# == Resource: tripleo::certmonger::haproxy
#
# Request a certificate for the HAProxy service and does the necessary logic to
# get it into a format that the service understands.
#
# === Parameters
#
# [*service_pem*]
# The file in PEM format that the HAProxy service will use as a certificate.
#
# [*service_certificate*]
# The certificate file that certmonger will be tracking.
#
# [*service_key*]
# The key file that certmonger will use for the certificate.
#
# [*hostname*]
# The hostname that certmonger will use as the common name for the
# certificate.
#
# [*certmonger_ca*]
# (Optional) The CA that certmonger will use to generate the certificates.
# Defaults to hiera('certmonger_ca', 'local').
#
# [*dnsnames*]
# (Optional) The DNS names that will be added for the SubjectAltNames entry
# in the certificate. If left unset, the value will be set to the $hostname.
# Defaults to undef
#
# [*principal*]
# The haproxy service principal that is set for HAProxy in kerberos.
#
# [*postsave_cmd*]
# The post-save-command that certmonger will use once it renews the
# certificate.
