======================================================
Configuring the Bare Metal (ironic) service (optional)
======================================================
.. note::
This feature is experimental at this time and it has not been fully
production tested yet. These implementation instructions assume that
ironic is being deployed as the sole hypervisor for the region.
Ironic is an OpenStack project which provisions bare metal (as opposed to
virtual) machines by leveraging common technologies such as PXE boot and IPMI
to cover a wide range of hardware, while supporting pluggable drivers to allow
vendor-specific functionality to be added.
OpenStack's ironic project makes physical servers as easy to provision as
virtual machines in a cloud.
OpenStack-Ansible deployment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. Modify the environment files and force ``nova-compute`` to run from
within a container:
.. code-block:: bash
sed -i '/is_metal.*/d' /etc/openstack_deploy/env.d/nova.yml
Setup a neutron network for use by ironic
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In a general case, neutron networking can be a simple flat network. However,
in a complex case, this can be whatever you need and want. Ensure
you adjust the deployment accordingly. The following is an example:
.. code-block:: bash
neutron net-create cleaning-net --shared \
--provider:network_type flat \
--provider:physical_network ironic-net
neutron subnet-create ironic-net 172.19.0.0/22 --name ironic-subnet
--ip-version=4 \
--allocation-pool start=172.19.1.100,end=172.19.1.200 \
--enable-dhcp \
--dns-nameservers list=true 8.8.4.4 8.8.8.8
Building ironic images
~~~~~~~~~~~~~~~~~~~~~~
Images using the ``diskimage-builder`` must be built outside of a container.
For this process, use one of the physical hosts within the environment.
#. Install the necessary packages:
.. code-block:: bash
apt-get install -y qemu uuid-runtime curl
#. Install the ``disk-imagebuilder`` package:
.. code-block:: bash
pip install diskimage-builder --isolated
.. important::
Only use the ``--isolated`` flag if you are building on a node
deployed by OpenStack-Ansible, otherwise pip will not
resolve the external package.
#. Optional: Force the ubuntu ``image-create`` process to use a modern kernel:
.. code-block:: bash
echo 'linux-image-generic-lts-xenial:' > \
/usr/local/share/diskimage-builder/elements/ubuntu/package-installs.yaml
#. Create Ubuntu ``initramfs``:
.. code-block:: bash
disk-image-create ironic-agent ubuntu -o ${IMAGE_NAME}
#. Upload the created deploy images into the Image (glance) Service:
.. code-block:: bash
# Upload the deploy image kernel
glance image-create --name ${IMAGE_NAME}.kernel --visibility public \
--disk-format aki --container-format aki < ${IMAGE_NAME}.kernel
# Upload the user image initramfs
glance image-create --name ${IMAGE_NAME}.initramfs --visibility public \
--disk-format ari --container-format ari < ${IMAGE_NAME}.initramfs
#. Create Ubuntu user image:
.. code-block:: bash
disk-image-create ubuntu baremetal localboot local-config dhcp-all-interfaces grub2 -o ${IMAGE_NAME}
#. Upload the created user images into the Image (glance) Service:
.. code-block:: bash
# Upload the user image vmlinuz and store uuid
VMLINUZ_UUID="$(glance image-create --name ${IMAGE_NAME}.vmlinuz --visibility public --disk-format aki --container-format aki < ${IMAGE_NAME}.vmlinuz | awk '/\| id/ {print $4}')"
# Upload the user image initrd and store uuid
INITRD_UUID="$(glance image-create --name ${IMAGE_NAME}.initrd --visibility public --disk-format ari --container-format ari < ${IMAGE_NAME}.initrd | awk '/\| id/ {print $4}')"
# Create image
glance image-create --name ${IMAGE_NAME} --visibility public --disk-format qcow2 --container-format bare --property kernel_id=${VMLINUZ_UUID} --property ramdisk_id=${INITRD_UUID} < ${IMAGE_NAME}.qcow2
Creating an ironic flavor
~~~~~~~~~~~~~~~~~~~~~~~~~
#. Create a new flavor called ``my-baremetal-flavor``.
