A profile is a namespace for additional settings that can be applied by KIWI NG on top of the default settings (or other profiles), thereby allowing to build multiple appliances with the same build type but with different configurations.
The use of profiles is advisable to distinguish image builds of the same
type but with different settings. In the following example, two virtual
machine images of the vmx type are configured: one for QEMU (using the
qcow2 format) and one for VMWare (using the
<image schemaversion="7.2" name="LimeJeOS-Leap-15.1"> <profiles> <profile name="QEMU" description="virtual machine for QEMU"/> <profile name="VMWare" description="virtual machine for VMWare"/> </profiles> <preferences> <version>15.0</version> <packagemanager>zypper</packagemanager> </preferences> <preferences profiles="QEMU"> <type image="vmx" format="qcow2" filesystem="ext4"> </preferences> <preferences profiles="VMWare"> <type image="vmx" format="vmdk" filesystem="ext4"> </preferences> </image>
Each profile is declared via the element
profile, which itself must be a
profiles and must contain the
description is only present for documentation purposes,
name on the other hand is used to instruct KIWI NG which profile to build
via the command line. Additionally, one can provide the boolean attribute
import, which defines whether this profile should be used by default when
KIWI NG is invoked via the command line.
A profile inherits the default settings which do not belong to any
profile. It applies only to elements that contain the profile in their
profiles attribute. The attribute
profiles expects a comma separated
list of profiles for which the settings of this element apply.
Profiles can furthermore inherit settings from another profile via the
<profiles> <profile name="VM" description="virtual machine"/> <profile name="QEMU" description="virtual machine for QEMU"> <requires profile="VM"/> </profile> </profiles>
QEMU would inherit the settings from
VM in the above
