The processes may correspond to methods, functions, procedures, subroutines, and the like.
The existing container mirror image original data is directly stored in a disk, and operations such as storage, searching and deleting of the container mirror image are carried out in the disk. The current storage structure is only a disk, the storage structure is single, all data are stored in the disk, and when a user needs to search for needed data, much time is needed to search for the needed data from a plurality of data. And the original data which is not preprocessed is usually stored in the disk, so when the mirror image query is performed based on the current storage structure, a large amount of repeated computations are usually required, for example, computing the index ID of the mirror image layer, analyzing the mirror image metadata and performing hash check on the mirror image original data, and the container mirror image data corresponding to the ID can be queried after the verification is determined to pass. Therefore, the existing storage structure of the container mirror image cannot meet the requirements of users. According to the technical scheme of the embodiment of the invention, the storage structure of the container mirror image is set as the container mirror image metadata cache layer for storing the metadata of the container mirror image, and the container mirror image layer data cache layer for storing the data of the container mirror image layer, and the metadata of the container mirror image and the data of the container mirror image layer are obtained by preprocessing the original data of the container mirror image, so that the accuracy of different data storage positions can be ensured, and the subsequent extraction of the data from the storage structure is facilitated. The following will specifically describe by way of examples.
Example one
Fig. 1A is a schematic diagram of a storage structure of a container mirror according to an embodiment of the present invention, where as shown in the drawing, the storage structure of the container mirror includes a container mirror data cache layer and a container mirror data cache layer.
The container mirror image metadata cache layer is used for storing metadata of a container mirror image; the container mirror image layer data cache layer is used for storing the data of the container mirror image layer; the metadata of the container mirror and the data of the container mirror layer are obtained by preprocessing the original data of the container mirror.
When the storage structure of the container mirror image stores mirror image data, different cache layers are respectively adopted to store different mirror image data. The metadata of the container mirror image and the data of the container mirror image layer stored in different cache layers are respectively obtained by preprocessing the original data of the container mirror image, namely, a user can directly extract the mirror image data when acquiring the mirror image data from the cache layers without a complex check calculation process.
It should be noted that the preprocessing in this embodiment specifically includes operations such as parsing and checking, that is, parsing the container mirror image raw data, and extracting a first check value from the parsing result; directly carrying out Hash calculation on container mirror image original data to obtain a second check value; and performing calibration verification on the first check value and the second check value, taking an analysis result as container mirror image data after the verification is passed, and including metadata of the container mirror image and data of a container mirror image layer in the container mirror image data.
Specifically, the container mirror metadata in this embodiment includes: the system comprises a central processor architecture, container configuration information, container mirror identifiers, container instance configuration objects, creation time, versions, container mirror history information and an environment system. The container mirror layer data includes: mirror image layer identification, mirror image layer differential identification, mirror image layer parent identification, single-layer mirror image layer size and mirror image layer size sum. In addition, in order to facilitate subsequent deletion or search of data by a user, the container mirror image data is usually stored in a container mirror image data cache layer with a container mirror image identifier as an index, and the container mirror image layer data is stored in a container mirror image layer data cache layer with a container mirror image identifier as an index.
Optionally, the storage structure of the container image further includes a disk, and the disk is used for storing the container image original data.
Fig. 1B is a schematic diagram of another storage structure of a container mirror image provided in an embodiment of the present application, where the storage structure of the container mirror image includes: the system comprises a container mirror image data cache layer, a container mirror image layer data cache layer and a disk. In this embodiment, the metadata of the container mirror image and the container mirror image original data corresponding to the data of the container mirror image layer are stored in the disk, that is, the container mirror image original data needs to be backed up in the disk before the preprocessing. Therefore, when the program is interrupted or powered off, and data in the cache layer is lost, because the data in the disk is not lost under the power-off condition, when the program is restarted, the original data of the container mirror image can be read from the disk again, and the acquired metadata of the container mirror image and the data of the container mirror image layer are respectively restored in the corresponding cache layer through analysis and verification.
According to the technical scheme of the embodiment of the invention, the storage structure of the container mirror image is set as the container mirror image metadata cache layer for storing the metadata of the container mirror image, and the container mirror image layer data cache layer for storing the data of the container mirror image layer, and the metadata of the container mirror image and the data of the container mirror image layer are obtained by preprocessing the original data of the container mirror image, so that the accuracy of different data storage positions can be ensured, and the subsequent extraction of the data from the storage structure is facilitated.
