Because we are using the building platform's "yum" to do the initial install into the chroot, it is affected by the base-system's /etc/yum.conf. pip-and-virtaulenv in I82acb865378a0fa5903a6267bfcee0e2962eced0 added "exclude=python-pip..." in /etc/yum.conf to stop the package manager overwriting the installed pip. Now our CI images have built with this, we are now picking up this exclude on centos. Since on F24 dnf->python->python-pip we end up failing to build the the chroot because python-pip can not be satisifed. In a general sense, however, this could be caused by any configuration put into /etc/yum.conf that is incompatible with installing into the chroot. yum has the option to disable all excludes which is used here. This seems to be the best way to isolate the chroot install from any excludes that may have been done on the base system for various reasons. I did consider using a completely separate yum.conf we ship with dib ... but let's start simple. This should fix the current gate failures on centos Change-Id: I4e4cc8ed09a29c4057ade34ea93025139e191bf5
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=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty 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.
