Kai - Thank you very much. Everything you mentioned was exactly right.
Helped me learn a thing or two about proper syntax...and reminding me not
to code too late into the evening. haha.
Final Playbook:
---
- name: Target Host
hosts: "{{ target }}"
tasks:
- name: Register foo
command: 'echo Hello World'
register: foo
- name: Different Host
hosts: ptl01a0fap005
tasks:
# - debug: var=hostvars[groups['{{ target }}'][0]]['foo']['stdout']
- debug: var=hostvars[groups[target][0]]['foo']['stdout']
- name: set_fact bar
set_fact:
bar: "{{ hostvars[groups[target][0]]['foo']['stdout'] }}"
- debug: var=bar
Final Output:
wmspt@dtl01lnxap01a:/staging_manh/manhattanansible$ ansible-playbook
pb-output-test.yml -e "target=Test5" -i 'inventories/staging/inventory'
