Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The container preservation method provided by the application can be applied to the computer equipment shown in figure 1. The computer device may be a terminal, and its internal structure may be as shown in fig. 1. The computer device includes a processor, a memory, a network interface, a display screen, and an input device connected by a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage media. The network interface of the computer device is used for communicating with an external terminal through a network connection. The computer program is executed by a processor to implement a container saving method. The display screen of the computer equipment can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer equipment can be a touch layer covered on the display screen, can also be keys, a track ball or a touch pad arranged on the shell of the computer equipment, and can also be an external keyboard, a touch pad or a mouse and the like.
It will be appreciated by those skilled in the art that the architecture shown in fig. 1 is merely a block diagram of some of the architecture relevant to the present inventive arrangements and is not limiting as to the computer device to which the present inventive arrangements may be implemented, as a particular computer device may include more or less components than those shown, or may be combined with some components, or may have a different arrangement of components.
The current method for perfectly storing the modified content of the container is completed through the container operation instruction provided by the authorities, and particularly in the storing process, the modified content of all the readable and writable layers after the container is built is used as a new mirror image layer, so that the container is stored to a new mirror image. However, the container preservation method described above has the following drawbacks: first, there are many cloud mirror image storage servers in the industry at present that limit the single-layer mirror image space, so that the above container storage method cannot flexibly store according to the single-layer mirror image space limit. When the modified file size in the readable and writable layer of the container exceeds the single-layer mirror image space limit, the obtained mirror image cannot be directly uploaded to the cloud mirror image warehouse even if the modified container is stored. Such a mirror image that can only be used locally does not exert its value in the industrial field. Meanwhile, in most of the existing cloud mirror warehouse services, pushing is repeatedly attempted when the mirror exceeding the size limit is pushed to a cloud server, which is quite troublesome for building the mirror uploading service which is increasingly automated in the industry. Therefore, due to the limitation of the cloud mirror warehouse and the size requirement of the mirror structure when the user stores the container, a feasible scheme is needed to meet the different requirements of the single-layer mirror size when the container is stored, and the application provides a container storage method for solving the technical problems.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail by examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a flowchart of a method for storing a container, where the method is implemented by the computer device in fig. 1, and the method relates to a specific process of storing a modified container by the computer device. As shown in fig. 2, the method specifically includes:
s101, acquiring target modification content of a target container; the target modification content includes modification content of a read-write layer in the target container.
The container is a standard software unit containing file resources, system resources and development environment dependence, and each container can directly use the CPU, the memory and the hard disk on the physical machine where the container is located, and the performance of the container is close to that of the physical machine. The target container is a container that has been modified and needs to be saved.
In this embodiment, the computer device may create a container based on a preset mirror image, and then modify the container, so as to obtain the target container. Further, when the computer device needs to store the modified container, that is, the target container, the computer device may directly extract the target modified content from the readable and writable layer of the target container through the container operation instruction issued by the authority, optionally, the computer device may also extract the modified content of all layers from the target container through the container operation instruction issued by the authority, and further extract the target modified content in the readable and writable layer therefrom, so as to execute the operation of storing the target container according to the target modified content in the readable and writable layer. Each row of modified content in the readable and writable layer, namely, the extracted target modified content comprises a file modification operation and a file modification object, and the file modification object comprises a file directory and a specific file. File modification operations may be categorized as C (modification), D (deletion), a (addition). The target modification content may be presented in any form, e.g., list, collection, member, etc. For another example, the target modification content may be represented in table 1 below:
TABLE 1
| A/root/config |
| C/root/.cache |
| D/urs/local/lib/python3.0/dist-packages/grpcio-1.21.1.dist-info |
S102, dividing target modified content to obtain a plurality of partition modified content lists, so that the size of a storage space occupied by modified content contained in each partition modified content list is smaller than a preset threshold; the preset threshold is determined according to the size of the single-layer mirror image storage space of the cloud mirror image warehouse.
