Tap series article 9 | application development accelerator

background

For developers , Especially for new employees , There has always been a puzzle , That is how to start application development efficiently . Usually , The development department has accumulated over a certain period of time , There will be relevant development specifications and project specifications . How to make newcomers adapt to these norms as quickly as possible , How to build the project , How to write the configuration , What are the code dependency libraries , How to write notes and so on , Are issues to be addressed . otherwise , Each developer will write a variety of projects , In the end, no one can read it and can't take over , Let alone update maintenance . In a relatively standardized development team , Each project has general similarities with other projects , New members don't want to start from scratch every time , Can you stand on the shoulders of your predecessors ,“ reference ” Other similar projects , Take them as the template and basis , Follow up development ？ To find the answer to this question , We will first think of one called Spring Initializr Tools for . For the use of Spring Framework developers , It must be no stranger , Let's start with it .

Spring Initializr

If you want to build one from scratch Spring Boot Project , It's more complicated . You need to choose to create Maven still Gradle project ,Spring Boot Framework version ,JDK edition , And the dependencies that need to be used , These all need to be written into the project configuration file manually （ such as Maven The project is pom.xml）. besides , There is also metadata of the project, such as name , Package name , Group , Packaging methods, etc . in addition , The source code also needs to implement an annotation as SpringBootApplication Of Java Class and its main Method , And other fixed implementations , Such as unit test methods, etc .Spring In order to simplify this series of processes , But for Spring Boot The developer provides Spring Initializr Initial configuration tool . When it's turned on http://start.spring.io after , The following page appears ：

ad locum , We can set the above-mentioned parameters and metadata of the project through options and input , Then select the relevant dependent package , Finally, click Generate, Then one zip The package is generated and downloaded locally . Use common IDE Tools , such as IntelliJ IDEA, hold zip package import go in , A new beginning Spring Boot The project came into being , It greatly simplifies and accelerates the process of creating new projects .

TAP Application Accelerator

We have seen above Spring Initializr Yes Spring Help developers work . however Spring Initializr It still has its limitations , First of all, it is a public network Saas service , Cannot become the private template warehouse of the enterprise . secondly , It only supports Spring Boot Project , Other functions such as Go,C#,PHP,Node.js And other language frameworks . Last , Because it is a public service , You can't make some customized changes . therefore , These deficiencies must be improved , In order to build a privatized enterprise application template warehouse . Our solution is Tanzu Application Platform The built-in Application Accelerator （App Accelerator）.

We put every template Called an accelerator （Accelerator）. Let's take a look at how application developers use application accelerators to create an initial project . open TAP Of GUI Interface , I selected App Accelerator, You can see that many accelerator samples have been built in , Have use Spring,Node.js,C# wait , Here's the picture ：

Here we choose Tanzu Java Web App, It's a Spring Project template , You need to fill in some parameters , Such as project name , Image warehouse storage prefix and so on ：

Review the parameters and click Generate Accelerator：

A containing the initial project zip Package generated , Then you can download it back to the local ：

Will download zip Package in commonly used IDE, for example IntelliJ IDEA After opening in , It becomes an initial application project , The whole process is simple and fast ！

Create your own Application Accelerator

In the above example , As a developer, I have felt the convenience of using accelerator . So as an application architect , Creator role of template , How to create a self-made accelerator ？ The most convenient way is to customize an existing sample accelerator , Then generate a new accelerator . The sample accelerator can be found in https://github.com/sample-accelerators/ Here to find . Or to Spring Example accelerator , First, let's download the sample accelerator Tanzu Java Web App：git clone https://github.com/sample-accelerators/tanzu-java-web-app.git

In this Spring In the sample accelerator , The description file is accelerator.yaml, Let's take a look at some basic structures of the file ：

There is a display name in this section , describe , Icon and label settings .

This section contains the definition of input parameters .

In this section, there are settings for text replacement .

All descriptions of the accelerator can be referred to https://docs.vmware.com/en/Application-Accelerator-for-VMware-Tanzu/1.1/acc-docs/GUID-creating-accelerators-accelerator-yaml.html, I won't repeat it here .

To show the effect , We put display Name Change the name to My Tanzu Java Web App, Then push the whole accelerator to the private code base . Finally using Tanzu Command or use yaml File build your own accelerator , Example yaml The documents are as follows ：

The main setting here is git Warehouse address and branch name , And then use kubectl create The command yaml Configure import kubernetes. Once the successful , You can go through Acc Accelerator The new self-made accelerator can be seen in the management interface ：

Summary of the value of Application Accelerator After the development department set up the Application Accelerator , For new projects, project specifications and application development specifications can be set, and there are corresponding accelerators for reference . Development architects can summarize typical successful projects as templates and benchmarks , And released as an accelerator , Convenient for rapid promotion and replication . Which project did well , You can also contribute back to other project teams for reference . gradual , Accelerators in the development department are accumulating more and more , Finally, a rich and colorful application knowledge base will be formed .
