What is KCG?

Kubernetes config generator is an interactive command line tool that lets you create kubeconfig files related to a service account in a given namespace. The user can interactively chose a namespace and service account from a K8 cluster. The output is a config file with token authentication that has same RBAC permissions assigned to chosen service account.

Demo

Prerequisites

Default behaviour of this tool is to look in .kube directory for config file and it should have permissions to read namespaces, secrets, and serviceaccounts at cluster level. It can also look for credentials of the K8 cluster you want to work with from Environment variable KUBECONFIG just like kubectl would.
