#!/usr/bin/env sh
# Script for acme.sh to deploy certificates to haproxy
#
# The following variables can be exported:
#
# export DEPLOY_HAPROXY_PEM=""
#
# REQUIRED: Defines location of PEM file for HAProxy
#
# export DEPLOY_HAPROXY_RELOAD="systemctl reload haproxy"
#
# OPTIONAL: Reload command used post deploy
#
# export DEPLOY_HAPROXY_ISSUER="no"
#
# OPTIONAL: Places CA file as "${DEPLOY_HAPROXY_PEM}.issuer"
# Note: Required for OCSP stapling to work
#
# export DEPLOY_HAPROXY_BUNDLE="no"
#
# OPTIONAL: Deploy this certificate as part of a multi-cert bundle
# This adds a suffix to the certificate based on the certificate type
# eg RSA certificates will have .rsa as a suffix to the file name
# HAProxy will load all certificates and provide one or the other
# depending on client capabilities
# Note: This functionality requires HAProxy was compiled against
# a version of OpenSSL that supports this.
