server purchased by the tenant through the private image.

[0040] As an example, an embodiment of the present application can be applied to an application scenario as shown in Figure 1 . In the scenario, a cloud management platform 100 can provide an interactive interface 101. A tenant 200 can upload an ISO file and input related operations in the interactive interface 101. Thus, the cloud management platform 100 can install a cloud server according to an ISO image registered by the tenant 200. Thus, a private image expected by the tenant 200 can be further created according to the created cloud server. The cloud management platform 100 can be implemented by one or more computing devices 102 (one computing device 102 is taken as an example in Figure 1 . In actual application, the computing device 102 can be a server or the like providing a corresponding cloud service.

[0041] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, various non-limiting embodiments in the embodiments of the present application will be exemplarily described below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0042] Referring to Figure 2 , a flowchart of a method for creating a private image in a public cloud is shown, which can be applied to a cloud management platform 100 as shown in Figure 1 , and specifically can be applied to a device included in the cloud management platform 100 or a functional module on the device, and the following is taken as the cloud management platform 100 performing the creation. The method specifically can include:

[0043] S201: The cloud management platform 100 provides an ISO file upload interface, and obtains an ISO file uploaded by a tenant from the ISO file upload interface, wherein the ISO file carries an installation file of an operating system.

[0044] An image file refers to a series of specific files such as operating system files, boot program files and operating system startup mode files, which are made into a single file according to a certain format. In actual application, the image file can have multiple different formats, such as “.iso” format, “.ccd”, “.bwt” format, “.nrg” format, etc., and the ISO file in the present embodiment refers to an image file based on “.iso” format.

[0045] In some possible embodiments, the cloud management platform 100 can provide an interactive interface 101 as shown in Figure 1 , and the interactive interface 101 can include an operation button for uploading an ISO file. The tenant can click the corresponding operation button in the interactive interface 101 and upload the ISO file, and the ISO file at least includes an installation file of an operating system corresponding to the private image to be created, such as an installation file of a Windows operating system or a Linux operating system. Correspondingly, the cloud management platform 100 can provide an ISO file upload interface corresponding to the operation button, and obtain the ISO file uploaded by the tenant from the ISO file upload interface.

[0046] For example, the cloud management platform 100 can upload the ISO file uploaded by the tenant as an object to an Object Storage Service (OBS) bucket belonging to the tenant, for example, the cloud management platform 100 can store the ISO file in the OBS bucket through the OBS Browser+ tool. Of course, the specific implementation of uploading the ISO file and cloud storage of the ISO file by the cloud management platform 100 is not limited in the embodiment.

[0047] In actual applications, the cloud management platform 100 can receive an image file uploaded by the tenant in other formats, and therefore, in some examples, the cloud management platform 100 can add a type identifier of the image file, such as “Type = IsoImage”, to the ISO file uploaded by the tenant, so as to distinguish the ISO file from the image file in other formats. It is worth noting that the above-mentioned ISO file can be integrated with the driver corresponding to the operating system. Specifically, when the tenant expects to create a private image based on the Windows operating system on the cloud management platform 100, since the original installation file (which can only include the operating system) corresponding to the Windows operating system usually does not contain the driver required for installing the Windows operating system, such as the Virtio driver, the tenant can add the Virtio driver to the original installation file to obtain the ISO file, and then upload the ISO file integrated with the Virtio driver to the cloud management platform 100, such as the OBS bucket corresponding to the tenant. When the tenant creates a private image based on the Linux operating system, the original installation file corresponding to the Linux operating system usually already contains the Virtio driver, and therefore, the tenant can directly upload the original installation file (i.e., the ISO file) corresponding to the Linux operating system to the cloud management platform 100.

[0048] In addition, the cloud management platform 100 can also provide a setting interface, such as the setting interface shown in FIG. 11, for the tenant. The setting interface can include setting options for the system architecture of the temporary cloud server, such as the “X86” architecture type and the “ARM” architecture type in FIG. 11. The tenant can select whether the temporary cloud server runs on the “X86” platform or the “ARM” platform on the setting interface, such as the gray area in FIG. 11 representing that the tenant inputs (or selects) the architecture type as “X86”. The cloud management platform 100 can set the temporary cloud server to run on the “X86” architecture based on the selection operation of the tenant for the running environment. Figure 3 Figure 3 Figure 3

[0049] ​​​In a further possible implementation, the tenant can also select a startup mode of the operating system of the temporary cloud server, such as whether the tenant selects a "BIOS" startup or a "UEFI" startup of the operating system of the temporary cloud server in the setting interface (for example, the gray area in 3 represents that the tenant inputs (or selects) a "BIOS" startup mode). Wherein, "BIOS" refers to a Basic Input Output System, which is a set of fixed programs in a device, recording the basic input and output programs, self-checking programs after startup, and system self-starting programs, etc. (usually not supporting "BIOS" startup mode in ARM architecture). "UEFI" refers to a Unified Extensible Firmware Interface, which skips the self-checking process during startup, and the startup speed is usually faster than that of "BIOS".

