flannel/Documentation/minikube.yml

# This manifest is intended for dev work, so there are some differences from the "normal" manifest
#   - no namespace (make kubectl simpler)
#   - special image name (flannel-minikube)
#   - never pull the image
#   - host-gw backend (since vxlan doesn't work in minikube)
