The following .travis.yml file contains the new code for building docker images that are tagged with build number. It also contains code to deploy to the AWS k8s cluster that we have running. You will need it for the next lecture:

dist: trusty
sudo: required
services:
 - docker

# Install latest Docker CE so we can use Dockerfile outside build context
addons:
 apt:
   packages:
