Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a cloud platform image management system according to an embodiment of the present disclosure. The system includes a management platform and a first type of storage pool and a second type of storage pool. The first type of storage pool and the second type of storage pool are relative terms. For example, the first type of storage pool is used to store a plurality of resource pools of one cluster, and the second type of storage pool is used to store resource pools corresponding to the plurality of clusters. The first type of storage pool is used for storing resource pools corresponding to a plurality of clusters respectively, and the second type of storage pool is used for storing a plurality of resource pools of one cluster. There may be more than one first-type storage pool, for example, fig. 1 is taken as an example including M first-type storage pools. Similarly, there may be more than one second-type storage pool, for example, fig. 1 includes K second-type storage pools as an example. The system shown in fig. 1 further includes N clusters, and as can be seen from fig. 1, 1 cluster corresponds to 1 first-type storage pool, and may correspond to a plurality of second-type storage pools.

It should be noted that a plurality of resource pools for storing a cluster may be considered as a pool for the cluster, which is also referred to as an object storage pool. The multiple resource pools for storing the multiple clusters may also be considered to be for the multiple clusters, i.e. the multiple clusters share the resource pool, also referred to as a block resource pool. The resources stored in the resource pool may be physical resources or virtual resources (or cloud resources). One cluster can correspond to one region, one region can be divided into a plurality of areas, and each area corresponds to one resource pool. Alternatively, one cluster may correspond to a plurality of resource pools.

A management platform may be used to manage the first type of storage pool and the second type of storage pool. In other words, the management platform may be used to schedule resources in the first type of storage pool as well as in the second type of storage pool. Wherein the management platform schedules the resource pool to be cluster-level. For example, taking a first cluster (first region) as an example, the management platform may provide mirror management services for all resource pools under the first cluster. It is to be appreciated that the image management service has access to a first type of storage pool and a second type of storage pool.

The following describes how the management platform provides the mirror management service for the resource pool under a certain cluster by using a specific example. In the following description, the cluster is taken as a first cluster, and the mirror providing the mirror management service is taken as a first mirror.

Example one, a private image is created.

Please refer to fig. 2, which is a flow chart illustrating the creation of the private image according to an embodiment of the present application. The flow shown in fig. 2 takes the example of importing a private image from a page.

S201, the management platform receives a second request instruction, and the second request instruction is used for storing the manufactured mirror image.

The user may import the created image into the object storage pool. For example, the user inputs a second request instruction to the management platform, which may include the first mirrored information and the path of the object storage pool. The management platform receives the second request instruction, and stores the mirror image indicated by the second request instruction in the corresponding object storage pool. The mirror indicated by the second request instruction is the first mirror as an example.

S202, the management platform receives a first request instruction, and the first request instruction is used for creating a first mirror image.

S203, the management platform copies the first mirror image file from the object storage pool to the block storage pool according to the type of the first mirror image.

When the private image needs to be created, the user can input a first request instruction to the management platform to request the management platform to create the first image. And after receiving the first request instruction, the management platform calls a copy interface of the object storage pool to copy the first mirrored file in the object storage pool to the block storage pool. Thereafter, the management platform invokes the mirror service to create (update) the mirror entry and update the local metadata information. As can be appreciated, the local metadata information is used to indicate the resource pool in which the chunk storage pool is stored. Creating a mirrored entry may be considered as adding the entry of the first mirror to the original mirrored entry. The copy interface of the object storage pool in the embodiment of the present application is not limited, and for example, the interface may be an S3 interface or a swift copy interface of the object storage pool.

In this example, the private images are uniformly stored in the object storage pool, and any private image in the object storage pool can be shared, so that the resource requirement can be met as much as possible. In addition, the storage space for storing the private image can be saved.

And S204, the management platform receives a deleting instruction, and the deleting instruction is used for deleting the second mirror image.

S205, the management platform deletes the second mirror image after determining that no virtual system disk is created based on the second mirror image.

It will be appreciated that the created image is not required by the user, for example the second image, which may be transmitted in order to save storage space. Specifically, the user may input a delete command to the management platform, where the delete command may carry information of the second image. And the management platform receives the deletion instruction, firstly judges that all resource pools corresponding to the current cluster have no virtual system disk and is created based on the second mirror image, and then deletes the second mirror image. I.e., the second image is deleted from the object storage pool or the chunk storage pool. On the contrary, if all resource pools corresponding to the current cluster further have a virtual system disk created based on the second image, the management platform may output a prompt message to prompt a reason why the second image cannot be deleted.

Example two, a private image is created. The difference from example one is that example two exemplifies the creation of a private image from a virtual system disk.

