Setting up Flask

Today’s goal is to set up your first working Flask application!

Virtual Environments and venv

The term environment is overloaded in computing.

Our goal in this lesson is to first create a virtual environment on our local machine based on something in our repository, then deploy that same repository to the place we are mirroring.

Mirroring an Environment

Set up a Flask Development Environment

Clone a repository:

git clone https://github.iu.edu/i211su2024/REPO_NAME.git
cd REPO_NAME

Create a venv environment and install dependencies:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Check whether flask works correctly:

python -m flask --version

Deploying an Application

Heads up! There’s a typo in the instructions on your GitHub repositories. Use these commands when setting up instead:

As always, swap USERNAME with your IU username:

ssh USERNAME@silo.luddy.indiana.edu

git clone https://github.iu.edu/i211su2024/USERNAME-i211-project.git ~/cgi-pub/i211-project

git clone https://github.iu.edu/i211su2024/USERNAME-i211-lecture.git ~/cgi-pub/i211-lecture
