Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and device for deploying applications. Background Art

[0002] Application deployment refers to the process of deploying packaged application resources to a designated server according to a series of orchestrated task flows. To improve the speed and efficiency of application deployment, companies currently typically build a Proof of Concept (POC) environment before deploying basic middleware and deploying applications in this environment when providing external commercial capabilities and engaging with key account (KA) users.

[0003] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0004] 1. Each service in the application needs to be deployed separately. First, relevant resources such as account numbers and passwords must be requested from the middleware. Then, the application configuration files must be manually converted. This results in extremely low configuration efficiency and a high learning cost for this deployment method.

[0005] 2. The order of application execution has a strong dependency, but in actual operation, there may be situations where service names are different, services are not registered, or do not exist. This may cause some applications / services to fail to start, requiring the modification of a large number of application configuration files, affecting the overall deployment speed.

[0006] 3. In some scenarios, scripting languages ​​are used for application deployment. However, the middleware resource information that the application depends on needs to be customized and developed. If scripting languages ​​are used to describe and write information, the writing process is more complicated and the writing cycle is longer, resulting in low deployment efficiency.

[0070] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0071] As shown in Figures 1(a) and (b), this solution includes a deployment policy service provider and a deployment policy service application. For example, in response to a technical problem faced by enterprise B, enterprise A provides a solution and converts the solution into a deployment policy and sends it to enterprise B.

[0072] 1. Deployment of policy service provider, including management module and storage module

[0073] 1) Management module, including application management and deployment management

[0074] ① Application management: Enterprise A enters the application identifiers and application information used in the deployment strategy into the system management platform to generate an application list for the deployment strategy;

[0075] I Image address management, set by the R&D personnel, the subsequent deployment platform can load the application image information based on the image address. The application image information here includes not only the application installation package, but also other installation items preset by the R&D personnel;

[0076] II describes information management, including dependency management and configuration information management

[0077] a Dependency management: record the execution order of the current application and other applications in the application list. This is later used to calculate the application execution sequence. For example, if the application list contains three applications, X, Y, and Z, application X will be started first, application Y will be started second, and application Z will be started last.

[0078] b. Configuration information management: This involves managing the identifiers, middleware resources, and scripts of each application's dependent middleware. This information is then converted into pre-set templates. For example, in the database, the resource ID in {resource ID.mysql.name} represents the unique ID for the requested middleware resource, mysql represents the resource type, and name represents the username. For example, database server information such as 4c8g and a 100g hard drive is used for server applications. Script information is used for script initialization. For example, after a database application is completed, a script can be used to initialize database resources through the API.

[0079] ② Deployment management: set up a deployment push interface, through which the application's image address and configuration information are pushed to the application-side deployment platform for resource initialization and deployment operations.

[0080] 2) Storage Module

[0081] 1) MYSQL server, used to store application configuration information;

[0082] 2) OSS file server, used to store the application's image address, image information, and dependent middleware resource information.

[0083] 2. Deployment strategy service application side, including control side and dependent environment

[0084] 1) The control side is used for information synchronization, such as applying for middleware resource information, parsing application configuration files, and deploying applications.

[0085] ① Resource application: parse the application configuration information to obtain the identifier of the middleware that the application depends on, call the middleware API to apply for middleware resource information from the server, and if no middleware resource information is found, execute the script information to complete the initialization of the middleware.

[0086] ② Configuration replacement: Replace the placeholders in the application configuration information with the middleware resource information. For example, replace the placeholders for the account and password in application X with the account and password in the middleware resource information, thereby achieving dynamic and automatic resource replacement for the application.

[0087] ③Dependency calculation, obtain the application list corresponding to the deployment strategy, determine the execution order between each application and other applications based on the description information of each application, and then concatenate the application execution sequence to schedule the application startup order during deployment.

[0088] ④ Batch deployment: After obtaining the application image information and the configuration file that replaces the resource information, Kubernetes executes the application deployment operations in sequence according to the application execution order.

[0089] 2) Dependent environments, including the middleware environment and Kubernetes environment used for operation and maintenance deployment, which are usually privatized on the application side.

[0090] See also Figure 2 , which shows a main flow chart of a method for deploying an application provided by an embodiment of the present invention, including the following steps:

[0091] S201: In response to a deployment triggering operation on a deployment policy, obtaining an application list corresponding to the deployment policy, and calculating an execution order between applications in the application list;

[0092] S202: Determine a first application ranked first, parse configuration information of the first application, and obtain an identifier of a middleware on which the first application depends;

[0093] S203: Acquire middleware resource information corresponding to the identifier, and replace the placeholder in the configuration information with the middleware resource information to establish communication link configuration information with the first application;

[0094] S204: Repeat the above process to establish communication link configuration information with each application in the application list, and then gradually perform application deployment operations according to the execution order.

