Ironic/TripleO

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 thru.
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:
Please follow TripleO's Devtest-Doc up to the devtest_undercloud section.
Build undercloud containing Ironic
We need to modify step #1 of devtest_undercloud-walkthru to include the Ironic services, and to switch Nova from using the nova.virt.baremetal driver to instead use the nova.virt.ironic driver.
# Note that rev 21 was current at the time of this writing. You may need to update this revision number NOVA_PATCH_REV=21 cd $TRIPLEO_ROOT export UNDERCLOUD_DIB_EXTRA_ARGS="nova-ironic" export DIB_REPOLOCATION_nova=https://review.openstack.org/openstack/nova export DIB_REPOREF_nova=refs/changes/28/51328/$NOVA_PATCH_REV
Proceed until step #3 of devtest_undercloud-walkthru.
Heat template
Instead of building the undercloud-vm.yaml file, we want to build the undercloud-vm-ironic.yaml file:
make -C $TRIPLEO_ROOT/tripleo-heat-templates undercloud-vm-ironic.yaml
This template requires slightly different parameters, so use this command to deploy your undercloud:
heat stack-create -f $TRIPLEO_ROOT/tripleo-heat-templates/undercloud-vm-ironic.yaml \
-P "AdminToken=${UNDERCLOUD_ADMIN_TOKEN};\
AdminPassword=${UNDERCLOUD_ADMIN_PASSWORD};\
GlancePassword=${UNDERCLOUD_GLANCE_PASSWORD};\
HeatPassword=${UNDERCLOUD_HEAT_PASSWORD};\
NeutronPassword=${UNDERCLOUD_NEUTRON_PASSWORD};\
NovaPassword=${UNDERCLOUD_NOVA_PASSWORD};\
BaremetalArch=${NODE_ARCH};\
IronicPassword=${UNDERCLOUD_IRONIC_PASSWORD}" \
undercloud
Continue devtest_undercloud-walkthru
Continue to follow the devtest_undercloud-walkthru up through step #9.
Register the Ironic service
After step #9, register the Ironic service with keystone.
PASSWORD=$UNDERCLOUD_IRONIC_PASSWORD register-endpoint -r "regionOne" -d "Ironic Service" ironic baremetal http://$UNDERCLOUD_IP:6385
In devtest_undercloud-walkthru's step #10, nodes are registered to the undercloud's nova-baremetal and not Ironic. Instead of that, we'll create a 'baremetal' node and register it with ironic, via the undercloud.
Allow Ironic's SSH driver to connect to your local machine:
ssh heat-admin@$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]