Example two
Fig. 2A is a flowchart of a container mirror query method according to an embodiment of the present invention, where this embodiment may be implemented by a container mirror query device according to an embodiment of the present invention, and the device may be implemented in a software and/or hardware manner. As shown in fig. 2A, the method specifically includes:
and S101, importing the container mirror image data into a cache layer in advance for storage, wherein the cache layer comprises a container mirror image data cache layer and a container mirror image data cache layer.
Optionally, the importing container mirror data into the cache layer in advance for storage includes: preprocessing container mirror image original data to obtain container mirror image data, wherein the container mirror image data comprises metadata of a container mirror image and data of a container mirror image layer; and storing the metadata of the container mirror image in a container mirror image metadata cache layer by taking the container mirror image identifier as an index, and storing the container mirror image layer data in a container mirror image layer data cache layer by taking the container mirror image identifier as an index.
Specifically, in the embodiment, part of the container mirror image original data comes from the stored data of the disk, and part of the container mirror image original data comes from the external real-time input. In this embodiment, on one hand, a disk is initialized, specifically, a part of container mirror image raw data stored in the disk is preprocessed to obtain a first part of container mirror image data, and the preprocessed container mirror image data includes metadata of a container mirror image and data of a container mirror image layer. Wherein, the container mirror metadata include: the system comprises a central processing unit architecture, container configuration information, container mirror image identification, container instance configuration objects, creation time, versions, container mirror image historical information and an environment system; the container mirror layer data includes: mirror image layer identification, mirror image layer differential identification, mirror image layer parent identification, single-layer mirror image layer size and mirror image layer size sum. And storing the metadata of the container mirror image obtained by preprocessing in the disk in a container mirror image metadata cache layer by taking the container mirror image identifier as an index, and storing the container mirror image layer data in a container mirror image layer data cache layer by taking the container mirror image identifier as an index. On the other hand, when container mirror image raw data is imported from the outside, a part of the container mirror image data that is imported is also preprocessed, where, as shown in fig. 2B, the storage principle diagram of the container mirror image data is specifically a diagram for storing externally received container mirror image raw data, and a processing procedure for the externally received container mirror image raw data is substantially the same as a processing procedure for the container mirror image raw data read from the disk.
Optionally, preprocessing the container mirror image original data to obtain container mirror image data, including: analyzing the container mirror image original data to obtain an analysis result; extracting a first check value from the analysis result; directly carrying out Hash calculation on container mirror image original data to obtain a second check value; and comparing and checking the first check value and the second check value, and taking an analysis result as container mirror image data after the first check value and the second check value are confirmed to pass the checking.
Specifically, in this embodiment, regardless of whether container mirror image raw data read from a disk or received from the outside is stored in a cache layer after being preprocessed, since the container mirror image raw data is generally in a JSON format and cannot directly obtain specific parameter information of the container mirror image data, the container mirror image raw data needs to be parsed, metadata of a container mirror image included in the container mirror image data and data of a container mirror image layer are displayed in an object form, a first check code is extracted from the parsed metadata of the container mirror image, a second check code is obtained by directly performing hash calculation on the container mirror image raw data before parsing, an MD5 comparison check is performed on the directly extracted first check code and the calculated second check code, and if the two are the same, it is determined that the parsed container mirror image data is legal, the check is determined to be passed. And taking the analysis result as container mirror image data, storing the metadata of the container mirror image in the container mirror image data in a container mirror image data cache layer by taking the container mirror image identifier as an index, and storing the data of the container mirror image layer in a container mirror image layer data cache layer by taking the container mirror image identifier as an index.
It should be noted that the container mirror image metadata cache layer in this embodiment may include metadata of a plurality of container mirrors with different identifiers, where a specific amount is determined by the number of container mirror original data, and similarly, the container mirror image layer data cache layer may also include data of a plurality of container mirror layers with different identifiers, and the specific amount is not limited in this embodiment.
Optionally, the method further comprises: and directly storing container mirror image original data input from the outside in a disk.
Specifically, when the container mirror image original data input from the outside is received, the container mirror image original data input from the outside is directly stored in the disk so as to be stored in the database in the disk, so that when the program is interrupted or powered off and the data in the cache layer is lost, the data in the disk cannot be lost, and therefore when the program is restarted, the container mirror image original data can be read from the disk again, and the container mirror image data is obtained after analysis and verification and is stored in the cache layer.
