      Octant is a tool for developers to understand how applications run on a
      Kubernetes cluster.
      It aims to be part of the developer's toolkit for gaining insight and
      approaching complexity found in Kubernetes. Octant offers a combination of
      introspective tooling, cluster navigation, and object management along
      with a plugin system to further extend its capabilities.
