# 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 |
