Salt version 0.12.0 introduced the ability for the Salt Master to integrate different file server backends. File server backends allows the Salt file server to act as a transparent bridge to external resources. The primary example of this is the git backend which allows for all of the Salt formulas and files to be maintained in a remote git repository.
The fileserver backend system can accept multiple backends as well. This makes
it possible to have the environments listed in the file_roots
configuration available in addition to other backends, or the ability to mix
multiple backends.
This feature is managed by the fileserver_backend option in the
master config. The desired backend systems are listed in order of search
priority:
fileserver_backend:
- roots
- git
With this configuration, the environments and files defined in the
file_roots parameter will be searched first, if the referenced
environment and file is not found then the git
backend will be searched.
The concept of environments is followed in all backend systems. The
environments in the classic roots backend are
defined in the file_roots option. Environments map differently
based on the backend, for instance the git backend translated branches and tags
in git to environments. This makes it easy to define environments in git by
just setting a tag or forking a branch.
