maas-region-controller 2.5.0~beta2-7291-gd0345ced5-0ubuntu1 (amd64 binary) in ubuntu cosmic

 The MAAS region controller (maas-regiond) is the REST API server for
 all MAAS clients, and the postgres database that maintains machine
 state for the entire data centre (or “region”). The region controller
 an be scaled-out and highly available given the appropriate postgres
 setup and additional API servers.
 .
 This package installs the postgres database and the API server, so it
 is appropriate for the initial installation of a new MAAS region. To
 scale out the controller or make it highly available, install
 maas-region-controller-api on additional servers and ensure the
 postgres database is HA too.
