could not locate file in lookup to deploy authorized_keys

[Chang Eric]

I have a task like this

- name: test
  tags: key
  authorized_key:
    user: "{{ item }}"
    state: present
    key: "{{lookup('file', '/home/{{ item }}/.ssh/id_rsa.pub')}}"                                                                 
  with_items:
    - changch
  become_user: "{{ item }}"

 I'm sure the id_rsa.pub exists in local ansible controller (actually, the file exists on both node )

[minion@hqs009 ansiblecontrol]$ sudo ls -lart /home/changch/.ssh/id_rsa.pub
-rw------- 1 changch root 757 Mar 23  2018 /home/changch/.ssh/id_rsa.pub
[minion@hqs009 ansiblecontrol]$ 

but there are some error messages like this

 

task path: /home/mini/D/ansiblecontrol/roles/bootstrap-1804/tasks/main.yml:113
Tuesday 31 December 2019  09:01:40 +0800 (0:00:04.004)       0:00:04.141 ******

If you are sure the file exist on localhost then it's much likely a
permission issue.

With your sudo command you are checking with root user, root have all
permission, you need to check with the same user as the playbook.

sudo -u changch cat /home/changch/.ssh/id_rsa.pub
