This is a simple image that just gives a response on port 8000. Use this to test your web orchestration. It's small enough to fit on two floppy disks:
$ docker images | grep hell
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
crccheck/hello-world latest 3fb806978748 7 minutes ago 2.434 MB
$ docker run -d --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
Hello World
...
# Every request returns the same thing
$ curl -X POST localhost/super/secret
Hello World
...
# Does not send actual HTTP responses (this should probably change so this can
# be used with load balancers)
$ curl --write-out %{http_code} --silent --output /dev/null localhost
