# Deprecated Class to serve Nova API and EC2 with apache mod_wsgi in place of nova-api and nova-api-ec2 services.
# Use ::nova::wsgi::apache::api.
#
# 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.
#

#
#   [*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 prefix for the endpoint.
#     Optional. Defaults to '/'
#
#   [*ssl*]
#     Use ssl ? (boolean)

#
#   [*workers*]
#     Number of WSGI workers to spawn.
#     Optional. Defaults to 1
#

#     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.

#
#   requires Class['apache'] & Class['nova'] & Class['nova::api']
#
# == Examples

# Note: we can't transform this class in a define for backward compatibility.
#       though this class might become a define in the future.
