Add images to the Image service
|
|
===============================
|
|
|
|
Instance (end-user) images
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Build or download the user images as described in :doc:`/user/creating-images`.
|
|
|
|
Load all the created images into the Image service, and note the image UUIDs in
|
|
the Image service for each one as it is generated.
|
|
|
|
- For *whole disk images* just upload the image:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create my-whole-disk-image --public \
|
|
--disk-format qcow2 --container-format bare \
|
|
--file my-whole-disk-image.qcow2
|
|
|
|
.. warning::
|
|
The kernel/ramdisk pair must not be set for whole disk images,
|
|
otherwise they'll be mistaken for partition images.
|
|
|
|
- For *partition images* to be used only with *local boot* (the default)
|
|
the ``img_type`` property must be set:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create my-image --public \
|
|
--disk-format qcow2 --container-format bare \
|
|
--property img_type=partition --file my-image.qcow2
|
|
|
|
- For *partition images* to be used with both *local* and *network* boot:
|
|
|
|
Add the kernel and ramdisk images to the Image service:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create my-kernel --public \
|
|
--disk-format aki --container-format aki --file my-image.vmlinuz
|
|
|
|
Store the image uuid obtained from the above step as ``MY_VMLINUZ_UUID``.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create my-image.initrd --public \
|
|
--disk-format ari --container-format ari --file 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
|
|
|
|
$ openstack image create my-image --public \
|
|
--disk-format qcow2 --container-format bare --property \
|
|
kernel_id=$MY_VMLINUZ_UUID --property \
|
|
ramdisk_id=$MY_INITRD_UUID --file my-image.qcow2
|
|
|
|
Deploy ramdisk images
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
#. Build or download the deploy images
|
|
|
|
The deploy images are used initially for preparing the server (creating disk
|
|
partitions) before the actual OS can be deployed.
|
|
|
|
There are several methods to build or download deploy images, please read
|
|
the :ref:`deploy-ramdisk` section.
|
|
|
|
#. Add the deploy images to the Image service
|
|
|
|
Add the deployment kernel and ramdisk images to the Image service:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create deploy-vmlinuz --public \
|
|
--disk-format aki --container-format aki \
|
|
--file ironic-python-agent.vmlinuz
|
|
|
|
Store the image UUID obtained from the above step as ``DEPLOY_VMLINUZ_UUID``
|
|
(or a different name when using the parameter specified by node architecture).
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create deploy-initrd --public \
|
|
--disk-format ari --container-format ari \
|
|
--file ironic-python-agent.initramfs
|
|
|
|
Store the image UUID obtained from the above step as ``DEPLOY_INITRD_UUID``
|
|
(or a different name when using the parameter specified by node architecture).
|
|
|
|
#. Configure the Bare Metal service to use the produced images. It can be done
|
|
per node as described in :doc:`enrollment` or in the configuration
|
|
file either using a dictionary to specify them by architecture as follows:
|
|
|
|
.. code-block:: ini
|
|
|
|
[conductor]
|
|
deploy_kernel_by_arch = {'x86_64': <insert DEPLOY_VMLINUZ_X86_64_UUID>,
|
|
'aarch64': <insert DEPLOY_VMLINUZ_AARCH64_UUID>}
|
|
deploy_ramdisk_by_arch = {'x86_64': <insert DEPLOY_INITRD_X86_64_UUID>,
|
|
'aarch64': <insert DEPLOY_INITRD_AARCH64_UUID>}
|
|
|
|
or globally using the general configuration parameters:
|
|
|
|
.. code-block:: ini
|
|
|
|
[conductor]
|
|
deploy_kernel = <insert DEPLOY_VMLINUZ_UUID>
|
|
deploy_ramdisk = <insert DEPLOY_INITRD_UUID>
|
|
|
|
In the case when both general parameters and parameters specified by
|
|
architecture are defined, the parameters specified by architecture take
|
|
priority.
