#!/usr/bin/env sh
# Script for acme.sh to deploy certificates to haproxy
#
# The following variables can be exported:
#
# export DEPLOY_HAPROXY_PEM_NAME="${domain}.pem"
#
# Defines the name of the PEM file.
# Defaults to "<domain>.pem"
#
# export DEPLOY_HAPROXY_PEM_PATH="/etc/haproxy"
#
# Defines location of PEM file for HAProxy.
# Defaults to /etc/haproxy
#
# export DEPLOY_HAPROXY_RELOAD="systemctl reload haproxy"
#
# OPTIONAL: Reload command used post deploy
# This defaults to be a no-op (ie "true").
# It is strongly recommended to set this something that makes sense
# for your distro.
#
# export DEPLOY_HAPROXY_ISSUER="no"
#
# OPTIONAL: Places CA file as "${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.
#
# export DEPLOY_HAPROXY_HOT_UPDATE="yes"
# export DEPLOY_HAPROXY_STATS_SOCKET="UNIX:/run/haproxy/admin.sock"
#
# OPTIONAL: Deploy the certificate over the HAProxy stats socket without
# needing to reload HAProxy. Default is "no".
#
# Require the socat binary. DEPLOY_HAPROXY_STATS_SOCKET variable uses the socat
# address format.
#
# export DEPLOY_HAPROXY_MASTER_CLI="UNIX:/run/haproxy-master.sock"
#
# OPTIONAL: To use the master CLI with DEPLOY_HAPROXY_HOT_UPDATE="yes" instead
# of a stats socket, use this variable.
