Description

Technical Field

[0001] This invention relates to the field of IT and software development technology, and in particular to a method, apparatus, electronic device and storage medium for customizing proprietary images. Background Technology

[0002] User images are a crucial factor. On one hand, they form the foundation for meeting users' needs for instance operating systems. Providing high-quality, secure, easy-to-use, and stable images, along with numerous options, significantly improves the user experience. On the other hand, they are an integral part of resource management; the generation, storage, and downloading of images directly impact the efficiency and quality of the entire delivery process. Furthermore, an increasing number of users have customized needs when standard user images fail to meet their requirements, further complicating image provision and processes. Currently, simplifying image provision and processes remains a challenge. Summary of the Invention

[0003] This invention provides a private image customization method, apparatus, electronic device, and storage medium. The PXE environment and Agent program customized for bare-metal platforms can identify most mainstream storage hardware, disk partitions, and file systems. It can accurately obtain system partition layout information and supports outputting various image files, including squashfs format, along with partition layout information. It can not only copy the user's partition layout but also ensure the high efficiency of application images.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Firstly, a private image customization method is provided for use in bare-metal systems. The method includes: responding to an image save operation and restarting the PXE system; the PXE system identifying the disk partitions and file system of the bare-metal instance; performing image verification based on the disk partitions and file system; and generating an image file if the image verification passes.

[0006] As can be seen from the method described in the first aspect, the present invention restarts the PXE system in response to the image saving operation. The PXE system identifies the disk partitions and file system of the bare metal instance and performs image verification based on the disk partitions and file system. If the image verification passes, an image file is generated, thereby ensuring that even under complex operating procedures, the output user image can run normally on the same hardware environment.

[0007] In conjunction with the first aspect, in one possible design scheme, before performing image verification based on the disk partitions and the file system, the steps include: reading the partition mount configuration and executing the mounting of all partitions in the chroot tool and environment; and executing the mounting of all partitions in the chroot tool and environment.

[0008] Based on this possible design scheme, it can be seen that it can identify most mainstream storage hardware, disk partitions and file systems, and can accurately obtain system partition layout information.

[0009] In conjunction with the first aspect, in one possible design scheme, the image verification based on the disk partition and the file system includes: verifying the integrity of the target user image content, the configuration items and security configurations required by the bare-metal platform, the file system and device drivers in a chroot environment; if the verification passes, it is determined that the image can be installed and used in the same hardware environment; if the verification fails, the steps of verifying the image based on the disk partition and the file system are repeated.

[0010] Based on the possible design schemes, it is known that the reliability of the user image can be guaranteed.

[0011] In conjunction with the first aspect, in one possible design scheme, generating an image file if the image verification passes includes: copying and compressing system files and generating an image file according to a preset format if the image verification passes.

[0012] Based on the possible design schemes, it is known that it can support the output of various image files, including squashfs format, and include partition layout information. It can not only copy the user's partition layout, but also ensure the high efficiency of application images.

[0013] In conjunction with the first aspect, in one possible design scheme, the method further includes: acquiring the image file and sending the image file to an image service management platform, wherein the image service provides image download services internally; storing the image file and determining a download address based on the image file; and publishing the download address.

[0014] Based on the possible design schemes, it can be seen that this embodiment has almost no other external dependencies except for being published to an external distributed storage, requires no manual intervention, and has a high degree of automation.

[0015] In conjunction with the first aspect, in one possible design scheme, the method further includes: receiving a DHCP request and determining the IP address, lease, and system boot file name based on the DHCP request; requesting a TFTP service based on the IP address, the lease, and the system boot file name; booting the PXE system based on the feedback information from the TFTP service request; and uploading the boot image configuration to an image service via HTTP to complete image customization.

[0016] Based on possible design schemes, it can be seen that the customized PXE environment and Agent program on the bare metal platform can identify most mainstream storage hardware, disk partitions and file systems, and can accurately obtain system partition layout information.

