rahulkaddi7/AWS-CICD ? reverse-engineered prompt

Build me a simple Python project that shows a full AWS CI/CD flow for a small Dagster app. I want it to run locally with Docker Compose, build into a container, and include the files needed to deploy it through AWS using CodeBuild and CodeDeploy style setup. Please make the project easy to understand, with a minimal Dagster example, clear startup instructions, and the right config files so someone can clone it, run it locally, then push it through a basic deployment pipeline.

If anything depends on current AWS or Dagster setup details, look up the latest docs online and keep it practical. I also want the repo to feel complete, so include sensible defaults, a working Dockerfile, and the build and deploy configs wired together cleanly. If you can, add a short note in the README explaining how the local run and AWS deployment pieces fit together.
