There is currently no automated way of growing LVM volumes on boot like single partition images do with their growroot mechanism. This lack likely contributes to LVM not being widely used on VM and baremetal workloads, since growing to the full disk requires workload knowledge to determine which volumes to grow and by what amount. The growvols element contributes a growvols python script which can be run on firstboot (via systemd or cloud-init) or manually via automation such as ansible. It is also an interactive script which displays the full list of modifying commands before prompting for confirmation to run them all. By default the script will grow the root volume, but arguments allow any volume to grow by a specified amount, or a percentage of the available disk space.

Image building tools for OpenStack
diskimage-builder
is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu
will create a bootable Ubuntu Bionic based qcow2
image.
diskimage-builder
is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
