How to run Python script on Docker

First create a specific project directory for your docker image. For example:

mkdir /home/pi/Desktop/teasr/capturing

Copy the dockerfile and script there and change the current context to this directory

cp /home/pi/Desktop/teasr/capturing.py /home/pi/Desktop/teasr/dockerfile /home/pi/Desktop/teasr/capturing/

cd /home/pi/Desktop/teasr/capturing

This is best practice because the first thing docker-engine does when building is to read the entire current context.

Next we'll take a look at your Dockerfile. It should now look like this:

The next thing you need to do is to build it with a smart name, the use of dots is generally discouraged.

docker build -t pulkit/capturing:1.0 .

Next is to run the image like you did.

docker run -ti --name capturing pulkit/capturing:1.0

The script is now executed inside the container and may exit when finished.

Note: The first line in the script needs to be #! /usr/bin/env python .
