One of the strengths of Kubernetes is its flexibility and range of configuration possibilities along with the API-driven, programmable configuration mechanisms and command-line visibility and control using manifest files. However, that strength can also be a weakness: when deployments are complex or when managing multiple clusters, it can be difficult to get a clear picture of the overall status through command-line arguments and manifests alone. Lens attempts to solve this problem with an integrated environment for viewing the current state of the cluster and its workloads, visualizing cluster metrics and changing configurations through an embedded text editor. Rather than a simple point-and-click interface, Lens brings together the tools an administrator would run from the command line into a single, navigable interface. This tool is one of several approaches that are trying to tame the complexity of Kubernetes management. We've yet to see a clear winner in this space, but Lens strikes an interesting balance between a graphical UI and command-line–only tools.
