I have a task with run\_once:true , which must run only on the first host and I need to use that hostname into a lookup file , something like this: - _name: Print facts_ _debug:_ _var: ansible\_nodename_ _register: admin\_host_ _- name: Set authorized key took from file_ _become: yes_ _authorized\_key:_ _user: root_ _state: present_ _key: “{{ lookup(‘file’, ‘/git/cephprep/files/{{ admin\_host }}/root/.ssh/id\_rsa.pub’) }}”_ Just this way it’s not working ---

Sorry, actually this is the result: [WARNING]: Unable to find ‘/git/cephprep/files/{‘ansible\_facts[“nodename”]’: ‘ha01’, ‘failed’: False, ‘changed’: False}/root/.ssh/id\_rsa.pub’ in expected paths (use -vvvvv to see paths) ---

Are all the tasks inside one playbook, or are different tasks in different jobs in an ansible tower workflow? Use set\_fact for within-playbook, and set\_stats for creating artifacts sent back to ansible tower to be presented as extra\_vars to downstream jobs in a workflow. For within-playbook: - set\_fact: admin\_host: “{{ ansible\_nodename }}” For downstream jobs in a workflow: - set\_stats: data: admin\_host: “{{ ansible\_nodename }}” If you need both you can do both. An artifact created with set\_stats in a playbook cannot be used later in that same playbook as a variable. You have to use set\_fact for that. For loading your file within the playbook or downstream - name: Set authorized key took from file become: yes authorized\_key: user: root state: present key: “{{ lookup(‘file’, ‘/git/cephprep/files/ **’ + admin\_host + '** /root/.ssh/id\_rsa.pub’) }}” NOTE that I broke up the file path and inserted the admin\_host with “+” which in Python (ansible runs on Python) will concatenate strings. ---
