How to use ansible 'expect' module for multiple different responses?
The reason is that the questions are interpreted as regexps. Hence you must escape characters with a special meaning in regular expressions, such as -()[]\?*. et cetara.
Hence:
'Enter current password for root (enter for none):'
should instead be:
'Enter current password for root \(enter for none\):'
Good luck!

Here I am trying to test my bash script where it is prompting four times.
#!/bin/bash date >/opt/prompt.txt read -p "enter one: " one echo $one echo $one >>/opt/prompt.txt read -p "enter two: " two echo $two echo $two >>/opt/prompt.txt read -p "enter three: " three echo $three echo $three >>/opt/prompt.txt read -p "enter password: " password echo $password echo $password >>/opt/prompt.txt
for this script I wrote the code below, and it is working fine
- hosts: "{{ hosts }}" tasks: - name: Test Script expect: command: sc.sh responses: enter one: 'one' enter two: 'two' enter three: 'three' enter password: 'pass' echo: yes
But if I am doing the same for
mysql_secure_installation
command it not working- hosts: "{{ hosts }}" tasks: - name: mysql_secure_installation Command Test expect: command: mysql_secure_installation responses: 'Enter current password for root (enter for none):': "\n" 'Set root password? [Y/n]:': 'y' 'New password:': '123456' 'Re-enter new password:': '123456' 'Remove anonymous users? [Y/n]:': 'y' 'Disallow root login remotely? [Y/n]:': 'y' 'Remove test database and access to it? [Y/n]:': 'y' 'Reload privilege tables now? [Y/n]:': 'y' echo: yes
and its trackback is here:
PLAY [S1] ********************************************************************** TASK [setup] ******************************************************************* ok: [S1] TASK [mysql_secure_installation Command Test] ********************************** fatal: [S1]: FAILED! => {"changed": true, "cmd": "mysql_secure_installation", "delta": "0:00:30.139266", "end": "2016-07-15 15:36:32.549415", "failed": true, "rc": 1, "start": "2016-07-15 15:36:02.410149", "stdout": "\r\n\r\n\r\n\r\nNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL\r\n SERVERS IN PRODUCTION USE!

I have also tried blank
''
instead of"\n"
for the first answer but it is not working either. I also visited Ansibleexpect
doc but they show only very simple example and explanation. I am also trying regex match for multiple different responses but it is also not working.
Please do not recommend me to use mysql module of Ansible, because here my purpose is to learn this module for future use.
