Simple question, but so far very difficult to answer... =-[
I am trying to deploy OpenShift (OKD) 4.5 or 4.7 as directed here Guide: Installing an OKD 4.5 Cluster. Look at the "Starting the control plane nodes" section.
I'm trying to create the cluster using an UPI (User Provisioned Infrastructure)/Bare Metal (KVM).
PROBLEM:
- Version 4.5
The master node cannot finish installation after reboot. It keeps showing the following error...
[ 1304.254380] ignition[485]: GET https://api-int.mbr.okd.local:22623/config/master: attempt #92
[ 1314.264629] ignition[485]: GET error: Get "https://api-int.mbr.okd.local:22623/config/master": net/http: timeout awaiting response headers
For version 4.5 we use "Fedora CoreOS 32.20200715.3.0".
- Version 4.7
The master node cannot finish installation after reboot. It keeps showing the following error...
[ 543.933709] ignition[505]: GET https://api-int.mbr.okd.local:22623/config/master: attempt #112
[ 543.939340] ignition[505]: GET error: Get "https://api-int.mbr.okd.loca1:22623/config/master": EOF
For version 4.7 we use "Fedora CoreOS 34.20210518.3.0".
I've waited hours and hours and the master nodes are still in the same situation. What can I do to resolve this?
Thanks! =D
