KubeCon offered “Lightning Talks”, which were quick lectures meant to get right to the point and provide the audience with helpful knowledge ranging from troubleshooting tips, to
how to donate projects to the CNCF, and everything in-between. The first video shown below diagrams
DNS of a K8s cluster, and common areas that misbehave. It also shows the importance of
observability in a cluster to identify potential problem areas. The next video demonstrates simple yet effective ways to
increase productivity in the CLI using aliases and tab completion.
