Hi,

I am using ansible-playbook at a script and passing password to t. Below is how i used it:

run.sh

#!/bin/bash

…

/bin/expect \<\<- DONE  
spawn ansible-playbook -i $1 $2 -u $Username -k --become-user root --become-method sudo --become  
expect "SSH password: "  
send “$Password\r”  
expect eof  
DONE

$ bash run.sh test.txt test/playbook.yml

# cat cyberark.txt

[all]  
FOO01  
FOO02  
FOO03  
FOO04  
FOO05

# bash run.sh foo.txt test/playbook.yml

spawn ansible-playbook -i test.txt foo/playbook.yml -u testuser -k --become-user root --become-method sudo --become  
SSH password:

Any idea why the playbook is ended at the 3rd one? when i use a inventory with two hosts, everything is fine. When the number of hosts in inventory increases, ansible is ending at some hosts.

It may be because of spawn usage. Any solution will be appreciated.

Ansible has tty detection which controls it's prompt behaviour, that  
might be affecting your playbook.

So what do you suggest?

Any other method to enter password at a bash script?

You can set the ansible\_ssh\_pass variable, preferably in inventory.

</div>

The password is being gathered by a curl command so it is dynamic. Is there a way to set ssh\_pass variable dynamic? Like something to get from an environment variable?

Great tip.

Here is my folder structure:

group\_vars/all

some\_playbook/playbook.yml

inventory\_file

$ ansible-playbook -i inventory\_file some\_playbook/playbook.yml --become-user root --become-method sudo --become

# cat group\_vars/all

The lookup method sounds more Ansible way. timeout -1 solved the issue by the way. But i would like to solve the lookup problem also.

There is a default time out value for expect. That’s why its timing out. To disable the timeout, we are setting as -1. I don’t think its ansible issue.

</div>

Instead of using expect, setting the ansible\_ssh\_pass is another solution. Instead of running ansible-playbook inside a script, i can directly use it and it may get the ssh password from group\_vars variable. I couldn’t make it, thats what i am trying to do now.

If you are logging in as root you don't need become to root.

If the password is correct this should work.  
So is the passwword correct?  
Make sure your script add a new line at the end.
