插件开发

插件包括一下几种:

插件类型 kind标识 说明
执行器 executor 在部署时被执行
检查器 checker 完成某个步骤时,对结果检测

插件示例

盘古的插件是用yml格式定义的:

#插件版本
version: 1.0

metadata:
  #类型,必须
  #可选值:
  #1.executor:执行器
  #2.checker:检查器
  #3.deployment:部署

  kind: executor

  #定义插件名称,必须
  name: "git clone"

  #定义id,必须,不能有空格
  id: git_clone

  #定义插件描述,可以为空
  desc: git clone 插件

  #定义作者名字,必须
  author: javashop

  #定义作者的链接,可以为空
  author_url: "https://www.javamall.com.cn"

#定义要传输到服务器中的文件
#source是本地文件路径,以classpath为根目录的相对路径
#target是远程目标路径,可以使用${worksapce}变量
copy:
  - source: executor/git_clone/git_clone.sh
    target: ${workspace}/git_clone.sh

#定义要执行的命令
command:
  #定义命令的类型,目前支持ssh 命令,必须
  type : ssh
  exec :
   - "sh  ${workspace}/git_clone.sh"


#插件的配置项,可以是多个配置项,可以为空
#每个配置项,会在配置界面展示
#客户输入的值在解析命令的时候会通过$ {变量名}解析出来
#type支持:
#1、input :单行文本
#2、textarea:多行文本
config :
  item:
    title: 源码目标路径
    name: dir
    type: input
    htmlcss: "width:100px"

插件的存放

插件可以存放在两个位置:

1、源码的resources目录

2、打包后的jar同级plugins目录

子目录

目录 说明
executor 存放执行器yml文件
checker 存放检查器yml文件

插件可以是单独直接在相应的文件夹中,也可以自己独立一个文件夹存放,比如:

image-20210223165625929

如上图所示,"plugin-one"直接存放在executor目录中,"plugin-two"单独在一个文件夹中,一般地是这个插件还存在除了yml文件以外的文件所以单独存在一个文件夹比较方便。

插件的书写与测试

首先您需要熟悉git fork,可以参考下面的文档:

https://gitee.com/help/articles/4128#article-header0

第一步:Fork盘古插件仓库

请fork下面的仓库:

https://gitee.com/javashop/pangu-plugin

第二步:建立插件文件

在您fork的仓库中:

在resources目录中建立你的插件文件,如:/resources/executor/test.yml

编写插件

根据需求按规则编写yml文件,您可以参考这个示例插件

第三步:测试插件

使用如下代码测试插件:

@RunWith(SpringRunner.class)
@SpringBootTest()
@ComponentScan("com.enation.pangu")
public class PluginTest {

    /**
     * 插件业务类
     */
    @Autowired
    ExecutorManager executorManager;

    /**
     * ssh客户端
     */
    SshClient sshClient;


    /**
     * 环境变量
     */
    Map env = new HashMap();

    //环境变量
    String workspace = "/opt/workspace/";

    /**
     * 测试前构建ssh client及 workspace
     * @throws IOException
     */
    @Before
    public  void init() throws IOException {
        env.put("workspace",workspace);

        //在这里定义测试机的信息
        sshClient = SshClientFactory.createSsh("root", "123456", "192.168.2.55", 22);

        //先创建workspace
        sshClient.exec("mkdir -p "+ workspace,text->{
            out.println(text);
        });

    }

    /**
     * 测试结束后断开ssh连接
     * @throws IOException
     */
    @After
    public void clean() throws IOException {
        sshClient.disconnect();
    }



    /**
     * 执行器测试
     * @throws ScriptException
     */
    @Test
    public void gitClone() throws IOException {
        //环境变量

        env.put("username", "2323");
        env.put("password", "2323");
        env.put("git_url", "https://gitee.com/javashop/pangu.git");
        //执行插件,第一个参数时插件id,第二个参数是插件类型,第三个参数是环境变量,第四个参数是ssh客户端
        boolean result = executorManager.runExecutor("git_clone",PluginType.executor, env, sshClient);
        out.println(result);
    }

    /**
     * 检查器测试
     * @throws IOException
     */
    @Test
    public void checkerTest() throws IOException {
        //执行插件,第一个参数时插件id,第二个参数是插件类型,第三个参数是环境变量,第四个参数是ssh客户端      
        boolean result = executorManager.runExecutor("install_one", PluginType.checker, env, sshClient);
        out.println(result);
    }
}

注意:开发好的插件,需要在插件页面点击同步才会出现在相应的列表中
