Geode docker image

[Udo Kohlmeyer]

Hi there,

I'm following the instructions to download the latest Geode docker image 
as  described.
https://cwiki.apache.org/confluence/display/GEODE/How+to+use+Geode+on+Docker
It complains that "nightly" is not tag it understands. Also when using 
the Docker UI (Kitematic), it tries to download "latest" and that does 
not seem to work either.

Any ideas?
