What is kubeconfig?
A YAML file storing cluster connection details, credentials, and contexts for kubectl.
A kubeconfig file (default: ~/.kube/config) tells kubectl how to connect to one or more Kubernetes clusters. It contains clusters (API server endpoint, CA cert), users (credentials: client cert, token, or exec plugin), and contexts (a named combination of cluster + user + namespace). Multiple kubeconfigs can be merged using the KUBECONFIG env variable. Tools like kubectx and kubens make switching contexts and namespaces faster.
