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
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.