Step S102, when the container mirror image data query instruction is determined to be received, directly obtaining container mirror image data from the cache layer according to the query instruction, wherein the query instruction comprises a container mirror image identifier.
Optionally, directly obtaining container mirror image data from the cache layer according to the query instruction includes: extracting the metadata of the container mirror image corresponding to the container mirror image identifier from the container mirror image metadata cache layer according to the query instruction; extracting data of the container mirror image layer corresponding to the container mirror image identifier from the data cache layer of the container mirror image layer according to the query instruction; and combining the metadata of the container mirror image corresponding to the container mirror image identifier with the data of the container mirror image layer to obtain the container mirror image data corresponding to the container mirror image identifier.
Specifically, as shown in fig. 2C, when it is determined that an inquiry instruction input by a user is received, metadata of a container mirror image corresponding to a container mirror image identifier is extracted from a container mirror image data cache layer according to the container mirror image identifier included in the inquiry instruction, and data of the container mirror image layer corresponding to the container mirror image identifier is also extracted from a container mirror image layer data cache layer according to the container mirror image identifier. For example, if it is determined that the query instruction includes a container mirror identifier ID001, the metadata of the container mirror with ID001 as an index is extracted from the container mirror metadata cache layer, and the data of the container mirror layer with ID001 as an index is extracted from the container mirror layer data cache layer. Because the metadata of the container mirror image and the data of the container mirror image layer are stored in the cache layer after being analyzed and checked, the metadata and the data can be directly extracted without the calculation process of a processor in the query process. And combining the metadata of the container mirror image with the ID001 as the index with the data of the container mirror image layer to obtain the container mirror image data corresponding to the ID001, and specifically returning the container mirror image data to the client for viewing in a calling mode of returning to the previous layer.
According to the technical scheme of the embodiment of the invention, the container mirror image data caching layer and the container mirror image layer data caching layer are added, the container mirror image data after being analyzed and verified is directly imported into the caching layer for storage, and is directly obtained from the caching layer according to the container mirror image identification when the query instruction is received, so that the repeated analysis and verification of the original container mirror image data in the query process are avoided, the load pressure of a processor is reduced, and the time delay of mirror image query is reduced.
EXAMPLE III

As shown in fig. 3A, the method includes:
step S201, a container mirror image deletion instruction is obtained, where the deletion instruction includes a container mirror image identifier.
Step S202, when the container mirror image deleting instruction is used, the metadata of the container mirror image stored in the container mirror image metadata cache layer is deleted.
Specifically, in this embodiment, after the container mirror image deletion instruction is acquired, the metadata of the container mirror image stored in the container mirror image metadata cache layer is deleted according to the container mirror image deletion instruction. As shown in fig. 3B, which is a schematic diagram illustrating a principle of deleting container mirror image data in the present embodiment, for example, when it is determined that a container mirror image delete instruction is received and a container mirror image identifier ID002 is included in the container mirror image delete instruction, metadata of a container mirror image in a container mirror image metadata cache layer indexed by ID002 is deleted according to the container mirror image delete instruction,
and step S203, deleting the data of the container mirror layer stored in the data cache layer of the container mirror layer according to the container mirror deleting instruction.
Specifically, in this embodiment, after the container mirror image deletion instruction is acquired, the data of the container mirror image layer stored in the data cache layer of the container mirror image layer is deleted according to the container mirror image deletion instruction. As shown in fig. 3B, for example, when it is determined that a container mirror deletion instruction is received and the container mirror identification ID002 is included in the container mirror deletion instruction, the container mirror layer data stored in the container mirror layer data cache layer indexed by the ID002 is deleted according to the container mirror deletion instruction.
Optionally, this embodiment further includes: and deleting the container mirror image original data stored in the disk according to the container mirror image deleting instruction.
It should be noted that, while the metadata of the container mirror and the data of the container mirror layer stored in the cache layer are deleted according to the container mirror deletion instruction, the original data of the container mirror identified as ID002 in the disk is also deleted. Therefore, when the user no longer needs to use the container mirror data, the storage pressure of the storage structure can be relieved by deleting the data.
According to the technical scheme of the embodiment of the invention, after the container mirror image deleting instruction containing the container mirror image identifier is obtained, the metadata of the container mirror image and the data of the container mirror image layer in different cache layers are deleted according to the container mirror image deleting instruction, so that the storage pressure of the storage structure is reduced by deleting the data.
