在上部署停靠映像

Question

我正在尝试部署一个Java套接字应用程序，该应用程序将通过TCP在某些端口上为传入的请求提供服务。映像构建良好，容器在本地运行。

但是，当部署到GCR时，它会引发以下错误

{
  "textPayload": "terminated: Application failed to start: Failed to create init process: failed to load /usr/lib/jvm/java-17-openjdk//bin/java: exec format error",
  "insertId": "631891ef0005eae9ece915df",
  "resource": {
    "type": "cloud_run_revision",
    "labels": {
      "project_id": "cumulus-0",
      "service_name": "cumulus",
      "revision_name": "cumulus-00001-hib",
      "location": "asia-south1",
      "configuration_name": "cumulus"
    }
  },
  "timestamp": "2022-09-07T12:43:27.387764458Z",
  "severity": "ERROR",
  "labels": {
    "instanceId": "00c527f6d4880e8a5a96fbdadc4536870f1e55a884c529efc6f860386bb3766d594380d65a657a35adebed119b05e2007cbef26928db216236f1641e97b306"
  },
  "logName": "projects/cumulus-0/logs/run.googleapis.com%2Fvarlog%2Fsystem",
  "receiveTimestamp": "2022-09-07T12:43:27.390641080Z"
}

特别是- terminated: Application failed to start: Failed to create init process: failed to load /usr/lib/jvm/java-17-openjdk//bin/java: exec format error

这是在不支持jvm的平台运行时发生的。但它在一个码头集装箱里。我不知道这是怎么回事。

这是我的Dockerfile

FROM alpine:latest
RUN apk update && \
    apk add openjdk17-jre=17.0.4.1_p1-r0

ENV JAVA_HOME=/usr/lib/jvm/java-17-openjdk

LABEL in.rainycloud.cumulus="hi@shantanubanerjee.com"

COPY build/libs/cumulus*.jar /usr/lib/

CMD ["/usr/lib/jvm/java-17-openjdk/bin/java", "-jar", "/usr/lib/cumulus-v0.1.jar", "in.rainycloud.cumulus.Main"]

EXPOSE 33333/tcp

Answer 1

首先，这条路似乎很可疑。为什么必须提供完整的java bin路径。如果您的构建依赖于其他需要c的库，那么请使用完整的jdk进行尝试。

还有，检查这段代码。它为您的服务器提供了起点。

# java -jar /usr/local/runme/app.jar
ENTRYPOINT ["java","-jar","app.jar"]
