[CoreOS] Re: Fwd: How we can make CoreOS Image support AArch64?

[Jakub Cajka]

Yes coreos assembler should be in good shape to be build images for aarch64(and other
64-bit arches of Fedora). You can get unofficial images that I'm building from
https://fedorapeople.org/groups/fcos-images/ I would much appreciate any feedback and
testing there.

General issue for official non-x86_64 images/builds is the infrastructure and setting up
the pipeline(s).
1. For start we need to officially build the "Fedora" coreos-assembler container
for non-x86_64.
  * One option is that quay.io would start support more than x86_64 for container builds.
I see that as extremely unlikely.
  * Other are to enable builds of non-x86_64 layered images on the Fedora infrastructure
or moving build of the coreos-assembler image on to the FCOS pipeline.
    Both have really prerequisite of openshift cluster(s) for all respective arches(might
be short circuited by using bare-metal jenkins workers in case of FCOS pipeline, work on
PoC in progress). That has been blocked on the DC move(that should be hopefully concluded
now) and on lack of the personnel on the infra side that would maintain it after it is
setup(at least this is my understanding). There still might be some issue on the side of
having the HW for building up the infra, but I'm really more worried on the
maintenance/people side.
 
2. Setting up the pipeline... I don't see much point in diving further until 1. is
solved, but to note we will need the same(in better case) OpenShift cluster or one
additional per each architecture.
.
.
.

My progress got really stalled over the past few weeks by need to work on Golang side of
the things in Fedora(security rebases, golang 1.15 change). 

I would very much appreciate any feedback or help,

JC
