# 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"
|

#

# 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="/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.
