Accessing static files in Spring boot docker container image

I’ve managed to create a docker image. And under the Docker Container files section I am able to see the directory as is.

Docker Container file-structure image

My working directory : "usr/local/bin/ClientApp"

Dockerfile:

FROM openjdk:11
EXPOSE 8080
WORKDIR /usr/local/bin/ClientApp
ADD . .
ADD target/ClientApp-0.0.1-SNAPSHOT.jar .
ENTRYPOINT ["java", "-jar", "ClientApp-0.0.1-SNAPSHOT.jar"]

    Thanks all, however, I managed to resolve the issue by providing the filepath as : "spring.cloud.gcp.credentials.location=classpath:/service-key.json" in application.properties.

    Try checking out the files inside the container yourself

    docker run --rm -it --entrypoint bash <docker-img>
