From 7517d88f12cbb1faac5c2d583ae2799745518d0c Mon Sep 17 00:00:00 2001 From: Bruno Wolff III Date: Oct 15 2014 11:26:10 +0000 Subject: Revert "Dropping bigdata cloud spin from f21" This reverts commit 1d4a252ed6495f3d6abf95ec4350efbc8100c631. We need to go back to the broken merge. --- diff --git a/fedora-cloud-bigdata.ks b/fedora-cloud-bigdata.ks new file mode 100644 index 0000000..1a9ef6a --- /dev/null +++ b/fedora-cloud-bigdata.ks @@ -0,0 +1,226 @@ +# This is a Fedora 21 spin designed based on the Fedora Cloud Base Image +# but tailored specifically for Big Data processing out-of-the-box. +# Primarily, it builds on that image but adds extra packages, but over +# time may have additional focus. +# +# It's configured with cloud-init so it will take advantage of +# ec2-compatible metadata services for provisioning ssh keys.
