custom_config.pp

# @summary
# Adds a custom configuration file to the Apache server's `conf.d` directory.
#
# If the file is invalid and this defined type's `verify_config` parameter's value is
# `true`, Puppet throws an error during a Puppet run.
#
# @param ensure
# Specifies whether the configuration file should be present.
#
# @param confdir
# Sets the directory in which Puppet places configuration files.
#
# @param content
# Sets the configuration file's content. The `content` and `source` parameters are exclusive
# of each other.
#
# @param filename
# Sets the name of the file under `confdir` in which Puppet stores the configuration.
#
# @param priority
# Sets the configuration file's priority by prefixing its filename with this parameter's
# numeric value, as Apache processes configuration files in alphanumeric order.<br />
# To omit the priority prefix in the configuration file's name, set this parameter to `false`.
#
# @param source
# Points to the configuration file's source. The `content` and `source` parameters are
# exclusive of each other.
#
# @param verify_command
# Specifies the command Puppet uses to verify the configuration file. Use a fully qualified
# command.<br />
# This parameter is used only if the `verify_config` parameter's value is `true`. If the
# `verify_command` fails, the Puppet run deletes the configuration file and raises an error,
# but does not notify the Apache service.
#
# @param verify_config
# Specifies whether to validate the configuration file before notifying the Apache service.
#
# @param owner
# File owner of configuration file
#
# @param group
# File group of configuration file
#
# @param file_mode
# File mode of configuration file
#
# @param show_diff
# show_diff property for configuration file resource
#
