Migrating a Flask Application to Chainguard

This repository shows a migration to Chainguard Containers + Libraries in stages.

We start with a simple containerized Flask application based on a default Python image, migrate it to Chainguard Containers, then switch to pull additional dependencies from Chainguard Libraries.

To clone and fetch/pull all branches:

git clone git@github.com:chainguard-dev/cg-images-python-migration.git
cd cg-images-python-migration
git branch -r | grep -v '\->' | sed "s,\x1B\[[0-9;]*[a-zA-Z],,g" | while read remote; do git branch --track "${remote#origin/}" "$remote"; done
git fetch --all
git pull --all

The below branches show different stages of project development:

• Pre-migration Flask app
• Flask application and Dockerfile only
• Docker Compose with Flask application and nginx
