I am setting up a playbook that automatically configures my workstation. This will hopefully allow me to quickly install linux somewhere and automatically have all the resources I need.

One of the steps is installing homebrew and I cannot figure out how to do it.

I have created this playbook

- hosts: localhost
  become: yes
  become_user: myUser
  tasks:
  - name: Download homebrew install script from source
    get_url:
      url: https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh
      dest: ~/Downloads/install_homebrew.sh
      mode: 'u+rwx'
  - name: Install homebrew
    shell: ~/Downloads/install_homebrew.sh 

and run it with ansible-playbook myplaybook.yaml.

However, when I execute it, there is a permission denied error. Apparently this is because of how the copy-module works (here). So I thought I'd just run the sudo ansible-playbook myplaybook.yaml instead. This leads to the exact same permission error. I guess this is because I have become_user: myUser.

However, when i remove become_user, I obviously get another error Destination /root/Downloads does not exist because my destination is coded to the users download-directory.

So how can I execute the playbook as the user myUser but with root privileges? This would allow me to access the root-stuff but still refer to my home-directory. In theory this should be possible since I can run

sudo ls -a /root && ls ~/

and get both the content of the root-folder and of my home directory. But I don't know how to do this in ansible.
