In my current work, I spend a lot of time with keptn – an Open Source Control Plane for Continuous Deployment and Automated Operations. I deployed keptn on a GKE cluster and it's been running there for the past couple of weeks. I have been using it at my current tour through different conferences (Devoxx, Confitura) and meetups, (Cloud Native, KraQA, Trojmiasto Java UG) where I've promoted keptn. If you want to know more about keptn, I encourage you to check out www.keptn.sh, "What is keptn and how to get started" (blog), "Getting started with keptn" (YouTube) or my slides on Shipping Code like a keptn.
