# "disk_setup": disk partitioning
# --------------------------------
# The disk_setup directive instructs Cloud-init to partition a disk. The format is:
disk_setup:
ephemeral0:
table_type: 'mbr'
layout: true
/dev/xvdh:
table_type: 'gpt'
layout:
- 33
- [33, 82]
- [33, '44479540-F297-41B2-9AF7-D131D5F0458A']
overwrite: True
# The format is a list of dicts of dicts. The first value is the name of the
# device and the subsequent values define how to create and layout the
# partition.
# The general format is:
# disk_setup:
# :
# table_type: 'mbr'|'gpt'
# layout:
# overwrite:
#
# Where:
# : The name of the device. 'ephemeralX' and 'swap' are special
# values which are specific to the cloud. For these devices
# Cloud-init will look up what the real devices is and then
# use it.
#
# For other devices, the kernel device name is used. At this
# time only simply kernel devices are supported, meaning
# that device mapper and other targets may not work.
#
# Note: At this time, there is no handling or setup of
# device mapper targets.
#
# table_type=: Currently the following are supported:
# 'mbr': default and setups a MS-DOS partition table
# 'gpt': setups a GPT partition table
#
# Note: At this time only 'mbr' and 'gpt' partition tables
# are allowed. It is anticipated in the future that
# we'll also have "RAID" to create a mdadm RAID.
#
# layout={...}: The device layout. This is a list of values, with the
# percentage of disk that partition will take.
# Valid options are:
# [, [, is the _percentage_ of the disk to use, while
# is either the numerical value of the partition type
# (two digit code from fdisk, four digit code from gdisk) or a full
# GPT partition GUID.
#
# The following setups two partitions, with the first
# partition having a swap label, taking 1/3 of the disk space
# and the remainder being used as the second partition.
# /dev/xvdh':
# table_type: 'mbr'
# layout:
# - [33,82]
# - 66
# overwrite: True
#
# When layout is "true" it means single partition the entire
# device.
#
# When layout is "false" it means don't partition or ignore
# existing partitioning.
#
# If layout is set to "true" and overwrite is set to "false",
# it will skip partitioning the device without a failure.
#
# overwrite=: This describes whether to ride with safetys on and
# everything holstered.
#
# 'false' is the default, which means that:
# 1. The device will be checked for a partition table
# 2. The device will be checked for a filesystem
# 3. If either a partition of filesystem is found, then
# the operation will be _skipped_.
#
# 'true' is cowboy mode. There are no checks and things are
# done blindly. USE with caution, you can do things you
# really, really don't want to do.

# fs_setup describes the how the filesystems are supposed to look.
