Raw Blame History

Bare Metal Service Installation Guide

This document pertains to the Kilo (2015.1) release of OpenStack Ironic. Users of earlier releases may encounter differences, and are encouraged to look at earlier versions of this document for guidance.

Service Overview

The Bare Metal Service is a collection of components that provides support to manage and provision physical machines.

Also known as the Ironic project, the Bare Metal Service may, depending upon configuration, interact with several other OpenStack services. This includes:

the Telemetry (Ceilometer) for consuming the IPMI metrics
the Identity Service (Keystone) for request authentication and to locate other OpenStack services
the Image Service (Glance) from which to retrieve images and image meta-data
the Networking Service (Neutron) for DHCP and network configuration
the Compute Service (Nova) works with Ironic and acts as a user-facing API for instance management, while Ironic provides the admin/operator API for hardware management. Nova also provides scheduling facilities (matching flavors <-> images <-> hardware), tenant quotas, IP assignment, and other services which Ironic does not, in and of itself, provide.
the Block Storage (Cinder) will provide volumes, but the aspect is not yet available.

The Bare Metal Service includes the following components:

ironic-api: A RESTful API that processes application requests by sending them to the ironic-conductor over RPC.
ironic-conductor: Adds/edits/deletes nodes; powers on/off nodes with ipmi or ssh; provisions/deploys/decommissions bare metal nodes.
ironic-python-agent: A python service which is run in a temporary ramdisk to provide ironic-conductor service(s) with remote access and in-band hardware control.
python-ironicclient: A command-line interface (CLI) for interacting with the Bare Metal Service.

Additionally, the Bare Metal Service has certain external dependencies, which are very similar to other OpenStack Services:

A database to store hardware information and state. You can set the database backend type and location. A simple approach is to use the same database backend as the Compute Service. Another approach is to use a separate database backend to further isolate bare metal resources (and associated metadata) from users.
A queue. A central hub for passing messages. It should use the same implementation as that of the Compute Service (typically RabbitMQ).

Optionally, one may wish to utilize the following associated projects for additional functionality:

ironic-discoverd; An associated service which performs in-band hardware introspection by PXE booting unregistered hardware into a "discovery ramdisk".

- diskimage-builder; May be used to customize machine images, create and: discovery deploy ramdisks, if necessary.

Install and Configure Prerequisites

The Bare Metal Service is a collection of components that provides support to manage and provision physical machines. You can configure these components to run on separate nodes or the same node. In this guide, the components run on one node, typically the Compute Service's compute node.

This section shows you how to install and configure the components.

It assumes that the Identity Service, Image Service, Compute Service, and Networking Service have already been set up.

Configure Identity Service for Bare Metal

Create the Bare Metal service user (eg ironic). The service uses this to authenticate with the Identity Service. Use the service tenant and give the user the admin role:
```
keystone user-create --name=ironic --pass=IRONIC_PASSWORD --email=ironic@example.com
keystone user-role-add --user=ironic --tenant=service --role=admin
```
You must register the Bare Metal Service with the Identity Service so that other OpenStack services can locate it. To register the service:
```
keystone service-create --name=ironic --type=baremetal \
--description="Ironic bare metal provisioning service"
```
Use the id property that is returned from the Identity Service when registering the service (above), to create the endpoint, and replace IRONIC_NODE with your Bare Metal Service's API node:
```
keystone endpoint-create \
--service-id=the_service_id_above \
--publicurl=http://IRONIC_NODE:6385 \
--internalurl=http://IRONIC_NODE:6385 \
--adminurl=http://IRONIC_NODE:6385
```

Error

If the keystone endpoint-create operation returns an error about not being able to find the region "regionOne", the error is due to this keystone bug: https://bugs.launchpad.net/keystone/+bug/1400589. As a workaround until that bug is fixed you can force the creation of "RegionOne" by passing --region=RegionOne as an argument to the keystone endpoint-create command.

Set up the Database for Bare Metal

The Bare Metal Service stores information in a database. This guide uses the MySQL database that is used by other OpenStack services.

In MySQL, create an ironic database that is accessible by the ironic user. Replace IRONIC_DBPASSWORD with the actual password:

# mysql -u root -p
mysql> CREATE DATABASE ironic CHARACTER SET utf8;
mysql> GRANT ALL PRIVILEGES ON ironic.* TO 'ironic'@'localhost' \
IDENTIFIED BY 'IRONIC_DBPASSWORD';
mysql> GRANT ALL PRIVILEGES ON ironic.* TO 'ironic'@'%' \
IDENTIFIED BY 'IRONIC_DBPASSWORD';

Install the Bare Metal Service

Install from packages:

# Available in Ubuntu 14.04 (trusty)
apt-get install ironic-api ironic-conductor python-ironicclient

Configure the Bare Metal Service

The Bare Metal Service is configured via its configuration file. This file is typically located at /etc/ironic/ironic.conf.

Although some configuration options are mentioned here, it is recommended that you review all the available options so that the Bare Metal Service is configured for your needs.

The Bare Metal Service stores information in a database. This guide uses the MySQL database that is used by other OpenStack services.

