You've spent the time designing, architecting, setting up, and configuring your Kubernetes cluster. Now, it's on to day two. "Day two" refers to the functions of scaling, optimizing, monitoring, securing, and in general keeping the lights on. In this talk, we discuss the tools that you have available to help you build a reliable and resilient Kubernetes cluster and run workloads in production. We discuss how to control the network, secure your environment using threat detection, scan your containers for vulnerabilities, use monitoring tools, and create scalable containers and clusters.
