Solution 1
You can use python base image
FROM python:2.7
This base image with have python pre-configured and you don't need to install python seperately. Hope it helps.
Here is the list of available image
For quick reference please check https://blog.realkinetic.com/building-minimal-docker-containers-for-python-applications-37d0272c52f3
Solution 2
You can use "FROM python:2.7" , the base image.
FROM python:2.7
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD [ "python", "./your-daemon-or-script.py" ]
(documentation link)please find some examples here

I have node app and in one use case I am calling python script from node using
python-shell
. I am trying to setup this app on docker and my Dockerfile looks something like thisFROM debian:latest # replace shell with bash so we can source files RUN rm /bin/sh && ln -s /bin/bash /bin/sh # update the repository sources list # and install dependencies RUN apt-get update \ && apt-get install -y curl \ && apt-get -y autoclean # nvm environment variables ENV NVM_DIR /usr/local/nvm ENV NODE_VERSION 10.15.3 # install nvm # https://github.com/creationix/nvm#install-script RUN curl --silent -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.2/install.sh | bash # install node and npm RUN source $NVM_DIR/nvm.sh \ && nvm install $NODE_VERSION \ && nvm alias default $NODE_VERSION \ && nvm use default # add node and npm to path so the commands are available ENV NODE_PATH $NVM_DIR/v$NODE_VERSION/lib/node_modules ENV PATH $NVM_DIR/versions/node/v$NODE_VERSION/bin:$PATH # confirm installation RUN node -v RUN npm -v RUN apt-get -y install python2.7 COPY package.json . RUN npm install COPY . . CMD ["npm","run","start"]
after building and running this container when I try to invoke use case where python script gets called from node I am getting this error.
