Overview

Represents a directory that is created such that a catalog can be compiled in it. This has the following major functions:

  • Create the temporary directory that will serve as the puppet configuration directory

  • Register a handler to remove the temporary directory upon exit

  • Install needed configuration files within the directory (e.g. puppetdb.conf)

  • Install the facts into the directory

  • Install ‘environments/(environment)’ which is a symlink to the checkout of the puppet code

#install_ssl(logger, options) ⇒ Object

Install SSL certificate authority certificate, client key, and client certificate into the expected locations within Puppet’s SSL directory. Note that if the client key has a password, this will write the key (without password) onto disk, because Puppet doesn’t support unlocking the private key.

Parameters:

  • logger (Logger) —

    Logger object

  • options (Hash) —

    Options hash
