Lightweight Spree testing and deployment with Wercker and Heroku

Deploying Spree stores doesn't have to be scary. This lightning talk demonstrates a way to get immediate testing and deployment of every line of code committed to your application. Sleep easy with the knowledge that your deployment process is tested and executed daily instead of just once before a big rollout.

1. Continuous Integration + Deployment for Spree with Wercker (and Heroku!)
2. 2 Hi, I'm Daniel • Application developer at Coroutine in Memphis, Tennessee • Working with Spree since last April • Approaching go-live on our second Spree store
3. 3 Keeping the Spree team busy (sorry!)
4. 4 Case Study: Tube Depot • Devs in different time zones • Spree customizations needed to be tested and refined quickly • No full-time sysadmin
5. 5 CI + CD + Heroku • CI: New code is automatically tested. Failures are immediately communicated to the dev team. • CD: Passing CI builds are automatically deployed... somewhere • Heroku (or Ninefold maybe?): Platform as a service application hosting. Database, logging, caching, analytics, mailing, error tracking, background jobs. Snapshotted deploys for quick rollbacks!
6. 6 But why? • Immediate feedback makes it harder to break the build or introduce conflicting designs • Increases developer confidence, especially when they're not colocated • Stakeholders always have a working, clickable copy of the latest edition of the store • Dramatically less effort and risk involved in deployment means more deployments, more feedback, and a better storefront
7. 7 Spree's CI: ci.spree.fm
8. 8 Spree's .travis.yml
9. 9 Spree stores with Wercker
10. 10 wercker.yml
11. 11 Multiple deploy targets
12. 12 Deployment variables
13. 13 Results: Successful go-live!
