Hardy, Lala and the rest of the ADB team are going to investigate this
over the next few weeks (whether we can replace the ADB infra with
minishift).
For the product version it must be based on something that we
productise (which currently is RHEL or Atomic AFAIK) - doing it on top
of something like Alpine is not an option.
You can see what it's built from at
https://hub.docker.com/r/boot2docker/boot2docker/~/dockerfile/ . Don't
worry about the FROM debian:jessie - that's just to create the builder
image. You can see the minimal stuff it's actually installing in the
final ISO.
I would also worry about having a radically different upstream from
the product version, as I think this can cause bugs, but I'll leave
this one to the team to figure out :-)
I've also asked Ian a few times if we can try to build smaller images
- something to keep trying for ;-)
I don't see why we couldn't have the equivalent of boot2docker.iso
image that minikube uses: basically a kernel & docker.... that's it.
Sure we can use a RHEL/CentOS kernel, right? Just please not the whole
RHEL install ;)
Agreed. I think Pete and I are just saying that we need to make an effort
to fix the actual problem (we don't have a small ISO for RHEL/CentOS that
represents our strengths in containers), and that we should also be taking
those steps in parallel.
Exactly. I also still don't understand why we don't ship Atomic Host
as the default OS in the container runtime portion of the CDK - this
seems like an obvious thing to do .
I think we should incorporate container runtime portion of Atomic host
in CDK. It makes more sense in current context as we are running
OpenShift and Kubernetes as containers. Just to add bit of history ,
when we started CDK 2.0 we were not sure if using Atomic host is a good
idea as the file system of Atomic host is read-only except /etc and /var.
Also we need to take decision around if we want to keep the Kubernetes
single node setup relevant in CDK context as my recent understanding is
that we are encouraging users to use OpenShift for Kubernetes specific
usage.
Thanks,
Lala
