Flask Boilerplate

This repository is a collection of everything needed to get off the ground with Flask.

Get Going Quickly

To get going with this repo and get developing I recommend:

1 - create your own github account

2 - fork this repo (optional but means you can store any changes you make)

3 - add the prefix gitpod.io/# to this repos URL to get developing (remember to use your forked repo if you completed that step)

Tools Used

• Flask - python web framework that provides functions to make developing a web application easier.
• Github - source control and storing code somewhere accessible.
• Anaconda - python framework used to define a specific set of packages and dependencies to make the apps environment.
• Docker - containerises software needed for creating a development environment and packages up the app.
• Github Actions - used to complete repetitive tasks such as building containers and deploying the app.
• Gitpod - allows quick development without needing to install anything locally.
• Heroku - platform for deploying the app.

Nuts and Bolts

Each aspect of the development and deployment cycle is in this repo, these include:

• src - the source code directory. This has a few snippets of code for simple Flask services (including templates using Jinja2)
• .github - the Continuous Integration (CI) needed to build a gitpod environment for development and build and deploy this app! (notice the .secret parameters needed so I'm not sharing login details)
• Dockerfile - everything needed to spin up the Anaconda environment and containerise the app for deployment.
• environment.yaml - all the packages needed to make the right Anaconda environment ANYWHERE.
• docker-compose.yaml - a nice little tool to make local development easier. Just run docker-compose up -d to spin up the app defined in the Dockerfile locally.
• .gitignore - a list of everything you don't want in version control.
• .gitpod and .gitpod.yml - all the config and setup needed to allow development using Gitpod.
