I have an application that takes voice input from microphone, performs speech recognition and plays certain music files based on the cue words recognized. This application is in Python and implements a couple of python modules like PyAudio, Playsound and Websocket-client. I am trying to build a Docker image of this application.
I have created a Dockerfile with below contents:
FROM ubuntu ADD . /app FROM python:3 ADD transcribe.py / ADD speech.cfg / ADD setup.cfg / ADD setup.py / RUN apt-get update RUN apt-get --assume-yes install libasound-dev portaudio19-dev libportaudio2 libportaudiocpp0 RUN pip3 install pyaudio RUN pip3 install websocket-client RUN pip3 install playsound CMD [ "python3", "./transcribe.py" ] When trying to build it, I get a successful build response as below:

While its is possible to resolve similar issues in Virtual Machines, I am not sure if there is a simple way to resolve the same in docker containers.