Configure the location of the database via the connection option. In the following, replace IRONIC_DBPASSWORD with the password of your ironic user, and replace DB_IP with the IP address where the DB server is located:
```
[database]
...

# The SQLAlchemy connection string used to connect to the
# database (string value)
#connection=<None>
connection = mysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic?charset=utf8
```

Configure the Bare Metal Service to use the RabbitMQ message broker by setting one or more of these options. Replace RABBIT_HOST with the address of the RabbitMQ server.:

[DEFAULT]
...
# The RabbitMQ broker address where a single node is used
# (string value)
rabbit_host=RABBIT_HOST

# The RabbitMQ userid (string value)
#rabbit_userid=guest

# The RabbitMQ password (string value)
#rabbit_password=guest

# The RabbitMQ virtual host (string value)
#rabbit_virtual_host=/

Configure the Bare Metal Service to use these credentials with the Identity Service. Replace IDENTITY_IP with the IP of the Identity server, and replace IRONIC_PASSWORD with the password you chose for the ironic user in the Identity Service:

[DEFAULT]
...
# Method to use for authentication: noauth or keystone.
# (string value)
auth_strategy=keystone

...
[keystone_authtoken]

# Host providing the admin Identity API endpoint (string
# value)
#auth_host=127.0.0.1
auth_host=IDENTITY_IP

# Port of the admin Identity API endpoint (integer value)
#auth_port=35357

# Protocol of the admin Identity API endpoint(http or https)
# (string value)
#auth_protocol=https

# Complete public Identity API endpoint (string value)
#auth_uri=<None>
auth_uri=http://IDENTITY_IP:5000/

# Keystone account username (string value)
#admin_user=<None>
admin_user=ironic

# Keystone account password (string value)
#admin_password=<None>
admin_password=IRONIC_PASSWORD

# Keystone service account tenant name to validate user tokens
# (string value)
#admin_tenant_name=admin
admin_tenant_name=service

# Directory used to cache files related to PKI tokens (string
# value)
#signing_dir=<None>

Set the URL (replace NEUTRON_IP) for connecting to the Networking service, to be the Networking service endpoint:
```
[neutron]

# URL for connecting to neutron. (string value)
#url=http://127.0.0.1:9696
url=http://NEUTRON_IP:9696
```

Configure the Bare Metal Service so that it can communicate with the Image Service. Replace GLANCE_IP with the hostname or IP address of the Image Service:

[glance]

# A list of URL schemes that can be downloaded directly via
# the direct_url.  Currently supported schemes: [file]. (list
# value)
#allowed_direct_url_schemes=

# Default glance hostname or IP address. (string value)
#glance_host=$my_ip
glance_host=GLANCE_IP

# Default glance port. (integer value)
#glance_port=9292

# Default protocol to use when connecting to glance. Set to
# https for SSL. (string value)
#glance_protocol=http

# A list of the glance api servers available to nova. Prefix
# with https:// for SSL-based glance API servers. Format is
# [hostname|IP]:port. (string value)
#glance_api_servers=<None>

Create the Bare Metal Service database tables:

ironic-dbsync --config-file /etc/ironic/ironic.conf create_schema

Restart the Bare Metal Service:

service ironic-api restart
service ironic-conductor restart

Configure Compute Service to use the Bare Metal Service

The Compute Service needs to be configured to use the Bare Metal Service's driver. The configuration file for the Compute Service is typically located at /etc/nova/nova.conf. This configuration file must be modified on the Compute Service's controller nodes and compute nodes.

Change these configuration options in the default section, as follows:

[default]

# Driver to use for controlling virtualization. Options
# include: libvirt.LibvirtDriver, xenapi.XenAPIDriver,
# fake.FakeDriver, baremetal.BareMetalDriver,
# vmwareapi.VMwareESXDriver, vmwareapi.VMwareVCDriver (string
# value)
#compute_driver=<None>
compute_driver=nova.virt.ironic.IronicDriver

# Firewall driver (defaults to hypervisor specific iptables
# driver) (string value)
#firewall_driver=<None>
firewall_driver=nova.virt.firewall.NoopFirewallDriver

# The scheduler host manager class to use (string value)
#scheduler_host_manager=nova.scheduler.host_manager.HostManager
scheduler_host_manager=nova.scheduler.ironic_host_manager.IronicHostManager

# Virtual ram to physical ram allocation ratio which affects
# all ram filters. This configuration specifies a global ratio
# for RamFilter. For AggregateRamFilter, it will fall back to
# this configuration value if no per-aggregate setting found.
# (floating point value)
#ram_allocation_ratio=1.5
ram_allocation_ratio=1.0

# Amount of disk in MB to reserve for the host (integer value)
#reserved_host_disk_mb=0
reserved_host_memory_mb=0

# Full class name for the Manager for compute (string value)
#compute_manager=nova.compute.manager.ComputeManager
compute_manager=ironic.nova.compute.manager.ClusteredComputeManager

# Flag to decide whether to use baremetal_scheduler_default_filters or not.
# (boolean value)
#scheduler_use_baremetal_filters=False
scheduler_use_baremetal_filters=True

Change these configuration options in the ironic section. Replace:
- IRONIC_PASSWORD with the password you chose for the ironic user in the Identity Service
- IRONIC_NODE with the hostname or IP address of the ironic-api node
- IDENTITY_IP with the IP of the Identity server

[ironic]

# Ironic keystone admin name
admin_username=ironic

#Ironic keystone admin password.
admin_password=IRONIC_PASSWORD

# keystone API endpoint
admin_url=http://IDENTITY_IP:35357/v2.0

# Ironic keystone tenant name.
admin_tenant_name=service

# URL for Ironic API endpoint.
api_endpoint=http://IRONIC_NODE:6385/v1

On the Compute Service's controller nodes, restart nova-scheduler process:
```
service nova-scheduler restart
```
On the Compute Service's compute nodes, restart the nova-compute process:
```
service nova-compute restart
```

Configure Neutron to communicate with the Bare Metal Server

Neutron needs to be configured so that the bare metal server can communicate with the OpenStack Networking service for DHCP, PXE Boot and other requirements. This section describes how to configure Neutron for a single flat network use case for bare metal provisioning.

You will also need to provide Ironic with the MAC address(es) of each Node that it is provisioning; Ironic in turn will pass this information to Neutron for DHCP and PXE Boot configuration. An example of this is shown in the Enrollment section.

