What is an ephemeral environment?

It is a temporary, isolated deployment of your application that exists only for the duration of a pull request, allowing developers to test changes in a live environment before merging.

How does the system handle networking and public access?

It utilizes Cloudflare Tunnels to securely expose the application running on port 80 inside the EC2 instance to a public URL posted as a comment on the PR.

What configuration is required in my repository?

You need a docker-compose.yml file in your root directory that exposes your main application service on port 80 and the GitHub App installed on your repo.

Does this skill require an AWS account?

Yes, the underlying system is designed to run Docker Compose services on AWS EC2 instances for each preview environment.

Will the environments be deleted automatically?

Yes, the system listens for GitHub webhooks and automatically terminates the EC2 instance and cleans up resources as soon as the pull request is closed or merged.
