Docker-compose EACCESS error when spawning executable - node.js

Question

I have a Dockerfile where I bring in some files and chmod some stuff. it's a node server that spawns an executable file.
FROM ubuntu:16.04
RUN apt-get update && apt-get install -y --no-install-recommends curl sudo
RUN curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
RUN apt-get install -y nodejs && \
apt-get install --yes build-essential
RUN apt-get install --yes npm
#VOLUME "/usr/local/app"
# Set up C++ dev env
RUN apt-get update && \
apt-get dist-upgrade -y && \
apt-get install gcc-multilib g++-multilib cmake wget -y && \
apt-get clean autoclean && \
apt-get autoremove -y
#wget -O /tmp/conan.deb -L https://github.com/conan-io/conan/releases/download/0.25.1/conan-ubuntu-64_0_25_1.deb && \
#dpkg -i /tmp/conan.deb
#ADD ./scripts/cmake-build.sh /build.sh
#RUN chmod +x /build.sh
#RUN /build.sh
RUN curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
RUN apt-get install -y nodejs sudo
RUN mkdir -p /usr/local/app
WORKDIR /usr/local/app
COPY package.json /usr/local/app
RUN ["npm", "install"]
COPY . .
RUN echo "/usr/local/app/dm" > /etc/ld.so.conf.d/mythrift.conf
RUN echo "/usr/lib/x86_64-linux-gnu" >> /etc/ld.so.conf.d/mythrift.conf
RUN echo "/usr/local/lib64" >> /etc/ld.so.conf.d/mythrift.conf
RUN ldconfig
EXPOSE 9090
RUN chmod +x dm/dm3
RUN ldd dm/dm3
RUN ["chmod", "+x", "dm/dm3"]
RUN ["chmod", "777", "policy"]
RUN ls -al .
CMD ["nodejs", "app.js"]
it works all fine but when I use docker-compose for the purpose of having an autoreload dev enviornment in docker, I get an EACCES error when spawning the executable process.
version: '3'
services:
web:
build: .
command: npm run start
volumes:
- .:/usr/local/app/
- /usr/app/node_modules
ports:
- "3000:3000"
I'm using nodemon to restart the server on changes, hence the volumes in the compose. woulds love to get that workflow up again.

I think that you problem is how you wrote the docker-compose.yml file.
I think that the line command doesn't necessary because you
especified how start the program in Dockerfile.
Could you try to run this lines?
version: '3'
services:
web:
build:
context: ./
dockerfile: Dockerfile
volumes:
- .:/usr/local/app/
- /usr/app/node_modules
ports:
- "3000:3000"
Otherwise, I think that the volumes property doesn't share /usr/app/node_modules. And I think that this is bad practice. You can run "npm install" in your Dockerfile
I hope that you could understand me =)
