Armed with a tiny Docker image, I could test things in a\nfresh environment in under a second. I like faster feedback loops.\n\n**THANK YOU** to the surprisingly large number of contributors that have made\nthis better for everyone over the years.\n\n## Sample Usage\n\n### Starting a web server on port 80\n\n```bash\n$ docker run -d --rm --name web-test -p 80:8000 crccheck/hello-world\n```\n\nYou can now interact with this as if it were a dumb web server:\n\n```\n$ curl localhost\n\nHello World\n...snip...\n```\n\n```\n$ curl -I localhost\nHTTP/1.0 200 OK\n```\n\n```\n$ curl -X POST localhost/super/secret\n<HTML><HEAD><TITLE>501 Not Implemented</TITLE></HEAD>\n...snip...\n```\n\n```\n$ curl --write-out %{http_code} --silent --output /dev/null localhost\n200\n```\n" }, { "path": "index.html", "content": "<pre>\nHello World\n\n\n ## .\n ## ## ## ==\n ## ## ## ## ## ===\n /\"\"\"\"\"\"\"\"\"\"\"\"\"\"\"\"\\___/ ===\n ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ / ===- ~~~\n \\______ o _,/\n \\ \\ _,'\n `'--.._\\..--''\n</pre>\n" } ]
