+# This deploy hook will deploy ssl cert on kong proxy engine based on api request_host parameter.
+# Note that ssl plugin should be available on Kong instance
+# The hook will match cdomain to request_host, in case of multiple domain it will always take the first
+# one (acme.sh behaviour).
+# If ssl config already exist it will update only cert and key not touching other parameter
+# If ssl config doesn't exist it will only upload cert and key and not set other parameter
+# Not that we deploy full chain
+# See https://getkong.org/plugins/dynamic-ssl/ for other options
