Description
Technical Field
The present application relates to the field of mirror deployment technologies, and in particular, to a method, an apparatus, and a medium for bare metal mirror deployment.
Background
With the continuous development of server virtualization technology, traditional data center services are gradually migrating to the cloud. However, for some heavy-duty traffic, such as databases and the like, there is still a need to be deployed in bare metal infrastructure, where bare metal refers to computer hardware without an operating system, to meet the high performance, low latency requirements of the heavy-duty traffic.
In bare metal system deployment, an operating system image to be deployed is usually installed and manufactured in advance, and uploaded to an image warehouse in a reduced qcow2 format. During deployment, the operating system image is downloaded to the bare metal server from the image warehouse, converted into a raw format and released to a local hard disk, so that quick deployment is completed.
Specifically, openstack Ironic-frame bare metal system deployment has two implementations. One possible implementation method is that a local disk on a bare metal server is mounted to a Ironic control node according to an iSCSI protocol, the Ironic control node downloads an operating system image in qcow2 format from an image warehouse, and the operating system image in qcow2 format is copied to a mounted remote bare metal server hard disk after being converted into a raw format, so that deployment is completed.
In another possible implementation, unlike the above-mentioned transmission of the os image based on iSCSI protocol, the method starts a proxy service HTTP SERVER after the control node converts the qcow2 format os image into the raw format at Ironic, and remotely requests to download the raw format os image at the bare metal server through a client request tool HTTP CLIENT, and copies the raw format os image to the local hard disk of the bare metal server, thereby completing deployment.
In the deployment process of the bare metal system, the two embodiments need to convert the qcow2 format operating system image into the raw format at Ironic control nodes and then transmit the raw format operating system image to the bare metal server. The image capacity of the raw format operating system is often large, so that a lot of network bandwidth resources are occupied in the transmission process, the transmission time is long, and the deployment efficiency is low.
Therefore, how to reduce the occupation amount of network bandwidth resources in bare metal deployment and improve the deployment efficiency is a technical problem to be solved by those skilled in the art.

In the development process of automobiles, it is required to verify the performance of the automobile through a Computer aided engineering (Computer AIDED ENGINEERING, abbreviated as CAE) simulation platform, for example, to verify the comfort of the chassis of the automobile, and to evaluate the strength, rigidity, fatigue durability, NVH (noise, vibration and harshness) characteristics and the like of automobile structural components (such as automobile bodies, frames, suspension systems and the like) under static loads (such as dead weights) and dynamic loads (such as collisions, road impacts, torsion and the like). Specifically, when the performance of the vehicle is verified by the CAE simulation platform, an operating system needs to be installed on the physical server, that is, an operating system mirror image needs to be deployed on the bare metal (physical server) so as to implement the CAE simulation on the physical server.
When the mirror image deployment of bare metal is carried out, how to reduce the occupation amount of network resources during the mirror image transmission and improve the mirror image deployment efficiency is an important research direction. In order to solve the technical problems, the embodiment of the application provides a bare metal mirror deployment method, which delays the conversion of a mirror format to a bare metal service node, namely to a physical machine server, so that network resources are saved and the mirror deployment efficiency is improved.
Fig. 1 is a flow chart of a method for bare metal mirror deployment according to an embodiment of the present application, as shown in fig. 1, the method includes:
S10: receiving a first mirror image in a first format sent by a bare metal control node;
Fig. 2 is a schematic block diagram of a bare metal mirror deployment according to an embodiment of the present application, as shown in fig. 2, in a specific embodiment, a bare metal control node 2 downloads a first mirror in a first format from a mirror warehouse 1, and sends the first mirror to a bare metal service node 3.
In some alternative embodiments, since the qcow2 format image is easy to archive and distribute, the first format of the first image may be qcow2 format image, or may be an image of other formats, which is not limited to this application. It should be noted that, the method for deploying the bare metal mirror images provided by the application can be used for deploying the mirror images of a plurality of bare metals at the same time.
