Puppet in a bash script

[Harish Agarwal]

Hello,

I'm using puppet via a bash script when I spin up a machine to configure it.  I'd like to restart the instance after puppet's run is complete.  In my bash script I have:

puppet agent --test

shutdown -r now

Puppet runs to completion, but "shutdown -r now" never executes.  I'm not sure why not - these are the last two lines in my bash script and everything else executes successfully.  Any help would be greatly appreciated.

I'm not sure where you execute this, but this sound like a problem
with your path.
For initialization script and such, where you're unsure of the path, I
suggest using the complete path for the command.
For example /usr/bin/puppet and /sbin/shutdown.

Can you get the exit code of the puppet run and then, based on success or failure, do the reboot?

puppet agent --test
ANSW=$?
if [[ ${ANSW} -eq 0 ]]
then
echo "Puppet successful - Exit code ${ANSW}"
/sbin/shutdown -r now
else
echo "No puppet run - Exit code ${ANSW}
fi

This may tell you if puppet is cancelling the shutdown...

I did the echo above and didn't get any output....  It's as if this command is never encountered.  If there are errors thrown during the puppet run, will it throw an error and prevent the next command from executing?

BTW, I do have the full path of the binaries in my shell script now.

Try adding -x to the bash (first line) to output each command as they are run...

What if you removed everything in the script but the shutdown
command.. does it work?

If the shell is configured that way: Yes. Try to write the output of »set -o«
somewhere and look if »errexit« is set. If that is the case bash will
leave the script as soon as a command returns a non-true value.

Caution: puppet agent --test will return non-zero exit code if any
resources needed changing.

If in doubt, prefer puppet agent --one-time --no-daemonize (typos
notwithstanding).

Otherwise, I'm stumped, this shouldn't happen. You could try and execute
puppet in a subshell and see if the rest of the script is run then.

( puppet agent --test )
