FileNotFound exception when deploying application to Azure

So, I have a spring boot application, and it in part takes in a file and reads the contents. It runs perfectly locally, but when I put it on a Docker image and deploy to azure, I get a file not found error. Here is my dockerfile:

FROM [place]
VOLUME /tmp
ARG jarFileName
RUN mkdir /app 
COPY $jarFileName /app/app.jar
RUN sh -c 'touch /app/app.jar'
ENV JAVA_OPTS=""
COPY startup.sh /app/startup.sh
RUN ["chmod", "+x", "/app/startup.sh"]
CMD ["startup.sh"]

With the Dockerfile you posted, I think there are several places need to pay attention to.

The first is that the line COPY $jarFileName /app/app.jar will get the error if you do not pass the variable jarFileName in the command docker run.

The second is that you should check the current directory for the line COPY startup.sh /app/startup.sh if there is the file startup.sh.

The last is that the line CMD ["startup.sh"], I think you should change it into CMD ["./startup.sh"]. Usually, we execute a shell script using the command sh script.sh or ./script.sh if the script has the permission 'x'.
