Cloudbreak uses Saltstack to install Ambari and the necessary packages for the HDP/HDF provisioning. Salt Master always runs alongside the Ambari Server node. Each instance in the cluster runs a Salt Minion, which connects to the Salt Master.
There can be multiple Salt Masters if the cluster is configured to run in HA (High Availability) mode and in this case each Salt Minion connects to each Salt Master.
Cloudbreak also uses SaltStack to execute user-provided customization scripts called “recipes”.
Salt Master and Salt Minion logs can be found at the following
