To create an alpine base image:

Spin up a new VM:

• 512MB RAW Disk image (hence called alpine.img)
• Virtio Network bridge
• ISO of Alpine Virtual ed. attached

Inside the VM:

• Add the following to /etc/network/interfaces:

  auto lo iface lo inet loopback

  auto eth0 iface eth0 inet dhcp hostname alpine

• /etc/init.d/networking restart

• Run setup-alpine:

  • gb
  • gb
  • alpine
  • eth0
  • dhcp
  • no
  • [Enter twice]
  • UTC
  • none
  • 1
  • openssh
  • busybox
  • sda
  • sys
  • y

• passwd -d root

• poweroff

Make sure the VM is stopped.

Run virt-sysprep -a alpine.img

Run xz -k -verbose -T4 --best --block-size=16777216 alpine.img

Create the index file as below. <> Shows commands to generate the required data. Replace version as needed.

[alpine-37]
name=Alpine 3.7
osinfo=alpine
arch=x86_64
file=alpine.img.xz
checksum=<sha512sum alpine.img.xz>
format=raw
size=<du -s alpine.img>
compressed_size=<du -s alpine.img.xz>
expand=/dev/sda3

Sign the index file: gpg --clearsign --armor index

Upload the generated index.asc and alpine.img.xz files to a web server.
