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