What is docker-hello-world?

crccheck/hello-world is a minimal Docker image that runs a tiny HTTP web server on port 8000. It is intended for developers who need a fast-starting container that speaks HTTP for testing scenarios such as reverse proxy configuration, load balancer checks, or CI pipelines. The image is under 2 MB and starts in under a second. It responds to GET requests with a simple "Hello World" page and returns 501 for unsupported methods. There is no authentication, database, or configuration — it is a single-purpose test utility. The project is published on Docker Hub as crccheck/hello-world and the source is on GitHub.