Please refer to fig. 3, which is another schematic flow chart illustrating the creation of the private image according to an embodiment of the present application. The flow shown in FIG. 3 exemplifies the creation of a private image from a virtual system disk.

S301, the management platform receives a second request instruction, and the second request instruction is used for storing the manufactured mirror image.

The user may import a manufactured image, such as the first image, into the chunk store pool. For example, the user inputs a second request instruction to the management platform, which may include the first mirrored information and the path of the chunk storage pool. The management platform thus receives the second request instruction to store the first image in the corresponding block storage pool.

S302, the management platform receives a first request instruction, and the first request instruction is used for creating a first mirror image.

S303, the management platform copies the file of the first mirror image from the block storage pool to the system disk according to the type of the first mirror image.

The difference from S202 is that after receiving the first request instruction, the management platform calls an upload system disk interface of the block storage pool to copy the first mirrored file in the block storage pool to the system disk. And copy the data of the system disk to the block storage pool. Thereafter, the management platform invokes the mirror service to create a mirror entry and update the local metadata information. It will be appreciated that the local metadata information is used to indicate the resource pool in which the chunk storage pool is stored. Creating a mirrored entry may be considered as adding the entry of the first mirror to the original mirrored entry.

It should be noted that, in the second example, the flow of the second image may also be deleted by itself, which is specifically referred to the description in the first example and is not described herein again.

Example three, a public mirror is created. The public image refers to a common template that all users can use, including but not limited to images of operating systems such as ubuntu, windows, centros, etc.

Please refer to fig. 4, which is a flowchart illustrating creation of a public mirror image according to an embodiment of the present application.

S401, the management platform receives a second request instruction, and the second request instruction is used for storing the manufactured mirror image.

The user may import the composed first image into the chunk store pool. For example, the user inputs a second request instruction to the management platform, which may include the first mirrored information and the path of the chunk storage pool. The management platform thus receives the second request to store the first image in a corresponding block storage pool, such as the first block storage pool. The first block storage pool may be any one of the block storage pools.

S402, the management platform synchronizes the first mirrored file in the first block storage pool to other block storage pools.

When the management platform stores the first image in the first block storage pool, a synchronization operation may be performed to synchronize the first image to the other block storage pools. Thereby realizing the creation of public mirror images.

In this example, the public mirror image is stored in any storage pool, and the virtual system disk can be cloned more quickly.

Example four, a system disk is created for mirroring. It is understood that there are private images and public images. How to create the system disk is described below for private and public images, respectively.

With respect to public images, it should be understood that public images are stored in each block storage pool. The performance of different fast storage pools may also vary. For example, a block storage pool with faster read and write speeds may be considered a high performance storage pool. In contrast, the block storage pools having slower read and write speeds may be considered normal storage pools and high performance storage pools. When creating a system disk for a public image, a snapshot may be taken from a first block storage pool storing a first image, from which a system disk may be cloned. Alternatively, the first image may be copied from the first block storage pool to the high performance storage pool, a snapshot may be made from the high performance storage pool, and a system disk may be cloned from the snapshot. According to the embodiment of the application, the public mirror image is stored in any storage pool, so that the virtual system disk can be cloned more quickly.

For private mirroring, the management platform may invoke the mirroring service to download the files of the first image from the object storage pool to a local temporary directory of the node where the block storage service is located. Thereafter, the management platform may invoke an import command of the block store to import the first mirrored file into the pool of block storage volumes. It is understood that if the mirror format is not raw, the management platform performs a mirror format conversion operation before importing, e.g. the management platform may perform the mirror format conversion operation through the conversion tool qemu-img. In the embodiment of the application, the private image can be shared in a plurality of storage pools, and a user can create the virtual machine resource in any storage pool by using the private image, namely the virtual machine resource is constructed more quickly.

It should be noted that, the foregoing examples one to four may be combined with each other, and the embodiments of the present application are not limited thereto. As can be seen from the foregoing examples one to four, the cloud platform image management system provided in the embodiment of the present application supports unified management of images of multiple storage pools in the same cluster. For example, the private images are uniformly stored in the object storage pool, and any private image in the object storage pool can be shared, so that the resource requirement can be met as much as possible. In addition, the storage space for storing the private image can be saved. And the private mirror image can be shared in a plurality of storage pools, and a user can use the private mirror image to create the virtual machine resource in any storage pool, namely the virtual machine resource is constructed more quickly. For another example, the public mirror image is stored in an arbitrary block storage pool, and the virtual system disk can be cloned more quickly.
