Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1 (a) and (B), the solution includes a deployment policy service providing end and a deployment policy service application end, for example, for a technical problem of enterprise B, enterprise a provides a solution for the deployment policy service providing end and converts the solution into a deployment policy and sends the deployment policy to enterprise B.
1. The deployment strategy service providing end comprises a management module and a storage module
1) Management module including application management and deployment management
① Application management, wherein an enterprise A inputs application identifiers, application information and the like used by a deployment strategy into a system management platform so as to generate an application list aiming at the deployment strategy;
i mirror image address management is set by a research and development personnel, a subsequent deployment platform can load application mirror image information according to the mirror image address, and the application mirror image information comprises an application installation package and other installation items preset by the research and development personnel;
II descriptive information management including dependency management and configuration information management
And a, managing the dependency relationship, inputting the execution relationship between the current application and other applications in an application list, and later calculating the application execution sequence for use, wherein the application list comprises X, Y, Z applications, the X application is started firstly, the Y application is started secondly, and the Z application is started finally.
B, managing configuration information, managing information such as the identification of the middleware, the middleware resource information, the script and the like which are relied by each application, and converting the middleware resource information into a preset template form. Taking the database as an example, the resource ID in { resource ID. Mysql. Name } represents the unique ID of the application middleware resource, mysql represents the type of resource, and name represents the field meaning a user name. For example, database server information 4c8g 100g hard disk, which is used for server applications. The script information is used for initializing the script, and the database resource is initialized by utilizing the script through the API after the database application is completed.
② And (3) deployment management, namely setting a deployment pushing interface, and pushing the mirror image address and the configuration information of the application to an application end deployment platform through the interface to perform resource initialization and deployment operation.
2) Memory module
1) The MYSQL server is used for storing configuration information of the application;
2) The OSS file server is used for storing the mirror address, mirror information, the dependent middleware resource information and the like of the application.
2. The deployment strategy service application end comprises a control end and a dependent environment
1) The control end is used for information synchronization, such as application of middleware resource information, analysis of application configuration files, deployment of applications and the like.
① And (3) applying for the resources, analyzing the configuration information of the application to obtain the identification of the middleware on which the application depends, calling a middleware API to apply for the middleware resource information from the server, and executing script information to complete the initialization of the middleware under the condition that the middleware resource information is not queried.
② And (3) configuration replacement, namely replacing placeholders in the application configuration information with middleware resource information. If the placeholder of the account number and the password in the application X is replaced by the account number and the password of the middleware resource information, the dynamic and automatic resource replacement of the application is realized.
③ And depending on calculation, acquiring an application list corresponding to the deployment strategy, determining the sequence of execution between each application and other applications according to the description information of each application, and further connecting the application execution sequences in series to obtain an application execution sequence for scheduling the application starting sequence during deployment.
④ After the image information of the application and the configuration file of the replacement resource information are acquired, the Kubernetes sequentially execute application deployment operation according to the application execution sequence.
2) Depending on the environment, including the middleware environment and the Kubernetes environment to run and maintain deployment, application-side privacy is common.
Referring to fig. 2, a main flowchart of a method for deploying an application according to an embodiment of the present invention is shown, including the following steps:
s201, responding to triggering deployment operation of a deployment strategy, acquiring an application list corresponding to the deployment strategy, and calculating the execution sequence among all applications in the application list;
s202, determining a first application of which the first is ordered, and analyzing configuration information of the first application to obtain an identifier of a middleware on which the first application depends;
S203, middleware resource information corresponding to the identifier is obtained, and placeholders in the configuration information are replaced by the middleware resource information so as to establish communication link configuration information between the configuration information and the first application;
s204, repeating the process, establishing communication link configuration information between each application in the application list, and further gradually executing application deployment operation according to the execution sequence.
In the above embodiment, for step S201, for the deployment policy service provider, the deployment policy service provider is configured to provide the deployment policy service for the deployment policy service application, for example, for a technical problem of enterprise B, enterprise a provides a solution for the deployment policy service provider, and converts the solution into a deployment policy and sends the deployment policy to enterprise B.
POC environments are typically a product or vendor capability verification effort that an enterprise performs before performing product typing or developing external implementation projects. The enterprise B deploys the POC environment at first, clicks deployment options in a preset deployment application operation interface under the POC environment, and triggers deployment operation on deployment strategies. At present, deployment is manually triggered by manpower, and each deployment strategy is assisted by a plurality of applications, so that the acquired applications are generally in a list form, each application information comprises a mirror image address and description information, and the description information comprises configuration information and dependency information.
The execution of different applications has a sequence, for example, a commodity system consists of three applications, namely commodity basic service, commodity gateway and commodity web, wherein the commodity basic service is started first, then the commodity gateway is started, and finally the web is started. And the execution dependency relationship between the application and other applications is maintained in the description information, if the description information does not exist, the application is started independently, otherwise, the execution dependency relationship is serially executed in sequence to obtain an application execution sequence.
