Red Hat Summit7.2. The Provisioning Template PXELinux Discovery Snippet
For BIOS provisioning, the PXELinux global default template in the Hosts > Provisioning Templates window contains the snippet pxelinux_discovery. The snippet has the following lines:
LABEL discovery MENU LABEL Foreman Discovery Image KERNEL boot/fdi-image/vmlinuz0 APPEND initrd=boot/fdi-image/initrd0.img rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=<%= foreman_server_url %> proxy.type=foreman IPAPPEND 2
LABEL discovery
MENU LABEL Foreman Discovery Image
KERNEL boot/fdi-image/vmlinuz0
APPEND initrd=boot/fdi-image/initrd0.img rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=<%= foreman_server_url %> proxy.type=foreman
IPAPPEND 2
The KERNEL and APPEND options boot the Discovery image and ramdisk. The APPEND option contains a proxy.url parameter, with the foreman_server_url macro as its argument. This macro resolves to the full URL of Satellite Server.
For UEFI provisioning, the PXEgrub2 global default template in the Hosts > Provisioning Templates window contains the snippet pxegrub2_discovery:
menuentry 'Foreman Discovery Image' --id discovery {
linuxefi boot/fdi-image/vmlinuz0 rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=<%= foreman_server_url %> proxy.type=foreman BOOTIF=01-$mac
initrdefi boot/fdi-image/initrd0.img
}
menuentry 'Foreman Discovery Image' --id discovery {
linuxefi boot/fdi-image/vmlinuz0 rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=<%= foreman_server_url %> proxy.type=foreman BOOTIF=01-$mac
initrdefi boot/fdi-image/initrd0.img
}
To use Capsule to proxy the discovery steps, edit /var/lib/tftpboot/pxelinux.cfg/default or /var/lib/tftpboot/grub2/grub.cfg and change the URL to the Capsule Server FQDN you want to use.
The global template is available on Satellite Server and all Capsules that have the TFTP feature enabled.
