I'd have to do some digging to look up the specifics. I handle this in my environment by generate the new host key on the puppetmaster and packaging that into an rpm, which gets installed in the kickstart along with puppet. That way an initial puppet run can happen during install. Doesn't exactly scale, unless you automate the key generation though, like you mentioned doing. -- ToddOpenPGP - KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ There are severe limits to the good that the government can do for the economy, but there are almost no limits to the harm it can do. -- Milton Friedman.

Re: [Puppet Users] First boot with Puppet
We done it 2 different ways: *) Pull and run a shellscript that sets puppet to run when the computer first boots up. Or instead of running the shell script, run something like this: get private_keys/bootstrap.pem (Pseudocode) get signed/bootstrap.pem (Pseudocode) get public_keys/ca.pem (Pseudocode) #Then run puppetd --no-daemonize --verbose --debug --hostprivkey=/var/lib/puppet/ssl/private_keys/bootstrap.pem --hostcert=/var/lib/puppet/ssl/certs/bootstrap.pem --onetime --certname=bootstrap /target/root/puppet.log #Now, when the computer reboots, the real run will happen with the computer's real name On Oct 14, 2010, at 3:47 AM, Michal Ludvig wrote: Hi guys, I'm installing Puppet on RHEL5 systems using KickStart but struggle with the first boot.

Why don't you use that feature? We're moving to cobbler, but we've been using our local sytem for last year with great success: We use a local script that generates our kickstart files. That script collects hostname and adds postinstall part, which looks like: [...] %post wget htpp://server./script.sh chmod +x script.sh script.sh hostname devide_type ip mask gw then, our script.sh runs puppet like: /usr/bin/ruby /usr/sbin/puppetd --server=server --logdest=/var/log/puppet/puppet.log --test --fqdn $1 *notice --fqdn and $1 is node hostname. So, with our conf, before first boot we have our host fully configured (puppet service is confgiured itself) The important thing is that we have autosign enabled for many hosts, so ca stuff is not needed (well, you have to previously puppetca --clean $hostname if you're reinstalling the node).

You can pass in arguments to the kernel via the bootloader which the
kickstart pre-script then read in.
Example.
while read key value; do
eval karg_${key}='${value:-1}'
done - EOF
$( /proc/cmdline sed 's/ /\n/g' | sed 's/=/\t/1')
EOF
Which are then used later in the script to set kickstart parameters or
wherever needed.
Then at the syslinux boot prompt, I do:
install-centos-5 ip=10.0.0.1/24 hostname=host.domain foo
which will install variables like so:
karg_ip=10.0.0.0/24
karg_hostname=host.domain
karg_foo=1
