Dear list,

I am experimenting with kayobe to deploy a test installation of OpenStack wallaby. You can find my configuration here:

https://github.com/openstack/kayobe-config/compare/stable/wallaby...holtgrew...

I am following the kayobe documentation and have successfully setup a controller and a seed node.

I am at the point where I have the nodes configured and they show up in bifrost baremetal node list. I can control them via IPMI/iDRAC/RedFish and boot them into the IPA image and the nodes can be inspected and actually go into the "manageable" status. kayobe is capable of using the inspection results and assigning the root device, so far, so good.

I don't know whether my network configuration is good. I want to pin the IPs of stack-1 to stack-4 and the names resolve the correct IP addresses throughout my network.

Below are some more details. In summary, I have trouble because `kayobe overcloud provision` makes my 4 overcloud bare metal host boot into IPA with DHCP enabled and they get the same IPs assigned that were given to them earlier in inspection. This means that the overcloud provision command cannot SSH into the nodes because it knows them by the wrong IPs.

I must be really missing something here. What is it?

Hi Manuel. Bifrost will assign IPs from its IP address pool to the machines during inspection and provisioning. IPA will use these addresses. Once provisioning is complete, the machines should boot up into a CentOS image, using the IPs you have allocated. These are statically configured via a configdrive, which is installed during provisioning. If the node stays running IPA, then something is going wrong with provisioning. Mark

Below are more details.

Here is what kayobe pulled from the bifrost inspection (I believe).

# cat etc/kayobe/inventory/overcloud [controllers] stack-1 ipmi_address=172.16.66.41 bmc_type=idrac stack-2 ipmi_address=172.16.66.42 bmc_type=idrac stack-3 ipmi_address=172.16.66.43 bmc_type=idrac stack-4 ipmi_address=172.16.66.44 bmc_type=idrac

The IPs are also fixed here

# etc/kayobe/network-allocation.yml compute_net_ips: stack-1: 172.16.32.11 stack-2: 172.16.32.12 stack-3: 172.16.32.13 stack-4: 172.16.32.14 stack-seed: 172.16.32.6

However, I thought I had to provide allocation ranges for DHCP for getting introspection to work.

Thus, I have the following

# etc/kayobe/networks.yml compute_net_cidr: 172.16.32.0/19 compute_net_gateway: 172.16.32.1 compute_net_vip_address: 172.16.32.2 compute_net_allocation_pool_start: 172.16.32.101 compute_net_allocation_pool_end: 172.16.32.200 compute_net_inspection_allocation_pool_start: 172.16.32.201 compute_net_inspection_allocation_pool_end: 172.16.32.250

This leads to the following dnsmasq leases in the bifrost host.

# cat /var/lib/dnsmasq/dnsmasq.leases 1634187260 REDACTED 172.16.32.215 * REDACTED 1634187271 REDACTED 172.16.32.243 * REDACTED 1634187257 REDACTED 172.16.32.207 * REDACTED 1634187258 REDACTED 172.16.32.218 * REDACTED

What am I missing?

Best wishes, Manuel
