#
#      include midonet::repository
#
# And puppet will configure the system to use the latest stable version
# of MidoNet OSS.
#
# To install other releases than the last default's Midonet OSS, you can
# override the default's midonet_repository atributes by a resource-like
# declaration:
#
#     class { 'midonet::repository':
#         midonet_repo            => 'http://repo.midonet.org/midonet/v2014.11',
#         midonet_openstack_repo  => 'http://repo.midonet.org/openstack',
#         midonet_thirdparty_repo => 'http://repo.midonet.org/misc',
#         midonet_key             => '50F18FCF',
#         midonet_stage           => 'stable',
#         midonet_key_url         => 'http://repo.midonet.org/packages.midokura.key',
#         manage_distro_repo      => true,
#         manage_epel_repo        => true,
#         openstack_release       => 'juno'
#     }
#
# or use a YAML file using the same attributes, accessible from Hiera:
#
#     midonet::repository::midonet_repo: 'http://repo.midonet.org/midonet/v2014.11'
#     midonet::repository::midonet_openstack_repo: 'http://repo.midonet.org/openstack'
#     midonet::repository::midonet_thirdparty_repo: 'http://repo.midonet.org/misc'
#     midonet::repository::midonet_key: '50F18FCF'
#     midonet::repository::midonet_stage: 'stable'
#     midonet::repository::midonet_key_url: 'http://repo.midonet.org/packages.midokura.key'
