acme.sh/deploy/localcopy.sh

#!/usr/bin/env sh

# Deploy-hook to very simply copy files to set directories and then
# execute whatever reloadcmd the admin needs afterwards. This can be
# useful for configurations where the "multideploy" hook (in development)
# is used or when an admin wants ACME.SH to renew certs but needs to
# manually configure deployment via an external script
# (e.g. The deploy-freenas script for TrueNAS Core/Scale
# https://github.com/danb35/deploy-freenas/ )
#
# If the same file is configured for the certificate key
# and the certificate and/or full chain, a combined PEM file will
# be output instead.
#
# Environment variables to be utilized are as follows:
#
# DEPLOY_LOCALCOPY_CERTKEY - /path/to/target/cert.key
# DEPLOY_LOCALCOPY_CERTIFICATE - /path/to/target/cert.cer
# DEPLOY_LOCALCOPY_FULLCHAIN - /path/to/target/fullchain.cer
# DEPLOY_LOCALCOPY_CA - /path/to/target/ca.cer
# DEPLOY_LOCALCOPY_PFX - /path/to/target/cert.pfx
# DEPLOY_LOCALCOPY_RELOADCMD - "echo 'this is my cmd'"
