[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0023] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] The terms used in the present invention are only used to describe specific embodiments and are not intended to limit the present invention. As used in the present invention, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0025] When the terms “comprising” and / or “made of…” are used in the present invention, it specifies the existence of the stated features, integers, steps, operations, elements and / or components, but does not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used in the present invention have the same meaning as those commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present invention, and will not be interpreted as having an idealized or overly formal meaning unless the present invention clearly defines it as such.

[0027] In a first aspect, an embodiment of the present invention provides an automated operation and maintenance method, including:

[0028] S110, assembling the information set and the template in the configuration file to obtain multiple instruction files, where the information set includes multiple information, and each information corresponds to one instruction file;

[0029] Among them, the configuration template can be specifically a yaml public configuration template. In a specific implementation of the present application, four variables, namely province, application, startup mode, and number of channels, are extracted in combination with the characteristics of the current billing and settlement convergence service, and the four variables are edited into the yaml public configuration template. The yaml public configuration template sets the province, application, startup mode, and number of channels as replaceable variables.

[0030] When there is a demand for service creation, the staff only needs to fill in the configuration file first. The configuration file can be in the info.cfg format. The staff can fill in the corresponding data in the configuration file in the format of "province, application, startup mode, number of channels". Among them, the information includes at least one set of corresponding data. When batch creation of services is required, multiple lines of data can be filled in the configuration file. Each information includes a line of data, that is, each information can include province, application, startup mode, number of channels. The information set includes at least one information.

[0031] During the assembly process, the information in the configuration file is read, and the instruction file is generated based on the information and the configuration template. Specifically, the province, application, startup mode, number of channels and other data in each information can be filled into the configuration template to generate the instruction file. Exemplarily, the information is filled into the yaml public configuration template to generate the instruction file, and the instruction file can be specifically a yaml file. The instruction file can be uniformly stored in a directory, and the directory can be specifically a bak directory.

[0032] S120. Create services in batches according to multiple instruction files.

[0033] The command file can create services in batches through K8S. Specifically, a service may include one or more applications to complete the service. The service creation process configures the application according to the province, startup mode, number of channels and other data in the command file so that the configured application can meet the service requirements. The method of creating a service by K8S can refer to the existing technology and will not be repeated here.

[0034] During the use of the service, the service may become abnormal or crash due to hardware or software reasons. In this case, the service needs to be restarted or even recreated. In order to shorten the abnormality processing time, the instruction file used to create the service needs to be backed up. However, during the actual operation, the loss of instruction files due to downtime or accidental deletion by staff will cause the service to be unable to recover.

[0035] In some embodiments, the automated operation and maintenance method further includes:

[0036] Output command files to remote storage area;

[0037] The instruction file can be output to the remote storage area for permanent storage by means of scheduled upload. Of course, the user can also upload the instruction file in real time or other upload methods, which are not limited here. The remote storage area can specifically be SVN (Subversion, version control system). Of course, the remote storage area can also be in other forms, which are not limited here. The time interval for uploading the instruction file can be set according to the needs of the user, and the version of the instruction file in the remote storage area should be synchronized with the version of the local instruction file.

[0038] In response to detecting that an abnormality has occurred in the service, obtaining a command file from a remote storage area;

[0039] Update the local instruction file according to the instruction file in the remote storage area;

[0040] Since the instruction file in the remote storage area is backed up by the local instruction file before the exception occurs, the local instruction file can be updated to the latest version according to the instruction file in the remote storage area. Of course, the user can also use other historical instruction file versions in the remote storage area to update the local instruction file, which is not limited here.

[0041] Recreate the service according to the locally updated instruction file.

[0042] After the service is recreated, the service function can be restored. This improves the efficiency of automated operation and maintenance, shortens service downtime, and helps improve service quality and customer experience.

[0043] In this embodiment, the automated operation and maintenance method assembles multiple instruction files by configuring the template and the information set of the configuration file, and then creates services according to the multiple instruction files. This can realize batch creation of services, improve service creation efficiency, realize automated operation and maintenance, and reduce manpower consumption.

[0044] In the prior art, the native interface cannot complete batch operations, and staff can only operate manually, which affects maintenance efficiency and consumes a lot of manpower.

[0045] In some embodiments, the automated operation and maintenance method can be used to batch manage existing applications, and the instruction file includes the application name, conditional parameters, and the number of channels. The conditional parameters may include data such as the province and the startup mode, and the startup mode may include one of immediate startup, delayed startup, or conditional startup. The automated operation and maintenance method also includes:

[0046] In response to the received control instruction, searching for a target instruction file from a plurality of instruction files according to an application name and a condition parameter in the control instruction;

[0047] Control instructions can be issued according to staff operations or system settings. After receiving the control instructions, existing applications can be operated according to the control instructions, such as batch start or batch stop. Specific control instructions may include the required operation, application name, startup mode, and province. For example, the operation instruction can be specific to start "application|startup mode|province", stop "application|startup mode|province", etc. to start or stop a specific application. The operation instruction can also be start ALL or stop ALL to start and stop all applications.

