If the ``puppet`` key does not exist in global configuration, no action will be taken. If a config entry for ``puppet`` is present, then by default the latest version of puppet will be installed. If ``install`` is set to ``false``, puppet will not be installed. However, this will result in an error if puppet is not already present on the system. The version of puppet to be installed can be specified under ``version``, and defaults to ``none``, which selects the latest version in the repos. If the ``puppet`` config key exists in the config archive, this module will attempt to start puppet even if no installation was performed. The module also provides keys for configuring the new puppet 4 paths and installing the puppet package from the puppetlabs repositories: https://docs.puppet.com/puppet/4.2/reference/whered_it_go.html The keys are ``package_name``, ``conf_file``, ``ssl_dir`` and ``csr_attributes_path``. If unset, their values will default to ones that work with puppet 3.x and with distributions that ship modified puppet 4.x that uses the old paths. Puppet configuration can be specified under the ``conf`` key. The configuration is specified as a dictionary containing high-level ``<section>`` keys and lists of ``<key>=<value>`` pairs within each section. Each section name and ``<key>=<value>`` pair is written directly to ``puppet.conf``. As such, section names should be one of: ``main``, ``master``, ``agent`` or ``user`` and keys should be valid puppet configuration options. The ``certname`` key supports string substitutions for ``%i`` and ``%f``, corresponding to the instance id and fqdn of the machine respectively. If ``ca_cert`` is present, it will not be written to ``puppet.conf``, but instead will be used as the puppermaster certificate. It should be specified in pem format as a multi-line string (using the ``|`` yaml notation). Additionally it's possible to create a csr_attributes.yaml for CSR attributes and certificate extension requests.
