In order to support e.g. bare metal and other user-provisioned infrastructure platforms, let's add a high level command to download the "bootimages" (qemu qcow2, bare metal UEFI, VMWare vmdk, and for that matter the AWS VMDK).

Something like:

$ openshift-install download-bootimage --platform=metal-uefi
Downloading redhat-coreos-metal-uefi-4.72.raw ...done.

@cgwalter,

it sounds good !
I think the same for libvirt use with bridge

I do not think that the the installer should be downloading the bootimages

  • how is the installer supposed tied the recommended platform flag to the set of images required. for example for metal some people will use the iso, while some want the iso (for pxe assets) and raw image for installation.
  • recommended platform flag is already used by installer and creates confusion...
  • The installer needs to move to release image for all source of truth, the intermediate direction is pulling the release image pkg/rhcos/release: Extract RHCOS build from release image #1286. But in the long term it would be nice to move all the image information onto the bootstrap node and installer only chooses the release image.

I think the simplest is:

openshift-install download-bootimage --platform=metal

which would do all of the metal stuff. The ISO is tiny, and anyone installing on metal surely has enough bandwidth to grab both metal-uefi and metal-bios.

I've taken a stab at something similar in #1529, if folks want to take a look.

Today RHCOS is available here: https://mirror.openshift.com/pub/openshift-v4/dependencies/rhcos/4.1/

However, it still must be downloaded manually.

If you want something other than that, today you can find the download URL used by the installer in git:

$ rg releases-art
data/data/rhcos.json
49:    "baseURI": "https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/ootpa/410.8.20190508.1/",

Ideally this would be an implementation detail of the installer, but in the short term that URL isn't going away.

@cgwalters
version: Output RHEL CoreOS bootimage version
d3cab5e 
There are a lot of reasons to want to know the RHCOS bootimage version
associated with an installer - the installer pins it today, but doesn't
make the information easy to find particularly in a CI/development
environment.

This is a very small step towards something like:

We can't easily right now do the "download" part without having an online service which maps from e.g. ostree-version to OpenShift versions.

Maybe...what we should do for this is treat RHCOS the same as the release image - and particularly for official installer releases we binary patch the binary so that it refers to https://mirror.openshift.com/pub/openshift-v4/dependencies/rhcos/ or so.

@abhinavdahiya what do we need to do to progress this as I see this as a huge win for our user experience in a few IPI use cases and mainly in all UPI use cases (as it helps simplify much of the complicated and cumbersome documentation points we have now).

Another appoach here is to expand on the "redirector service" model that we already use on the RHCOS side. A team like SD would run a dynamic service mirror.openshift.com/pub/openshift-v4/dependencies/rhcos?sha256=ff088ec361f94258a4cd9400e8483b3fc14be7e205e645b372003e77de7ec3a.

To avoid duplication, the existing "static" content would just become redirects to the dynamic one which fetched by sha256sum.

To say this another way, there would be a unified way to fetch bootimage binaries that is exactly the same between dev and release - which is part of achieving the important goal of making releases just like "git tag" and not a special series of steps.

@cgwalters
Add new rhcos-metadata command
2a324b0 
Today the installer pins RHCOS, and that's not likely
to change.  The embedded version isn't easy to know in
pre-release/development scenarios.

Further, the way we do releases via CI, we don't know
what the "re-branded OpenShift version" (e.g. 4.1.0)
will be until it's released.

For other things like the AMIs, today the documentation
writers copy them into the docs manually.

Since the installer is the canonical source of this data,
let's make it easy to extract.

We're not documenting this much yet, but having this
data easily available is going to be extremely helpful
for the variety of cases mentioned above and allow
other teams to have a canonical way to get it.
