Create a nodejs container Docker based on ubuntu - node.js

Question

I used the official nodejs image to create a docker container that run a nodejs app.
But now I want to create the same docker but my own base on ubuntu:14.04 but it doesn't work
Dockerfile mynode
FROM ubuntu:14.04
RUN apt-get update -y
RUN apt-get upgrade -y
RUN apt-get install nodejs -y
RUN apt-get install nodejs-legacy -y
RUN apt-get install npm -y
RUN npm install -g nodemon
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY ./prj/package.json /usr/src/app/
RUN npm install
ADD ./prj /usr/src/app
EXPOSE 9977
# Run app using nodemon
CMD ["nodemon", "/usr/src/app/app.js"]
If I change the line from ubuntu:14.04 to node it works well.
But now if I use a docker-compose to build and run the container it doesn't work.
node:
restart: always
build: ./mynodeFolder
ports:
- "9977:9977"
I have the error :
Now if I use the image build with the mynode DockerFile and use docker run -it --rm myNewContainer bash and then start my app using nodemon it works perfectly !
So everything is well installed and packed within the my dockerimage, so why it doesn't work when build with the docker-compose
It works now when i use this DockerFile
# Set the base image to Ubuntu
FROM ubuntu:14.04
#FOR DEBUGGING
RUN apt-get update -y
RUN apt-get upgrade -y
RUN apt-get install nodejs -y
RUN apt-get install nodejs-legacy -y
RUN apt-get install npm -y
# Install nodemon
RUN npm install -g nodemon
# Provides cached layer for node_modules
RUN mkdir -p /usr/src/app
# Define working directory
WORKDIR /usr/src/app
ADD ./prj /usr/src/app
RUN npm install
# Expose port
EXPOSE 9977
# Run app using nodemon
CMD ["nodemon", "/usr/src/app/app.js"]

Here is the Dockerfile for the official node image:

If you go to http://imagelayers.io, you can see the combined Dockerfile for the image, including the buildpack-deps:jessie base image:
