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 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 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 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
