Check the minion's
/var/log/salt/minion
to get the full python stacktrace.
Salt Modules won't Execute
Here there be dragons.
If you're lucky, the salt modules documentation will stipulate a requirement. For example, see the note on salt.modules.gpg.
In most cases, a problem can be pinned down by reading stacktraces in/var/log/salt/minion
.Here are some modules that I bang my head against frequently.
gpg
- install gpg
- install python-gpg to saltstack's python interpreter
pip
Most of my problems here come from:
- salt using the global python installation rather than a virtualenv
- my package manager installing a newer package than salt supports.
Unfortunately this is a moving target, and pinning packages becomes a bit of a headache.
(I did try salt in a virtualenv, but gave after hours debugging issues with salt's protocol decoding)Verify using logs:
/var/log/salt/minion
