Ansible Tip: Running Interactive Scripts with Ansible

Some­times when you run a script with Ansi­ble it requires an inter­ac­tive prompt like y/n or some­thing similar.

I recently ran into this prob­lem and after a bit of head bash­ing I found the fol­low­ing solu­tion in a lit­tle Linux util­ity called ‘yes’ which repeat­edly out­puts a line with a spec­i­fied STRING(s), or ‘y’. In this case I just needed ‘y’ so I went with the default.

Here is my Ansi­ble Task file with the ‘yes’ com­mand in use:

# file: roles/apigee_edge_base/tasks/apigee_install.yml

# slight hack below we pipe the "yes" command to send a y to our installer script because it complains about the OS version not being supported!
- name: Apigee Install - Run the shell script to setup the environment
 shell: yes | ./ -r /opt -d /opt -j /usr/java/default
 chdir: "{{ unpack_dir }}/apigee-edge-{{ edge_version }}"
 remote_user: root
 sudo: yes

If you know a more ele­gant way to do this then let me know (I thought about ‘echo y |’ as well but liked this one).