[0050] In actual application, the tenant can also input more content on the setting interface, such as inputting which operating system in the ISO file is the operating system, and providing the version of the operating system to the cloud management platform 100; at the same time, the system disk size of the private image to be created (allowed to be between 40 GB and 1024 GB), the name of the private image, etc. can also be input on the input interface. Of course, Figure 3 The setting interface shown is only an exemplary illustration, and the setting interface presented in actual application can be of other styles, or the tenant can input more or less content on the setting interface, which is not limited in the embodiment.

[0051] S202: The cloud management platform 100 provides an ISO image registration interface, which is used to receive the first operation input by the tenant, and registers the ISO file as an ISO image of the public cloud according to the first operation, and the ISO image carries the installation file and registration information of the operating system.

[0052] In actual application, the cloud management platform 100 can register the ISO file uploaded by the tenant as an ISO image by using an image management service (IMS). Wherein, different from other images, the currently registered ISO image in the embodiment does not install an operating system, but carries the installation file of the operating system, so that the corresponding operating system can be installed for the registered ISO image subsequently. At the same time, the ISO image can also have corresponding registration information. Exemplarily, the registration information can be metadata generated when the ISO image is registered in the cloud management platform 100, such as the storage path of the ISO file and other metadata, and the cloud management platform 100 records the metadata.

[0053] In a specific implementation, the cloud management platform can provide an ISO image registration interface to the tenant. The tenant can input a first operation for implementing registration of an ISO image to the cloud management platform 100 through the ISO image registration interface. The first operation can be, for example, an operation (such as a click) that triggers the cloud management platform 100 to generate a registration instruction. Accordingly, the cloud management platform 100 can register the ISO file as an ISO image of the public cloud according to the first operation.

[0054] As an exemplary specific implementation, in the process of registering the ISO image, the cloud management platform 100 can specifically create an elastic compute service instance based on the ISO file, and call a Nova component in the cloud management platform 100 to assemble computing and storage resources for the elastic compute service instance, thereby implementing a temporary cloud server. At this time, the created temporary cloud server has not yet installed an operating system and related drivers.

[0055] Meanwhile, the cloud management platform 100 also includes a Cinder component that provides block storage services for the cloud management platform 100. The Cinder component can provide virtual disks (also referred to as volumes) for cloud servers. The Nova component can call the Cinder component to create at least two volumes for the temporary cloud server when creating the temporary cloud server. In this embodiment, a first volume and a second volume are created as an example.

[0056] The Cinder component can access the database in Glance through a Cinder driver, and find the download path and other metadata of the ISO file in the OBS bucket from the database according to the identifier of the ISO file, and download the ISO file from the OBS bucket based on the obtained metadata. As an example, the download path of the ISO file in the OBS bucket can record an IP address, an OBS bucket identifier (such as the name of the OBS bucket), an access port of the OBS bucket, and an object identifier stored in the OBS bucket, so that the Cinder component determines the IP address of the OBS bucket based on the download path, accesses a specific OBS bucket (determined according to the OBS bucket) through the corresponding OBS port, and accesses the object corresponding to the object identifier in the OBS bucket to obtain the ISO file.

[0057] Then, the Cinder driver can read the ISO file based on the obtained metadata and write it (or the operating system and drivers in the ISO file) into the first volume. At this time, the first volume carries the installation file of the operating system (including the driver), and the second volume is temporarily empty and is a blank volume.

[0058] In a further possible implementation, the cloud management platform 100 can also configure the availability zone, the specification, the cloud server name, the corresponding project name, the network card attribute, the network rule file for cleaning up the temporary cloud server, and the like, of the temporary cloud server in the process of registering the ISO image, so that the attributes of the temporary cloud server meet the requirements of the tenant. In actual application, the tenant can input an operation for configuring the temporary cloud server to the cloud management platform 100 through the cloud server configuration interface or other interfaces. For example, the cloud management platform 100 can present the configuration interface as shown in FIG. 6 to the tenant, so that the tenant performs corresponding configuration on the configuration interface. Further, the configuration interface can also present other information of the temporary cloud server to the tenant, such as the disk space size of the first volume (system disk) and the second volume (data disk) created and the configuration cost of the temporary cloud server this time. Figure 4

[0059] S203: The cloud management platform 100 provides a cloud server installation interface, which is used to receive a second operation input by the tenant, and installs the installation file of the operating system carried by the ISO image into the temporary cloud server according to the second operation.

