Create and add images to the Image service
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bare Metal provisioning requires two sets of images: the deploy images
and the user images. The deploy images are used by the Bare Metal service
to prepare the bare metal server for actual OS deployment. Whereas the
user images are installed on the bare metal server to be used by the
end user. Below are the steps to create the required images and add
them to the Image service:
#. The `disk-image-builder`_ can be used to create images required for
deployment and the actual OS which the user is going to run.
.. _disk-image-builder: http://docs.openstack.org/developer/diskimage-builder/
- Install diskimage-builder package (use virtualenv, if you don't
want to install anything globally):
.. code-block:: console
# pip install diskimage-builder
- Build the image your users will run (Ubuntu image has been taken as
an example):
- Partition images
.. code-block:: console
$ disk-image-create ubuntu baremetal dhcp-all-interfaces grub2 -o my-image
- Whole disk images
.. code-block:: console
$ disk-image-create ubuntu vm dhcp-all-interfaces -o my-image
The partition image command creates ``my-image.qcow2``,
``my-image.vmlinuz`` and ``my-image.initrd`` files. The ``grub2`` element
in the partition image creation command is only needed if local boot will
be used to deploy ``my-image.qcow2``, otherwise the images
``my-image.vmlinuz`` and ``my-image.initrd`` will be used for PXE booting
after deploying the bare metal with ``my-image.qcow2``.
If you want to use Fedora image, replace ``ubuntu`` with ``fedora`` in the
chosen command.
.. note:: To build the deploy image take a look at the :ref:`deploy-ramdisk`
section.
#. Add the user images to the Image service
Load all the images created in the below steps into the Image service,
and note the image UUIDs in the Image service for each one as it is
generated.
- Add the kernel and ramdisk images to the Image service:
.. code-block:: console
$ glance image-create --name my-kernel --visibility public \
--disk-format aki --container-format aki < my-image.vmlinuz
Store the image uuid obtained from the above step as ``MY_VMLINUZ_UUID``.
.. code-block:: console
$ glance image-create --name my-image.initrd --visibility public \
--disk-format ari --container-format ari < my-image.initrd
Store the image UUID obtained from the above step as ``MY_INITRD_UUID``.
- Add the *my-image* to the Image service which is going to be the OS
that the user is going to run. Also associate the above created
images with this OS image. These two operations can be done by
executing the following command:
.. code-block:: console
$ glance image-create --name my-image --visibility public \
--disk-format qcow2 --container-format bare --property \
kernel_id=$MY_VMLINUZ_UUID --property \
ramdisk_id=$MY_INITRD_UUID < my-image.qcow2
.. note:: To deploy a whole disk image, a kernel_id and a ramdisk_id
shouldn't be associated with the image. For example,
.. code-block:: console
$ glance image-create --name my-whole-disk-image --visibility public \
--disk-format qcow2 \
--container-format bare < my-whole-disk-image.qcow2
#. Add the deploy images to the Image service
Add the *my-deploy-ramdisk.kernel* and *my-deploy-ramdisk.initramfs* images
to the Image service:
.. code-block:: console
$ glance image-create --name deploy-vmlinuz --visibility public \
--disk-format aki --container-format aki < my-deploy-ramdisk.kernel
Store the image UUID obtained from the above step as ``DEPLOY_VMLINUZ_UUID``.
.. code-block:: console
$ glance image-create --name deploy-initrd --visibility public \
--disk-format ari --container-format ari < my-deploy-ramdisk.initramfs
Store the image UUID obtained from the above step as ``DEPLOY_INITRD_UUID``.
