Question

我正在尝试在kubernetes中运行Kafka Streams应用程序。当启动Pod时，出现以下异常：

Exception in thread "streams-pipe-e19c2d9a-d403-4944-8d26-0ef27ed5c057-StreamThread-1"

以前，我曾尝试使用docker容器启动kafka和kafka-streams-app，它们运行得很好。这是我第一次尝试使用Kubernetes。

这是我的 DockerFile StreamsApp ：

FROM openjdk:8u151-jdk-alpine3.7

COPY /target/streams-examples-0.1.jar /streamsApp/

COPY /target/libs /streamsApp/libs

CMD ["java", "-jar", "/streamsApp/streams-examples-0.1.jar"]

我该怎么做才能克服这个问题？请帮我。

编辑：

/ # ldd /usr/bin/java

错误消息指出* libsnappyjava.so无法找到ld-
linux-x86-64.so.2。这是一个glibc动态加载程序，而Alpine映像无法与glibc一起运行。您可以尝试通过在Dockerfile中安装libc6-compat软件包来使其运行，例如：

RUN apk update && apk add --no-cache libc6-compat