Edit /etc/neutron/plugins/ml2/ml2_conf.ini and modify these:

[ml2]
type_drivers = flat
tenant_network_types = flat
mechanism_drivers = openvswitch

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vlan]
network_vlan_ranges = physnet1

[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True

[ovs]
bridge_mappings = physnet1:br-eth2
# Replace eth2 with the interface on the neutron node which you
# are using to connect to the bare metal server

If neutron-openvswitch-agent runs with ovs_neutron_plugin.ini as the input config-file, edit ovs_neutron_plugin.ini to configure the bridge mappings by adding the [ovs] section described in the previous step, and restart the neutron-openvswitch-agent.
Add the integration bridge to Open vSwitch:
```
ovs-vsctl add-br br-int
```
Create the br-eth2 network bridge to handle communication between the OpenStack (and Bare Metal services) and the bare metal nodes using eth2. Replace eth2 with the interface on the neutron node which you are using to connect to the Bare Metal Service:
```
ovs-vsctl add-br br-eth2
ovs-vsctl add-port br-eth2 eth2
```

Restart the Open vSwitch agent:

service neutron-plugin-openvswitch-agent restart

On restarting the Neutron Open vSwitch agent, the veth pair between the bridges br-int and br-eth2 is automatically created.

Your Open vSwitch bridges should look something like this after following the above steps:

ovs-vsctl show

    Bridge br-int
        fail_mode: secure
        Port "int-br-eth2"
            Interface "int-br-eth2"
                type: patch
                options: {peer="phy-br-eth2"}
        Port br-int
            Interface br-int
                type: internal
    Bridge "br-eth2"
        Port "phy-br-eth2"
            Interface "phy-br-eth2"
                type: patch
                options: {peer="int-br-eth2"}
        Port "eth2"
            Interface "eth2"
        Port "br-eth2"
            Interface "br-eth2"
                type: internal
    ovs_version: "2.3.0"

Create the flat network on which you are going to launch the instances:

neutron net-create --tenant-id $TENANT_ID sharednet1 --shared \
--provider:network_type flat --provider:physical_network physnet1

Create the subnet on the newly created network:

neutron subnet-create sharednet1 $NETWORK_CIDR --name $SUBNET_NAME \
--ip-version=4 --gateway=$GATEWAY_IP --allocation-pool \
start=$START_IP,end=$END_IP --enable-dhcp

Configure the Bare Metal Service for Cleaning

If you configure Ironic to use cleaning (which is enabled by default), you will need to set the cleaning_network_uuid configuration option. Note the network UUID (the id field) of the network you created in NeutronFlatNetworking or another network you created for cleaning:
```
neutron net-list
```

Configure the cleaning network UUID via the cleaning_network_uuid option in the Ironic configuration file (/etc/ironic/ironic.conf). In the following, replace NETWORK_UUID with the UUID you noted in the previous step:

[neutron]
...

# UUID of the network to create Neutron ports on when booting
# to a ramdisk for cleaning/zapping using Neutron DHCP (string
# value)
#cleaning_network_uuid=<None>
cleaning_network_uuid = NETWORK_UUID

Restart the Bare Metal Service:

service ironic-api restart
service ironic-conductor restart

Image Requirements

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 Glance 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.

Note: tripleo-incubator provides a script to install all the dependencies for the disk-image-builder.
- Install diskimage-builder package (use virtualenv, if you don't want to install anything globally):
```
sudo pip install diskimage-builder
```
- Build the image your users will run (Ubuntu image has been taken as an example):
```
disk-image-create ubuntu baremetal dhcp-all-interfaces -o my-image
```
  The above command creates my-image.qcow2, my-image.vmlinuz and my-image.initrd files. If you want to use Fedora image, replace ubuntu with fedora in the above command. my-image.qcow2 is used while deploying the actual OS the users will run. The images my-image.vmlinuz and my-image.initrd are used for booting after deploying the bare metal with my-image.qcow2.
- Build the deploy image:
```
ramdisk-image-create ubuntu deploy-ironic \
-o my-deploy-ramdisk
```
  The above command creates my-deploy-ramdisk.kernel and my-deploy-ramdisk.initramfs files which are used initially for preparing the server (creating disk partitions) before the actual OS deploy. If you want to use a Fedora image, replace ubuntu with fedora in the above command.
Add the user images to glance

