I am trying to deploy and run the java application in kubernetes POD for which I am getting below error. But when I run it as a docker container it is running fine.

Here is the Dockerfile -

FROM openjdk:8-jre-alpine
ENV artifact mysessionmanager-1.0.0-SNAPSHOT.jar
WORKDIR /root/apps
COPY . /root/apps
EXPOSE 8080
ENTRYPOINT ["sh", "-c"]
CMD ["java -jar ${artifact}"]

docker build -t mysessionmanager .
docker tag mysessionmanager xxxx/mysessionmanager:v1
docker push xxxx/mysessionmanager
kubectl run mysessionmanager --image=xxxx/mysessionmanager:v1 --port=8080
kubectl expose deployment --type=NodePort --port=80 --target-port=8080 --name=mysessionmanager  

kubectl get deployments showing my deployment Available status as 0

kubectl get pods showing my POD's status as CrashLoopBackOff

kubectl get logs mysessionmanager-5654545f8-mvt5x shows nothing

kubectl describe pod mysessionmanager-5654545f8-mvt5x

Reason: CrashLoopBackOff
Last State: Terminated
Reason: ContainerCannotRun
Message: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"java -jar mysessionmanager-1.0.0-SNAPSHOT.jar\": executable file not found in $PATH": unknown

But when I directly run the docker image using below command it works fine.

docker run -it mysessionmanager

Appreciate any help. Thanks
