如何部署servlet java maven web應用到雲運行？

Question

我成功地將 spring 啟動 web 應用程序部署到雲運行並且運行良好。

但是我無法將基於 maven java web 應用程序部署到雲運行中。

當我運行此命令“ gcloud run deploy --image gcr.io/gcloud-myapp/sample ”時，我得到了

部署失敗錯誤：(gcloud.run.deploy) Cloud Run 錯誤：容器無法啟動。 無法啟動然后偵聽 PORT 環境變量定義的端口。 此修訂的日志可能包含更多信息。

Dockerfile

# Use the official maven/Java 8 image to create a build artifact.
# https://hub.docker.com/_/maven
FROM maven:3.8-jdk-11 as builder

# Copy local code to the container image.

    WORKDIR /app
    COPY pom.xml .
    COPY src ./src
    
    # Build a release artifact.
    RUN mvn package -DskipTests
    
    # Use AdoptOpenJDK for base image.
    # It's important to use OpenJDK 8u191 or above that has container support enabled.
    # https://hub.docker.com/r/adoptopenjdk/openjdk8
    # https://docs.docker.com/develop/develop-images/multistage-build/#use-multi-stage-builds
    FROM adoptopenjdk/openjdk11:alpine-slim
    
    # Copy the jar to the production image from the builder stage.
    COPY --from=builder /app/target/sample*.war /sample.war
    
    EXPOSE 8080
    
    # Run the web service on container startup.
    CMD ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/sample.war","--host", "0.0.0.0", "-p", "8080"]

是否可以將基於servlet的maven java web應用部署到雲運行？

Answer 1

對於訪問此問題的任何人，我將分享 guillaume blaquiere 的一篇文章，他在其中提到了不同的 Java 框架以及它們如何與 Cloud Run 一起工作。 我建議你 go 到這個GitHub 頁面，克隆 servlet 框架的示例並在你的最后嘗試。 如果部署成功，我們就會知道您這邊有問題。 否則，我們可能不得不在此處提交 Cloud Run 在 Java Servlet 應用程序中表現不佳的錯誤。
