ansible - Nothing happens when executing InstallHalyard.sh script via ansible-playbook - linux

Question

I'm trying to make a playbook to install halyard on a remote host using ansible-playbook. One of the tasks is to execute the "InstallHalyard.sh" wrapper scripts to the actual installer (reference: https://www.spinnaker.io/setup/install/halyard/).
No error / failure present, but also nothing has changed, as if the InstallHalyard.sh script is not executed. Though, it's fine if I do it by typing manual command. The other similar task works perfectly.
You can see the InstallHalyard.sh script implementation: here
Any idea about what is happening?
Here is the task in my playbook:
name: Run InstallHalyard.sh
become: yes
become_user: sudo
shell: "{{ ansible_env.HOME }}/.spinnaker/InstallHalyard.sh"
Any help would be appreciated, thank you very much :)
EDIT:
Already tried using script, command, and shell module.
FYI, the InstallHalyard.sh script will call itself by passing an env variable and needs to do curl -O
I'm suspecting the "export" operation inside the script doesn't work as Ansible has a different understandings for environment vars. (For example, ansible will not recognize "$HOME" instead it uses "{{ ansible_env.HOME }}".)
EDIT:
I found the script does an operation that makes a fork, does ansible handle this kind of operation?
Tested on localhost, got the same result.
SOLUTION
It is because of the different interpretation of environment vars of ansible. If I executed the script manually, the wrapper sets the environment variable and pass it to the next script calls, which ansible not able to do. So what I do is setting the environment var manually with ansible module before executing the script (just adding 2 lines)
Here is my revised task:
name: Run InstallHalyard.sh
become: yes
become_user: sudo
environment:
HAL_USER: "{{ ansible_env.USER }}"
shell: "{{ ansible_env.HOME }}/.spinnaker/InstallHalyard.sh"

Answer 1

The question is really how do I debug the output of a failing command. I'm guessing the command is failing with a useful error message but that message is not being displayed anywhere.
Here is an example to help debug this failing script:
-name: Run InstallHalyard.sh
become: yes
become_user: sudo
shell: "{{ ansible_env.HOME }}/.spinnaker/InstallHalyard.sh"
register: output
- debug: msg="{{ output.stdout }}"
- debug: msg="{{ output.stderr }}"
Try that is see what error message it was giving you.
