Description
Technical Field
The present application relates to the field of internet technologies, and in particular, to a method, an apparatus, and a server for creating and acquiring an image file.
Background
The cloud PaaS (Platform as a Service ) platform is an operation supporting platform established based on a cloud computing technology, and third-party software developers can deploy application products on the cloud PaaS platform and provide services for users. The traditional cloud PaaS platform generally adopts a virtual machine to realize the isolation of different software developer applications, and takes the virtual machine as a minimum unit of scheduling, but when the virtual machine is adopted as the minimum unit, a plurality of problems such as long starting time, more occupied system resources, time consumption of migration adjustment and the like exist. Based on the method, the novel cloud PaaS platform can adopt a container technology to realize the isolation of different software developer applications, and the container is used as the minimum unit of scheduling. The container technology is a virtualization technology, and an application is managed by means of a virtualized operating system, and each container contains an exclusive complete user environment space.
Because of the large number of users, a large number of containers may be deployed at a server in order to provide services to the users, which together provide services to the users, thereby avoiding overloading a container. Moreover, these containers can obtain the same image file and run the image file to provide services to the user.
Currently, a server generates an image file locally, stores the image file in a storage server, and each container obtains the image file from the storage server and stores the image file locally. In general, the image file is relatively large, such as 3G, so that a large amount of disk space is required when the image file is locally generated; the server occupies a lot of bandwidth and takes a long time when storing the image file to the storage server. When each container acquires an image file from a storage server, a large amount of bandwidth is occupied, and long time is consumed; each container requires a lot of disk space when storing the image file locally.

Moreover, in other embodiments, the steps of the corresponding methods need not be performed in the order shown and described herein, and the methods may include more or less steps than described herein. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; various steps described in this specification, in other embodiments, may be combined into a single step.
Based on the above technical scheme, in the embodiment of the present application, when the second server obtains the image file, the third disk in the storage device is mounted to the second server, and the image file in the third disk is operated. In this way, the second server may utilize the disk space of the storage device without taking up a significant amount of the disk space of the second server. The second server only needs to acquire the description information of the first disk, and does not need to acquire the image file from the storage server, and the size of the description information is far smaller than that of the image file, so that the problems of occupation of a large amount of bandwidth, long time consumption and the like are solved. Based on the mode, the image file distribution efficiency can be improved, the image file distribution is quickened, the time expenditure is saved, and the local storage resources of the server can be saved.
The following describes the above technical solution in detail with reference to a specific application scenario, and is shown in fig. 3A, which is a schematic diagram of an application scenario in an embodiment of the present application. The first server may be referred to as a package server for building an image file of the application; the storage device may be a distributed block device, also referred to as a block device cluster, and may provide functions of creating a disk, snapshot the disk, cloning the disk from the snapshot, and so on; the storage server can be a mirror image warehouse or a database, and is used for storing the corresponding relation between mirror image information of a mirror image file and description information of a disk, and also providing functions of authentication service, unified file storage service and the like; the second server may be an operating environment of the container, and the disk of the storage device may be mounted to the second server for use by the container.
In one example, a distributed block device may include a large number of memory blocks (e.g., fixed size memory blocks) that may be provided to a server such that the server may create a disk from the memory blocks provided by the distributed block device, where the disk may be composed of a plurality of memory blocks, e.g., a disk size of 100M and a memory block size of 4M, where the disk may be composed of 25 memory blocks. The processing of the disk by the server is actually the processing for the 25 memory blocks, i.e. the data is stored in the memory blocks of the distributed block device.
The magnetic Disk in this embodiment may be a type of magnetic Disk such as SSD (Solid State Drive ), HHD (Hybrid Hard Drive, hybrid Hard Disk Drive), HDD (Hard Disk Drive), or the like, or may be a type of phase change memory magnetic Disk, a type of quantum memory magnetic Disk, a type of graphene memory magnetic Disk, or the like, and the type of the magnetic Disk is not limited as long as it is used for storing data.
Wherein a container for running the image file can be deployed at the second server and services can be provided to the user by running the image file. Moreover, for some application (e.g., a commodity center application), a large number of containers may be deployed for providing services to users, and these containers may be deployed on multiple second servers. For example, the container 1-container 10 is disposed at the second server 1, the container 11 is disposed at the second server 2, the container 12-container 18 is disposed at the second server 3, and so on, the manner of disposition is not limited.
