I am trying to run a Kafka Streams application in kubernetes. When I launch the pod I get the following exception:

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

Previously I have tried launching kafka and kafka-streams-app using docker containers and they worked perfectly fine. This is the first time I am trying with Kubernetes.

This is my 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"]

What can I do to get past this issue? Kindly help me out.

EDIT:

/ # ldd /usr/bin/java 
    /lib/ld-musl-x86_64.so.1 (0x7f03f279a000)
Error loading shared library libjli.so: No such file or directory (needed by /usr/bin/java)

In my case, install the missing libc6-compat didn't work. Application still throw java.lang.UnsatisfiedLinkError.

Then I find in the docker, /lib64/ld-linux-x86-64.so.2 exist and is a link to /lib/libc.musl-x86_64.so.1, but /lib only contains ld-musl-x86_64.so.1, not ld-linux-x86-64.so.2.

So I add a file named ld-linux-x86-64.so.2 linked to ld-musl-x86_64.so.1 in /lib dir and solve the problem.

Dockerfile I use:

FROM openjdk:8-jre-alpine
COPY entrypoint.sh /entrypoint.sh
RUN apk update && \
  apk add --no-cache libc6-compat && \
  ln -s /lib/libc.musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2 && \
  mkdir /app && \
  chmod a+x /entrypoint.sh
COPY build/libs/*.jar /app
ENTRYPOINT ["/entrypoint.sh"]

In conclusion:

RUN apk update && apk add --no-cache libc6-compat
ln -s /lib/libc.musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2