[0060] Since the temporary cloud server created at present contains the ISO file, but the installation of the operating system is not completed, the cloud management platform 100 can further install the operating system for the temporary cloud server. Then, the cloud management platform 100 can provide a cloud server installation interface to the tenant, and the tenant inputs a second operation for installing the operating system to the cloud management platform 100 through the cloud server installation interface, which can be an operation (such as clicking a control for triggering the installation of the operating system, and the like) for triggering the cloud management platform 100 to install the operating system.

[0061] In an exemplary specific implementation, since the temporary cloud server usually does not contain an optical drive, in the process of writing the ISO file into the first volume, the boot mode of the operating system in the ISO file written into the first volume can be set as “cdrom”, so as to simulate the boot installation of the operating system from the cdrom optical drive, and the disk interface type used is “ide”. In this way, the Cinder driver can boot and install from the first volume, and install the operating system and the driver (such as Virtio driver, and the like) in the first volume into the second volume. In the installation process, the boot mode of the operating system in the second volume can be changed to “disk”, that is, the boot mode of the operating system installed in the second volume is set to boot from the hard disk, and the disk interface type corresponding to the second volume is also changed to “virtio”. In this way, the installation of the operating system and the driver for the temporary cloud server can be realized.

[0062] ​In actual application, in order to facilitate the Cinder component to start from the first volume first, the Cinder component can specify the start order of the volume when creating the first volume and the second volume. For example, the Cinder component can include the start order identifier, such as boot_index, in the created volume, and the Cinder component can start from the first volume according to the start order identifier, so as to install the operating system and the driver in the first volume to the second volume. For example, the Cinder component can assign the start order identifier boo_index of the first volume as 0, and assign the start order identifier boo_index of the first volume as 1, and correspondingly, the Cinder component can start from the volume with boo_index = 0 by default. Of course, the embodiment is not limited to the specific implementation manner of starting the first volume first.

[0063] It is worth noting that in the above embodiment, the Cinder component creates the first volume and the second volume at the same time, and in actual application, the Cinder component can create the first volume first, and then create the second volume after successfully downloading the ISO file from the OSB bucket, and the embodiment is not limited thereto.

[0064] When installing the operating system and the driver, the cloud management platform 100 can be installed by the tenant participating in the installation process, such as specifying the installation path of the operating system, or can be automatically installed by the cloud management platform 100 based on the second operation.

[0065] In the implementation manner in which the tenant participates in the installation of the operating system and the driver, the tenant can also input the sixth operation through the cloud server installation interface, and the cloud management platform 100 can determine how to install the operating system and the corresponding driver based on the sixth operation. For example, the cloud management platform 100 can provide an installation definition interface to the tenant. The tenant can remotely define the installation of the operating system on the installation definition interface, such as defining the installation path, disk partition, disk naming, etc. of the operating system in the temporary cloud server, and the sixth operation can be the selection or input operation of the tenant for the disk partition, installation path, and driver item to be installed of the operating system. In this way, the cloud management platform 100 can obtain the installation definition operation of the tenant for the operating system, and install the corresponding operating system for the temporary cloud server according to the installation definition operation.

[0066] In the above embodiment, the tenant participates in the installation of the operating system and the driver, so that the cloud management platform 100 needs to determine the installation information of the operating system and the driver, such as the disk partition, the installation path, and the driver item, based on the sixth operation input by the tenant, so that the tenant needs to be on duty. Correspondingly, in other possible embodiments, the cloud management platform can also automatically install the operating system and the driver.

[0067] In a specific implementation, the tenant uploads an ISO file integrated with an automatic response file (such as an unattend.xml file, etc.), so that the cloud management platform 100 can start the automatic response file during the installation of the operating system and the driver, and automatically determine the installation path of the operating system, the partition condition, and which driver to install based on the automatic response file, so that the installation process of the operating system and the driver can be performed without the participation of the tenant, and a full-automatic installation process without manual intervention is realized. For example, for a Windows system, an unattend.xml file can be integrated in the ISO file, and for Linux, an AutoYaST or Kickstart file can be integrated in the ISO file. Of course, in actual applications, other ways can also be used to realize the automatic installation of the operating system and the driver, and the present embodiment does not limit this.

