To clarify my question, when Ansible calls a dynamic inventory script that
reads in a password, for example:
#!/bin/sh
read -s cmdb_password
echo $cmdb_password > /tmp/test.out
cat /tmp/test.json
I find that when I run Ansible, it is waiting for input. I give it a line
of input and then it is still waiting for input! Then I give it a second
line of input, and then it keeps going. The second line is what gets
logged to /tmp/test.out.
What's going on? Where does the first line go?
Here is how I test:
( echo one; echo two) | ansible -i ./test.sh all --list-hosts
I find the string "two" in my log file /tmp/test.out
Best,