Load all the images created in the below steps into Glance, and note the glance image UUIDs for each one as it is generated.
- Add the kernel and ramdisk images to glance:
```
glance image-create --name my-kernel --is-public True \
--disk-format aki  < my-image.vmlinuz
```
  Store the image uuid obtained from the above step as $MY_VMLINUZ_UUID.
```
glance image-create --name my-image.initrd --is-public True \
--disk-format ari  < my-image.initrd
```
  Store the image UUID obtained from the above step as $MY_INITRD_UUID.
- Add the my-image to glance which is going to be the OS that the user is going to run. Also associate the above created images with this OS image. These two operations can be done by executing the following command:
```
glance image-create --name my-image --is-public True \
--disk-format qcow2 --container-format bare --property \
kernel_id=$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. An example is as follows:
```
glance image-create --name my-whole-disk-image --is-public True \
--disk-format qcow2 \
--container-format bare < my-whole-disk-image.qcow2
```
Add the deploy images to glance

Add the my-deploy-ramdisk.kernel and my-deploy-ramdisk.initramfs images to glance:
```
glance image-create --name deploy-vmlinuz --is-public True \
--disk-format aki < my-deploy-ramdisk.kernel
```
Store the image UUID obtained from the above step as $DEPLOY_VMLINUZ_UUID.
```
glance image-create --name deploy-initrd --is-public True \
--disk-format ari < my-deploy-ramdisk.initramfs
```
Store the image UUID obtained from the above step as $DEPLOY_INITRD_UUID.

Flavor Creation

You'll need to create a special Bare Metal flavor in Nova. The flavor is mapped to the bare metal server through the hardware specifications.

Change these to match your hardware:

RAM_MB=1024
CPU=2
DISK_GB=100
ARCH={i686|x86_64}

Create the baremetal flavor by executing the following command:
```
nova flavor-create my-baremetal-flavor auto $RAM_MB $DISK_GB $CPU
```
Note: You can replace auto with your own flavor id.
A flavor can include a set of key/value pairs called extra_specs. In case of Icehouse version of Ironic, you need to associate the deploy ramdisk and deploy kernel images to the flavor as flavor-keys. But in case of Juno and higher versions, this is deprecated. Because these may vary between nodes in a heterogeneous environment, the deploy kernel and ramdisk images should be associated with each node's driver_info.
- Icehouse version of Ironic:
```
nova flavor-key my-baremetal-flavor set \
cpu_arch=$ARCH \
"baremetal:deploy_kernel_id"=$DEPLOY_VMLINUZ_UUID \
"baremetal:deploy_ramdisk_id"=$DEPLOY_INITRD_UUID
```
- Juno and higher versions of Ironic:
```
nova flavor-key my-baremetal-flavor set cpu_arch=$ARCH
```
  Associate the deploy ramdisk and deploy kernel images each of your node's driver_info:
```
ironic node-update $NODE_UUID add \
driver_info/pxe_deploy_kernel=$DEPLOY_VMLINUZ_UUID \
driver_info/pxe_deploy_ramdisk=$DEPLOY_INITRD_UUID \
```

Setup the drivers for Bare Metal Service

PXE Setup

If you will be using PXE, it needs to be set up on the Bare Metal Service node(s) where ironic-conductor is running.

Make sure the tftp root directory exist and can be written to by the user the ironic-conductor is running as. For example:
```
sudo mkdir -p /tftpboot
sudo chown -R ironic /tftpboot
```

Install tftp server and the syslinux package with the PXE boot images:

Ubuntu: (Up to and including 14.04)
    sudo apt-get install tftpd-hpa syslinux-common syslinux

Ubuntu: (14.10 and after)
    sudo apt-get install tftpd-hpa syslinux-common pxelinux

Fedora/RHEL:
    sudo yum install tftp-server syslinux-tftpboot

Setup tftp server to serve /tftpboot.

Copy the PXE image to /tftpboot. The PXE image might be found at¹:

Ubuntu (Up to and including 14.04):
    sudo cp /usr/lib/syslinux/pxelinux.0 /tftpboot

Ubuntu (14.10 and after):
    sudo cp /usr/lib/PXELINUX/pxelinux.0 /tftpboot

If whole disk images need to be deployed via PXE-netboot, copy the chain.c32 image to /tftpboot to support it. The chain.c32 image might be found at:

Ubuntu (Up to and including 14.04):
    sudo cp /usr/lib/syslinux/chain.c32 /tftpboot

Ubuntu (14.10 and after):
    sudo cp /usr/lib/syslinux/modules/bios/chain.c32 /tftpboot

Fedora:
    sudo cp /boot/extlinux/chain.c32 /tftpboot

If the version of syslinux is greater than 4 we also need to make sure that we copy the library modules into the /tftpboot directory² ³:
```
Ubuntu:
    sudo cp /usr/lib/syslinux/modules/*/ldlinux.* /tftpboot
```

Create a map file in the tftp boot directory (/tftpboot):

echo 'r ^([^/]) /tftpboot/\1' > /tftpboot/map-file
echo 'r ^(/tftpboot/) /tftpboot/\2' >> /tftpboot/map-file

Enable tftp map file, modify /etc/xinetd.d/tftp as below and restart xinetd service:
```
server_args = -v -v -v -v -v --map-file /tftpboot/map-file /tftpboot
```

PXE UEFI Setup

If you want to deploy on a UEFI supported bare metal, perform these additional steps on the Ironic conductor node to configure PXE UEFI environment.

Download and untar the elilo bootloader version >= 3.16 from http://sourceforge.net/projects/elilo/:
```
sudo tar zxvf elilo-3.16-all.tar.gz
```
Copy the elilo boot loader image to /tftpboot directory:
```
sudo cp ./elilo-3.16-x86_64.efi /tftpboot/elilo.efi
```

Update the Ironic node with boot_mode capability in node's properties field:

ironic node-update <node-uuid> add properties/capabilities='boot_mode:uefi'

Make sure that bare metal node is configured to boot in UEFI boot mode and boot device is set to network/pxe.

NOTE: pxe_ilo driver supports automatic setting of UEFI boot mode and boot device on the baremetal node. So this step is not required for pxe_ilo driver.

For more information on configuring boot modes, refer boot_mode_support.

iPXE Setup

An alternative to PXE boot, iPXE was introduced in the Juno release (2014.2.0) of Ironic.

If you will be using iPXE to boot instead of PXE, iPXE needs to be set up on the Bare Metal Service node(s) where ironic-conductor is running.

Make sure these directories exist and can be written to by the user the ironic-conductor is running as. For example:
```
sudo mkdir -p /tftpboot
sudo mkdir -p /httpboot
sudo chown -R ironic /tftpboot
sudo chown -R ironic /httpboot
```

Create a map file in the tftp boot directory (/tftpboot):

echo 'r ^([^/]) /tftpboot/\1' > /tftpboot/map-file
echo 'r ^(/tftpboot/) /tftpboot/\2' >> /tftpboot/map-file

Set up TFTP and HTTP servers.

These servers should be running and configured to use the local /tftpboot and /httpboot directories respectively, as their root directories. (Setting up these servers is outside the scope of this install guide.)

These root directories need to be mounted locally to the ironic-conductor services, so that the services can access them.

The Bare Metal Service's configuration file (/etc/ironic/ironic.conf) should be edited accordingly to specify the TFTP and HTTP root directories and server addresses. For example:
```
[pxe]

