#!/usr/bin/env sh

# Here is a script to deploy certificates to CloudHub V2 using Anypoint Platform REST APIs via curl
# A TLS Context is created and the certificates deployed on it
# (https://docs.mulesoft.com/cloudhub-2/ps-config-domains/)
#
# This script will use Connected Apps - Client Credentials
# The App must have "Cloudhub Network Administrator" or "Cloudhub Organization Admin" scope
# (https://docs.mulesoft.com/access-management/connected-apps-developers#developers)
#
# It requires following environment variables:
#
# CH2_CLIENT_ID - Connected App Client ID
# CH2_CLIENT_SECRET - Connected App Client Secret
# ORGANIZATION_ID - Anypoint Platform Organization ID
# CH2_PRIVATE_SPACE_ID - Private Space ID where the TLS Context will be created
#
#

#returns 0 means success, otherwise error.

#!/usr/bin/env sh

#Here is a sample custom api script.
#This file name is "myapi.sh"
#So, here must be a method   myapi_deploy()
#Which will be called by acme.sh to deploy the cert
#returns 0 means success, otherwise error.