[0048] The command file includes information, which may include data such as the name of the application, conditional parameters, number of channels, etc. The conditional parameters may include data such as province, startup mode, etc. The target command file corresponding to the application name can be searched.

[0049] Read the number of channels in the target instruction file;

[0050] The target instruction file includes the application and its channel number, so the corresponding channel number can be read from the target instruction file.

[0051] The applications corresponding to the application names in the control instructions are processed in batches according to the condition parameters and the number of channels.

[0052] Batch process applications based on conditional parameters and channel numbers. For example, batch start or batch stop applications based on provinces, startup modes, and channel numbers. This enables batch start and stop of applications, improves the operation and maintenance efficiency of staff, and reduces the workload of staff and the labor costs of enterprises.

[0053] The prior art requires updating applications one by one, which has low update efficiency and high operation and maintenance costs. In some embodiments, the instruction file includes the application name and version number, and the automated operation and maintenance method further includes:

[0054] In response to the received upgrade instruction, updating the version number in the instruction file according to the version number in the upgrade instruction;

[0055] The version number to be updated in the upgrade instruction. Before upgrading, the version number in the instruction file is replaced by the version number in the upgrade instruction, thereby updating the version number in the instruction file.

[0056] Pull the target image from the image repository according to the updated instruction file;

[0057] The target image is an update file corresponding to the version number in the upgrade instruction, and the update file can be pre-stored in the image warehouse.

[0058] Use the target image to batch update applications.

[0059] After the version number in the instruction file is updated, when the application is started again, the target image pre-stored in the image repository can be found according to the version number in the instruction file, and the target image can be started to complete the batch update of the application.

[0060] In a specific implementation of the present application, the upgrade instruction may be in the form of updateimages "application|startup mode|province:image tag", where the application may be specifically the application name, and the image tag may include the version number to be updated. After receiving the upgrade instruction, batch image upgrades can be performed according to the application, startup mode, and province dimensions. Of course, the upgrade instruction may also take other forms, for example, updateimages "ALL:image tag" can be used to implement a full image upgrade.

[0061] This embodiment updates the version number in the instruction file through the upgrade instruction, so that when the application starts, it can pull the target image pre-stored in the image warehouse, and batch update the application through the target image, which improves the update efficiency of the application, reduces the manpower consumption in the operation and maintenance process, and reduces the manpower cost of the enterprise.

[0062] As services are promoted, the demand for services increases accordingly. When creating services, the number of application channels often cannot meet the demand, so the application channels need to be expanded. Existing technologies often require manual expansion of the number of application channels, which has the problems of low expansion efficiency and high labor consumption.

[0063] In some embodiments, the instruction file includes an application name, conditional parameters, and a number of channels. The conditional parameters may include data such as a province and a startup mode. The startup mode may include immediate startup, delayed startup, or conditional startup. The automated operation and maintenance method also includes:

[0064] In response to the received adjustment instruction, searching for a target instruction file from a plurality of instruction files according to the application name and condition parameters in the adjustment instruction; updating the number of channels in the target instruction file according to the number of channels in the adjustment instruction;

[0065] The adjustment instruction may include an application name, conditional parameters and the number of channels. The application name and conditional parameters correspond to the application name and conditional parameters in the instruction file. Therefore, the target instruction file can be found according to the application name and conditional parameters, and the number of channels in the target instruction file can be updated according to the number of channels in the adjustment instruction. Thus, the number of channels in the target instruction file can be changed.

[0066] It should be noted that the number of channels in the adjustment instruction can be greater than the number of channels in the target instruction file, or less than the number of channels in the target instruction file. When the number of channels in the adjustment instruction is greater than the number of channels in the target instruction file, it is called channel expansion; when the number of channels in the adjustment instruction is less than the number of channels in the target instruction file, it is called channel reduction. When the service demand increases, the staff can perform channel expansion operations; when the service demand decreases, the staff can perform channel reduction operations.

[0067] According to the updated target instruction file, applications corresponding to the application names in the control instruction are started in batches.

[0068] After the target instruction file is updated, the number of channels therein is the updated number of channels. After the application is restarted, the number of channels of the relevant application is equal to the updated number of channels, thereby achieving adjustment of the number of channels of the application.

[0069] In this embodiment, the automated operation and maintenance method updates the number of channels in the target instruction file by adjusting the instruction, and when restarting the application, the application is started according to the updated number of channels. This achieves batch adjustment of the number of application channels, improves the automation level of operation and maintenance, improves the efficiency of operation and maintenance, and reduces the manpower consumption of the operation and maintenance process.

[0070] As described in the above embodiments, the present application can update, expand and shrink channels, and update the command file during the operation. The automated operation and maintenance method provided by the present application also includes:

[0071] Before updating the command file, back up the original command file.

[0072] The original command file can be backed up to the bak directory or to a remote storage area. If an abnormal situation occurs when creating a service with an updated command file, the service can be recreated with the backed-up original command file to ensure normal operation of the service.

[0073] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
