one of the other things you can do is use the groups key in the jinja template to add in config for specific host groups: eg: {% if ansible_fqdn in groups['compute_group_a'] %} some_var = "foo" {% elif ansible_fqdn in groups['compute_group_b'] %} other_var = "boo" {% endif %} not quite as clean as having a merge_configs keyed to the group but in my experience you aren't normally changing a tonne of values for a service anyways so it's pretty manageable. ________________________________ From: Nguyễn Hữu Khôi <nguyenhuukhoinw@gmail.com> Sent: 21 August 2023 11:57 To: Michal Arbet <michal.arbet@ultimum.io> Cc: OpenStack Discuss <openstack-discuss@lists.openstack.org> Subject: Re: [openstack][kolla-ansible]about group node config overwrite CAUTION: This email originates from outside THG ________________________________ Thanks much, I will try if it is ok, I will submit it.

I want to ask if we can overwrite config for a group of nodes. For example, compute01 >> compute10 will have the same nova configuration compute11 >> compute20 will have the same nova configuration. It will be very nice if we support this way. Thank you. Regards Nguyen Huu Khoi