The cloud mirror image warehouse is a place for storing mirror image files in a centralized mode, a plurality of cloud mirror image warehouses are often stored on a cloud warehouse server, and different cloud mirror image warehouses often have different limits on the size of a storage single-layer mirror image. In practical application, the preset threshold is a storage limit value of the cloud mirror warehouse on a single-layer mirror image when the cloud mirror warehouse mirrors the storage container, and different cloud mirror warehouses correspond to different preset thresholds.
In this embodiment, when the computer device obtains the target modified content of the target container, the target modified content may be further divided, and specifically, the computer device may divide a plurality of rows of modified content included in the target modified content into groups, or partition the modified content into partitions, and the sizes of the modified content included in each group or each partition may be the same or different, but are smaller than the preset threshold. After the computer device divides the target modified content, the divided modified contents of multiple groups or multiple partitions may be written into a preset table, so as to obtain multiple partition modified content lists each containing multiple lines of modified content, and finally the above dividing operation makes the size of the storage space occupied by the modified content contained in each partition modified content list smaller than a preset threshold.
S103, modifying and storing the current target container according to the multiple partition modification content lists in sequence to obtain a corresponding target mirror image; the current target container is created from the original image to which the target container corresponds.
Wherein the current target container is an unmodified container that can be created based on the original image by the container operation instructions used to create the container. In this embodiment, the computer device may first create a current target container based on the original image corresponding to the target container, when the computer device obtains the multiple partition modified content lists, may first select one partition modified content list from the multiple partition modified content lists, modify and store the current target container according to the modified content in the modified content list, then select one partition modified content list from the multiple partition modified content list, modify and store the last stored container according to the modified content in the modified content list, and perform the cyclic operation in this manner until the multiple partition modified content lists are traversed, and finally obtain the modified and stored container, that is, the target image, where the size of each layer of image in the target image is smaller than the preset threshold.
The container preservation method provided in this embodiment includes: obtaining target modification content of a target container, dividing the target modification content to obtain a plurality of partition modification content lists, and modifying and storing the current target container according to the partition modification content lists in sequence to obtain a corresponding target mirror image. In the method, the size of the storage space occupied by the modified content in each divided partition modified content list is smaller than the preset threshold, so that the size of the single-layer image in the target image obtained according to the modified content in each divided partition modified content list is also smaller than the preset threshold, and in practical application, the target image can be directly uploaded to any cloud image warehouse because the preset threshold is a limit value of the cloud image warehouse to the storage size of the single-layer image, and the size of the single-layer image in the target image cannot exceed the limit of the cloud image warehouse due to excessive modified content of a container, so that the single-layer image cannot be normally uploaded to the cloud image warehouse. Therefore, the container preservation method provided by the application not only can be suitable for local application, but also can be suitable for network application in various fields, and has strong popularization and application.
Optionally, the present application further provides a specific embodiment of S102, as shown in fig. 3, where S102 "divides the target modified content to obtain a plurality of partition modified content lists", and includes: and executing a dividing operation on each row of modified content in the target modified content to obtain a plurality of partition modified content lists. As shown in fig. 3, for the modified content of the current line, the corresponding dividing operation includes the following steps:
s201, reading the modification content of the current line in the target modification content.
In particular, when dividing according to the target modified contents, the computer device may read the modified contents of each line in the target modified contents line by line in units of lines so as to perform different dividing operations on the modified contents of each line later.
S202, dividing the modification content of the current line into a corresponding partition modification content list according to the type of the modification content of the current line and the operation type of the modification content of the current line.
Wherein the types of modified content include files and folders; the operation types of modifying the content include modification, deletion, addition, and the like. In this embodiment, when the computer device obtains the target modified content, the modified content of each line may be read line by line, and according to the type of the modified content of each line and the operation type of the modified content, a corresponding dividing operation is performed on the modified content of each line, and the modified content of each line is divided into corresponding partition modified content lists, so as to finally obtain a plurality of partition modified content lists.
