IT-Common-Platform-Landlord#

This project consists of a folder per cluster and configuration files in each of those for the tenant of those clients. It was originally written to be extensible, but all current customers keep all the client config information in a tenant-config-0.yaml. This file holds all the values that allows Landlord to spin up the various tenants. In addition, to help keep the code clean, there is a syntax checker along with linting.
