3 About this workshop Speed matters. CI/CD is a key component to improving the speed, quality and security of the overall software delivery process and being able to optimize and get the most out of your CI/CD tool will take development velocity from good to great. In this workshop I will provide a deep-dive into a variety of advanced techniques for making your pipelines run faster as well as improve quality and security. The workshop will share practical examples as well as a live demo. We will be closing the session with a Ask Me Anything Q&A.

22 Debugging with SSH The best way to troubleshoot problems is to securely debug problems within the job environment - while it’s running. Without SSH access to the build environment, a developer has to try to replicate the CI/CD environment in their dev environment in order to accurately identify the issue, then attempt to resolve it using only application, stack trace, and system logs. These types of situations are a huge waste of time for developers and SRE teams.
23 Debugging with SSH - Results & Resources Resources: Angel Rivera - Debugging CI/CD Pipelines with SSH Artem Zakharchenko - Efficient CircleCI Debugging with SSH Quotes: “In my mind, CircleCI has always had the edge because of a single feature: SSH support. SSH access to jobs is really good for debugging tricky build or deploy problems...On some of the consultancy engagements I’ve worked on, this remote SSH access feels like has saved hours or even days of trial-and-error troubleshooting. Out of the box, GitHub Actions doesn’t offer the same ability to debug build problems.” - Paul Elliott, Consultant at The Scale Factory - source “Another benefit of using CircleCI is that its interactive debugging is straightforward and secure. No tokens, exposed secrets, or complex setup steps. If you don’t have Docker installed on your local machine, it is still convenient to debug CircleCI remotely. Unlike for Travis CI, it is completely secure. Unlike AppVeyor, it is easy to setup.” - John Blischak, Freelance Software Developer - source
25 Test Splitting “Any time a developer spends waiting for tests to run is time not spent writing the next piece of code, not to mention the cost of waiting around and losing context on what they’re working on. Fast feedback is everything.” - Rob Zuber One of the easiest ways to speed up builds on CircleCI is with test splitting. Particularly, splitting tests by timing data.The CircleCI test splitting mechanism takes in a list of tests and splits those tests across the number of nodes defined by the parallelism key.
26 Customer Examples: Amio - Testing times decreased from 15mins to 9mins (40% decrease) - source Zygo - Testing times decreased from 40mins to less than 10 mins (70% decrease) - source Kogan.com - Testing times decreased from 25mins to less than 5 mins (80% decrease) - source Bolt - Testing times decreased from 15mins to less than 5 mins (33% decrease) - source Resources: Rob Zuber - Intelligent CI/CD with CircleCI: Test Splitting Ryan Pedersen - A Guide to Test Splitting Test Splitting - Results & Resources “Where CircleCI is different from other systems is their CLI tool will split your test suite for you, in a deterministic way, and distribute your test suite evenly over the number of executors you’ve declared. Most interestingly, is the test suite can be split by timing data so that each of your executors should have a fairly consistent run time. And, true to their word, we were able to get our test suite run time down to under 5 minutes.” - Josh Smeaton, Kogan.com
