Configuration: Editing settings on the command line

This version of Puppet is not included in Puppet Enterprise. The latest version of PE includes Puppet 4.8.

Puppet loads most of its settings from the puppet.conf config file. You can edit this file directly, or you can change individual settings with the puppet config set command.

When to Use This

We recommend using puppet config set for:

  • Fast one-off config changes
  • Scriptable config changes in provisioning tools

If you find yourself changing many settings at once, you might prefer to edit the puppet.conf file or manage it with a template.

Usage

To assign a new value to a setting, run:

$ sudo puppet config set <SETTING NAME> <VALUE> --section <CONFIG SECTION>

This will declaratively set the value of <SETTING NAME> to <VALUE> (in the specified config section). It will work the same way regardless of whether the setting already had a value.

Config sections

The --section option specifies which section of puppet.conf to modify. It is optional, and defaults to main. Valid sections are:

  • main (default) — used by all commands and services
  • master — used by the Puppet master service and the puppet cert command
  • agent — used by the Puppet agent service
  • user — used by the Puppet apply command and most other commands

If modifying the system config file, be sure to use sudo or run the command as root or Administrator.

Example

Before:

# /etc/puppetlabs/puppet/puppet.conf
[main]
certname = agent01.example.com
server = master.example.com
vardir = /var/opt/lib/pe-puppet

[agent]
report = true
graph = true
pluginsync = true

[master]
dns_alt_names = master,master.example.com,puppet,puppet.example.com

Commands:

$ sudo puppet config set reports puppetdb --section master
$ sudo puppet config set ordering manifest

After:

# /etc/puppetlabs/puppet/puppet.conf
[main]
certname = agent01.example.com
server = master.example.com
vardir = /var/opt/lib/pe-puppet
ordering = manifest

[agent]
report = true
graph = true
pluginsync = true

[master]
dns_alt_names = master,master.example.com,puppet,puppet.example.com
reports = puppetdb
