It has been observed that some chroot operations spawn additional processes which rely on chroot files. More specifically, zypper, uses gpg-agent to import and validate gpg keys for its repositories. This gpg-agent process may stay alive for longer which prevents unmounting of the tmpfs directory since the gpg-agent process still uses libraries etc which were present in the chroot. We try to solve this by using walking all the pids in /proc to find out the running processes in the chroot and kill them gracefully. If that fails for whatever reason, then we simply keep trying to umount the tmpfs directory before we give up. The gpg-agent process usually terminates soon after its home directory disappears but on fast systems we can reach the 'umount tmpfs' point before gpg-agent terminates by itself. The solution is generic enough so other 'chroot processes' can also be handled appropriately. Change-Id: Iccf332678c79266113e76f062884fc5ee79e515d
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.
