Re: OKD 4.x

[Clayton Coleman]

The cluster bootstrap process uses ignition to ensure masters join the
cluster, and there are a number of aspects of how upgrades of control plane
nodes work that assume the ability to use ostree to update and pivot the
nodes during boot to the correct content set.

I’m sure it’s possible to get a cluster working without a coreos-style OS
(ignition, pivot, ostree), but it would lack the ability to update itself,
so it wouldn’t really be a coherent whole.  The work in fcos is probably
the place to start (we still have to spec out the details, which is on me)
just because it works together with the cluster rather than being distinct.

Hi Clayton,



Will there still be support for Centos 8 witjout the CoreOS spin ? Or will
OKD/Openshift 4 only work with a CoreOS based system ?



Cheers

We’re currently working on how Fedora CoreOS will integrate into OKD.
There’s a fair chunk of work that needs to be done and FCoS has a broader
mission than RHCoS does, so its a bit further behind (since OpenShift 4 /
OKD 4 require an OS with ignition and ostree).  Stay tuned, I was going to
write out a work plan for this and share it here.  There’s no current plan
for a centos version, since there’s a lot of interest in FCoS for a newer
kernel.



Until that happens, try.openshift.com makes it easy to get an evaluation of
OCP4 for test and development even if you don’t have a subscription.

Does any body know if  there is any plan for OKD 4.x ? I am unable to find
any information regarding OKD especially for bare metal.

Here
is
a documentation for installing the container-platform on bare-metal which
uses Red Hat Enterprise Linux CoreOS(RHCOS) which presuppose red hat
subscription. RHCOS will not be possible though to use on OKD - Is there
something like CentOS for CoreOS ?
