Deploying an ASP.NET Core App with MySQL on Fly.io

Deploying a containerized ASP.NET Core MVC app with a MySQL database can seem daunting, but Fly.io makes it surprisingly simple. If you've already launched your app and need to overwrite your existing deployment, follow this guide to smoothly redeploy your updated application.

Install Fly.io CLI

curl -L https://fly.io/install.sh | sh

Authenticate with Fly.io

flyctl auth login

Deploy the Updated App

Ensure you're in the correct project directory where fly.toml is located:

cd /Users/katysolovewicz/Projects/epicodus/c#/CreatureTeacher.Solution
flyctl deploy

Apply Database Migrations (If Needed)

If your database schema has changed, apply migrations to ensure MySQL is up to date.

flyctl ssh console -a <your-app-name>
dotnet ef database update
exit

Restart the App (If Needed)

flyctl apps restart <your-app-name>

Fly.io provides a streamlined way to deploy and update ASP.NET Core MVC applications with MySQL, making container-based hosting simple and scalable. By following this workflow, you can ensure a seamless redeployment whenever your app needs updates.

Happy coding! 🚀
