dup - kubectl Plugin for duplication of Kubernetes Resources

This plugin is designed for on-the-fly duplication of Kubernetes resources. It focuses on providing a convenient way to edit resources before duplication, with a specific emphasis on Pods to create a fine-tuned resource quickly. This tool can be used for debugging running containers without them crashing, and simplifying the administration and general interaction with Kubernetes clusters.