For steps S202 and S203, a first executed first application is first determined. If the application execution sequence is in a non-closed loop form, the first application can be directly determined, but if the application execution sequence is in a closed loop form, one application can be randomly selected as the first application, and the other application which is positioned before the first application and is adjacent to the first application can be used as the last executed application. It should be noted that, in the actual operation, a sequence interrupt may occur (i.e., the number of sequences is not 1), and at this time, a prompt message may be popped up, and repair may be performed manually or the execution sequence may be set. And in some cases, there is no execution dependency relationship between some applications, for example, after the execution of the X application is completed, one of the Y application or the Z application is started randomly.
Analyzing the configuration information of the first application to obtain the identification of the middleware on which the first application depends, such as a database MySQL, further obtaining middleware resource information, usually a login account and a password, from the MySQL, and then replacing the configuration information in the first application with the middleware resource information. However, the solution is only in the deployment stage and is not started, so that the network http connection cannot be established, and the communication link configuration information is only established with the first application, so that the subsequent direct start is facilitated.
In addition, referring to fig. 3, a specific method for acquiring middleware resource information is as follows:
S301, acquiring middleware description information corresponding to a middleware identifier, and analyzing the middleware description information to obtain middleware attribute information;
S302, inquiring whether middleware resource information corresponding to the middleware attribute information exists or not;
s303, initializing a middleware corresponding to the middleware identifier if the middleware does not exist, and obtaining middleware resource information;
and S304, under the condition that the middleware resource information is obtained, replacing the placeholder in the first application configuration information with the middleware resource information.
According to the middleware description information, the attribute information of the middleware, such as a table name and a library name, whether the middleware resource information, such as an account number and a password, corresponding to the middleware attribute information exists or not is inquired, if the middleware resource information does not exist, the related interface is required to be called for initialization, the configuration relation between the middleware resource information and the first application configuration information is recorded, and at the moment, the initialization of the first application configuration file (namely, the configuration information after replacing the resources) is completed.
For step S204, after establishing a communication link configuration relationship with each application in the deployment policy application list, a deployment pushing interface is invoked to push the mirror address and configuration file of each application to the deployment platform, and the deployment platform is utilized to gradually deploy the applications according to the application execution sequence.
See fig. 4:
s401, calling a deployment pushing interface of a deployment strategy service providing end, acquiring a mirror image address from information of each application, pushing the mirror image address to a deployment platform, and triggering the deployment platform to load corresponding mirror image information based on the mirror image address;
S402, acquiring configuration files after replacing resource information from the information of each application, and pushing the configuration files to the deployment platform;
S403, dynamically loading configuration files of each application when the deployment platform is used for mirroring the mirror information of each application, so as to gradually execute application deployment operation according to the execution sequence.
The deployment platform Kubernetes loads application image information from an API interface at the deployment policy service provider based on the image address, and replaces the configuration file. The configuration file and the mirror image information of each application are usually stored in the same position, so that when the mirror image information of one application is started by the mirror image, the deployment platform Kubernetes loads the application configuration file from the position where the mirror image information is located.
Further, in the POC environment, there may be multiple deployment policies, and it is considered that each policy is formed by combining multiple applications, where each application further includes multiple services, so that a deployment packet may also be created in the deployment platform Kubernetes, where a deployment system is disposed in the packet, and the deployment system includes multiple deployment files for separately storing image information and configuration files of each application.
According to the method provided by the embodiment, the service provider rapidly manages the application information and maintains the application information to the system management platform in a mode of separating the mirror image information and the configuration information, and the service application side applies for middleware resource information by analyzing the application configuration information so as to dynamically modify the application configuration information and further deploy POC related applications according to the dependency relationship among the applications. The whole system can rapidly manage application configuration and resources, reduces manual operations (such as application of middleware resources, modification of configuration information, mirror image manual relocation and the like) when the application is installed, realizes POC deployment flow automation, and greatly improves deployment efficiency.

It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The described modules may also be provided in a processor, for example, a processor may be described as including a computation order module, a parse configuration module, a replacement information module, and a deployment application module. Where the names of the modules do not constitute a limitation on the module itself in some cases, for example, the deployment application module may also be described as "repeatedly operating and deploying the application module".
As a further aspect, the invention also provides a computer readable medium which may be comprised in the device described in the above embodiments or may be present alone without being fitted into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to include:
Responding to triggering deployment operation of a deployment strategy, acquiring an application list corresponding to the deployment strategy, and calculating the execution sequence among all applications in the application list;
Determining a first application of which the first is ordered, and analyzing configuration information of the first application to obtain an identifier of a middleware on which the first application depends;
Acquiring middleware resource information corresponding to the identifier, and replacing placeholders in the configuration information with the middleware resource information to establish communication link configuration information between the configuration information and the first application;
And repeating the process, establishing communication link configuration information between the application and each application in the application list, and further gradually executing application deployment operation according to the execution sequence.
According to the technical scheme of the embodiment of the invention, the application configuration and resources can be managed rapidly, manual operations (such as application middleware resources, configuration information modification, mirror image manual relocation and the like) are reduced when the application is installed, POC deployment flow automation is realized, and deployment efficiency is greatly improved.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
