Preview build: Container grouping and stack composition

NOTE: this is out of date - refer to moby/moby#9694

Here is a preview build of two new features we’re working on concurrently: container grouping (docker groups) and stack composition (docker up). Together, they will eventually form a complete replacement for Fig.

The error looks like this?

Bundler::GemNotFound: Could not find jumpup-heroku-0.0.1.gem for installation
An error occurred while installing jumpup-heroku (0.0.1), and Bundler cannot continue.
Make sure that `gem install jumpup-heroku -v '0.0.1'` succeeds before bundling.

How to run only the broken integration task:

TLDR: I now add the following snippet to all my Dockerfiles:

# If host is running squid-deb-proxy on port 8000, populate /etc/apt/apt.conf.d/30proxy
# By default, squid-deb-proxy 403s unknown sources, so apt shouldn't proxy ppa.launchpad.net
RUN route -n | awk '/^0.0.0.0/ {print $2}' > /tmp/host_ip.txt
RUN echo "HEAD /" | nc `cat /tmp/host_ip.txt` 8000 | grep squid-deb-proxy \
  && (echo "Acquire::http::Proxy \"http://$(cat /tmp/host_ip.txt):8000\";" > /etc/apt/apt.conf.d/30proxy) \
  && (echo "Acquire::http::Proxy::ppa.launchpad.net DIRECT;" >> /etc/apt/apt.conf.d/30proxy) \
  || echo "No squid-deb-proxy detected on docker host"

Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

• Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
• Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
• Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)
