<div dir="ltr">Hi all
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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!</div>
<div><br>
</div>
<div>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 <a href="https://issues.jboss.org/projects/NODE" target="_blank">https://issues.jboss.org/<wbr>projects/NODE</a>.</div>
<div><br>
</div>
<div>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).</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>RHEL -> Node 4, 5, 6, 7 </div>
<div>rhel7-atomic -> Node 4, 5, 6, 7</div>
<div>Fedora -> Node 4, 5, 6, 7</div>
<div>CentOS -> Node 4, 5, 6, 7</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Would the addition of community provided rhel7-atomic,
fedora and perhaps even rhel images be welcomed?</div>
