Salt (or SaltStack) is a management system that can be used to keep applications and plugins synched across your render nodes. See the SaltStack Website for more information.
The Salt application plugin that ships with Deadline can be used to run a Salt update on a Worker as a Maintenance Job, thus allowing you to schedule a job which keeps your render nodes in software sync.
Note that Salt must already be configured to work outside of Deadline. Once your Salt system is set up, you can then submit a Salt job for Deadline to automatically trigger any applicable Salt updates.
You can submit Salt update jobs from the Monitor.
You can configure the Salt plug-in settings from the Monitor. While in super user mode, select Tools -> Configure Plugins and select the Salt plug-in from the list on the left.