[0017] In conjunction with the first aspect, in one possible design scheme, the method further includes: obtaining an image boot instruction; determining, based on the image boot instruction, the relevant services, drivers, and configurations corresponding to the image service in the bare metal system; and saving the image based on the relevant services, drivers, and configurations corresponding to the image service.

[0018] Based on the possible design schemes, it can be seen that the PXE environment is a temporary environment and does not have the ability to store images. The generated images will be transferred to the bare metal management platform image service, which only provides image download services internally to improve reliability.

[0019] Secondly, a private image customization device is applied to a bare-metal system. The device includes: a response module for responding to an image saving operation and restarting the PXE system; an identification module for the PXE system to identify the disk partitions and file system of the bare-metal instance; an image verification module for verifying the image based on the disk partitions and the file system; and an image file generation module for generating an image file if the image verification passes.

[0020] Furthermore, the technical effects of the private image customization device described in the second aspect can be referenced from the technical effects of the distributed caching method described in the first aspect, and will not be repeated here.

[0021] Thirdly, embodiments of the present invention provide an electronic device. The electronic device includes a processor and a memory; the memory stores a computer program, which, when executed by the processor, causes the electronic device to perform the method described in any of the implementations of the first aspect.

[0022] Fourthly, embodiments of the present invention provide a computer-readable storage medium, comprising: a computer program or instructions; when the computer program or instructions are executed on a computer, causing the computer to perform the method described in any possible implementation of the first aspect.

[0029] The technical solution of the present invention will now be described with reference to the accompanying drawings.

[0030] In embodiments of the present invention, words such as "exemplarily," "for example," etc., are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in embodiments of the present invention, the meaning expressed by "and / or" can be both, or either one.

[0031] In the embodiments of this invention, the terms "image" and "picture" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, their intended meanings are consistent. Similarly, the terms "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, their intended meanings are consistent.

[0032] The image customization process is complex, prone to errors, and cumbersome in its verification, generally requiring significant manual intervention. Furthermore, compared to virtual machine services, providing private image customization for bare metal platforms is more challenging and more susceptible to serious issues caused by missing drivers or misconfigurations. Building upon the current stable and reliable bare metal platform infrastructure, and by fully utilizing management service capabilities, network capabilities, and storage capacity, this patent proposes a feasible, reliable, and verifiable method for customizing private images on a bare metal platform. This method will provide platform users with reliable services such as private image customization, image uploading and publishing, and platform deployment, with the main processes initiated and automatically completed by the user on the platform.

[0033] Therefore, in order to overcome the above-mentioned defects, embodiments of the present invention provide a private image customization method, device, electronic device, and readable storage medium. Through the solution of the present invention, the PXE environment and Agent program customized for the bare metal platform can identify most mainstream storage hardware, disk partitions and file systems, accurately obtain system partition layout information, support output of various image files including squashfs format, and include partition layout information. It can not only copy the user's partition layout, but also ensure the high efficiency of application images.

[0034] Please see Figure 1 , Figure 1 This is a flowchart illustrating a distributed caching method provided in an embodiment of the present invention. This method can be executed by an electronic device with processing capabilities, such as a server or cloud server, without specific limitations. The method is applied to a distributed hierarchical caching system, and specifically includes steps 210 to 240.

[0035] Step 210: Respond to the image save operation and restart the PXE system.

[0036] Step 220: The PXE system identifies the disk partitions and file system of the bare metal instance.

[0037] Step 230: Perform image verification based on the disk partition and the file system.

[0038] Step 240: If the image verification passes, an image file is generated.

