Using Ironic client with agent_ipmitool driver
作者：互联网
Lets see how to deploy a server using ironic. To do that we are going to define those variables:
# Ironic client variables
export IRONIC_URL=http://IRONIC-API-SERVER:6385/
export OS_AUTH_TOKEN=" "
# Baremetal server variables
NAME=test1
# PXE NIC address
MAC=00:25:90:8f:51:a0
# IPMI address, we asume ADMIN/ADMIN as user/password
IPMI=10.0.1.100
# UUID of the chassis (optinal, remove the references in the commands)
CHASSIS=0cdaf66c-3d51-40fa-ba00-57dfdc9e5666
Now is possible to define the new host in Ironic. In this case we are going to deploy Ubuntu on a server using Config-Drive to pass the host configuration.
# Define the new baremetal host
ironic node-create -c $CHASSIS -n $NAME
-d agent_ipmitool \
-i ipmi_address=$IPMI \
-i ipmi_username=ADMIN \
-i ipmi_password=ADMIN \
-i deploy_kernel=file:///var/lib/ironic/http/deploy/coreos_production_pxe.vmlinuz \
-i deploy_ramdisk=file:///var/lib/ironic/http/deploy/coreos_production_pxe_image-oem.cpio.gz

Note that the file references are on the Ironic server, not on the client, because those images are going to be used for PXE.
To see all available images, go to: http://IRONIC-API-SERVER:80/
# Ironic needs the MD5 checksum of the image to check that it is not corrupted during the copy process
MD5=45e1ecce11c3c7d6e40baba8e91eadef
# Define the final image to deploy on the server

Now is time to validate the node:
# Validate the node
ironic node-validate $UUID
+------------+--------+---------------------------------------------------------------+
| Interface | Result | Reason |
+------------+--------+---------------------------------------------------------------+
| console | False | Missing 'ipmi_terminal_port' parameter in node's driver_info. |
| deploy | True | |
| inspect | None | not supported |
| management | True | |
| power | True | |
+------------+--------+---------------------------------------------------------------+
Node validation is just a process to check that the node has defined all the variables for all the steps (and also if the images are available). In this case it complains about a missing parameter for the console, but unfortunately our hardware does not support console over UDP (ipmi_terminal_port). Also, the IPA deploy image has no inspect support, so hardware inspection is not available (for the moment).
To deploy the node using Config-Drive folder (see here how to create it):
ironic node-set-provision-state --config-drive /tmp/$NAME $NAME active

So, now the node has been deployed, by using the ip address you have specified on the Config-Drive configuration and the ssh-key you should also have provided, be able to login in the server!
