Update haproxy deploy hook
Add functionality to add OCSP stapling info (.ocsp file), issuer (.issuer file) and multi-cert bundles (suffix on pem file based on key type). This also corrects the order of key, certificate and intermediate in the PEM file, which although HAProxy does not seem to care, was incorrect in the prior version.

#returns 0 means success, otherwise error.

# 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.
