In my experience we've handled this in a few ways:
- Postgres has ident auth, which avoids the use of password for local
accounts, which helps in a lot of cases.
- Puppet has the concept of an "external node classifier". This is a
script which gets called with the name of the node, and can return
data which is then available to the puppet run. So the password is
stored elsewhere (in our case Foreman) which means you only need to
worry about the people who can access the Foreman server or the
puppet server. Note people who can check arbitrary things into the
repo and view the puppet output would be able to get the password by
printing it to the debug log.
- Punt. Check in the password but set the access controls so it only
work for very few IPs, then you only need to worry about people who
can log into *those* machines. Which is controlled by public SSH
keys which you can check-in safely. Not super safe, but for
read-only accounts for e.g. nagios might be ok.
Hope this helps,
