Kolla-ansible won't lookup config files based on group names, but the
content of those files is templated. See the examples here:

Thank you mark, i think you found my typo :)  that was it.

How do i group nodes and pass configuration to specific group like.

for example i have GPU and IB compute nodes. i want to group them so i

can push out to config to GPU group related GPU and IB (infiniband)

related IB config

[gpu]

1.1.1.1

2.2.2.2

3.3.3.3

[ib]

4.4.4.4

5.5.5.5

6.6.6.6

[compute:children]

gpu

ib

Can i apply config like following for group related?  what is the best

way to handle groups in kolla-ansible?

/etc/kolla/config/nova/gpu/nova.conf

/etc/kolla/config/nova/ib/nova.conf

Folks,

I have a working kolla-ansible environment and now I want to push out

some nova custom changes to specific compute nodes and I am trying the

following override but somehow it doesn't work for me.

Ansible inventory file multinode

[control]

192.168.75.141 ansible_ssh_private_key_file=/root/.ssh/nodes_ssh_key

192.168.75.142 ansible_ssh_private_key_file=/root/.ssh/nodes_ssh_key

192.168.75.143 ansible_ssh_private_key_file=/root/.ssh/nodes_ssh_key

[compute]

192.168.75.[144:175] ansible_ssh_private_key_file=/root/.ssh/nodes_ssh_key

FYI you can use hostnames but still use IPs to connect:

myhost ansible_host=1.2.3.4

I want to change some option on 192.168.75.199 compute server, I don't

have compute name in inventory so i am using IP address for override

but somehow that doesn't work

/etc/kolla/config/nova/192.168.75.199/nova.conf

That is the correct path, when using the default config location.

Sanity check: .199 isn't in the above inventory.

I have tried the following to use hypervisor hostname but that doesn't

work. What am I doing wrong here?

/etc/kolla/config/nova/COMP01.local/nova.conf

We use inventory_hostname to determine the path, so it will be

whatever you use as the name in your inventory. In your example it's

IPs.

Following works for me but they are for global not for specific nodes.

How do i override specific node file?

/etc/kolla/config/nova/nova-compute.conf