.. note::
The following example sets the CPU architecture for the newly created
flavor to be `x86_64`.
.. code-block:: bash
nova flavor-create ${FLAVOR_NAME} ${FLAVOR_ID} ${FLAVOR_RAM} ${FLAVOR_DISK} ${FLAVOR_CPU}
nova flavor-key ${FLAVOR_NAME} set cpu_arch=x86_64
nova flavor-key ${FLAVOR_NAME} set capabilities:boot_option="local"
.. note::
Ensure the flavor and nodes match when enrolling into ironic.
See the documentation on flavors for more information:
http://docs.openstack.org/openstack-ops/content/flavors.html
After successfully deploying the ironic node on subsequent boots, the instance
boots from your local disk as first preference. This speeds up the deployed
node's boot time. Alternatively, if this is not set, the ironic node PXE boots
first and allows for operator-initiated image updates and other operations.
.. note::
The operational reasoning and building an environment to support this
use case is not covered here.
Enroll ironic nodes
-------------------
#. From the utility container, enroll a new baremetal node by executing the
following:
.. code-block:: bash
# Source credentials
. ~/openrc
# Create the node
NODE_HOSTNAME="myfirstnodename"
IPMI_ADDRESS="10.1.2.3"
IPMI_USER="my-ipmi-user"
IPMI_PASSWORD="my-ipmi-password"
KERNEL_IMAGE=$(glance image-list | awk "/${IMAGE_NAME}.kernel/ {print \$2}")
INITRAMFS_IMAGE=$(glance image-list | awk "/${IMAGE_NAME}.initramfs/ {print \$2}")
ironic node-create \
-d agent_ipmitool \
-i ipmi_address="${IPMI_ADDRESS}" \
-i ipmi_username="${IPMI_USER}" \
-i ipmi_password="${IPMI_PASSWORD}" \
-i deploy_ramdisk="${INITRAMFS_IMAGE}" \
-i deploy_kernel="${KERNEL_IMAGE}" \
-n ${NODE_HOSTNAME}
# Create a port for the node
NODE_MACADDRESS="aa:bb:cc:dd:ee:ff"
ironic port-create \
-n $(ironic node-list | awk "/${NODE_HOSTNAME}/ {print \$2}") \
-a ${NODE_MACADDRESS}
# Associate an image to the node
ROOT_DISK_SIZE_GB=40
ironic node-update $(ironic node-list | awk "/${IMAGE_NAME}/ {print \$2}") add \
driver_info/deploy_kernel=$KERNEL_IMAGE \
driver_info/deploy_ramdisk=$INITRAMFS_IMAGE \
instance_info/deploy_kernel=$KERNEL_IMAGE \
instance_info/deploy_ramdisk=$INITRAMFS_IMAGE \
instance_info/root_gb=${ROOT_DISK_SIZE_GB}
# Add node properties
# The property values used here should match the hardware used
ironic node-update $(ironic node-list | awk "/${NODE_HOSTNAME}/ {print \$2}") add \
properties/cpus=48 \
properties/memory_mb=254802 \
properties/local_gb=80 \
properties/size=3600 \
properties/cpu_arch=x86_64 \
properties/capabilities=memory_mb:254802,local_gb:80,cpu_arch:x86_64,cpus:48,boot_option:local
Deploy a baremetal node kicked with ironic
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. important::
You will not have access unless you have a key set within nova before
your ironic deployment. If you do not have an ssh key readily
available, set one up with ``ssh-keygen``.
.. code-block:: bash
nova keypair-add --pub-key ~/.ssh/id_rsa.pub admin
Now boot a node:
.. code-block:: bash
nova boot --flavor ${FLAVOR_NAME} --image ${IMAGE_NAME} --key-name admin ${NODE_NAME}
