Detailed Description
In the cloud computing era, along with the continuous expansion of the internet market scale, a large amount of heterogeneous resources are uniformly managed through a cloud platform. When a virtual machine is created on a cloud platform, a local mirror image needs to be uploaded to the cloud platform.
The current mirror image uploading flow is shown in fig. 1, and specifically may include the following 4 steps:
(1) The mirror image stored locally by the user is uploaded to the UI module of the cloud platform through the uploading interface and the management network, and the middle of the mirror image is subjected to gateway shunting, authority authentication and other operations.
(2) And (3) forwarding the data stream checked in the step (1) to the cloud platform IMAGE module through the management network by the UI module of the cloud platform.
(3) And after the IMAGE file is cached by the cloud platform IMAGE module, calling a GLANCE interface of the OPENSTACK through the management network, and uploading the IMAGE to a GLANCE control node. The process requires an INGRESS forwarding of OPENSTACK and KEYSTONE authentication.
(4) The GLANCE control node stores the mirror image to the configured storage node and completes the mirror image registration in the database.
The prior mirror last approach described above has three drawbacks: when the mirror image is larger, the call speed of the cloud management platform interface can be influenced by managing the network flow; secondly, the time consumption of the uploading process is relatively high because the middle is subjected to four data carrying processes; thirdly, if the user turns off the browser carelessly in the uploading process or interrupts the uploading process, the user needs to upload again from the beginning, which also results in poor user experience. Therefore, how to optimize the uploading process of the virtual machine image so that the virtual machine image can be quickly imported into the storage node of the database is a problem to be solved at present.
In order to solve the above-mentioned drawbacks, the present embodiment provides a method for fast importing a virtual machine image, which includes determining a target virtual machine image first, uploading the target virtual machine image to an object storage, uploading an empty image corresponding to the target virtual machine image through a cloud platform, creating an empty image file in a storage node according to the empty image, storing attribute information and metadata information of the target virtual machine image in a database, and copying the target virtual machine image from the object storage to the empty image file of the storage node. Therefore, the virtual machine image can be directly uploaded to the object storage through the storage network, when the cloud platform uploads the virtual machine image, the image data stream transmission link is reduced, the uploading time is shortened, meanwhile, the management network traffic is not occupied, the image uploading success rate is improved, the quick and efficient uploading of the virtual machine image is realized, and the user experience is improved.
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
First embodiment
Referring to fig. 2, a flowchart of a method for fast importing a virtual machine image according to the present embodiment is provided, where the method includes the following steps:
s201: and determining a target virtual machine image, and uploading the target virtual machine image to the object storage.
It should be noted that in the current distributed storage area, there are three disadvantages to the mirror image upload flow shown in fig. 1: when the mirror image is larger, the call speed of the cloud management platform interface can be influenced by managing the network flow; secondly, the time consumption of the uploading process is relatively high because the middle is subjected to four data carrying processes; thirdly, if the user turns off the browser carelessly in the uploading process or interrupts the uploading process, the user needs to upload again from the beginning, which also results in poor user experience.
Therefore, in this embodiment, in order to achieve fast and efficient uploading of the virtual machine image, so as to improve the user experience, the target virtual machine image is first determined, and the target virtual machine image is uploaded to the object storage, so as to continuously execute the subsequent steps S202 and S203.
Object storage refers to mass internet storage of object/file oriented, and can also be directly called as 'cloud storage'. The object is a file, but is a file already encapsulated (the object in programming has the characteristic of encapsulation), that is, in the object storage system, the file cannot be directly opened/modified, but the file can be uploaded, downloaded and the like ftp. In addition, the object storage does not have a file structure with a plurality of levels like a file system, but only has a concept of a bucket (i.e. a storage space), and all the inside of the bucket is an object, so that the object storage is a very flattened storage mode. The biggest feature is that its object name is a domain name address, which can be accessed by all users once the object is set to "public"; its owner may also access objects therein by way of a REST API. Thus, the object stores a more mainstream usage scenario, namely, stores static content (video, picture, file, software installation package, etc.) of internet/mobile internet applications such as websites, mobile apps, etc.
Whereas OpenStack in fig. 1 refers to an open-source cloud computing management platform item.
An optional implementation manner, the implementation process of "upload target virtual machine image to object store" in step S201 may specifically include: and directly uploading the target virtual machine mirror to the object storage through the storage network by using the Amazon S3 interface.
Specifically, in the implementation manner, after the target virtual machine image which needs to be uploaded by the user is determined, the target virtual machine image which needs to be uploaded is directly uploaded to the object for storage through the storage network through the Amazon S3 interface, and the transmission speed is high because the bandwidth of the storage network is relatively large and the process data stream does not pass through other forwarding and shunting.
Wherein Amazon S3 refers to an acronym for Amazon Simple Storage Service, which is also an internet storage solution. The service aims to reduce the difficulty of network scale level computation for developers. Amazon S3 provides a simple Web service interface that can be used to store and retrieve any amount of data anywhere on the Web at any time. The service enables all developers to access the same data storage infrastructure with high expansibility, reliability, security and rapidness and low cost.
S202: uploading an empty mirror image corresponding to the target virtual machine mirror image through the cloud platform, creating an empty mirror image file in the storage node according to the empty mirror image, and storing attribute information and metadata information of the target virtual machine mirror image into a database.
In this embodiment, in order to reduce the transmission link of the target virtual machine image, shorten the uploading time, and meanwhile, not occupy the management network traffic, improve the uploading success rate of the target virtual machine image, after the target virtual machine image is uploaded to the object storage in step S201, further, an empty image corresponding to the target virtual machine image may also be uploaded through the cloud platform, and an empty image file may be created in the storage node according to the empty image, and attribute information (such as the memory size, the hard disk size, and other attribute information required for creating the operating system by using the virtual machine image) and metadata information of the target virtual machine image may be saved in the database, so as to execute the subsequent step S203.
