adhoc-provision-node-qa.yml

---
# This playbook is an ad-hoc task used to deploy bare-metal nodes
# It used the following variables, declared through inventory (group/host vars):
#  centos_version: 7  # default centos version deployed
#  rhel_version:      # if rhel_version is defined, we'll deploy RHEL instead
#  arch: x86_64       # default architecture
#  root_pass:         # default root_password on provisioned nodes
#  deploy_host:       # node hosting pxelinux.cfg configurations
#  ipmitool_host:     # node with ipmitool and mgmt vlan access
#  ks_url: http://your.node/path/to/ks_dir # where to find the generated kickstarts
#  use_md_raid: True # Default to use md_raid for /dev/sda and /dev/sdb
#  md_raid_level: 1
#  hdd_install_dev: sda # default but can point to mpatha for multipath, etc
#  pxe_boot_serial: False # boolean if we only have serial console like on seamicro chassis
#  lv_root_size: 10000 # in GB
#  lv_root_expand: False  # do we want to have / to max capacity of the VG ?
#  lv_home_size: 2048 # in GB
#  pxe_bootdev: eth0 # device used as bootdev and first interface configured
#  bridge_nic: False # If set to True, pxe_bootdev will become the bridgeslave device for br0 bridge
#  rhel_verion: 9    # If defined, it will be installed with RHEL instead of centos
# Call this adhoc playbook with --limit to deploy host[s]/group
#
