salt.fileserver.s3fs¶

Amazon S3 Fileserver Backend

This backend exposes directories in S3 buckets as Salt environments. To enable this backend, add s3fs to the fileserver_backend option in the Master config file.

fileserver_backend:
  - s3fs

S3 credentials must also be set in the master config file:

s3.keyid: GKTADJGHEIQSXMKKRBJ08H
s3.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

Alternatively, if on EC2 these credentials can be automatically loaded from instance metadata.

This fileserver supports two modes of operation for the buckets:

1. A single bucket per environment

   s3.buckets:
     production:
       - bucket1
       - bucket2
     staging:
       - bucket3
       - bucket4
   

2. Multiple environments per bucket

   s3.buckets:
     - bucket1
     - bucket2
     - bucket3
     - bucket4
   

Note that bucket names must be all lowercase both in the AWS console and in Salt, otherwise you may encounter SignatureDoesNotMatch errors.

A multiple-environment bucket must adhere to the following root directory structure:

s3://<bucket name>/<environment>/<files>
