A web-based, highly extensible platform for developers to better understand the complexity of Kubernetes clusters.
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.
Graphically visualizate relationships between objects in a Kubernetes cluster. The status of individual objects are represented by color to show workload performance.
Consolidated status and configuration information in a single page aggregated from output typically found using multiple kubectl commands.
Forward a local port to a running pod with a single button for debugging applications and even port forward multiple pods across namespaces.
View log streams of pod and container activity for troubleshooting or monitoring without holding multiple terminals open.
Organize workloads with label filtering for inspecting clusters with a high volume of objects in a namespace.
Easily change between namespaces or contexts across different clusters. Multiple kubeconfig files are also supported.
Highly extensible plugin system for users to provide additional functionality through gRPC. Plugin authors can add components on top of existing views.

For configuring Octant, setting up a development environment, or running tests, refer to the documentation here.
Plugins are a core part of Octant in the Kubernetes ecosystem. A plugin can read objects and allows users to add components to Octant's views.
An example plugin can be found in
cmd/octant-sample-plugin and installed to the default plugin path with
