Put the data into dictionaries, e.g.
shell> cat group_vars.yml
G1:
groupname: A
G2:
groupname: B
G3:
groupname: C
G4:
groupname: D
Include the variables into a dictionary and extract the keys, e.g.
- include_vars:
file: group_vars.yml
name: d1
- debug:
msg: "{{ item.groupname }}"
loop: "{{ groups_name|
default([])|
map('extract', d1)|
list }}"
The command
shell> ansible-playbook pb.yml -e '{"groups_name": ["G1","G2"]}'
should give
msg: A
msg: B
If you have to keep the data in the lists select the the first item
msg: "{{ item.0.groupname }}"