In the conventional manner, the first server writes the image file in the local disk, so that a large amount of disk space is occupied; in the embodiment of the application, the first server applies for a disk from the storage device and mounts the disk locally, so that the image file is directly written into the storage device, thereby saving disk space.
In the traditional mode, the first server stores the image file to the storage server, so that a large amount of bandwidth is occupied, and a long time is consumed; in the embodiment of the application, the first server stores the description information of the disk to the storage server, and the size (such as 1K) of the description information is far smaller than the size (such as 3G) of the mirror image file, so that the data storage speed is increased, and the problems of occupying a large amount of bandwidth, consuming a long time and the like are solved.
In the traditional mode, the second server needs to acquire the image file from the storage server, occupies a large amount of bandwidth and needs to consume a long time; in the embodiment of the application, the second server only needs to acquire the description information of the disk from the storage server, and the size (such as 1K) of the description information is far smaller than the size (such as 3G) of the mirror image file, so that the data reading speed is increased, and the problems of occupation of a large amount of bandwidth, long time consumption and the like are solved.
In the traditional mode, the second server needs to store the image file locally, so that a large amount of disk space is occupied; in the embodiment of the application, the second server can mount the disk of the storage device to the second server, and the container runs the image files in the disk, for example, the mount directory of the disk is used as the container root directory, and then the container is started, so that the container runs the image files in the disk, and the local disk space is saved.
Referring to fig. 3B, a flowchart of a method for obtaining an image file is shown, which may include:
in step 301, a first server obtains an image file a, and determines a disk size occupied by the image file a.
For example, the first server may receive an image file a input by the developer, where the image file a may include a disk size occupied by the image file a (hereinafter, a disk size 1 is illustrated as an example, and the disk size 1 may be 3G, for example). Of course, image file a may also include other content, without limitation.
In step 302, a first server sends a create message to a storage device carrying a disk size of 1.
In step 303, after receiving the creation message, the storage device creates a first disk corresponding to the disk size 1 locally, and subsequently refers to the first disk as disk a, where the size of disk a is disk size 1.
In step 304, the first server mounts the disk a to the first server. For example, the first server creates a directory for image file a and mounts the disk a under the directory of the first server.
The mounting of the disk a to the first server means that the disk a of the remote storage device is directly used by being mounted to the first server, and the operation on the disk a is the operation directly to the remote storage device.
In step 305, the first server writes image file a to disk a. For example, when the first server writes the image file a to the directory, the image file a is actually written to the disk a.
Wherein the process of the first server writing the image file a to the disk a is actually writing the image file a directly to the disk a of the storage device, instead of writing to the disk local to the first server.
In step 306, the first server converts disk a in the storage device to snapshot a.
After the first server writes the image file a into the disk a, if the image file a is written, the complete image file a is written into the disk a of the storage device. Considering that the disk a is a readable/writable disk, in order to avoid modifying the image file a in the disk a, the disk a may be converted into a snapshot a (for example, the first server sends a conversion command for the disk a to the storage device, and the storage device converts the disk a into the snapshot a, which is not limited in this conversion process), where the content of the snapshot a is the same as that of the disk a, that is, the snapshot a also includes the complete image file a. Moreover, snapshot a is a readable and non-writable snapshot, i.e., modification of image file a in snapshot a is not possible. Furthermore, the same disk as disk A may also be cloned using this snapshot A, and the subsequent examples describe the cloning process.
In step 307, the first server determines description information of disk a, where the description information may include, but is not limited to, description information of a corresponding snapshot (e.g., snapshot a) of disk a in the storage device.
For example, after the storage device converts the disk a into the snapshot a, description information of the snapshot a (such as a name, creation time, and the like of the snapshot a, which are not limited thereto) may be sent to the first server, and the first server may receive the description information of the snapshot a, that is, the description information of the disk a.
In step 308, the first server stores the corresponding relationship between the description information of the disk a and the image information (such as the image name, the image parameter, etc., without limitation) of the image file a in the storage server.
