Snakes on a plane

Snakes-on-a-plane is a set of docker containers for running docker when you have no or restricted internet connectivity -- like when you are on an airplane. A container for a local docker registry exists, but other pieces of infrastructure are necessary to run with limited connectivity.

Development on this began during the Docker Hackathon 2014-10-30.

Scope

The project is scoped to have three parts:

  1. local pypi mirror

Working with python requires access to a pypi repository. Without internet access, this is not possible.

  1. local ubuntu apt-get server

Similarly, working with an ubuntu image commonly requires ubuntu packages. Having an alternative apt service with a populated cache would make this possible.

  1. local yum repo

The same applies to working with Centos and yum packages.

Todo

pypi

Initial single-host implementation
