Make it a team mate - Getting more from your CI (Ruby edition)

This was the precursor to my "Make your CI a productive team member" talk at DevConf ZA. I presented this at Jozi.rb as a dry-run. The slides don't flow as nicely as the final product, but loads of tools in here that could be useful

1. MAKE IT A TEAMMATE Getting more from your CI
7. CATALOG THE MUNDANE Enforce coding standards Track upstream frameworks Track upstream dependencies Track dependent services Check for vulnerabilities in our code
8. Mundane tasks are easily scriptable, and thus easily automated!
10. Lines of automation Low cost, low impact: place inline with existing automation Higher cost, higher impact: create new lines of automation Critical cost: place inline with existing automation and halt!
11. STATIC ANALYSIS http://spartanideas.msu.edu/2014/02/05/how-to-be-benedict-cumberbatch/
12. Simplecov Near zero cost Actionable feedback Keep it realistic
13. RuboCop Enforce style guides Based on community guides, fully customisable by you
14. Brakeman Uses static analysis to find potential security issues in your Rails applications Very fast, does not depend on your test suite
15. SandiMeter 100 lines per class 5 lines per method 4 params per method call 1 instance variable per controller action
17. Out of band work

23. Getting your hands dirty
24. (Simone Giertz)
25. Controlled updates (you do semver your dependencies, right?) $ bundle update $ rake spec
26. The crystal ball
27. How deep does the rabbit hole go? Remove ALL version constraints from Gemfile Build with next version of Ruby too Warner Bros
28. Build pipelines https://docs.go.cd/current/
29. Manual steps in pipelines? Deliver to UAT Deploy to production
30. Generate a changelog! Commits would have built up waiting for manual trigger $ git log ${PREVIOUS_SHA}..${CURRENT_SHA} Depends on useful commit message, cross referenced with JIRA (or similar) Should probably be filtered…
31. Could CI/CD help our teams towards 10x?
