Question

我正在使用maven和google cloud build构建我的spring boot应用程序，但是无论是使用setlocal set val=%1 if %val% LSS 0 ( set "sign=-" & set "val=%val:~1%" ) :loop if %val% GTR 999 (set newval=,%val:~-3%%newval% & set val=%val:~0,-3% goto loop ) echo %sign%%val:~-3%%newval%在本地运行还是使用Cloud Build部署，我都能以某种方式获得不同的部署结果。

如果我使用mvn appengine:run在本地运行，则可以按预期访问控制器。使用Cloud Build，我遇到了mvn appengine:run错误。

我的cloudbuild.yaml是以下内容：

您如何建议配置云构建，以便在Google App Engine上构建和部署Spring Boot应用程序？

在进一步挖掘之后，该问题似乎与返回的某种错误有关：

steps:
- name: 'gcr.io/cloud-builders/mvn'
  args: ['package']
- name: 'gcr.io/cloud-builders/gcloud'
  args: ['app', 'deploy', 'target/myapp/WEB-INF/appengine-web.xml']

使用javax.servlet.ServletContext log: 2 Spring WebApplicationInitializers detected on classpath从本地计算机进行部署时，在堆栈跟踪中未收到此消息

我的问题仍然存在，如何创建可以调用mvn appengine:deploy的{{1}}？

为了构建一个春季启动项目，并使用Google Cloud Build将其部署到google appengine。我最终不得不首先使用下图构建“构建器”图像，并在执行实际的应用程序构建时引用该图像。

我的spring boot项目的cloudbuild.yaml现在引用此图像：

steps:

  args: ['mvn', 'appengine:deploy']

我将尝试将此docker映像放在dockerhub和github上，以供其他人查找。我还将感谢更熟悉docker和linux的人们，以帮助改善该映像以减小其大小。（例如，使用Alpine代替Debian或Debian Stretch Slim）。同时，我希望这会对像我这样的人有所帮助。
