Build a custom base box for Terraform+Proxmox by downloading, extracting, tweaking, and packaging the stock ISO files.

Based on: https://github.com/Telmate/terraform-ubuntu-proxmox-iso

Supported:

• CentOS 7
• Ubuntu

• curl(1).
• sed(1).
• mkisofs(1) from the cdrtools package available from MacPorts or Homebrew.

The results are bootable ISO images and so should run on any i386 or amd64 or x86_64 hardware. They are only tested in Proxmox.

• Configurable default user with SSH key and sudoer NOPASSWD access
• The system clock is set to UTC
• Auto partition virtual disk (/dev/sda) with LVM
• OpenSSH server is installed
• Bring up only eth1 for flexible user-net SSH port forwarding
• Includes script to auto-resize partitions to the current size of vitual disk /etc/auto_resize_sda.sh

Note that the root password given in the config.sh file is in cleartext, and as such ends up in the ks.cfg or unattended.seed files inside the ISO!! You will have to change the templates for those files to change that.

This has been done this way, because OSX has no known way of encrypting sha512 passwords from the command line.

From the Ubuntu or CentOS directory, edit configuration in

config.sh

Now building the image:

./build-iso config.sh

The result can be found in the ../build directory. Downloaded ISO Images are cached in ../cache.
