使用Dockerfile(IntelliJ)部署Google Flexible App Engine

2020年10月4日 33点热度 0条评论

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

我设法成功完成(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。

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,当我尝试部署它时(通过终端“mvn appengine:deploy”或通过IntelliJ“Google Cloud Tools-> Deploy to App Engine”,它在应用程序启动时失败...

我在这里做错了什么?

菲利普

解决方案如下:

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

我通过以下步骤使用Cloud Tools for IntelliJ成功地测试了使用将您的应用程序部署到App Engine flexible以及生成的jar Dockerfile:

首先重命名您当前的Dockerfile,以便我们可以生成一个新的。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..您应该看到类似以下内容(正确指向您的app.yaml和Dockerfile):

ojit_a

运行部署,希望这次能够成功。
