k8s-resource-summarizer is an interactive tool that allows selecting Kubernetes contexts and namespaces, listing pods, and summarizing their CPU and memory resources. This tool is useful for administrators and developers who need a quick and consolidated view of resource usage in their Kubernetes clusters.

• Selection of Kubernetes contexts from the kube-config file.
• Selection of namespaces, with default option for astarte if available.
• Listing of pods with details of their CPU and memory resources.
• Summarization of CPU and memory resources of all listed pods.

• Python 3.x
• Kubernetes client (kubernetes package)
• pick library for interactive menus