The following embodiment describes a specific implementation of the dividing operation by taking the modification content of the current line as a reading, that is, the specific implementation of S202 described above, as shown in fig. 4, including:
s301, if the type of the modified content of the current row is a folder and the operation type of the modified content of the current row is adding or deleting, adding the modified content of the current row into a first partition modified content list.
The first partition modified content list is a blank one-dimensional list prepared by the computer equipment in advance and is used for storing modified content of the current row read by the computer equipment, the initial value of the modified content is zero, and the size of the modified content increases with the addition of the modified content. In practical application, since the folder does not occupy any space, according to the characteristic, the computer device may directly add the modified content to the first partition modified content list when the type of the modified content in the current row is the folder and the operation type of the modified content is addition; accordingly, the operation of deleting the folder does not increase the size of the readable and writable mirror layer, and thus, according to this feature, the computer device can directly add the modified content to the first partition modified content list when the type of the modified content of the current line is the folder and the operation type of the modified content is the deletion.
S302, if the type of the modified content of the current line is a file and the operation type of the modified content of the current line is deletion, adding the modified content of the current line into a first partition modified content list.
The above operation of deleting a file does not increase the size of the readable and writable mirror layer, and thus, according to this feature, the computer device can directly add the modified content to the first partition modified content list when the type of the modified content of the current line is a file and the operation type of the modified content is deletion.
S303, if the type of the modified content of the current line is a file and the operation type of the modified content of the current line is addition or modification, judging whether the sum of the size of the modified content of the current line and the size of the first partition modified content list is greater than a preset threshold value, and dividing the modified content of the current line into corresponding partition modified content lists according to a judging result.
The above-mentioned operation of adding or modifying a file may directly affect the size of the readable and writable mirror layer, especially if the added file is larger or the modified file is larger, so, based on this feature, the computer device may further determine whether the sum of the size of the modified content of the current line and the size of the first partition modified content list is greater than a preset threshold when the type of the modified content of the current line is a file and the operation type of the modified content is addition or modification, and then divide the modified content of the current line into corresponding partition modified content lists according to the determination result, so that the size of each partition modified content list is smaller than the preset threshold, even if the size of each partition modified content list is within the storage limit range of the mirror cloud repository for the single-layer mirror layer.
Specifically, in S303, the "dividing the modification content of the current line into the corresponding partition modification content list according to the determination result" includes, as shown in fig. 5:
s401, if the judgment result is that the sum of the size of the modified content of the current line and the size of the first partition modified content list is larger than a preset threshold value, adding all the content in the first partition modified content list to the second partition modified content list, adding the modified content of the current line to the emptied first partition modified content list, and setting the size of the first partition modified content list after the content is added as the size of the modified content of the current line.
The second partition modified content list is a blank two-dimensional list prepared by the computer equipment in advance and is used for storing modified contents of a plurality of rows, which are removed from the first partition modified content list by the computer equipment, of which the initial value is zero and the size is changed with the increase of added modified contents.
The present embodiment relates to an application scenario in which the result of the determination is that the sum of the size of the modified content of the current line and the size of the first partition modified content list is greater than a preset threshold, where the scenario indicates that the size of the modified content of the added lines in the first partition modified content list is smaller than the preset threshold, but if the modified content of the current line is added again, the modified content of the added lines in the first partition modified content list exceeds the preset threshold, which is equivalent to exceeding the storage limit of the cloud mirror warehouse on the single-layer mirror, so that in the application scenario, the computer device may add all the modified content in the first partition modified content list to the second partition modified content list at this time to obtain a partition modified content list, and then the size of the partition modified content list is smaller than the preset threshold. Then, the computer device empties the first partition modified content list, adds the modified content of the current line to the emptied first partition modified content list, then sets the size of the first partition modified content list to the size of the modified content of the current line, so as to update the size of the first partition modified content list in time, and then accurately obtains the judgment result.
