kubectl-tree

A kubectl plugin to visualize Kubernetes resource relationships in a tree-like format.

Overview

kubectl-tree helps you understand the relationships between Kubernetes resources in your cluster. It shows a hierarchical view of:

• Workloads (Deployments, StatefulSets, DaemonSets)
• Their child resources (ReplicaSets, Pods)
• Related resources (Services, ConfigMaps, Secrets, PVCs)
• Containers within Pods (Containers, InitContainers)

Examples

kubectl tree -n istio-system
