	SWH internal infrastructure preseeding configuration
	---------------------------------------------------------

	# Preseed

	Technology used to automate the debian installation per vm creation.

	# Generate preseed from template

	## Sample 1

	Generate a preseed for a vm for public facing interface (e.g front server):

	``` shell
	./generate_preseed.py \
	--hostname worker03 \
	--private-mac 52:54:00:1a:85:9e \
	--public-mac 52:54:00:be:26:34 \
	--public-ip 128.93.193.23 \
	--public-netmask 255.255.255.0 \
	--public-gateway 128.93.193.254 \
	--public-dns 193.51.196.130
	```

	## Sample 2

	Generate a preseed for a vm for internal use (e.g workers):

	``` shell
	./generate_preseed.py \
	--hostname icinga0 \
	--vmid 112 \
	--private-mac 8E:7D:DA:B5:42:83 \
	--ram 4096 \
	--private-ip 192.168.100.21 \
	--disk-specs proxmox-rbd:40G
	```

	Note:
	- You must be consistent with whatever you used on the proxmox ui [1]
	- The following information are provided in the proxmox ui after vm creation:
	- vmid
	- private-mac

	[1] https://louvre.internal.softwareheritage.org:8006

	# Run

	Pre-requisite, on the hypervisor:

	``` shell
	$ 7z x -o/tmp/debian-netinstall/ /var/lib/vz/template/iso/debian-$version-netinstall.iso
	$ cp -v /tmp/debian-install.amd/initrd.gz /tmp/initrd.gz
	$ cp -v /tmp/debian-install.amd/vmlinuz /tmp/linux
	```

	Generate the preseed, the output of the generation will explain what to do:

	``` shell
	$ ./generate_preseed.py -n icinga0 --private-ip 192.168.100.21 --vmid 112 --private-mac 8E:7D:DA:B5:42:83 --ram 4096 --disk-specs beaubourg-local:40G

	# >>>>> Local
	scp preseed_icinga0.cfg louvre.internal.softwareheritage.org:/tmp
	scp preseed_icinga0.cfg beaubourg.internal.softwareheritage.org:/tmp

	# >>>>> Remote on hypervisor
	cd /tmp; cp preseed_icinga0.cfg preseed.cfg; (cat initrd.gz; echo preseed.cfg \| cpio -Hnewc --quiet -o \| gzip -c) > initrd_112.gz

	qm create 112 -bootdisk scsi0 -cores 1 -hotplug disk,network,usb,cpu -ide2 none,media=cdrom -memory 4096 -name icinga0 -net0 virtio=8E:7D:DA:B5:42:83,bridge=vmbr0 -numa 0 -ostype l26 -scsihw virtio-scsi-pci -sockets 1 -startup order=4 -scsi0 beaubourg-local:vm-112-disk-1,size=40G -args '-kernel /tmp/linux -initrd /tmp/initrd_112.gz'
	pvesm alloc beaubourg-local 112 vm-112-disk-1 40G --format raw
	qm start 112
	while qm status 112 \| grep -q running; do sleep 10; done
	qm set 112 -delete args
	qm start 112

	```

	# Pre-requisite

	Install the `./preseed/finish.sh` script in the
	debian.internal.softwareheritage.org apache server:
	http://debian.internal.softwareheritage.org/installer/finish.sh
