Speeding up Travis CI with Containers

Another quick Travis CI post. Travis CI now supports containers, which means potentially faster builds. There are two lines you can add to your .travis.yml:

sudo: false
cache: bundler

The first enables the container infrastructure. The second caches dependencies for a Ruby project. Travis CI has articles on the new architecture and caching content and dependencies that provide more detail if you need it. I didn’t see as much of a speedup with caching, but enabling containers definitely made it faster.