The first server may obtain the image information from the image file a, and send the description information of the disk a and the image information to the storage server, so that the storage server stores the correspondence between the description information of the disk a and the image information.
In step 309, the first server sends the image information of the image file a to the second server.
Of course, the image information of the image file a may be sent to the second server in other manners, for example, the developer sends the image information of the image file a to the second server, which is not limited thereto.
In step 310, the second server obtains the image information corresponding to the image file a.
In step 311, the second server queries the description information corresponding to the mirror information from the storage server. The storage server stores the correspondence between the image information of the image file a and the description information of the disk a, so that after the second server obtains the image information of the image file a, the second server can query the description information corresponding to the image information, that is, the description information of the disk a, from the storage server.
In step 312, the second server sends a clone message carrying the description information of disk A to the storage device.
In step 313, after receiving the cloning message, the storage device queries the snapshot a corresponding to the description information (such as the name and creation time of the snapshot a) of the disk a, and clones the snapshot a (the cloning process of the snapshot a is equivalent to cloning the disk a), to obtain the cloned disk B.
Wherein, since snapshot a includes image file a, disk B also includes image file a.
In step 314, the second server mounts disk B to the second server. For example, the second server may create a mount directory for disk B and mount disk B under the mount directory of the second server.
In step 315, the second server runs image file a on disk B. For example, the mount directory may be used as a container root directory, and then the container is started, so that the container runs the image file a in the disk B.
Wherein the second server runs the image file a in disk B, instead of using a disk local to the second server, in effect directly running the image file a in disk B of the storage device.
The second server where each container is located may use steps 310 to 315, so as to run the image file a in the disk of the storage device, and then provide the service corresponding to the image file a to the user.
Referring to fig. 3C, another flowchart of a method for obtaining an image file may include:
in step 321, the first server obtains the image file B, determines the disk size occupied by the image file B, and determines the image information of the image file associated with the image file B. For example, when image file A is associated with image file B, then the image information may include image information for image file A.
Wherein, the association of the image file A and the image file B means that: in order to realize the function of the image file B, the function needs to be realized on the basis of the image file a, that is, the image file B can multiplex the content of the image file a.
For example, the first server may receive an image file B input by the developer, which may include image information of an image file a associated with the image file B. In addition, the image file B may include a disk size occupied by the image file B (hereinafter, the disk size 2 will be described as an example, for example, the disk size 2 may be 4G). Of course, image file B may also include other content, without limitation.
In step 322, the first server queries the storage server for description information corresponding to the image information. The mapping information of the image file a and the description information of the disk a are stored in the storage server, so that the first server may query the description information corresponding to the mapping information, that is, the description information of the disk a, from the storage server after obtaining the mapping information of the image file a.
In step 323, the first server sends a create message to the storage device, where the create message may carry the disk size 2 and description information of the disk a (e.g., description information of the snapshot a corresponding to the disk a).
In step 324, after receiving the creation message, the storage device creates a disk C corresponding to the disk size 2 locally, that is, the size of the disk C is the disk size 2. When the storage device creates the disk C, firstly, the snapshot a corresponding to the description information (such as the name and the creation time of the snapshot a) of the disk a is queried, and the snapshot a is cloned (the cloning process of the snapshot a is equivalent to that of the disk a), so as to obtain a cloned disk D, and then, the storage device creates the disk C on the basis of the disk D, that is, the disk D may include the image file a in the snapshot a, and the disk C includes the image file a.
In step 325, the first server mounts disk C to the first server. For example, the first server creates a directory for image file B and mounts the disk C under the directory of the first server.
At step 326, the first server writes image file B to disk C. For example, when the first server writes the image file B to the directory, the image file B is actually written to the disk C.
Wherein the process of the first server writing the image file B to the disk C is actually writing the image file B directly to the disk C of the storage device, instead of writing to the disk local to the first server. Also, after image file B is written to disk C, disk C may include image file a and image file B.
In step 327, the first server converts disk C in the storage device to snapshot C.