# Ironic compute node's http root path. (string value)
http_root=/httpboot

# Ironic compute node's tftp root path. (string value)
tftp_root=/tftpboot

# IP address of Ironic compute node's tftp server. (string
# value)
tftp_server=192.168.0.2

# Ironic compute node's HTTP server URL. Example:
# http://192.1.2.3:8080 (string value)
http_url=http://192.168.0.2:8080
```

Install the iPXE package with the boot images:

Ubuntu:
    apt-get install ipxe

Fedora/RHEL:
    yum install ipxe-bootimgs

Copy the iPXE boot image (undionly.kpxe) to /tftpboot. The binary might be found at:

Ubuntu:
    cp /usr/lib/ipxe/undionly.kpxe /tftpboot

Fedora/RHEL:
    cp /usr/share/ipxe/undionly.kpxe /tftpboot

*Note: If the packaged version of the iPXE boot image doesn't
work for you or you want to build one from source take a look at
http://ipxe.org/download for more information on preparing iPXE image.*

Enable/Configure iPXE in the Bare Metal Service's configuration file (/etc/ironic/ironic.conf):

[pxe]

# Enable iPXE boot. (boolean value)
ipxe_enabled=True

# Neutron bootfile DHCP parameter. (string value)
pxe_bootfile_name=undionly.kpxe

# Template file for PXE configuration. (string value)
pxe_config_template=$pybasedir/drivers/modules/ipxe_config.template

Restart the ironic-conductor process:
```
service ironic-conductor restart
```

IPMI support

If using the IPMITool driver, the ipmitool command must be present on the service node(s) where ironic-conductor is running. On most distros, this is provided as part of the ipmitool package. Source code is available at http://ipmitool.sourceforge.net/

Note that certain distros, notably Mac OS X and SLES, install openipmi instead of ipmitool by default. THIS DRIVER IS NOT COMPATIBLE WITH openipmi AS IT RELIES ON ERROR HANDLING OPTIONS NOT PROVIDED BY THIS TOOL.

Check that you can connect to and authenticate with the IPMI controller in your bare metal server by using ipmitool:

ipmitool -I lanplus -H <ip-address> -U <username> -P <password> chassis power status

<ip-address> = The IP of the IPMI controller you want to access

Note:

This is not the bare metal server’s main IP. The IPMI controller should have it’s own unique IP.
In case the above command doesn't return the power status of the bare metal server, check for these:
- ipmitool is installed.
- The IPMI controller on your bare metal server is turned on.
- The IPMI controller credentials passed in the command are right.
- The conductor node has a route to the IPMI controller. This can be checked by just pinging the IPMI controller IP from the conductor node.

Note

If there are slow or unresponsive BMCs in the environment, the retry_timeout configuration option in the [ipmi] section may need to be lowered. The default is fairly conservative, as setting this timeout too low can cause older BMCs to crash and require a hard-reset.

Ironic supports sending IPMI sensor data to Ceilometer with pxe_ipmitool, pxe_ipminative, agent_ipmitool, agent_pyghmi, agent_ilo, iscsi_ilo, pxe_ilo, and with pxe_irmc driver starting from Kilo release. By default, support for sending IPMI sensor data to Ceilometer is disabled. If you want to enable it, you should make the following two changes in ironic.conf:

notification_driver = messaging in the DEFAULT section
send_sensor_data = true in the conductor section

If you want to customize the sensor types which will be sent to Ceilometer, change the send_sensor_data_types option. For example, the below settings will send Temperature,Fan,Voltage these three sensor types data to Ceilometer:

send_sensor_data_types=Temperature,Fan,Voltage

Else we use default value 'All' for all the sensor types which supported by Ceilometer, they are:

Temperature,Fan,Voltage,Current

Boot mode support

The following drivers support setting of boot mode (Legacy BIOS or UEFI).

pxe_ipmitool

The boot modes can be configured in Ironic in the following way:

When no boot mode setting is provided, these drivers default the boot_mode to Legacy BIOS.
Only one boot mode (either uefi or bios) can be configured for the node.
If the operator wants a node to boot always in uefi mode or bios mode, then they may use capabilities parameter within properties field of an Ironic node. The operator must manually set the appropriate boot mode on the bare metal node.

To configure a node in uefi mode, then set capabilities as below:
```
ironic node-update <node-uuid> add properties/capabilities='boot_mode:uefi'
```
Nodes having boot_mode set to uefi may be requested by adding an extra_spec to the Nova flavor:
```
nova flavor-key ironic-test-3 set capabilities:boot_mode="uefi"
nova boot --flavor ironic-test-3 --image test-image instance-1
```
If capabilities is used in extra_spec as above, Nova scheduler (ComputeCapabilitiesFilter) will match only Ironic nodes which have the boot_mode set appropriately in properties/capabilities. It will filter out rest of the nodes.

The above facility for matching in Nova can be used in heterogeneous environments where there is a mix of uefi and bios machines, and operator wants to provide a choice to the user regarding boot modes. If the flavor doesn't contain boot_mode and boot_mode is configured for Ironic nodes, then Nova scheduler will consider all nodes and user may get either bios or uefi machine.

Local boot with partition images

Starting with the Kilo release, Ironic supports local boot with partition images, meaning that after the deployment the node's subsequent reboots won't happen via PXE or Virtual Media. Instead, it will boot from a local boot loader installed on the disk.

It's important to note that in order for this to work the image being deployed with Ironic must contain grub2 installed within it.

Enabling the local boot is different when Ironic is used with Nova and without it. The following sections will describe both methods.

Note

The local boot feature is dependent upon a updated deploy ramdisk built with diskimage-builder version >= 0.1.42 or ironic-python-agent in the kilo-era.

Enabling local boot with Nova

To enable local boot we need to set a capability on the Ironic node, e.g:

ironic node-update <node-uuid> add properties/capabilities="boot_option:local"

Nodes having boot_option set to local may be requested by adding an extra_spec to the Nova flavor, e.g:

nova flavor-key baremetal set capabilities:boot_option="local"

Note

If the node is configured to use UEFI, Ironic will create an EFI partition on the disk and switch the partition table format to gpt. The EFI partition will be used later by the boot loader (which is installed from the deploy ramdisk).

Enabling local boot without Nova

Since adding capabilities to the node's properties is only used by the Nova scheduler to perform more advanced scheduling of instances, we need a way to enable local boot when Nova is not present. To do that we can simply specify the capability via the instance_info attribute of the node, e.g:

