Docker build: runnable is in parent folder

Question

I have multiple Dockerfiles in a different folder but the source for all the dockers is the same.

FROM openjdk:11.0.5-stretch

COPY my.zip /home/my.zip

RUN unzip /home/target.zip -d /home/ && rm -f /home/target.zip

ENTRYPOINT ["java", "-jar", "/home/my/{a.jar, b.jar, ...}"

Either one of the jar will be used in one Docker file. I have a python script which runs all the docker build commands, whenever I update something in code and recompile, I have to copy my.zip in almost 20 folders. Is it possible we ADD the file from the root folder as

ADD ../my.zip /home/my.zip

Is it possible?

sure using `../` is fine, did you try? – Lawrence Cherone Nov 25 '19 at 05:19 — Lawrence Cherone, Nov 25 '19 at 05:19
Yes, I did but in vain. – Cool Java guy מוחמד Nov 25 '19 at 10:40 — Cool Java guy מוחמד, Nov 25 '19 at 10:40

Try building docker images from the parent directory with "-f" flag:

 docker build -t <your_tag> -f dirA/dirB/Dockerfile .

I already know this but I do not want to change my python script implementation. I want to Add ../my.zip file in image. – Cool Java guy מוחמד Nov 25 '19 at 10:39
