Host classification problem

Hi all,

I am having a problem with host classification. In my hosts file i have a “nodejs:children” group with application “foo”. “foo” has server-a. In site.yml I use hosts: nodejs:&{{ application }} and assign a role. This works well with multiple applications until the same server is configured in multiple groups. Then multiple roles are applied. I would expect only 1 role applied. Any idea what is going wrong? Here is the relevant files:

hosts:


[nodejs:children]
foo
[java:children]
bar
[foo]
localhost
[bar]
localhost

site.yml:


---

- name: deploy nodejs app

hosts: nodejs:&{{ application }}

roles:

- nodejs

- name: deploy java app

hosts: java:&{{ application }}

roles:

- java

command:


ansible-playbook site.yml -i hosts --check -e 'application=foo'

Thanks,
Jan

The hostnames in inventory are unique, if you define a host in more
than one place, it is the same host.