S11: converting the first image into a second image in a second format; the storage space occupation amount of the first mirror image is smaller than that of the second mirror image;
Further, after the bare metal service node 3 receives the first image in the first format sent by the bare metal control node 2 through step S10, it is to be understood that, in order to reduce the excessive network resources occupied by the image in the transmission process, the storage space occupation amount of the first image is smaller than that of the second image.
In some alternative embodiments, the second mirror is a raw format mirror, i.e., a format mirror necessary for the bare metal service node 3 to function properly. It will be appreciated that the raw format mirror image storage space occupies a relatively large amount, for example, a first mirror image in qcow2 format that occupies 10 Gigabytes (GB) of real storage space may be calibrated to a second mirror image in raw format of 100GB, i.e. a first mirror image in qcow2 format of 10GB may be converted to a second mirror image in raw format of 100 GB.
Therefore, if the bare metal control node 2 converts the first image into the second image, the second image is transmitted to the bare metal service node 3 for deployment, more network bandwidth resources are occupied in the transmission process, and the time consumption of transmission is increased, so that the conversion of the first image in qcow2 format into the second image in raw format is completed in the bare metal service node 3, thereby saving network resources.
S12: and deploying the second mirror image to the local hard disk.
Further, the second mirror image is deployed to the local hard disk of the bare metal service node 3, so that the mirror image deployment of the bare metal is completed, and network resources and storage space are saved through simplified transmission and delay conversion.
Therefore, the method for deploying the bare metal mirror image provided by the embodiment of the application finishes the format conversion and deployment of the mirror image at the bare metal service node 3, avoids the situation that more network resources are occupied due to the fact that the bare metal control node 2 converts the first mirror image with smaller storage space occupation into the second mirror image with larger storage space occupation, delays the conversion and deployment of the mirror image format to the bare metal service node 3, can reduce the network bandwidth occupation, reduces the mirror image transmission time length, and further improves the deployment efficiency of the bare metal mirror image.
In an alternative embodiment, the first image is a compressed image in a predetermined manner; the preset mode comprises a zip compression mode. On the basis of the above embodiment, in order to further reduce network resources occupied by the first image in the transmission process, the first image is compressed, and specifically, a qcow2 format is taken as an example for explaining the first format.
After the bare metal control node 2 downloads the first mirror image in qcow2 format from the mirror image warehouse 1, the first mirror image in qcow2 format is zip-compressed, and the compressed first mirror image is transmitted to the bare metal service node 3, and it is noted that the first mirror image obtained by the bare metal service node 3 is the mirror image in qcow2 format and is the mirror image after zip compression.
For example, the first mirror image in the qcow2 format of 10GB is compressed into the first mirror image in the qcow2 format of 2GB, so that occupation of network resources when the bare metal control node 2 transmits the first mirror image can be further saved, the transmission rate is improved, and the mirror image deployment efficiency of the bare metal is improved.
In fact, the preset compression mode of the first mirror image is not limited, and the zip compression mode is preferable to compress the first mirror image because the zip compression mode can compress the first mirror image to obtain the mirror image with smaller occupied storage space.
Thus, the reduced qcow2 format is maintained and compressed before the bare metal control node 2 is ready to distribute the transmission first image to the bare metal service node 3, the dual measure reducing the transmission disk capacity.
It can be understood that, based on the above embodiment, after the compressed first image is transmitted to the bare metal service node 3, the bare metal service node 3 needs to decompress the first image first and then convert the first image into the second image in the second format.
Specifically, taking the first format as qcow2 format and the second format as raw format as an example for explanation, the bare metal control node 2 compresses the first mirror image of the qcow2 format of 10GB into the first mirror image of the qcow2 format of 2GB, and then transmits the first mirror image to the bare metal service node 3, and the bare metal service node 3 decompresses the first mirror image of the qcow2 format of 2GB into the first mirror image of the qcow2 format of 10GB based on the manner of unzip decompression.
Further, the first image in the qcow2 format of 10GB is converted into the second image in the raw format through the qemu-img tool. Wherein qemu-img is a command line tool that is part of the simulation processor QEMU (Quick Emulator) virtualization software suite for creating, converting, and managing disk image files.
