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>

注解

This fileserver back-end requires the use of the MD5 hashing algorithm. MD5 may not be compliant with all security policies.
