Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as 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 provider and a deployment policy service application, for example, for a technical problem of enterprise B, enterprise a provides a solution for the technical problem, and converts the solution into a deployment policy and sends the deployment policy to enterprise B.

1. The deployment policy service provider comprises a management module and a storage module

1) Management module, including application management and deployment management

Firstly, application management, namely, an enterprise A inputs an application identifier, 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 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 can contain other installation items preset by the research and development personnel besides an application installation package;

II describes information management, including dependency management and configuration information management

and a, managing a dependency relationship, recording the sequential execution relationship between the current application and other applications in the application list, and later using the sequential execution relationship for computing the application execution sequence, wherein the application list comprises X, Y, Z three applications, for example, the X application is started first, the Y application is started second, and the Z application is started last.

And b, managing configuration information, managing information such as the identifier of the middleware, the middleware resource information and the script which are depended 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 } indicates the unique ID of the application middleware resource, mysql indicates the type of the resource, and name indicates that the field meaning is the user name. For example, database server information 4c8g 100g hard disk, this information is used for server applications. The script information is used for script initialization, such as database resource initialization by using the script through the API after the database application is completed.

And secondly, 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 the configuration information of the application;

2) and the OSS file server is used for storing the mirror image address, the mirror image information, the relied 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) And the control terminal is used for information synchronization, such as application of middleware resource information, analysis of application configuration files, deployment of applications and the like.

The method comprises the steps of firstly, resource application, analyzing configuration information of application to obtain an identifier of a middleware depended by the application, calling a middleware API to apply the middleware resource information to a server, and executing script information to finish initialization of the middleware under the condition that the middleware resource information is not inquired.

And step two, configuration replacement, namely replacing placeholders in the application configuration information with middleware resource information. If the placeholders of the account and the password in the application X are replaced by the account and the password of the middleware resource information, the dynamic and automatic resource replacement of the application is realized.

And thirdly, obtaining an application list corresponding to the deployment strategy by relying on calculation, determining the sequence of execution between each application and other applications according to the description information of each application, and then connecting the sequence in series to obtain an application execution sequence for scheduling the application starting sequence during deployment.

And fourthly, batch deployment, wherein after the configuration files of the mirror image information and the replacement resource information of the application are obtained, the Kubernets execute application deployment operation according to the application execution sequence in sequence.

2) The dependency environment, including the middleware environment for operation and maintenance deployment and the kubernets environment, is usually privatized to the application side.

Referring to fig. 2, a main flowchart of a method for deploying an application according to an embodiment of the present invention is shown, which includes the following steps:

s201: responding to the trigger deployment operation of a deployment strategy, acquiring an application list corresponding to the deployment strategy, and calculating an execution sequence among applications in the application list;

s202: determining a first application with a first sequence, and analyzing configuration information of the first application to obtain an identifier of a middleware which is depended on by the first application;

s203: 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 with the first application;

s204: repeating the above process, establishing communication link configuration information between the application and each application in the application list, and further executing application deployment operation step by step according to the execution sequence.

In the foregoing embodiment, for step S201, for the deployment policy service provider 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 supplier capability validation work performed by an enterprise prior to product selection or development of an externally implemented project. The enterprise B deploys the POC environment firstly, clicks a deployment option in a preset deployment application operation interface under the POC environment, and triggers the deployment operation of the deployment strategy. At present, deployment is triggered manually, and each deployment strategy is completed by a plurality of applications in an assisted manner, so that the acquired applications are generally in a list form, each piece of application information comprises a mirror image address and description information, and the description information comprises configuration information and dependency relationship information.

The execution of different applications has a sequence, for example, the commodity system is composed of three applications, namely, a commodity basic service, a commodity gateway and a commodity web, the commodity basic service is started firstly, then the commodity gateway is started, and finally the web is started. Generally, 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 indicated to be started independently, otherwise, the execution dependency relationship is executed in series in sequence, and the application execution sequence can be obtained.

For steps S202 and S203, a first application executed first is first determined. If the application execution sequence is in a non-closed loop form, the first application may be determined directly, but if closed, one application may be randomly selected as the first application and another application that precedes and is adjacent to the first application as the last application to execute. It should be noted that, in actual operation, a case of sequence interruption may occur (that is, the number of sequences is not 1), and at this time, a prompt message may be popped up, and manual patching or setting of the execution sequence may be performed. And in some cases, there is no execution dependency relationship between part of applications, for example, after the X application is executed, one of the Y application or the Z application is randomly started.

The configuration information of the first application is analyzed to obtain an identifier of the middleware depended on by the first application, such as MySQL database, and then middleware resource information, usually a login account and a password, is obtained from the MySQL, and then the configuration information in the first application is replaced by the middleware resource information. However, at this time, the solution is only the deployment phase, and is not yet started, so that the network http connection cannot be established, and therefore, only the communication link configuration information is established with the first application, which is convenient for the subsequent direct start.

In addition, referring to fig. 3, in order to specifically acquire the middleware resource information, the method includes:

s301: acquiring middleware description information corresponding to the middleware identification, 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: if not, initializing the middleware corresponding to the middleware identifier to obtain middleware resource information;

s304: and under the condition of obtaining the middleware resource information, replacing the placeholder in the first application configuration information with the middleware resource information.

The method comprises the steps of acquiring attribute information of the middleware according to the middleware description information, such as a table name and a library name, inquiring whether middleware resource information corresponding to the middleware attribute information, such as an account number and a password, exists, if the middleware resource information does not exist, calling a related interface to initialize, recording a configuration relation between the middleware resource information and first application configuration information, and finishing initialization of a first application configuration file (namely configuration information after resource replacement).

For step S204, after a communication link configuration relationship is established with each application in the deployment policy application list, a deployment pushing interface is called, a mirror address and a configuration file of each application are pushed to the deployment platform, and the applications are deployed step by using the deployment platform according to the application execution sequence.

Referring to FIG. 4:

s401: calling a deployment push interface of a deployment policy service provider, acquiring a mirror image address from information of each application and pushing the mirror image address to a deployment platform so as to trigger the deployment platform to load corresponding mirror image information based on the mirror image address;

s402: acquiring a configuration file after resource information is replaced from the information of each application, and pushing the configuration file to the deployment platform;

s403: and dynamically loading the configuration files of the applications when the deployment platform is used for starting the mirror image information of the applications in a mirror image manner so as to execute the deployment operation of the applications step by step according to the execution sequence.

The Kubernetes deployment platform loads application image information from an API (application programming interface) at a deployment policy service providing end based on an image address, and replaces a configuration file. The configuration file and the image information of each application are usually stored in the same position, so when the image information of one application is started by an image, the kubernets deployment platform loads the configuration file of the application from the position of the image information.

Further, a plurality of deployment policies may exist in the POC environment, and each policy is considered to be formed by combining a plurality of applications, and each application includes a plurality of services, so that a deployment group may be created in a deployment platform kubernets, and a deployment system is provided in the group, and includes a plurality of deployment files for separately storing the image information and the configuration file of each application.

In the method provided by the embodiment, the service provider quickly manages the application information and maintains the application information to the system management platform in a manner of separating the mirror image information from the configuration information, and the service provider applies for the middleware resource information by analyzing the application configuration information so as to dynamically modify the application configuration information, thereby deploying the POC related applications according to the dependency relationship between the applications. The configuration and resources of the application can be managed quickly as a whole, manual operation (such as application of middleware resources, modification of configuration information, manual mirror image moving and the like) is reduced when the application is installed, the automation of the POC deployment process is realized, and the deployment efficiency is greatly improved.
