Overview

:startdoc::desc run packages

Runs packages on remote hosts by transfering a package directory using scp, and then executing one or more scripts via ssh. Run is configured using an ssh config file, which should contain all necessary ssh options.

Packages are transfered to hosts based on the basename of the package, hence ‘path/to/abox’ will run on the ‘abox’ host as configured in the ssh config file.
