Update haproxy deploy hook (#1591)
* implement basic haproxy deploy HAProxy requires the certificate chain and key to be concatenated and placed somewhere (can be anywhere). This script expects a single environment variable with the path where the concatenated PEM file should be written * add docs for HAProxy deployment * Add conditional check to ensure path is provided * remove whitespace * remove more whitespace (trying to get TravisCI working) * add reload * update for POSIX compliance * add documentation for reload command * 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. * Document updated haproxy deploy hook * Fix variable name * whitespace fixes * Support HAPROXY_DEPLOY_PEM_PATH Adds compatibility to original haproxy deploy hook while still allowing custom PEM file name (via HAPROXY_DEPLOY_PEM_NAME) * update for new haproxy deploy vars * Fix return from reload * Fix Le_Keylength case * Update cert suffix for bundles .ocsp generation * Whitepspace * Change default for reload * Readme update * Actually set reload default * Fix README.md confict

#Here is a script to deploy cert to haproxy server.
|

|
||||
#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_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.