In an alternative implementation manner, the specific implementation process of the step S202 may include the following steps a-D:
step A: uploading an empty mirror image corresponding to the target virtual machine mirror image through the cloud platform, acquiring an information flow corresponding to the target virtual machine mirror image according to the empty mirror image, and uploading the information flow to a UI server of the cloud platform after ingress load splitting and gateway authentication.
In the implementation mode, when the empty mirror image corresponding to the target virtual machine mirror image is uploaded through the cloud platform, the web page reads the target virtual machine mirror image data, obtains the information flow corresponding to the target virtual machine mirror image according to the empty mirror image, shunts the information flow through the ingress load, and finally uploads the information flow to the UI server of the cloud platform through gateway authentication.
And (B) step (B): and uploading the information flow to an image module of the cloud platform after gateway authentication through a UI server of the cloud platform, so that the image module stores the attribute information and the metadata information of the target virtual machine image into a database.
Step C: after checking quota validity of the information flow through an image module of the cloud platform, uploading the information flow to a GLANCE module of the cloud operating system OPENSTACK so as to bypass load distribution and key authentication of the GLANCE module.
Step D: creating an empty mirror image file in the storage node according to the empty mirror image through the GLANCE module; and through the GLANCE module, the registration of the target virtual machine image in the database is completed by utilizing the attribute information and the metadata information of the target virtual machine image.
In this implementation manner, after receiving the information stream data, the enance module stores the empty image file in the rear end configured by the enance module, and registers the image information of the target virtual machine image in the database. That is, at this time, the GLANCE module creates an empty image file at the storage node and stores it in the ceph image pool configured by the GLANCE module.
In this way, the information stream data uploaded in the steps a-D are all empty files, so that no excessive time is spent.
S203: copying the target virtual machine image from the object storage to an empty image file of the storage node.
In this embodiment, after the target virtual machine image is uploaded to the object storage in step S201, and the empty image file is created in the storage node in step S202, further, the target virtual machine image may be copied from the object storage to the empty image file of the storage node.
Specifically, after uploading the target virtual machine image to the object storage and creating the empty image file in the storage node, further, the rbd client of the ceph cluster may be used to copy the target virtual machine image from the object storage to the empty image file in the ceph image pool configured by the glace module, that is, to use the target virtual machine image to cover the empty image file, so as to implement fast import of the target virtual machine image.
Further, after checking whether the state of the mirror image of the target virtual machine is normal, whether the mirror image service can be provided to the outside or not can be judged, namely, when the state of the mirror image of the target virtual machine is normal, the mirror image service can be provided to the outside.
In order to facilitate understanding of the method for fast importing a virtual machine image provided in the present application, next, the present application will introduce, with reference to fig. 3, an overall flow of the method for fast importing a virtual machine image based on object storage provided in the embodiment of the present application:
as shown in fig. 3, the method for fast importing a virtual machine image provided in the embodiment of the present application specifically includes: firstly, a virtual machine image to be uploaded is directly uploaded to an object storage through a storage network through an Amazon S3 interface, as shown in a step 0 marked in fig. 3, the transmission speed is high because the bandwidth of the storage network is relatively large and the process data flow is not subjected to other forwarding and shunting.
Then, uploading an empty mirror image through the cloud management platform, wherein the web page reads local mirror image data of a user, and the local mirror image data is shunted by an ingress load and finally uploaded to a UI server of the cloud management platform through gateway authentication, as shown in a step 1 marked in FIG. 3.
Next, the cloud management platform UI server uploads the data stream to the cloud management platform image module after gateway authentication, and the cloud management platform image module records the information such as the mirror image information and the metadata into the database, as shown in step 2 marked in fig. 3.
Further, the Image module performs verification such as quota validity on the mirror Image data, and then uploads the data to the spectrum module of the OPENSTACK. At this point, the ingress load splitting and key authentication by the OPENSTACK module are required, as shown in step 3 marked in FIG. 3.
Further, after receiving the data stream, the enance module of the OPENSTACK stores the image file in the rear end of the enance module configuration, and registers the image information in the database. At this point, the GLANCE module creates an empty image file at the storage node, and since the data stream uploaded in the steps is the empty file, it does not take too long, as shown in step 4 marked in FIG. 3. And finally, uploading the real mirror image to the object storage, finding the position of the previously uploaded empty file through the rbd client through the storage network, directly using the real mirror image to cover the empty file through copying, and checking whether the mirror image state is normal or not as shown in a step 5 marked in fig. 3, and providing mirror image service to the outside if the mirror image state is normal.
Therefore, after a reasonable mirror image uploading strategy is designed, the virtual machine mirror image can be rapidly and efficiently uploaded through the cloud platform.
In summary, according to the method for fast importing a virtual machine image provided in the present embodiment, a target virtual machine image is first determined, and uploaded to an object store, then an empty image corresponding to the target virtual machine image is uploaded through a cloud platform, an empty image file is created in a storage node according to the empty image, and attribute information and metadata information of the target virtual machine image are stored in a database, and then the target virtual machine image can be copied from the object store to the empty image file of the storage node. Therefore, the virtual machine image can be directly uploaded to the object storage through the storage network, when the cloud platform uploads the virtual machine image, the image data stream transmission link is reduced, the uploading time is shortened, meanwhile, the management network traffic is not occupied, the image uploading success rate is improved, the quick and efficient uploading of the virtual machine image is realized, and the user experience is improved.
