By default, we attempt to inject a serial console, which may, or may not be needed, for example, Centos Stream 9 cloud images already configure a console setting, and repeating it just might be undesirable and cause workload performance degredation if the kernel or an application has to report anything to a console. This change generally results in original console entries being preserved, which might actually be a bug and get fixed in a latter patch. Generally, users of dib *should* likely be specific what they want to do with their console setting, and without setting the new DIB_BOOTLOADER_USE_SERIAL_CONSOLE paramter to false, the default will be adhered to, and any pre-existing serial console entries will *not* be de-duplicated from the base image. That too is *likely* a bug, but a harder one to fix. Change-Id: Icdfb5ed021b1a91e2de3c9a22bb2ff7fe9882bcd
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.