Notably, in some alternative embodiments, bare metal control node 2 may be Ironic control node, ironic is an item in the Open source community-pushed Open Stack architecture for managing bare metal service node 3.
In this way, in the method for deploying the bare metal mirror image provided by the embodiment of the application, the bare metal control node 2 compresses the first mirror image and transmits the compressed first mirror image to the bare metal service node 3, the bare metal service node 3 completes decompression and format conversion of the first mirror image, and deploys the second mirror image obtained by format conversion to the local hard disk, so that the deployment of the bare metal mirror image is realized, and the occupation amount of the mirror image to network resources in the transmission process is further saved. In addition, the compression mode is adopted to store the mirror image, so that the occupation of the local storage space can be reduced.
In an alternative embodiment, in order to further improve the mirror image deployment efficiency of the bare metal and reduce the storage space occupation amount, the method for deploying the mirror image of the bare metal provided by the embodiment of the application decompresses the first mirror image, converts the first mirror image into a second mirror image in a second format, and deploys the second mirror image on a local hard disk, including:
For the data in the first mirror image and the second mirror image, sequentially decompressing the data in the first mirror image in a streaming data processing mode, converting the decompressed data into the data in the second mirror image, and deploying the data of the second mirror image on a local hard disk.
It can be understood that if the compressed first image is decompressed and stored, then the decompressed first image is converted into the second image for storage, and finally the second image is deployed on the local hard disk, more storage space is occupied, and the deployment efficiency of the images is low.
Therefore, according to the technical scheme provided by the embodiment of the application, the first mirror image is decompressed in turn in a non-falling mode, namely in a streaming data processing mode, while the bare metal service node 3 receives the compressed first mirror image, the decompressed first mirror image is converted into the second mirror image, and the second mirror image is deployed on the local hard disk.
That is, the first mirror image is decompressed and then is not stored, and is directly converted into a second mirror image in a second format, and the second mirror image is not stored after being obtained, and is directly deployed on a local hard disk, so that the occupation amount of the storage space of the bare metal service node 3 is reduced, and the deployment efficiency of bare metal is improved.
In some alternative embodiments, converting the first image to a second image in a second format includes:
downloading a virtual memory disk from the bare metal control node through a pxe boot technology;
A proxy service is initiated in the virtual disk to convert the first image to the second image via the proxy service.
In particular embodiments, when converting the first image to a second image in the second format, the virtual memory disk (ramdisk) may be downloaded from the bare metal control node 2 via a preset network boot technique, which in some alternative embodiments includes, but is not limited to, a px boot technique.
Further, the bare metal service node 3 initiates a proxy service in the virtual disk (HTTP SERVER) by which the first image is converted to the second image by the qemu-img tool.
In some alternative embodiments, the proxy service converts the first image to a second image, comprising:
Dividing a storage space with a preset size in a virtual memory disk;
and converting the first mirror image into a second mirror image in a storage space with a preset size.
Specifically, the proxy service HTTP SERVER divides a storage space of a predetermined size in the virtual disk ramdisk to convert the first image into the second image in the storage space. Further, the proxy service HTTP SERVER continuously writes the converted second image data in the second format into the local hard disk in an asynchronous manner, thereby completing the image deployment of the bare metal.
In the foregoing embodiment, a detailed description is given of a bare metal mirror deployment method applied to a bare metal service node, and the embodiment of the present application further provides a corresponding embodiment of a bare metal mirror deployment method applied to a bare metal control node, where the method includes:
the method comprises the steps that a first mirror image in a first format is sent to a bare metal service node, so that the bare metal service node converts the first mirror image into a second mirror image in a second format, and the second mirror image is deployed on a local hard disk; the storage space occupation amount of the first mirror image is smaller than that of the second mirror image.
It can be understood that the deployment method of the bare metal control node side provided by the embodiment of the application corresponds to the deployment method of the bare metal service node side, so that the beneficial effects are the same, and the description is omitted here.
