使用Dockerfile（IntelliJ）部署Google Flexible App Engine

Question

我无法通过IntelliJ将Java应用程序部署到App Engine（灵活）。

我从这个“基于Spring Boot的Hello World应用程序”教程开始

https://github.com/GoogleCloudPlatform/getting-started-java/tree/master/helloworld-springboot

我成功完成了操作（并将Hello World应用程序作为灵活的应用程序部署到我的GCP项目中）。

然后，我将所有服务（我尝试迁移的Java应用程序中的服务）添加到此框架中。

我有一个密钥文件需要在服务初始化时读取，因此我将其添加到了Docker文件中（在./src/main/docker/目录下）：

我的Dockerfile

FROM openjdk:8-jre-alpine
RUN mkdir -p src/main/resources/
ADD keyfile.p12 src/main/resources/keyfile.p12
FROM google/cloud-sdk:alpine
RUN apk --update add openjdk8-jre
RUN gcloud components update

我的app.yaml文件

runtime: custom
env: flex

runtime_config:  # Optional
  jdk: openjdk8

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

manual_scaling:
  instances: 1

它编译。但是，当我尝试部署它（通过终端“ mvn appengine：deploy”或通过IntelliJ“ Google Cloud Tools->部署到App Engine”）时，它在应用程序启动时失败...

我在这里做错了什么？

Answer 1

您的Dockerfile似乎有几个问题-多个无关的FROM；没有ENTRYPOINT来运行您的jar

我成功测试了使用Cloud Tools for IntelliJ使用生成的jar Dockerfile将您的应用程序部署到App Engine flexible的步骤，

首先重命名您当前的Dockerfile，以便我们可以生成一个新文件。然后在Project Structure-> Facets-> App Engine Flexible下，生成一个新的Dockerfile：

在弹出的对话框中，请确保选择“ JAR”类型。

然后，在src/main/docker下，您将找到生成的Dockerfile：

FROM gcr.io/google_appengine/openjdk
# Replace occurrences of YOUR_ARTIFACT_NAME_HERE with the name of the deployed jar
ADD YOUR_ARTIFACT_NAME_HERE.jar /app/
ENTRYPOINT ["/docker-entrypoint.bash"]
CMD ["java","-jar","/app/YOUR_ARTIFACT_NAME_HERE.jar"]

如Dockerfile中所示，将占位符更新为构建的jar文件的名称（例如helloworld-springboot-0.0.1-SNAPSHOT.jar或您对其进行自定义的任何名称）。

使用此生成的文件作为起点（添加任何文件等），根据应用程序的需要自定义Dockerfile。

然后，使用Tools > Google Cloud Tools > Deploy to App Engine..，您应该会看到类似以下内容（正确指向您的app.yaml和Dockerfile）：

运行部署，希望这次能够成功。