[0068] S204: The cloud management platform 100 provides a cloud server setting interface, which is used to receive a third operation input by the tenant, and sets a running environment in the operating system of the temporary cloud server according to the third operation.

[0069] In actual applications, different cloud servers can be in different running environments, and therefore, the cloud management platform 100 can set a corresponding running environment for the created temporary cloud server, which can be set by the tenant. In a specific implementation, the cloud management platform 100 can provide a cloud server setting interface for the tenant; the tenant can input a third operation for setting a running environment to the cloud management platform 100 through the cloud server setting interface, so that the cloud management platform 100 can set a running environment for the temporary cloud server based on the third operation.

[0070] In some examples, the cloud management platform 100 can specifically configure corresponding software in the operating system of the temporary cloud server, such as office software, drawing software, or other software customized by the tenant, etc., so as to complete the configuration of the running environment in the operating system.

[0071] It is worth noting that the present embodiment does not limit the specific execution order of step S204 and step S203 in actual applications. That is, in other embodiments, the running environment setting process in step S204 can be performed first, and then the operating system installation process in step S203 can be performed, or the cloud management platform can also perform step S204 and step S203 at the same time.

[0072] S205: The cloud management platform 100 provides a cloud server image acquisition interface, which is used to receive a fourth operation input by the tenant, and acquire an image of a temporary cloud server provided with the running environment according to the fourth operation, and record the image as a system disk image of the tenant in the public cloud, wherein the system disk image is used to provide the tenant to create a cloud server provided with an operating system and a running environment in the public cloud.

[0073] The obtained system disk image can be used as a private image of the tenant in the public cloud, so that the user can quickly build a cloud service or cloud application provided with the required operating system and running environment of the user in the public cloud through the private image.

[0074] After the temporary cloud server is installed and the setting of the running environment is completed, the operating system and the driver on the temporary cloud server can meet the expectations of the tenant, and then the cloud management platform 100 can create a private image required by the tenant based on the temporary cloud server. Specifically, the second volume of the temporary cloud server can be exported as an image file, and the private image required by the tenant can be created based on the image file exported by the second volume. The private image has already installed an operating system and corresponding drivers, and can be used as a template to be distributed to the tenant.

[0075] In a specific implementation, the Cinder component can export the data (including the operating system, the driver, etc.) in the second volume into an image file, and place the image file in the OBS bucket for storage. Meanwhile, the metadata inherited from the ISO file saved in the first volume, such as the name of the image file, the type of the operating system, the installed driver, the identification of the private image, and other data metadata, is inherited. It is worth noting that the Cinder component can also update the metadata inherited from the first volume. For example, the metadata corresponding to the original ISO file may include metadata of the startup mode “cdrom”, but the operating system in the current ISO file has been installed in the second volume, and the temporary cloud server does not need to install the operating system from the cdrom again, so the metadata (i.e., “cdrom”) in the ISO file does not need to be retained. Accordingly, the metadata can be deleted in the process of inheriting the metadata from the first volume. Of course, in actual applications, the metadata updated by the Cinder component adaptively can also include other metadata (such as the disk interface type corresponding to the ISO file needs to be updated from “ide” to “disk”), which can be determined according to the needs in actual applications, and this embodiment will not be described here.

[0076] It is worth noting that since the ISO file can be stored in the OBS bucket, and the ISO file can be directly obtained from the OBS bucket in the process of creating the private image, without the need to store the ISO file locally in the node supporting the cloud management platform in advance, thus, not only the storage space of the node can be reduced, but also since the ISO file can not be stored locally, the problem that the live migration of the temporary cloud server cannot be implemented because the temporary cloud server needs to carry the local ISO file can be avoided.

[0077] In a further possible implementation, after the cloud management platform 100 creates the private image desired by the tenant, the cloud management platform 100 can delete the temporary cloud server generated in the process of creating the private image, so as to release the resources occupied by the temporary cloud server. Therefore, in the present embodiment, the method can further include:

[0078] S206: The cloud management platform 100 provides a cloud server deletion interface, which is used to receive the fifth operation input by the tenant and delete the temporary cloud server according to the fifth operation.

[0079] In this way, the resources occupied by the temporary cloud server can be released, and unnecessary occupation and waste of cloud server resources can be avoided.

[0080] Based on the method of creating a private image by the cloud management platform, the present embodiment further provides an apparatus for creating a private image in a public cloud.