And S402, if the judgment result is that the sum of the size of the modified content of the current line and the size of the first partition modified content list is smaller than or equal to a preset threshold value, adding the modified content of the current line into the first partition modified content list.

Fig. 7 is a flowchart of one implementation of S103 in the embodiment of fig. 2, where the embodiment relates to a specific process of modifying and saving a current target container by a computer device based on a plurality of partition modified content lists, and as shown in fig. 7, S103 "modifying and saving the current target container according to the plurality of partition modified content lists in turn, and obtaining a corresponding target image" includes:
s501, sequentially traversing a plurality of partitions to modify the content list.
And the container storing operation currently executed is based on a new container and a corresponding new mirror image obtained after the container is modified in the previous time, which is equivalent to adopting an iterative method to realize the storage of the target container.
S502, modifying and storing the current target container according to the current traversed partition modification content list to obtain the current mirror image.
The current target container is a container which needs to be modified currently, and the current target container can be a container which is obtained after the original image corresponding to the target container is created, or can be a container which is obtained after the image corresponding to the container after each modification is created. The current mirror image is the mirror image which needs to be modified currently, and can be the mirror image obtained after the current target container is modified and stored for the first time, or the mirror image obtained after the container modified each time is modified and stored again. The current traversed partition modified content list is a modified content list that needs to be referenced each time a container needs to be modified. In this embodiment, when the computer device obtains the partition modification content list currently traversed, the corresponding current target container to be modified may be modified according to the modification content of each line in the partition modification content list through the corresponding container operation instruction, and then the modified content is saved to generate the corresponding current mirror image.
S503, judging whether all the partition modification content lists are traversed, if yes, executing S504, and if not, executing S505.
S504, determining the current mirror image as a target mirror image.
The embodiment relates to an application scenario in which the computer device traverses and completes all partition modification content lists, and the application scenario indicates that the computer device has completed modification to a container, so that the current mirror image obtained at this time is the target mirror image corresponding to the target container which is finally modified and stored.

The embodiment relates to an application scenario in which the computer device has not traversed and completed all partition modification content lists, and the application scenario indicates that the computer device has not completed modifying a container, so the computer device needs to continuously modify and save the container created by the current image based on the current image until all partition modification content lists are traversed and completed, and a target image is obtained.
The above embodiment is a process of iteratively modifying and saving the current target container, and each modification and saving of the current target container is performed on the basis of the current target container modified last time, so that the size of the current mirror image obtained after each modification and saving of the current target container does not exceed the preset threshold. The target images obtained through the iterative process not only contain all changes in the target container, but also each layer of images accords with the upper limit (preset threshold) of the size required by the cloud image warehouse for storing the single-layer images. Therefore, the container storage method provided by the application is not limited by the single-layer image storage of the conventional cloud image warehouse, and the corresponding image can be directly uploaded to the cloud image warehouse after the container is stored.

It will be appreciated that when the type of operation in which the computer device obtains the modified content for each row is a modification and the type of modified content for each row is a folder, the computer device need not perform any operation because the immediately following file modified content is the operation that is actually required to be performed under the folder.
S604, if the operation type of the modified content of each row is adding or modifying, and the type of the modified content of each row is a file, copying the content in the corresponding directory of the target container to the corresponding directory in the current target container.

S605, storing the modified current target container to obtain the current mirror image.
When the computer equipment obtains the modified current target container, the modified current target container can be saved through the container operation instruction related to the saved container issued by the authorities, and the mirror image corresponding to the current target container, namely the current mirror image, is obtained.
In the process of storing the container, each partition modifies each layer of content of the newly added target image when the content list corresponds to the container, so that the size of the newly added image layer obtained by modifying the content list according to each partition in the target image is smaller than a preset threshold.

S702, screening the modified contents of the readable and writable layer from all the modified contents to serve as target modified contents.
Further, the computer device may screen the real modification content of the readable/writable layer from all the modification content through the path of the readable/writable layer, so as to use the modification content as the target modification content for subsequent operations.
