Hello World

This is a simple Docker image that just gives http responses on port 8000. It's small enough to fit on one floppy disk:

$ docker images | grep hell
REPOSITORY               TAG       IMAGE ID        CREATED          VIRTUAL SIZE
crccheck/hello-world     latest    2b28c6ad8d1b    4 months ago     1.2MB

I made this initially because there were lots of scenarios where I wanted a Docker container that speaks HTTP, but every guide used images that took seconds to download. Armed with a tiny Docker image, I could test things in a fresh environment in under a second. I like faster feedback loops.

THANK YOU to the surprisingly large number of contributors that have made this better for everyone over the years.

Sample Usage

Starting a web server on port 80

$ docker run -d --rm --name web-test -p 80:8000 crccheck/hello-world

You can now interact with this as if it were a dumb web server:

$ curl localhost
<xmp>
Hello World
...snip...

$ curl -I localhost
HTTP/1.0 200 OK

$ curl -X POST localhost/super/secret
<HTML><HEAD><TITLE>501 Not Implemented</TITLE></HEAD>
...snip...

$ curl --write-out %{http_code} --silent --output /dev/null localhost
200
