Ironic - Bare Metal provisioning
|
|
================================
|
|
|
|
Overview
|
|
~~~~~~~~
|
|
Ironic works well in Kolla, though it is not currently tested as part of Kolla
|
|
CI, so may be subject to instability.
|
|
|
|
Pre-deployment Configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Enable Ironic in ``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
enable_ironic: "yes"
|
|
|
|
In the same file, define a network interface as the default NIC for dnsmasq,
|
|
a range of IP addresses that will be available for use by Ironic inspector,
|
|
as well as a network to be used for the Ironic cleaning network:
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_dnsmasq_interface: "eth1"
|
|
ironic_dnsmasq_dhcp_range: "192.168.5.100,192.168.5.110"
|
|
ironic_cleaning_network: "public1"
|
|
|
|
In the same file, optionally a default gateway to be used for the Ironic
|
|
Inspector inspection network:
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_dnsmasq_default_gateway: 192.168.5.1
|
|
|
|
In the same file, specify the PXE bootloader file for Ironic Inspector. The
|
|
file is relative to the ``/tftpboot`` directory. The default is ``pxelinux.0``,
|
|
and should be correct for x86 systems. Other platforms may require a different
|
|
value, for example aarch64 on Debian requires
|
|
``debian-installer/arm64/bootnetaa64.efi``.
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_dnsmasq_boot_file: pxelinux.0
|
|
|
|
Ironic inspector also requires a deploy kernel and ramdisk to be placed in
|
|
``/etc/kolla/config/ironic/``. The following example uses coreos which is
|
|
commonly used in Ironic deployments, though any compatible kernel/ramdisk may
|
|
be used:
|
|
|
|
.. code-block:: console
|
|
|
|
$ curl https://tarballs.openstack.org/ironic-python-agent/coreos/files/coreos_production_pxe.vmlinuz \
|
|
-o /etc/kolla/config/ironic/ironic-agent.kernel
|
|
|
|
$ curl https://tarballs.openstack.org/ironic-python-agent/coreos/files/coreos_production_pxe_image-oem.cpio.gz \
|
|
-o /etc/kolla/config/ironic/ironic-agent.initramfs
|
|
|
|
You may optionally pass extra kernel parameters to the inspection kernel using:
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_inspector_kernel_cmdline_extras: ['ipa-lldp-timeout=90.0', 'ipa-collect-lldp=1']
|
|
|
|
in ``/etc/kolla/globals.yml``.
|
|
|
|
Enable iPXE booting (optional)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
You can optionally enable booting via iPXE by setting ``enable_ironic_ipxe`` to
|
|
true in ``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
enable_ironic_ipxe: "yes"
|
|
|
|
This will enable deployment of a docker container, called ironic_ipxe, running
|
|
the web server which iPXE uses to obtain it's boot images.
|
|
|
|
The port used for the iPXE webserver is controlled via ``ironic_ipxe_port`` in
|
|
``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_ipxe_port: "8089"
|
|
|
|
The following changes will occur if iPXE booting is enabled:
|
|
|
|
- Ironic will be configured with the ``ipxe_enabled`` configuration option set
|
|
to true
|
|
- The inspection ramdisk and kernel will be loaded via iPXE
|
|
- The DHCP servers will be configured to chainload iPXE from an existing PXE
|
|
environment. You may also boot directly to iPXE by some other means e.g by
|
|
burning it to the option rom of your ethernet card.
|
|
|
|
Deployment
|
|
~~~~~~~~~~
|
|
Run the deploy as usual:
|
|
|
|
.. code-block:: console
|
|
|
|
$ kolla-ansible deploy
|
|
|
|
|
|
Post-deployment configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
A script named `init-runonce` is supplied as part of kolla-ansible to
|
|
initialise the cloud with some defaults (only to be used for demo purposes):
|
|
|
|
.. code-block:: console
|
|
|
|
tools/init-runonce
|
|
|
|
Add the deploy kernel and ramdisk to Glance. Here we're reusing the same images
|
|
that were fetched for the Inspector:
|
|
|
|
.. code-block:: console
|
|
|
|
openstack image create --disk-format aki --container-format aki --public \
|
|
--file /etc/kolla/config/ironic/ironic-agent.kernel deploy-vmlinuz
|
|
|
|
openstack image create --disk-format ari --container-format ari --public \
|
|
--file /etc/kolla/config/ironic/ironic-agent.initramfs deploy-initrd
|
|
|
|
Create a baremetal flavor:
|
|
|
|
.. code-block:: console
|
|
|
|
openstack flavor create --ram 512 --disk 1 --vcpus 1 my-baremetal-flavor
|
|
openstack flavor set my-baremetal-flavor --property \
|
|
resources:CUSTOM_BAREMETAL_RESOURCE_CLASS=1
|
|
|
|
Create the baremetal node and associate a port. (Ensure to substitute correct
|
|
values for the kernel, ramdisk, and MAC address for your baremetal node)
|
|
|
|
.. code-block:: console
|
|
|
|
openstack baremetal node create --driver ipmi --name baremetal-node \
|
|
--driver-info ipmi_port=6230 --driver-info ipmi_username=admin \
|
|
--driver-info ipmi_password=password \
|
|
--driver-info ipmi_address=192.168.5.1 \
|
|
--resource-class baremetal-resource-class --property cpus=1 \
|
|
--property memory_mb=512 --property local_gb=1 \
|
|
--property cpu_arch=x86_64 \
|
|
--driver-info deploy_kernel=15f3c95f-d778-43ad-8e3e-9357be09ca3d \
|
|
--driver-info deploy_ramdisk=9b1e1ced-d84d-440a-b681-39c216f24121
|
|
|
|
openstack baremetal port create 52:54:00:ff:15:55 --node 57aa574a-5fea-4468-afcf-e2551d464412
|
|
|
|
Make the baremetal node available to nova:
|
|
|
|
.. code-block:: console
|
|
|
|
openstack baremetal node manage 57aa574a-5fea-4468-afcf-e2551d464412
|
|
openstack baremetal node provide 57aa574a-5fea-4468-afcf-e2551d464412
|
|
|
|
It may take some time for the node to become available for scheduling in nova.
|
|
Use the following commands to wait for the resources to become available:
|
|
|
|
.. code-block:: console
|
|
|
|
openstack hypervisor stats show
|
|
openstack hypervisor show 57aa574a-5fea-4468-afcf-e2551d464412
|
|
|
|
Booting the baremetal
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
You can now use the following sample command to boot the baremetal instance:
|
|
|
|
.. code-block:: console
|
|
|
|
openstack server create --image cirros --flavor my-baremetal-flavor \
|
|
--key-name mykey --network public1 demo1
|
|
|
|
Notes
|
|
~~~~~
|
|
|
|
Debugging DHCP
|
|
--------------
|
|
The following `tcpdump` command can be useful when debugging why dhcp
|
|
requests may not be hitting various pieces of the process:
|
|
|
|
.. code-block:: console
|
|
|
|
tcpdump -i <interface> port 67 or port 68 or port 69 -e -n
|
|
|
|
Configuring the Web Console
|
|
---------------------------
|
|
Configuration based off upstream :ironic-doc:`Node web console
|
|
<admin/console.html#node-web-console>`.
|
|
|
|
Serial speed must be the same as the serial configuration in the BIOS settings.
|
|
Default value: 115200bps, 8bit, non-parity.If you have different serial speed.
|
|
|
|
Set ironic_console_serial_speed in ``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
ironic_console_serial_speed: 9600n8
|
|
|
|
Deploying using virtual baremetal (vbmc + libvirt)
