Hi, can you modify iso file to use static ips instead of pxeboot/dhcp combo.? Have you tried this option? Christensen of Redhat did it in 4.4 ocp . but I failed in okd/ocp 4.6 +

devopstales commented 2 years ago

@tkvinfolio As I know that configuration not working after 4.6. As I remember I tried and failed too, so we switched to this solution.

@devopstales wow, nice of you to reply as soon as possible. I am grateful. Never ever I get such a quick reply. Can I install 4.6, using CD image massaging with static IPs, then upgrade it to 4.7 or 4.8 following the upgrade path?

devopstales commented 2 years ago

@tkvinfolio I think you can start with 4.6 an upgrade to 4.8. My cluster died in an upgrade from 4.8 to 4.9. The answr on the forums was to try to upgrade to 4.10. It is working but some of the operators degraded, and I cannot fix them, so I plan to reinstall the cluster. Good Luck.

the fedora coreos build 33.20210117.3.2 is not available to download? can you send a link? I was able to hack the URL and get the ISO and OVA (wget https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/33.20210117.3.2/x86_64/fedora-coreos-33.0117.3.2-live.x86_64.iso ) How would I get older builds? However if I get the recent builds, and use the 4.6 installer given here as wget command, can I get this going to install 4.6 okd?

@devopstales were you successful in reinstalling the cluster?

Hi @tkvinfolio I ditched OKD in favor of rke2. You can download the latest iso from fedoracoreos's page. The c32 files are from the package syslinux-tftpboot that originally put this files under /usr/share/syslinux/
