kubectl tree

A kubectl plugin to explore ownership relationships between Kubernetes objects through ownersReferences on the objects.

The kubectl lineage plugin is very similar to kubectl tree, but it understands logical relationships between some API objects without needing ownerReferences.

Installation

Use krew plugin manager to install:

kubectl krew install tree
kubectl tree --help

Demo

Example (Deployment):

example Kubernetes deployment object hierarchy

Example (Knative Service):

example Kubernetes object hierarchy with Knative Service

Example (Agones Fleet):

example Kubernetes object hierarchy with Agones Fleet

Flags

By default, the plugin will only search "namespaced" objects in the same namespace as the specified object.

You can use the -A or --all-namespaces flag to search namespaced and non-namespaced objects in all namespaces.
