Open Stack

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.

I will do it. I still hope that will be official feature.

Hello,

It's Ansible so create your special group, change inventory and place your group related variables to group_vars/yourgroup.yml and in config overrides you can use your group related values.

I think this should work

Hello Koller.

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