ironic node-update <node-uuid> add instance_info/capabilities='{"boot_option": "local"}'

Enrollment

After all services have been properly configured, you should enroll your hardware with Ironic, and confirm that the Compute service sees the available hardware.

Note

When enrolling Nodes with Ironic, note that the Compute service will not be immediately notified of the new resources. Nova's resource tracker syncs periodically, and so any changes made directly to Ironic's resources will become visible in Nova only after the next run of that periodic task. More information is in the Troubleshooting section below.

Note

Any Ironic Node that is visible to Nova may have a workload scheduled to it, if both the power and deploy interfaces pass the validate check. If you wish to exclude a Node from Nova's scheduler, for instance so that you can perform maintenance on it, you can set the Node to "maintenance" mode. For more information see the Troubleshooting section below.

Some steps are shown separately for illustration purposes, and may be combined if desired.

Create a Node in Ironic. At minimum, you must specify the driver name (eg, "pxe_ipmitool"). This will return the node UUID:

ironic node-create -d pxe_ipmitool
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | dfc6189f-ad83-4261-9bda-b27258eb1987 |
| driver_info  | {}                                   |
| extra        | {}                                   |
| driver       | pxe_ipmitool                         |
| chassis_uuid |                                      |
| properties   | {}                                   |
+--------------+--------------------------------------+

Update the Node driver_info so that Ironic can manage the node. Different drivers may require different information about the node. You can determine this with the driver-properties command, as follows:

ironic driver-properties pxe_ipmitool
+----------------------+-------------------------------------------------------------------------------------------------------------+
| Property             | Description                                                                                                 |
+----------------------+-------------------------------------------------------------------------------------------------------------+
| ipmi_address         | IP address or hostname of the node. Required.                                                               |
| ipmi_password        | password. Optional.                                                                                         |
| ipmi_username        | username; default is NULL user. Optional.                                                                   |
| ...                  | ...                                                                                                         |
| pxe_deploy_kernel    | UUID (from Glance) of the deployment kernel. Required.                                                      |
| pxe_deploy_ramdisk   | UUID (from Glance) of the ramdisk that is mounted at boot time. Required.                                   |
+----------------------+-------------------------------------------------------------------------------------------------------------+

ironic node-update $NODE_UUID add \
driver_info/ipmi_username=$USER \
driver_info/ipmi_password=$PASS \
driver_info/ipmi_address=$ADDRESS

Note that you may also specify all driver_info parameters during node-create by passing the -i option multiple times.

Update the Node's properties to match the baremetal flavor you created earlier:
```
ironic node-update $NODE_UUID add \
properties/cpus=$CPU \
properties/memory_mb=$RAM_MB \
properties/local_gb=$DISK_GB \
properties/cpu_arch=$ARCH
```
As above, these can also be specified at node creation by passing the -p option to node-create multiple times.
If you wish to perform more advanced scheduling of instances based on hardware capabilities, you may add metadata to each Node that will be exposed to the Nova Scheduler (see: ComputeCapabilitiesFilter). A full explanation of this is outside of the scope of this document. It can be done through the special capabilities member of Node properties:
```
ironic node-update $NODE_UUID add \
properties/capabilities=key1:val1,key2:val2
```
As mentioned in the Flavor Creation section, if using the Juno or later release of Ironic, you should specify a deploy kernel and ramdisk which correspond to the Node's driver, eg:
```
ironic node-update $NODE_UUID add \
driver_info/pxe_deploy_kernel=$DEPLOY_VMLINUZ_UUID \
driver_info/pxe_deploy_ramdisk=$DEPLOY_INITRD_UUID \
```
You must also inform Ironic of the Network Interface Cards which are part of the Node by creating a Port with each NIC's MAC address. These MAC addresses are passed to Neutron during instance provisioning and used to configure the network appropriately:
```
ironic port-create -n $NODE_UUID -a $MAC_ADDRESS
```

To check if Ironic has the minimum information necessary for a Node's driver to function, you may validate it:

ironic node-validate $NODE_UUID

+------------+--------+--------+
| Interface  | Result | Reason |
+------------+--------+--------+
| console    | True   |        |
| deploy     | True   |        |
| management | True   |        |
| power      | True   |        |
+------------+--------+--------+

If the Node fails validation, each driver will return information as to why it failed:

ironic node-validate $NODE_UUID

+------------+--------+-------------------------------------------------------------------------------------------------------------------------------------+
| Interface  | Result | Reason                                                                                                                              |
+------------+--------+-------------------------------------------------------------------------------------------------------------------------------------+
| console    | None   | not supported                                                                                                                       |
| deploy     | False  | Cannot validate iSCSI deploy. Some parameters were missing in node's instance_info. Missing are: ['root_gb', 'image_source']        |
| management | False  | Missing the following IPMI credentials in node's driver_info: ['ipmi_address'].                                                     |
| power      | False  | Missing the following IPMI credentials in node's driver_info: ['ipmi_address'].                                                     |
+------------+--------+-------------------------------------------------------------------------------------------------------------------------------------+

Hardware Inspection

