copy files to remote servers but in a directory wh

I am working on an ansible playbook which copies my tasks.tar.gz file to remote servers and uncompress it into a particular directory on remote servers.

I am running my playbook on machineA as user david so I added public key of david user from machineA to all the remote servers authorized_key file so that I can ssh without typing my password because I want to run my ansible playbook passwordless.

---
- hosts: ALL
  serial: 3
  tasks:
      - name: copy and untar latest tasks.tar.gz file
        unarchive: src=tasks.tar.gz dest=/data/files/tasks/

      - name: sleep for few seconds
        pause: seconds=20

Now problem I am having is since this "/data/files/tasks/" directory on remote servers belongs to some other user (goldy) so it can't copy and uncompress tasks.tar.gz file because I am running my playbook as david user I guess.

ansible-playbook -e 'host_key_checking=False' test2.yml

I want to run my ansible playbook as user david passwordless but it should be able to copy files into all the remote servers in a directory which belongs to user goldy. I tried playing with become and become_user but it didn't worked for me. Is there anything else I need to do?

  - name: copy and untar latest tasks.tar.gz file
    unarchive: src=tasks.tar.gz dest=/data/files/tasks/
    become: true
    become_user: goldy
    become_method: sudo

This is the error I am getting:

"msg": "Failed to set permissions on the temporary files Ansible needs to create when becoming an unprivileged user (rc: 1, err: chown: changing ownership of ‘/tmp/ansible-tmp-1518323151.21-195554555527544/’: Operation not permitted\nchown: changing ownership of ‘/tmp/ansible-tmp-1518323151.21-195554555527544/stat.py’: Operation not permitted\n}).

Since you hint on having sudo configured for your connecting user david, the simplest thing you can do is use elevated permissions to copy the file and set its an ownership to goldy through owner parameter of the unarchive module:

- name: copy and untar latest tasks.tar.gz file
  unarchive:
    src: tasks.tar.gz
    dest: /data/files/tasks/
    owner: goldy
  become: true

For the question of how to configure sudoers to allow for executing commands on behalf of a user other than root, you need to learn how sudo and sudoers actually work (see the manual).
