This is a submission for the GitHub Copilot CLI Challenge
What I Built
Dockergen, a CLI tool that generates Dockerfile/Containerfile templates in seconds. It started as a way to remove repetitive setup work for Node.js and Python projects. The MVP focuses on speed and correctness: an interactive generator and an auto-detection mode that inspects a project to pick sensible defaults.
Demo
Repo: https://github.com/frsfahd/dockergen
Quick demo:
dockergen generate
dockergen autogen
Both commands output a production-ready multi-stage Dockerfile with defaults tuned to the detected runtime.
generate is interactive: it asks you questions and uses your answers (or flags) to build the Dockerfile.
autogen is automatic: it inspects the current project (package.json, requirements, lockfiles, version files) to infer language/framework, ports, start/build commands, and then generates the Dockerfile with those defaults.
My Experience with GitHub Copilot CLI
Copilot CLI helped me iterate fast. I used it to scaffold the Cobra-based commands, design the generator template flow, and build a lightweight auto-detection module. It was especially helpful for wiring the CLI flags and keeping the implementation focused on MVP scope while still following best practices.
