coreos-assembler v0.6.0
As part of creating Fedora CoreOS (and derivatives like Red Hat Enterprise Linux CoreOS),
we are making some fairly fundamental changes to how the operating system works - while
OSTree isn't new to Fedora, Ignition is - and more broadly than that, using Ignition
implies something much more similar to the Container Linux experience where installation
is via "dd to disk".
We created https://github.com/coreos/coreos-assembler as a new, opinionated tool designed
to bind together Ignition, rpm-ostree, while carrying forward a lot of the Container Linux
tooling from the https://github.com/coreos/mantle/ project around uploading to IaaS
clouds, running tests (kola) etc.
https://github.com/coreos/coreos-assembler/releases/tag/v0.6.0
is the 0.6.0 release.
coreos-assembler comes as a container image (ready to run via "rootless" podman
for example), not an RPM. We may try to add it to the Fedora container buildsystem at
some point, but the reason I'd like to occasionally highlight releases here is because
part of the intention is that coreos-assembler should be an easy onramp for people and
projects that want a "custom" Fedora CoreOS style system.
For example, I'd like for in the future for Fedora Silverblue and Fedora IoT to be
*derivatives* of Fedora CoreOS.
And today, RHEL CoreOS (part of OpenShift 4) is created via coreos-assembler, although
it's RHEL content obviously.
There are obviously a *ton* of "build systems" out there - but I think so far
coreos-assembler has been working well as a way to make "CoreOS style systems";
for anyone who is interested in that (or wants to contribute to Fedora CoreOS), please
take a look!
