# Class to serve Nova API and EC2 with apache mod_wsgi in place of nova-api and nova-api-ec2 services.
#
# Serving Nova API and Nova API EC2 from apache is the recommended way to go for production
# because of limited performance for concurrent accesses.
#
# When using this class you should disable your nova-api and nova-api-ec2 service.
#
# == Parameters
#
# [*servername*]
# The servername for the virtualhost.
# Optional. Defaults to $::fqdn
#
# [*api_port*]
# The port for Nova API service.
# Optional. Defaults to 8774
#
# [*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 $::os_workers
#
# [*priority*]
# (optional) The priority for the vhost.
# Defaults to '10'
#
# [*threads*]
# (optional) The number of threads for the vhost.
# Defaults to 1
#
# [*wsgi_process_display_name*]
# (optional) Name of the WSGI process display-name.
# Defaults to undef
#
# [*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.
#
# [*access_log_file*]
# The log file name for the virtualhost.
# Optional. Defaults to false.
#
# [*access_log_format*]
# The log format for the virtualhost.
# Optional. Defaults to false.
#
# [*error_log_file*]
# The error log file name for the virtualhost.
# Optional. Defaults to undef.
#
# [*custom_wsgi_process_options*]
# (optional) gives you the oportunity to add custom process options or to
# overwrite the default options for the WSGI main process.
# eg. to use a virtual python environment for the WSGI process
# you could set it to:
# { python-path => '/my/python/virtualenv' }
# Defaults to {}
#
# == Dependencies
#
# requires Class['apache'] & Class['nova'] & Class['nova::api']
#
# == Examples
#
# include apache
#
# class { 'nova::wsgi::apache': }
#