Starting with Kilo release Ironic supports hardware inspection that simplifies enrolling nodes. Inspection allows Ironic to discover required node properties once required driver_info fields (e.g. IPMI credentials) are set by an operator. Inspection will also create the ironic ports for the discovered ethernet MACs. Operators will have to manually delete the ironic ports for which physical media is not connected. This is required due to the bug 1405131.

There are two kinds of inspection supported by Ironic:

Out-of-band inspection is currently implemented by iLO drivers, listed at ilo.
In-band inspection is performed by utilizing the ironic-discoverd project. This is supported by the following drivers:
```
pxe_drac
pxe_ipmitool
pxe_ipminative
pxe_ssh
```

As of Kilo release this feature needs to be explicitly enabled in the configuration by setting enabled = True in [discoverd] section. You must additionally install ironic-discoverd to use this functionality. You must set service_url if the ironic-discoverd service is being run on a separate host from the ironic-conductor service, or is using non-standard port.

In order to ensure that ports in Ironic are synchronized with NIC ports on the node, the following settings in the ironic-discoverd configuration file must be set:
[discoverd]
add_ports = all
keep_ports = present
Note: It will require ironic-discoverd of version 1.1.0 or higher.

Inspection can be initiated using node-set-provision-state. The node should be in MANAGEABLE state before inspection is initiated.

Move node to manageable state:

ironic node-set-provision-state <node_UUID> manage

Initiate inspection:

ironic node-set-provision-state <node_UUID> inspect

Note

The above commands require the python-ironicclient to be version 0.5.0 or greater.

Specifying the disk for deployment

Starting with the Kilo release, Ironic supports passing hints to the deploy ramdisk about which disk it should pick for the deployment. In Linux when a server has more than one SATA, SCSI or IDE disk controller, the order in which their corresponding device nodes are added is arbitrary [link], resulting in devices like /dev/sda and /dev/sdb to switch around between reboots. Therefore, to guarantee that a specific disk is always chosen for the deployment, Ironic introduced root device hints.

The list of support hints is:

model (STRING): device identifier
vendor (STRING): device vendor
serial (STRING): disk serial number
wwn (STRING): unique storage identifier
size (INT): size of the device in GiB

To associate one or more hints with a node, update the node's properties with a root_device key, e.g:

ironic node-update <node-uuid> add properties/root_device='{"wwn": "0x4000cca77fc4dba1"}'

That will guarantee that Ironic will pick the disk device that has the wwn equal to the specified wwn value, or fail the deployment if it can not be found.

Note

If multiple hints are specified, a device must satisfy all the hints.

Using Ironic as a standalone service

Starting with Kilo release, it's possible to use Ironic without other OpenStack services.

You should make the following changes to /etc/ironic/ironic.conf:

To disable usage of Keystone tokens:
```
[DEFAULT]
...
auth_strategy=none
```
If you want to disable Neutron, you should have your network pre-configured to serve DHCP and TFTP for machines that you're deploying. To disable it, change the following lines:
```
[dhcp]
...
dhcp_provider=none
```
Note

If you disabled Neutron and driver that you use is supported by at most one conductor, PXE boot will still work for your nodes without any manual config editing. This is because you know all the DHCP options that will be used for deployment and can set up your DHCP server appropriately.

If you have multiple conductors per driver, it would be better to use Neutron since it will do all the dynamically changing configurations for you.

If you don't use Glance, it's possible to provide images to Ironic via hrefs.

Note

At the moment, only two types of hrefs are acceptable instead of Glance UUIDs: HTTP(S) hrefs (e.g. "http://my.server.net/images/img") and file hrefs (file:///images/img).

There are however some limitations for different drivers:

If you're using one of the drivers that use agent deploy method (namely, agent_ilo, agent_ipmitool, agent_pyghmi, agent_ssh or agent_vbox) you have to know MD5 checksum for your instance image. To compute it, you can use the following command:
```
md5sum image.qcow2
ed82def8730f394fb85aef8a208635f6  image.qcow2
```
Apart from that, because of the way the agent deploy method works, image hrefs can use only HTTP(S) protocol.
If you're using iscsi_ilo or agent_ilo driver, Swift service is required, as these drivers need to store floppy image that is used to pass parameters to deployment iso. For this method also only HTTP(S) hrefs are acceptable, as HP iLO servers cannot attach other types of hrefs as virtual media.
Other drivers use PXE deploy method and there are no special requirements in this case.

Steps to start a deployment are pretty similar to those when using Nova:

Create a Node in Ironic. At minimum, you must specify the driver name (eg, "pxe_ipmitool"). You can also specify all the required driver parameters in one command. This will return the node UUID:

ironic node-create -d pxe_ipmitool -i ipmi_address=ipmi.server.net \
-i ipmi_username=user -i ipmi_password=pass \
-i pxe_deploy_kernel=file:///images/deploy.vmlinuz \
-i pxe_deploy_ramdisk=http://my.server.net/images/deploy.ramdisk

+--------------+--------------------------------------------------------------------------+
| Property     | Value                                                                    |
+--------------+--------------------------------------------------------------------------+
| uuid         | be94df40-b80a-4f63-b92b-e9368ee8d14c                                     |
| driver_info  | {u'pxe_deploy_ramdisk': u'http://my.server.net/images/deploy.ramdisk',   |
|              | u'pxe_deploy_kernel': u'file:///images/deploy.vmlinuz', u'ipmi_address': |
|              | u'ipmi.server.net', u'ipmi_username': u'user', u'ipmi_password':         |
|              | u'******'}                                                               |
| extra        | {}                                                                       |
| driver       | pxe_ipmitool                                                             |
| chassis_uuid |                                                                          |
| properties   | {}                                                                       |
+--------------+--------------------------------------------------------------------------+

Note that here pxe_deploy_kernel and pxe_deploy_ramdisk contain links to images instead of Glance UUIDs.

As in case of Nova, you can also provide capabilities to node properties, but they will be used only by Ironic (e.g. boot mode). Although you don't need to add properties like memory_mb, cpus etc. as Ironic will require UUID of a node you're going to deploy.
