el323 :
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.

raspy :
Error message states that *libsnappyjava.so cannot find ld-linux-x86-64.so.2. This is a glibc dynamic loader, while Alpine image doesn't run with glibc. You may try to get it running by installing libc6-compat package in your Dockerfile, e.g.:
RUN apk update && apk add --no-cache libc6-compat
