Hello all.
I know there were many discussions about how to remove hosts from puppet. I
know the script that removes all entries from the database.
What I am looking for is a solution that sets all exported resources to "ensure
=> absent". Assumed that they have a "ansure" parameter.
Anyway, I thought that the resources-type would be something that could help,
but I really don't get its use. I thought about something like:
node dead-host {
resources{"*":
ensure => "absent",
}
}
So, when dead-host runs puppet, all its resources will be set "absent".
This does not work and additionally it does not cover the case where dead-host
dies before having the chance to run for a last time (with the above snipplet)
To resolve the issue above, one would need the possibility to 'fake' the
dead-host from another puppet-host.
I have seen that puppetd has the "--fqdn" option, which seems to fake the
hostname.
Could I use this option on "alive-host" to do: "puppetd --fqdn
dead-host.domain.com -vt"? Would this result in "alive-host" being treated as
"dead-host"? If this would work, I could create a node definition with all
"anti"-classes and could deconfigure all hosts that no longer exist.
And the last question:
How do you all handle the case when hosts die. Do you simply remove all
storedconfigs and do not care about exported resources that might have been
imported by other hosts (ssh-keys, mounts, nagios-checks, ...)? Or do you go to
all those hosts and remove the resources by hand?
Thanks,
udo.
