This sample is intended to provide a basic understanding of how to get started with Flask on Defang. it is not intended for production use. If you need something production ready, you should use a managed database like Postgres or MySQL.

Essential Setup Files

1. A Dockerfile.
2. A compose file to define and run multi-container Docker applications (this is how Defang identifies services to be deployed).
3. A .dockerignore to ignore files that are not needed in the Docker image or will be generated during the build process.

Prerequisite

1. Download Defang CLI
2. If you are using Defang BYOC, make sure you have properly authenticated your AWS account (optional)

A Step-by-Step Guide

1. Open the terminal and type defang login
2. Type defang compose up in the CLI
3. Your app should be up and running with Defang in minutes!
