java - Spring Boot - 将应用程序部署到 Google Cloud App 引擎但缺少 app.yaml

Question

我有一个问题，我正在尝试解决这个问题。我正在尝试在谷歌云应用引擎上部署 spring boot 应用程序，但是当我尝试部署该应用程序时出现一个问题，我遇到了以下错误:

[INFO] --- spring-boot-maven-plugin:2.0.0.RELEASE:repackage (default) @ royAngularProject ---

请问我应该怎么做才能解决这个问题，抱歉我无法发布任何代码，因为我不知道问题出在哪里，如果我需要 app.yaml，我想指导我如何做将它安装到我的项目中。

Answer 1

在 java8 中开发的 maven 项目的标准 app.yaml 配置应如下所示；

runtime: java
env : flex
inbound_services: 
- warmup
derived_file_type:
- java_precompiled

runtime_config: 
  jdk: openjdk8

handlers:
- url: /.*
  script: this field is required, but ignored
skip_files: app.yaml

我认为 Google Cloud 平台的文档需要简化。
