How to run python script on docker

First create a specific project directory for the 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 read the entire current context.

Next we will look at your dockerfile. It should now look like this:

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

docker build -t pulkit/capturing:1.0 .

The next step is to run the image as you did.

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

The script now executes inside the container and may exit when completed.

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