Adding Ben Breard as this will be interesting to him.

Hi all
You may have seen recently that a few of us have started to maintain
some up-to-the-minute Node.js builder images for Docker and Openshift
[1]. At the moment, we have up to date images for Node 4,5,6 and 7.
However, these are all running on CentOS.
Recently, based on an email thread in @microservices, I started
looking into the image sizes for what we are producing, and was pretty
amazed to see ours at about 485MB. Not to be dissuaded, I decided that
I would see what effort was required to create Node.js 4,5,6 and 7
builder images on rhel7-atomic. Without too much effort, I managed to
create images based on this that were much smaller - about 140MB.
Great news!
However, this led me to a couple of questions that I would like to put
forward for discussion, and ultimately follow up with one or more
issues in https://issues.jboss.org/projects/NODE.
Based on the evidence I have seen, there is a lot of interest in a
smaller footprint for base/builder images. A rhel7-atomic builder
image (not specific to Node.js) that could be further added to by
projects like ours, would be very useful. A base builder image
currently exists for RHEL, Fedora and CentOS. These base images make
downstream projects such as ours much easier to implement because all
of the OpenShift specific bits are already taken care of (e.g.
STI_SCRIPTS_URL, etc).
I was wondering if there is any current effort to produce a similar
base image for rhel7-atomic. If not, is this the kind of activity that
would be left to the community, or are there plans in the works within
Red Hat to make this happen?
I also think that, in addition to the current OpenShift offerings for
Node.js on RHEL and CentOS, we should be providing a larger matrix of
options. Is there any reason not to pursue community versions of
Node.js builder images for the following combination of OS/Node?
RHEL -> Node 4, 5, 6, 7
rhel7-atomic -> Node 4, 5, 6, 7
Fedora -> Node 4, 5, 6, 7
CentOS -> Node 4, 5, 6, 7
I understand that SCL-provided, supported images for RHEL already
exist for Node.js v4.x and soon to be Node.js v6.x. As you probably
know, some of us are actively working towards a solution that would
allow these supported images to achieve greater turnaround time, and
maintain version parity with all current Node.js releases.
Would the addition of community provided rhel7-atomic, fedora and
perhaps even rhel images be welcomed?
