while I am using docker desktop, windows container, getting below messege.

F:\Work\Workspace\IntellejIdea\kubernetes-for-java-developers\app>docker

docker: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"./myjre/bin/java\": stat ./myjre/bin/java: no such file

My operating system is windows 10 pro.

Dockerfile.jre

FROM debian:9-slim

COPY target/app.war /root
COPY myjre /root/myjre

EXPOSE 8080 5005
WORKDIR /root
ENV _JAVA_OPTIONS '-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005'
CMD ["./myjre/bin/java", "-jar", "app.war"]

As I am new on this docker/kubernetes technology, not sure where to start debugging, or the issues.

help appreciated!!
