The build flag enables community-only modifications to the installer
This adds `Dockerfile.okd` image, which has RHCOS bootimage locations replaced with FCOS counterparts.
Update CVO upstream setting from OCP Cincinnati to OKD's release-controller
Some platforms are not supported by OKD installer, so these should be skipped. initramfs, iso and kernel have different formats in fcos meta file. Official Azure image is not yet uploaded to the Marketplace
OKD is using plain FCOS, which doesn't have MCD binary to pivot. It should extract it from machine-config-daemon image and run pivot manually. This also extract necessary files and manifests from machine-os-content image
This is noop on RHCOS, but useful for OKD. If an older stable image is used Zincati may update bootstrap node during bootstrapping, so it should be disabled
In 4.6+ `authentication` operator needs additional setting to allow single kube-apiserver instance.
Change source_uri to source because on OKD we download the FCOS image locally before uploading it to Azure.
Set DNS_IP via systemd-resolved if the service is running
Single `wait` seems to hang on recent FCOS
