"It worked when I ran it locally" stops being good enough the moment a second person opens a pull request.
Part 6 of the MiniStack series wires MiniStack into a CI pipeline as a throwaway AWS stand-in, so every push gets checked the same way, automatically:
Why a plan on your laptop isn't enough once there's a team
A complete GitHub Actions workflow with MiniStack running as a service container
Pointing Terraform at it with environment variables instead of checked-in config
What a green run actually proves, and what still needs a real, locked-down AWS account
It starts in seconds, needs no AWS credentials, and costs nothing no matter how many times a day it runs. Your CI bill will be the least interesting part of the job.
