Documentation

Dogestry

Simple CLI app for storing Docker image on Amazon S3.

Prerequisites

  • AWS account with at least one S3 bucket
  • Go 1.4 or higher (development only)
  • github.com/tools/godep (development only)
  • Docker 1.4 or higher

Installation

If you just want to run Dogestry, get the binary release that works for your platform. It's a statically linked binary: there are no dependencies. Uncompress it and run it!

If you prefer to build it yourself, clone the repo and godep go build

Usage

Setup

Typical S3 Usage:

$ export AWS_ACCESS_KEY=ABC
$ export AWS_SECRET_KEY=DEF
$ export DOCKER_HOST=tcp://localhost:2375
$ dogestry push s3://<bucket name>/<path name>/?region=us-east-1 <image name>
$ dogestry pull s3://<bucket name>/<path name>/?region=us-east-1 <image name>

Dogestry can run without a configuration file (example config dogestry.eg.cfg), but it's there if you need it.

By default dogestry looks for config file in ./dogestry.cfg.

Push

Push the hipache image to the S3 bucket ops-goodies located in us-west-2:

dogestry push s3://ops-goodies/ hipache

Push the hipache image to the S3 bucket ops-goodies located in us-west-2 with tag latest:

dogestry push s3://ops-goodies/ hipache:latest

Pull

Pull the hipache image and tag from S3 bucket ops-goodies:

dogestry pull s3://ops-goodies/ hipache

Pull the hipache image and tag from S3 bucket ops-goodies with tag latest:

dogestry pull s3://ops-goodies/ hipache:latest

If you want to pull an image from S3 to multiple hosts, you can use the -pullhosts option. The value for the -pullhosts option is a comma-separated list of hosts, in the following format: tcp://[host][:port] or unix://path.

The s3 version, with pullhosts:

dogestry -pullhosts tcp://host-1:2375,tcp://host-2:2375,tcp://host-3:2375 s3://ops-goodies/docker-repo/ hipache

S3 files layout

Dogestry will create two directories within your S3 bucket called "images" and "repositories". Example contents:
