Over those past two years we’ve deployed a new platform based on Kubernetes for developing, testing and deploying XING's applications. Today most of our workloads run on this platform but the road sometimes felt a bit bumpy. From misconfiguration, to software bugs in the Kubernetes ecosystem or even Kernel race conditions, we encountered a variety of problems. In this talk we will discuss some of those issues and how we fixed, mitigated or worked around them.
