Using Docker to Run Python Script

In this post, I will create a python container and run python script inside docker container and run python script directly through docker.

Pull and Start Docker Image

docker pull python

Start a python container

docker run -it -d --name mypython -p 8888:80 -v /data/www/python/:/usr/src/myapp/python bash

Explanation:

--name mypython container name

-p 8888:80 host port 8888 mapped to container port 80

-v /data/www/python/:/usr/src/myapp/ mapping directory, container directory /usr/src/myapp/ persistent to the host /data/www/python/ directory

Execute Python Script In Docker

Then write a hello.py file on the host machine, and then enter the container

docker exec -it mypython bash

Run Python program in the container

python /usr/src/myapp/hello.py

$ docker run -it -d --name python -p 82:80 -v /data/www/python/:/usr/src/myapp/ mypython bash
