A Quick overview and install in less than 5 minutes

Definition From the Docs :

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.

Octant is one of the recent projects by VMware that aims to simplify the kubernetes view for developers. Now the developers would be able to see what all is happening in the cluster when they are deploying their workloads.
Let us setup Octant on a Katakoda cluster and see what all capabilities it provides out of the box to the Developers.
