While trying to get docker image pre-caching to work we couldn't get a docker daeomon to run within the chrooted environment. However we got docker running with the help of bwrap outside of the chrooted environment. The only option so far for this is the block-device.d phase. But this has the problem that it runs after the image size has been calculated. This leads to broken builds if the docker images being pulled are big. This can be solved by adding a post-root.d phase that runs outside the chroot but before the image size calculation. Change-Id: I36c2a81e2d9f5069f18ce5b0d52c5f1c7212c3ae
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 ubuntu
will 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.