[0039] In some embodiments, such as Figure 4 As shown, a stable and reliable method for customizing private images is proposed. This method mainly includes the following steps:

[0040] S1, the user calls the bare metal management platform API to create a bare metal instance containing the base image of the target image;

[0041] S2, the user executes a customization process, in which the user adds relevant services, drivers, configurations and other changes according to their own needs, which can be completed by an automated script;

[0042] S3, User image customization is complete, and the user triggers the image save operation;

[0043] S4, the bare-metal instance performs a reboot operation and enters the PXE system state. The special feature of this PXE image is that, in addition to containing the environment for a normal boot system, it includes an Agent program capable of executing a series of operational commands (such as...). Figure 3 ) and a set of tools that work in conjunction with instructions;

[0044] S5, the PXE system identifies the user's bare metal instance disk partitions and file systems, reads the partition mount configurations contained in / etc / fstab, and executes the mount of all partitions in the chroot tool and environment;

[0045] S6, the image verification program, in a chroot environment, verifies the integrity of the target user image content and the configuration items required by the bare-metal platform (such as serial port, kernel parameters, etc.), security configuration, file system, and device drivers. If the verification is successful, it means that the user image can be installed and used in the same hardware environment; otherwise, the process cannot guarantee the reliability of the user image.

[0046] S7 outputs a user image based on the settings for the output user image format. The output format can be squashfs (default), qcow2, raw, etc. At the same time, it will generate a partition layout file based on the current mount status. This file will retain the user system partition scheme and apply it to the installation of the new instance.

[0047] The S8 PXE environment is a temporary environment and does not have the ability to store images; the generated images will be transferred to the bare metal management platform image service, which only provides image download services internally.

[0048] After receiving the user's image, the S9 image service will synchronously upload it to object storage services such as S3 and provide the user with a download address;

[0049] S10 allows users to rename the target image and configure it on the bare metal management platform for subsequent verification and application.

[0050] This embodiment has the following beneficial effects: 1. The PXE environment and Agent program customized for the bare metal platform can identify most mainstream storage hardware, disk partitions and file systems, and can accurately obtain system partition layout information;

[0051] 2. Supports outputting various image files, including squashfs format, with partition layout information. It can not only copy the user's partition layout, but also ensure the high efficiency of application images.

[0052] 3. The introduction of automated verification processes can ensure that even under complex operating procedures, the output user images can run normally on the same hardware environment;

[0053] 4. The core processes throughout the entire procedure can be automated by executing commands.

[0054] This invention restarts the PXE system in response to an image save operation. The PXE system identifies the disk partitions and file system of the bare metal instance and performs image verification based on the disk partitions and file system. If the image verification passes, an image file is generated, thereby ensuring that even under complex operating procedures, the output user image can run normally on the same hardware environment.

Figure 5 As shown, the distributed caching device 600 includes: a response module 610, an identification module 620, an image verification module 630, and an image file generation module 640.

[0057] Furthermore, before performing image verification based on the disk partitions and the file system, the process includes: retrieving the partition mount configuration and mounting all partitions in the chroot tool and environment; and mounting all partitions in the chroot tool and environment.

[0058] Furthermore, the image verification based on the disk partition and the file system includes: verifying the integrity of the target user image content, the configuration items and security configurations required by the bare metal platform, the file system and device drivers in a chroot environment; if the verification passes, it is determined that the image can be installed and used in the same hardware environment; if the verification fails, the steps of verifying the image based on the disk partition and the file system are repeated.

[0059] Furthermore, the step of generating an image file if the image verification passes includes: copying and compressing system files and generating an image file according to a preset format if the image verification passes.

[0060] Furthermore, the device further includes: acquiring the image file and sending the image file to an image service management platform, wherein the image service provides image download services internally; storing the image file and determining a download address based on the image file; and publishing the download address.

[0061] Furthermore, the device further includes: receiving a DHCP request and determining an IP address, a lease, and a system boot file name based on the DHCP request; requesting a TFTP service based on the IP address, the lease, and the system boot file name; guiding PXE startup based on the feedback information from the TFTP service request; and uploading the boot image configuration to an image service via HTTP to complete image customization.

[0062] Furthermore, the device further includes: acquiring an image boot command; determining, according to the image boot command, the relevant services, drivers, and configurations corresponding to the image service in the bare metal system; and saving the image according to the relevant services, drivers, and configurations corresponding to the image service.
