Lucas Alvares Gomes 25d3ee5471 Add dynamic-login element Troubleshooting an image can be quite hard, specially if you can not get a prompt you can enter commands to find out what went wrong. By default, the images (specially ramdisks) doesn't have any SSH key or password for any user. Of course one could use the ``devuser`` element to generate an image with SSH keys and user/password in the image but that would be a massive security hole and very it's discouraged to run in production with a ramdisk like that. This commit is adding a new element called dynamic-login, which inserts a helper script into the image to allow operators to inject a SSH key and/or change the root password dynamically when it boots via parameters in the kernel command line. Those parameters are: sshkey = If the operator append sshkey="$PUBLIC_SSH_KEY" to the kernel command line on boot, the helper script will append this key to the root user authorized_keys. rootpwd = If the operator append rootpwd="$ENCRYPTED_PASSWORD" to the kernel command line on boot, the helper script will set the root password to the one specified by this option. Note that this password should be an encrypted password. Change-Id: I6b87a1b90163d79745f30dfacd37516051fa0aea		2015-11-20 17:02:54 +00:00

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 <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images.  They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<http://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
