Packer templates for OpenSLX
Packer-based generation of reference systems using distro's ISOs.
Dependencies
Packer => 0.12.2
Download: https://www.packer.io/downloads.html
Usage
The file 'base.json' contains default variables (VM, SSH) common to all templates.
Thus it should always be included using packer's '-var-file' option.
Basic usage:
packer build -var-file=base.json
Example: build Ubuntu 16.04.2 LTS template using qemu builder
packer build -var-file=base.json -only=qemu ubuntu-16.04-amd64.json
Debug:
PACKER_LOG=1 PACKER_LOG_FILE=/var/log/packer.log \
packer build -debug -only=qemu -var-file=base.json ubuntu-16.04-amd64.json
Notes
Variables set in base.json can be overriden using packer's '-var' options, e.g.:
packer build -var-file=base.json -var='headless=true'
(Make sure you first include base.json before overriding a variable!)
Packer connects to the VM per SSH to provision them after the initial iso installation.
A default password is defined in base.json and the corresponding SHA-512 hashes are set
in the kickstart/preseed files. If you change the 'ssh_password' make sure to change the
hashes in the ks/ps files (generate with 'mkpasswd -m sha-512')!
While the qemu builder produces a qcow2 image, it can be further compressed using:
virt-sparsify --compress
