Question

我正在使用来自插件网站https://wiki.jenkins.io/display/JENKINS/Docker+Plugin的常规脚本代码来设置Jenkins Docker插件一切都按需工作，但是脚本设计为使用单个docker模板创建单个docker cloud。当然，我可以手动将新的docker模板添加到现有的docker cloud中，但是我想使用Groovy脚本使其工作。或者，或者，如果可以使用相同的Groovy脚本使用多个Docker模板创建单个Docker云。

我尝试通过将def DockerTemplateParameters和def dockerTemplateBaseParameters模板添加到具有不同值参数的现有dockerCloud模板中来添加一个模板，但是脚本无法以这种方式工作...

远远低于我的尝试（仍然无法正常工作）：

我已经使用上述凹槽脚本创建了云。现在，我尝试使用@OliverGondža建议中的代码向其添加另一个docker模板：

  AndroidTemplateParameters.instanceCapStr
))


// save current Jenkins state to disk
jenkins.save()

当我尝试在Jenkins脚本控制台中运行以上代码时，出现以下错误：

java.lang.NullPointerException：无法调用方法addTemplate（）空对象

需要帮助修复此代码并使其起作用。先感谢您，伊戈尔。

您可以通过created () { this.data = JSON.parse(JSON.stringify(this.rt)); },访问已配置的云，以找到要更新的云。您可以通过调用jenkins.clouds.getByName(String)向其添加更多模板。完成后，请记住保存Jenkins。大概是这样的：

DockerCloud.addTemplate(DockerTemplate)

使用Groovy脚本在Jenkins中自动配置Docker云
