Kelsey Hightower, a Google Developer Advocate and Google Cloud Platform evangelist, recently gave a very helpful screencast demonstrating some of the tips & tricks he uses when developing Go microservices for Kubernetes & docker. Among other things, he recommends being very verbose during the initialization of your app by outputting environment variables and port bindings. He also raises the important distinction between readiness probes and liveness probes and when to use them. Lastly, in the Q&A he explains why it's advantageous to use resource files instead of editing live configurations because the former fits better in to a pull-request workflow that many companies already use as part of the CI/CD pipeline.
