#
# Class to serve Cinder API with apache mod_wsgi in place of cinder-api service.
#
# Serving Cinder API from apache is the recommended way to go for production
# because of limited performance for concurrent accesses when running eventlet.
#
# When using this class you should disable your cinder-api service.
#
# == Parameters
#
# [*servername*]
# The servername for the virtualhost.
# Optional. Defaults to $::fqdn
#
# [*port*]
# The port.
# Optional. Defaults to 8776
#
# [*bind_host*]
# The host/ip address Apache will listen on.
# Optional. Defaults to undef (listen on all ip addresses).
#
# [*path*]
# The prefix for the endpoint.
# Optional. Defaults to '/'
#
# [*ssl*]
# Use ssl ? (boolean)
# Optional. Defaults to true
#
# [*workers*]
# Number of WSGI workers to spawn.
# Optional. Defaults to 1
#
# [*priority*]
# (optional) The priority for the vhost.
# Defaults to '10'
#
# [*threads*]
# (optional) The number of threads for the vhost.
# Defaults to $::processorcount
#
# [*ssl_cert*]
# [*ssl_key*]
# [*ssl_chain*]
# [*ssl_ca*]
# [*ssl_crl_path*]
# [*ssl_crl*]
# [*ssl_certs_dir*]
# apache::vhost ssl parameters.
# Optional. Default to apache::vhost 'ssl_*' defaults.
#
# == Dependencies
#
# requires Class['apache'] & Class['cinder']
#
# == Examples
#
# include apache
#
# class { 'cinder::wsgi::apache': }
