Detect Docker in any GitHub repo

Docker packages applications and their dependencies into containers, defined by a Dockerfile and often orchestrated with Docker Compose.

Why show Docker on your README

A Docker signal tells users the project can be run with a single `docker compose up`, often the fastest way to try it.

How Docker is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags Docker when it finds any of these:

  • Files or folders: /^Dockerfile\./, Dockerfile, docker-compose.yml, docker-compose.yaml, compose.yml, compose.yaml, .dockerignore

Docker README badge

A static badge you can paste anywhere in Markdown:

![Docker](https://img.shields.io/badge/Docker-2496ED?style=for-the-badge&logo=docker&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so Docker (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
