Homestead provides a web services interface to Sprout for retrieving authentication credentials and user profile information. It can either master the data (in which case it exposes a web services provisioning interface) or can pull the data from an IMS compliant HSS over the Cx interface. The Homestead nodes run as a cluster using Cassandra as the store for mastered/cached data.
Note: This is my attempt to build the container - but I recommend using docker-compose to orchestrate and put everything together. Check out - https://github.com/Metaswitch/clearwater-docker