After the first server writes the image file B into the disk C, if the writing of the image file B is completed, the image file a and the image file B are written into the disk C of the storage device. Considering that the disk C is a readable/writable disk, in order to avoid modification of the image file a and the image file B in the disk C, the disk C may be converted into a snapshot C, where the content of the snapshot C is the same as that of the disk C, i.e. the snapshot C may also include the image file a and the image file B. Moreover, snapshot C is a readable and non-writable snapshot, i.e., modification cannot be performed on image file a and image file B in snapshot C. Furthermore, the same disk as disk C may also be cloned using this snapshot C, and the subsequent examples describe the cloning process.
In step 328, the first server determines description information for disk C, where the description information may include, but is not limited to, description information for a corresponding snapshot (e.g., snapshot C) of disk C in the storage device.
For example, after the storage device converts the disk C into the snapshot C, description information of the snapshot C (such as a name, creation time, etc. of the snapshot C, without limitation, may be sent to the first server, and the first server may receive the description information of the snapshot C, that is, the description information of the disk C.
In step 329, the first server stores the correspondence between the description information of the disk C and the image information (such as the image name, the image parameter, etc., without limitation) of the image file B in the storage server.
The image file B may further include image information of the image file B, and the first server may obtain the image information from the image file B, and send the description information of the disk C and the image information to the storage server, so that the storage server stores a correspondence between the description information of the disk C and the image information.
In step 330, the first server sends the image information of the image file B to the second server.
Of course, the image information of the image file B may be sent to the second server in other manners, for example, the developer sends the image information of the image file B to the second server, which is not limited thereto.
In step 331, the second server obtains the image information corresponding to the image file B.
In step 332, the second server queries the description information corresponding to the mirror information from the storage server. The mapping relation between the mirror information of the mirror file B and the description information of the disk C is stored in the storage server, so that after the second server obtains the mirror information of the mirror file B, the description information corresponding to the mirror information, that is, the description information of the disk C, can be queried from the storage server.
In step 333, the second server sends a clone message to the storage device carrying the description information of disk C.
In step 334, after receiving the cloning message, the storage device queries the snapshot C corresponding to the description information (such as the name and creation time of the snapshot C) of the disk C, and clones the snapshot C (the process of cloning the snapshot C is equivalent to cloning the disk C), to obtain the cloned disk E. Since snapshot C includes image file a and image file B, disk E also includes image file a and image file B.
In step 335, the second server mounts disk E to the second server. For example, the second server may create a mount directory for disk E and mount the disk E under the mount directory of the second server.
In step 336, the second server runs image file A and image file B on disk E. For example, the mount directory may be used as a container root directory, and then the container is started, so that the container runs the image file a and the image file B in the disk E, and a service corresponding to the image file B may be provided to the user.
Based on the above technical scheme, in the embodiment of the present application, when the first server generates the image file, the first server creates the first disk corresponding to the image file in the storage device, mounts the first disk to the first server, and writes the image file to the first disk. In this way, the first server may utilize the disk space of the storage device without taking up a significant amount of the disk space of the first server. Moreover, the first server provides the description information of the first disk to the second server instead of storing the image file in the storage server, and the size of the description information is far smaller than that of the image file, so that the problems of occupying a large amount of bandwidth, consuming a long time and the like are solved. When the second server (such as a container of the second server) acquires the image file, a third disk in the storage device is mounted on the second server, and the image file in the third disk is operated. In this way, the second server may utilize the disk space of the storage device without taking up a significant amount of the disk space of the second server. The second server only needs to acquire the description information of the first disk, and does not need to acquire the image file from the storage server, and the size of the description information is far smaller than that of the image file, so that the problems of occupation of a large amount of bandwidth, long time consumption and the like are solved. Obviously, based on the mode, the image file distribution efficiency can be improved, the image file distribution is quickened, the time expenditure is saved, and the local storage resources of the server are saved.
In the above embodiment, in order to protect the storage device, the concurrency of the storage device may also be controlled. For example, applying for the storage device that the number of containers of the disk does not exceed a preset threshold (e.g., 2000); or, determining whether to accept the application flow of the new container by detecting the flow of the storage device in real time, if the flow of the storage device is not greater than the threshold value, allowing the new container to apply for the disk, and if the flow of the storage device is greater than the threshold value, not allowing the new container to apply for the disk. Of course, the above manner is merely an example, and is not limited thereto.