[0095] In the above implementation, for step S201, the deployment policy service provider is used to provide deployment policy services to the deployment policy service application. For example, for a technical problem of enterprise B, enterprise A provides a solution and converts the solution into a deployment policy and sends it to enterprise B.

[0096] A proof-of-concept (POC) environment is typically used by companies to verify product or supplier capabilities before selecting products or launching external implementation projects. Company B first deploys a POC environment and then clicks the Deploy option in the pre-set deployment application interface to trigger the deployment of the deployment policy. Currently, deployments are manually triggered, and each deployment policy is supported by multiple applications. Therefore, the applications retrieved are generally presented as a list. Each application includes an image address and a description, which in turn includes configuration information and dependency information.

[0097] Applications execute sequentially. For example, if a product system consists of three applications: the product basic service, the product gateway, and the product web, the product basic service starts first, followed by the product gateway, and finally the web. The execution dependencies between applications are typically maintained in their descriptions. If no description exists, the application is started independently. Otherwise, the application execution sequence is determined by sequentially linking the execution dependencies.

[0098] For steps S202 and S203, the first application to be executed is first determined. If the application execution sequence is not a closed loop, the first application can be directly determined. However, if it is a closed loop, an application can be randomly selected as the first application, and another application that is located before and adjacent to the first application can be selected as the last application to be executed. It should be noted that in actual operation, the sequence may be interrupted (i.e., the number of sequences is not 1). In this case, a prompt message will pop up, and the user can manually repair it or set the execution order. In some cases, there is no execution dependency between some applications. For example, after application X is executed, one of application Y or application Z is randomly started.

[0099] The first application's configuration information is parsed to obtain the identifier of the middleware it relies on, such as the MySQL database. The middleware resource information, typically the login account and password, is then retrieved from MySQL. The configuration information in the first application is then replaced with the middleware resource information. However, at this point, the solution is only in the deployment phase and has not yet been started, so a network HTTP connection cannot be established. Therefore, only the communication link configuration information is established with the first application to facilitate subsequent direct startup.

[0100] Also, see Figure 3 As shown in the figure, the specific method for obtaining middleware resource information is:

[0101] S301: Acquire middleware description information corresponding to the middleware identifier, and parse the middleware description information to obtain middleware attribute information;

[0102] S302: Query whether there is middleware resource information corresponding to the middleware attribute information;

[0103] S303: If it does not exist, initialize the middleware corresponding to the middleware identifier and obtain middleware resource information;

[0104] S304: When the middleware resource information is obtained, the placeholder in the first application configuration information is replaced with the middleware resource information.

[0105] According to the middleware description information, the attribute information of the middleware can be obtained, such as the table name and library name, and whether there is middleware resource information corresponding to the middleware attribute information, such as account number and password, is queried. If not, it is necessary to call the relevant interface to initialize it and record the configuration relationship between the middleware resource information and the first application configuration information. At this time, the initialization of the first application configuration file (that is, the configuration information after replacing the resource) is completed.

[0106] For step S204, after establishing a communication link configuration relationship with each application in the deployment strategy application list, the deployment push interface is called to push the image address and configuration file of each application to the deployment platform, and the deployment platform is used to gradually deploy the applications according to the application execution order.

[0107] See also Figure 4 As shown:

[0108] S401: calling the deployment push interface of the deployment policy service provider, obtaining the image address from the information of each application and pushing it to the deployment platform, so as to trigger the deployment platform to load the corresponding image information based on the image address;

[0109] S402: Obtain a configuration file after replacing resource information from the information of each application, and push the configuration file to the deployment platform;

[0110] S403: Utilizing the deployment platform to dynamically load the configuration files of each application when mirroring and starting the mirror information of each application, so as to gradually execute the application deployment operation according to the execution order.

[0111] Based on the image address, the Kubernetes deployment platform loads the application image information from the API provided by the deployment policy service, replacing the configuration file. Each application's configuration file and image information are typically stored in the same location. Therefore, when the Kubernetes deployment platform starts an application image, it loads the application configuration file from the image's location.

[0112] Furthermore, there may be multiple deployment strategies in the POC environment. Considering that each strategy is composed of multiple applications and each application contains multiple services, deployment groups can also be created in the deployment platform Kubernetes. A deployment system is set up in the group, and the deployment system contains multiple deployment files for separately storing the image information and configuration files of each application.

[0113] In the method provided by the above embodiment, the service provider quickly manages application information and maintains it on the system management platform by separating image information and configuration information. The service application provider parses the application configuration information to apply for middleware resource information, dynamically modifying the application configuration information and then deploying POC-related applications based on the dependencies between applications. This allows for rapid management of application configuration and resources, reducing manual operations during application installation (such as applying for middleware resources, modifying configuration information, and manually relocating images), automating the POC deployment process, and significantly improving deployment efficiency.
