Hi,

I'm trying to deploy an overcloud using tripleo with pre provisioned nodes. My configuration is quite simple:

- 1 controller and 1 compute nodes on which I already installed CentOS 8.2

- Both nodes have a dedicated idrac interface with an ip in 192.168.199.0/24. Please note that this interface is not visible with "ip a" or "ifconfig". It's a dedicated IDRAC interface

- Both nodes have a NIC configured in the subnet 192.168.199.0/24 (192.168.199.200 and 192.168.199.201)

- Undercloud uses 192.168.199.0/24 as pxe/provisioning network (but I don't need provisioning)

Question: should I import nodes with "openstack overcloud node import nodes.yaml" even if I don't need the provisioning step?

Furthermore, on the undercloud I created one file:

/home/stack/templates/node-info.yaml with the following content

parameter_defaults:
  OvercloudControllerFlavor: control
  OvercloudComputeFlavor: compute
  ControllerCount: 1
  ComputeCount: 1

 

Question: How can I specify that "node X with ip Y should be used as a controller and node Z with ip K should be used as a compute"??

With pre-provisioned nodes (DeployedServer), you would need to specify  HostnameMap and DeployedServerPortMap parameters that would map the pre-provisioned hosts and ctlplane ips.

Please check documentation[1] for more details.

Should I set the property with the following command?

openstack baremetal node set --property capabilities='profile:control' controller1

Thank you,

Marco