Then create a port to inform Ironic of the Network Interface Cards which are part of the Node by creating a Port with each NIC's MAC address. In this case, they're used for naming of PXE configs for a node:
```
ironic port-create -n $NODE_UUID -a $MAC_ADDRESS
```
As there is no Nova flavor and instance image is not provided with nova boot command, you also need to specify some fields in instance_info. For PXE deployment, they are image_source, kernel, ramdisk, root_gb:
```
ironic node-update $NODE_UUID add instance_info/image_source=$IMG \
instance_info/kernel=$KERNEL instance_info/ramdisk=$RAMDISK \
instance_info/root_gb=10
```
Here $IMG, $KERNEL, $RAMDISK can also be HTTP(S) or file hrefs. For agent drivers, you don't need to specify kernel and ramdisk, but MD5 checksum of instance image is required:
```
ironic node-update $NODE_UUID add instance_info/image_checksum=$MD5HASH
```

Validate that all parameters are correct:

ironic node-validate $NODE_UUID

+------------+--------+----------------------------------------------------------------+
| Interface  | Result | Reason                                                         |
+------------+--------+----------------------------------------------------------------+
| console    | False  | Missing 'ipmi_terminal_port' parameter in node's driver_info.  |
| deploy     | True   |                                                                |
| management | True   |                                                                |
| power      | True   |                                                                |
+------------+--------+----------------------------------------------------------------+

Now you can start the deployment, just run:
```
ironic node-set-provision-state $NODE_UUID active
```
You can manage provisioning by issuing this command. Valid provision states are active, rebuild and deleted.

For iLO drivers, fields that should be provided are:

ilo_deploy_iso under driver_info;
ilo_boot_iso, image_source, root_gb under instance_info.

Note

There is one limitation in this method - Ironic is not tracking changes of content under hrefs that are specified. I.e., if the content under "http://my.server.net/images/deploy.ramdisk" changes, Ironic does not know about that and does not redownload the content.

Enabling local boot without Nova

Enabling the configuration drive (configdrive)

Starting with the Kilo release, Ironic supports exposing a configuration drive image to the instances.

The configuration drive is usually used in conjunction with Nova, but Ironic also offers a standalone way of using it. The following sections will describe both methods.

When used with Nova

To enable the configuration drive when deploying an instance, pass --config-drive true parameter to the nova boot command, e.g:

nova boot --config-drive true --flavor baremetal --image test-image instance-1

It's also possible to enable the configuration drive automatically on all instances by configuring the Nova Compute service to always create a configuration drive by setting the following option in the /etc/nova/nova.conf file, e.g:

[DEFAULT]
...

force_config_drive=always

When used standalone

When used without Nova, the operator needs to create a configuration drive and provide the file or HTTP URL to Ironic.

For the format of the configuration drive, Ironic expects a gzipped and base64 encoded ISO 9660⁴ file with a config-2 label. The Ironic client can generate a configuration drive in the expected format. Just pass a directory path containing the files that will be injected into it via the --config-drive parameter of the node-set-provision-state command, e.g:

ironic node-set-provision-state --config-drive /dir/configdrive_files $node_identifier active

Accessing the configuration drive data

When the configuration drive is enabled, Ironic will create a partition on the instance disk and write the configuration drive image onto it. The configuration drive must be mounted before use. This is performed automatically by many tools, such as cloud-init and cloudbase-init. To mount it manually on a Linux distribution that supports accessing devices by labels, simply run the following:

mkdir -p /mnt/config
mount /dev/disk/by-label/config-2 /mnt/config

If the guest OS doesn't support accessing devices by labels, you can use other tools such as blkid to identify which device corresponds to the configuration drive and mount it, e.g:

CONFIG_DEV=$(blkid -t LABEL="config-2" -odevice)
mkdir -p /mnt/config
mount $CONFIG_DEV /mnt/config

Cloud-init integration

The configuration drive can be especially useful when used with cloud-init [link], but in order to use it we should follow some rules:

Cloud-init expects a specific format to the data. For more information about the expected file layout see [link].
Since Ironic uses a disk partition as the configuration drive, it will only work with cloud-init version >= 0.7.5 [link].
Cloud-init has a collection of data source modules, so when building the image with disk-image-builder we have to define DIB_CLOUD_INIT_DATASOURCES environment variable and set the appropriate sources to enable the configuration drive, e.g:
```
DIB_CLOUD_INIT_DATASOURCES="ConfigDrive, OpenStack" disk-image-create -o fedora-cloud-image fedora baremetal
```
See [link] for more information.

Troubleshooting

Once all the services are running and configured properly, and a Node is enrolled with Ironic, the Nova Compute service should detect the Node as an available resource and expose it to the scheduler.

Note

There is a delay, and it may take up to a minute (one periodic task cycle) for Nova to recognize any changes in Ironic's resources (both additions and deletions).

In addition to watching nova-compute log files, you can see the available resources by looking at the list of Nova hypervisors. The resources reported therein should match the Ironic Node properties, and the Nova Flavor.

Here is an example set of commands to compare the resources in Nova and Ironic:

$ ironic node-list

If you need to take a Node out of the resource pool and prevent Nova from placing a tenant instance upon it, you can mark the Node as in “maintenance” mode with the following command. This also prevents Ironic from executing periodic tasks which might affect the node, until maintenance mode is disabled:

$ ironic node-set-maintenance $NODE_UUID on

On Fedora/RHEL the syslinux-tftpboot package already install the library modules and PXE image at /tftpboot. If the TFTP server is configured to listen to a different directory you should copy the contents of /tftpboot to the configured directory↩︎

A config drive could also be a data block with a VFAT filesystem on it instead of ISO 9660. But it's unlikely that it would be needed since ISO 9660 is widely supported across operating systems.↩︎
