Experiment with cookiecutter and docker to create a toyapp

toyapp

Abstract

Experiment with cookiecutter and docker to create a robust python tool that can be run directly in a container.

This toy project introduces the following concepts:

• Creating python packages from a cookiecutter template

• Basic elements of simple python package, including setuptools, entry points, and testing

• Adding a simple command line interface thanks to click

• Using docker to containerize the application

The toy application takes two numbers and a mathemtical operation and returns the result

Quickstart

Install the package with pip.

$ mkdir demo
$ cd demo
$ git clone https://github.com/ian1roberts/toyapp.git
$ cd toyapp
$ pip install .

Try out the command line interface

$ toyapp 1 2 "+"

Note that the operators must be quoted to avoid shell expansion.

Check out the help

$ toyapp --help

Usage: toyapp [OPTIONS] NUM1 NUM2 [OPERATION]

Perform simple arithmetic operations given two numbers and an operator.

If operator is ommited, the default is addition. To prevent * being
interpreted as a wildcard, use quotes around the operator.

--quiet, -q: Don't print the leading message, just return the result.
num1: float - The first number
num2: float - The second number
operation: str -The operation to perform on the two numbers

Evaluates the expression num1 operation num2 and prints the result.

Options:
    -q, --quiet  Don't print the result
    --help       Show this message and exit.

Features

The repository includes a Makefiile and Dockerfile to build and run the application in a container.

To build the container, run make build.

You can also pull the image from dockerhub with docker pull ian1roberts/toyapp:latest
