I am running into the limitations of ansible fetch module. Trying to get a somewhat big file – between 1MB and 250MB – which is chearly too much for fetch.

- name: get result files back
  fetch:
    src: /tmp/file_generated_previous_step.tar.gz
    dest: file_generated_{{ inventory_hostname }}.tar.gz
    flat: yes

This works when my result file is small, but gives a looooong error when the file is about 1-2MB.

My workaround is to scp the file from the controlling host, like this:

- name: get result files back
  shell: ' scp {{ inventory_hostname }}:/tmp/file_generated_previous_step.tar.gz file_generated_{{ inventory_hostname }}.tar.gz'
  delegate_to: localhost

This is working ok, when I have pubkey auth with no password to the host. But has no error handling, whatsoever.

So my question is: is there a correct method to achieve the same result? Constraint: Ansible 2.4

Best regards,
Trifo
