I have an inventory of hosts that defines "my_groups" hash:
my_groups:
group1=val1
group2=val2
...
Note - it's a dynamic inventory which in fact produces valid JSON that
works otherwise.
Then I try to use it to auto-populate groups via:
- hosts: all
tasks:
- debug: var=hostvars[inventory_hostname]['my_groups'].keys()
- set_fact: my_group_list="{{
hostvars[inventory_hostname]['my_groups'].keys() }}"
when: hostvars[inventory_hostname].my_groups is defined
- debug: var=my_group_list
- group_by: key={{ item }}_group
with_items: hostvars[inventory_hostname].my_group_list
when: my_group_list is defined
and receive lovely:
...
TASK: [group_by key={{ item }}_group]
*****************************************
fatal: [moo.foo.com] => with_items expects a list or a set
...
even though last debug confirms that my_group_list is a proper list. When I
used "my_group_list" instead - it acted as if "my_group_list" was the item
to iterate over rather than variable:
TASK: [group_by key={{ item }}_group]
*****************************************
<moo.foo.com> ESTABLISH CONNECTION FOR USER: root
created 'group_by' ActionModule: key=my_group_list_group
changed: [moo.foo.com] => (item=my_group_list) => {"changed": true,
"groups": {"my_group_list_group": ["moo.foo.com", "bar.foo.com"]}, "item":
"my_group_list"}
Am I doing something wrong or am I facing a bug?
