How to pass multiple executable in ansible within a shell module? - ansible

Question

I am trying to pass a prompt y in ansible when it executes command.
When i do manually on server it asks for a prompt.
The issue is for command to run i need to pass the executable /bin/bash
command: source /etc/profile.d/tableau_server.sh && tsm pending-changes apply for expect command to run i need to pass /usr/bin/expect .
My question, how can i pass 2 executable in ansible such that for command it uses /bin/bash and for expect prompt it should use /usr/bin/expect and the error is because i am using source, what is an alternative i can use?
Update: I dont know why but i am not able to pass --ignore-prompt , It gives an error
ubuntu#ip-xx-xxx-xx-xx:~$ tsm pending-changes apply --ignore-prompt
Unrecognized option: --ignore-prompt
Please help me with a solution!
ubuntu#ip-xx-xxx-xx-xx:~$ tsm pending-changes apply
This operation will perform a server restart. Are you sure you wish to continue?

My ansible script:
shell: |
source /etc/profile.d/tableau_server.sh && tsm pending-changes apply
expect "This operation will perform a server restart. Are you sure you wish to continue?\n(y/n):"
send "y\n"
exit 0
args:
executable: /usr/bin/expect
args:
executable: /bin/bash/expect

Answer 1

I would say you are doing far too much with bash commands and '&&' inside command, none of this feels idempotent.
Can I recommend going back to the drawing board with this. I would recommend creating the command using the 'creates' parameter so it can tell if it needs to run.
https://docs.ansible.com/ansible/2.6/modules/command_module.html
Or alternatively check before hand which will then see if the command needs running using register.
In this instance of your issue with the:
tsm pending-changes apply
should support as per https://onlinehelp.tableau.com/current/server-linux/en-us/cli_pending-changes.htm
tsm pending-changes apply --ignore-prompt
which will then not prompt for a yes and will not need the expect module.

I solved my issue by passing an -r option.
- name: Initialize and Start Tableau Server
shell: source /etc/profile.d/tableau_server.sh && tsm pending-changes apply -r -u ubuntu -p '{{ tableau_server_admin_password }}'
args:
executable: /bin/bash
when: inventory_hostname == "xx.xxx.xx.xx"
