apt-transport-s3

Allow to have a privately hosted apt repository on S3. Access keys are read from /etc/apt/s3auth.conf file or IAM role if machine is hosted on AWS or has access to AWS metadata server on 169.254.169.254. They are also taken from the usual environment variables.

Requirements

Additional package dependencies (except installed by default in Debian)

1. python-configobj

Configuration

/etc/apt/s3auth.conf or IAM role can provide credentials required for using private apt repositories.

NOTE: Region MUST match the region the buckets are stored in and if not defined defaults to us-east-1.

Example of s3auth.conf file:

AccessKeyId = myaccesskey
SecretAccessKey = mysecretaccesskey
Region = 'us-east-1'

Usage

Install the .deb package from the releases page. The bucket repo should be specified using an s3:// prefix, for example:

deb s3://aptbucketname/repo/ trusty main contrib non-free

if you need to use a proxy to connect to the internet you can specify this as an APT configuration directive (for example in /etc/apt/apt.conf.d/90apt-transport-s3)

Acquire::http::Proxy "http://myproxy:3128/";

Testing

The module will run in interactive mode. It accepts on stdin and outputs on stdout. The messages it accepts on stdin are in the following format and documented here.

600 URI Acquire
URI:s3://my-s3-repository/project-a/dists/trusty/main/binary-amd64/Packages
Filename:Packages.downloaded
Fail-Ignore:true
Index-File:true

This message will trigger an s3 get from the above bucket and key and save it to Filename. It needs a blank line after the message to trigger the processing by the s3 method.
