NAME

SYNOPSIS

Trigger a puppetd run on a set of hosts.

USAGE

puppetrun [-a|--all] [-c|--class <class>] [-d|--debug] [-f|--foreground]

[-h|--help] [--host <host>] [--no-fqdn] [--ignoreschedules] [-t|--tag <tag>] [--test] [-p|--ping]

DESCRIPTION

This script can be used to connect to a set of machines running +puppetd+ and trigger them to run their configurations. The most common usage would be to specify a class of hosts and a set of tags, and +puppetrun+ would look up in LDAP all of the hosts matching that class, then connect to each host and trigger a run of all of the objects with the specified tags.

If you are not storing your host configurations in LDAP, you can specify hosts manually.

You will most likely have to run +puppetrun+ as root to get access to the SSL certificates.

+puppetrun+ reads +puppetmaster+aqs configuration file, so that it can copy things like LDAP settings.

USAGE NOTES

+puppetrun+ is useless unless +puppetd+ is listening. See its documentation for more information, but the gist is that you must enable +listen+ on the +puppetd+ daemon, either using +--listen+ on the command line or adding aqlisten: trueaq in its config file. In addition, you need to set the daemons up to specifically allow connections by creating the +namespaceauth+ file, normally at aq/etc/puppet/namespaceauth.confaq. This file specifies who has access to each namespace; if you create the file you must add every namespace you want any Puppet daemon to allow -- it is currently global to all Puppet daemons.

An example file looks like this:

 [fileserver]
     allow *.madstop.com
 
 [puppetmaster]
     allow *.madstop.com
 
 [puppetrunner]
     allow culain.madstop.com
 

This is what you would install on your Puppet master; non-master hosts could leave off the aqfileserveraq and aqpuppetmasteraq namespaces.

Expect more documentation on this eventually.

OPTIONS

Note that any configuration parameter thataqs valid in the configuration file is also a valid long argument. For example, aqssldiraq is a valid configuration parameter, so you can specify aq--ssldir <directory>aq as an argument.

See the configuration file documentation at http://puppetlabs.com/projects/puppet/reference/configref.html for the full list of acceptable parameters. A commented list of all configuration options can also be generated by running puppetmasterdd with aq--genconfigaq.

all: Connect to all available hosts. Requires LDAP support

at this point.

class: Specify a class of machines to which to connect. This

only works if you have LDAP configured, at the moment.

debug: Enable full debugging.

foreground: Run each configuration in the foreground; that is, when

connecting to a host, do not return until the host has finished its run. The default is false.

help: Print this help message

host: A specific host to which to connect. This flag can be

specified more than once.

ignoreschedules: Whether the client should ignore schedules when running

its configuration. This can be used to force the client to perform work it would not normally perform so soon. The default is false.

parallel: How parallel to make the connections. Parallelization

is provided by forking for each client to which to connect. The default is 1, meaning serial execution.

tag: Specify a tag for selecting the objects to apply. Does

not work with the --test option.

test: Print the hosts you would connect to but do not

actually connect. This option requires LDAP support at this point.

ping:

 Do a ICMP echo against the target host. Skip hosts that donaqt respond to ping.
 

EXAMPLE

sudo puppetrun -p 10 --host host1 --host host2 -t remotefile -t webserver
