Using Ironic with TripleO

In this section, we will go over how to set up Ironic within the TripleO enviroment.

Note: TripleO is under rapid development and may invalidate this walk-through.

If not familiar with TripleO and / or have not used the DiskImage-Builder (DIB) tool before, please read and familiarize yourself with the TripleO story. Here are some good starting points:

Switch the undercloud to build with Ironic by doing:

 export USE_IRONIC=1

Then, follow TripleO's Devtest-Doc up to the devtest_undercloud section.

Register the Ironic service

In devtest_undercloud-walkthru's step #10, nodes are registered to the undercloud's nova-baremetal and not Ironic. Instead of that, we'll create a 'baremetal' node and register it with ironic, via the undercloud.

Allow Ironic's SSH driver to connect to your local machine:

ssh heat-admin@$UNDERCLOUD_IP "cat /opt/stack/boot-stack/ironic-ssh-power-key.pub" >> ~/.ssh/authorized_keys

Copy the Ironic API credentials to your local machine:

ssh heat-admin@$UNDERCLOUD_IP -- 'sudo cat /root/stackrc' > $TRIPLEO_ROOT/tripleo-incubator/ironicrc
sed -i "s/localhost/$UNDERCLOUD_IP/" $TRIPLEO_ROOT/tripleo-incubator/ironicrc
source $TRIPLEO_ROOT/tripleo-incubator/ironicrc

Create an emulated baremetal node

This will create a 'baremetal' node:

export UNDERCLOUD_MAC=$(create-nodes $NODE_CPU $NODE_MEM $NODE_DISK $NODE_ARCH 1)

Use the ironic client to enroll the baremetal node:

HOST_IP=$(ip addr show virbr0 | grep inet | awk '{print $2}' | sed 's/\/[0-9]*//')
CHASSIS=$(ironic chassis-create -d TestChassis | grep uuid | awk '{print $4}')
NODE=$(ironic node-create -c $CHASSIS -d pxe_ssh | grep ' uuid ' | awk '{print $4}')
ironic port-create -n $NODE -a $UNDERCLOUD_MAC 
ironic node-update $NODE add \
 driver_info/ssh_virt_type=virsh \
 driver_info/ssh_address=$HOST_IP \
 driver_info/ssh_key_filename=/opt/stack/boot-stack/ironic-ssh-power-key \
 driver_info/ssh_username=$(whoami)

Confirm everything is enrolled and correct:

ironic node-show $NODE

You can now control the power state of this node with this command:

ironic node-set-power-state $NODE [on|off|reboot]
