Hi folks,
Here is a quick and short update on what CI Infrastructure team has
been up to for the last few days.

# Done
*  identified infrastructure suitable for hosting the new ocp4 cluster
and curated inventory
* configured DNS for the new ocp4 ocp.ci.centos.org cluster
* provisioned 2 haproxy load balancers
* ansible template for PXE ocp4 nodes

# Hiccups we had
* Faced issue pulling machine config operator image from quay.io on
the ocp4 bootstrap node.  We reached out to Jonathan Lebon of Fedora
CoreOS related help (Thank you Jonathan for the help). The issue was
resolved by recreating the ignition files from scratch.
* Faced issue with multiple ethernet interfaces on the RHCOS nodes and
DHCP. Resolved by disabling DHCP, and configuring static IPs on a
single interface.

# In progress
* Provisioning OCP4 nodes (Master, Worker, and Bootstrap)

# Blockers
* RHEL CoreOS does not support RAID on the root device

Thank you and Stay Safe
