docker-python-helloworld

A Python dockerized hello world app This repo aims at showing how simple it can be to build a Docker container running a Python (very simple) app. Once you understand how this simple example works, it's easy to apply it to bigger apps.

Steps to run directly the python code

It's highly recommended to install the (empty) dependencies in a virtual environment.

• Creating the virtual environment:

virtualenv venv

• Activating the virtual environment:

source venv/bin/activate

• Installing dependencies:

pip install -r requirements.txt

• Running the code:

python main.py

Steps to run the python code within a Docker container

• Build the image:

docker build -t docker-python-helloworld:lastest

• Run the container:

docker run docker-python-helloworld:latest
