docker image directory does not exist during build

I'm building a simple image from a Dockerfile: (note, pm3 is the name of the folder this Dockerfile lives in)

pm3

FROM continuumio/miniconda3
MINTAINER Jordan Miller
ENV PORT=5000
COPY . /opt/repos/
WORKDIR /opt/repos/pm3/

RUN ls -la

RUN python /opt/repos/pm3/lib/acquire_requirements.py

EXPOSE $PORT
ENTRYPOINT ["python","/opt/repos/pm3/src/web/api.py"]


I use docker build -f Dockerfile -t jm/pm3 . to build it. Now I thought this was working great last week, but I made some changes and it broke. so I ran docker system prune to clean everything out. But that didn't fix it so I think it's something wrong with the code.

docker build -f Dockerfile -t jm/pm3 .

docker system prune

At any rate, here's the error I get:

Step 7/9 : RUN python /opt/repos/pm3/lib/acquire_requirements.py
---> Running in f842a282a6a0
Invalid requirement: '/opt/repos/pm3/lib/acquire_requirements.py'
File '/opt/repos/pm3/lib/acquire_requirements.py' does not exist.


But it really is there, in my windows machine there's a lib folder in the pm3 folder and there is a acquire_requirements.py in the lib folder. should I not include the entire path to it on the linux box or something?

lib

pm3

acquire_requirements.py

lib

I included that line RUN ls -la after it gave me the error because I wanted to see if it copied over the folder correctly. but the output of that didn't show me anything had copied over, it showed an empty file. so I don't understand really what's going on. If the working directory really is /opt/repos/pm3 then shouldn't I see src when I run ls?

RUN ls -la

/opt/repos/pm3

src

ls

I'm hoping there's something obvious about linux or docker that I'm missing here. any ideas?

.dockerignore

docker build

pm3

so I discovered by creating an image without the RUN python /opt/repos/pm3/lib/acquire_requirements.py that it doens't create a folder after the /opt/repos/ called pm3 like my root directory of the Dockerfile is in.

RUN python /opt/repos/pm3/lib/acquire_requirements.py

/opt/repos/

pm3

So I had to add that in manually to the command:

COPY . /opt/repos/ -> COPY . /opt/repos/pm3/

COPY . /opt/repos/

COPY . /opt/repos/pm3/
