Puppet Usage

This tool implements command line tools that can be used to query puppetdb.

Installation

Ensure that the lib directory is in Ruby's LOADPATH.

 $ export RUBYLIB=ruby-puppetdb/lib:$RUBYLIB

Usage

To get a list of the supported subcommands for the query face, run:

 $ puppet help query

You can run puppet help on the returned subcommands

$ puppet help query node
$ puppet help query fact
$ puppet help query resource

CLI

Each of the faces uses the following query syntax to return all objects found on a subset of nodes:

# get all nodes that contain the apache package and are in france, or all nodes in the us
$ puppet query node --query (Package[httpd] and country=fr) or country=us)'

Each of the individual faces returns a different data format:

node - a list of nodes identified by a name

 $ puppet query node --query '(Package[mysql-server] and architecture=amd64)'
   ["db_node_1", "db_node2"]

fact - a hash of facts per node

 $ puppet query fact --query '(Package[mysql-server] and architecture=amd64)'
   db_node_1  {"facterversion":"1.6.9","hostname":"controller",...........}
   db_node_2  {"facterversion":"1.6.9","hostname":"controller",...........}

resource - a hash of resources that contains node membership of each resource

$ puppet query resource --query '(Package[mysql-server] and architecture=amd64)'

Each of the individual faces also accepts --filter which can be used to modified the returned results.

node - by default, it returns the node names of nodes that match the query. The --filter command accepts a single fact name that can be used to return to represent each node (instead of node name)

$ puppet query node --query '(Package[mysql-server] and architecture=amd64)' --filter fqdn
  ["db_node_1.mydomain.com", "db_node2.my_domain.com"]

fact - by default, it returns all facts for all nodes that match the query. The --filter option accepts a ',' delimited list of fact names to return.

$ puppet query fact --query '(Package[mysql-server] and architecture=amd64)' --filter uptime,architecture
  db_node_1  {"architecture":"amd64","uptime":"0:01 hours"}
  db_node_2  {"architecture":"amd64","uptime":"0:26 hours"}

resource - by default, it returns all resources together with their membership for all nodes. The --filter accepts a ',' delimited list of resource references that can be used to specify the exact resources to return.

$ puppet query resource --query '(Package[mysql-server] and architecture=amd64)' --filter Package[mysql-server] --render-as yaml
14fc9c1fbfa37e93afe9799fd927948b41280764:
  parameters:
    ensure: present
  type: Package
  nodes:
    - db_node_1
    - db_node_2
  title: mysql-server

Each of the types also support the --only-active option.

Ruby

faces can be called from the ruby in exactly they same way they are called from the command line:

$ irb> require 'puppet/face'
  irb> Puppet::Face[:query, :current].node(:query => '(Package[mysql-server] and architecture=amd64)', :filter => 'fqdn')
