# Script to create certificate to Alibaba Cloud CDN
#
# Docs: https://github.com/acmesh-official/acme.sh/wiki/deployhooks#33-deploy-your-certificate-to-alibaba-cloud-cdn-aliyun
#
# This deployment required following variables
# export Ali_Key="ALIACCESSKEY"
# export Ali_Secret="ALISECRETKEY"
# The credentials are shared with all the Alibaba Cloud deploy hooks and dnsapi
#
# To specify the CDN domain that is different from the certificate CN, usually used for multi-domain or wildcard certificates
# export DEPLOY_ALI_CDN_DOMAIN="cdn.example.com"
# If you have multiple CDN domains using the same certificate, just
# export DEPLOY_ALI_CDN_DOMAIN="cdn1.example.com cdn2.example.com"

# Load dnsapi/dns_ali.sh to reduce the duplicated codes
