## Enable container accelertion feature, for example use gpu acceleration in containers

## Nvidia GPU driver install. Install will by done by a (init) pod running as a daemonset.
## Important: if you use Ubuntu then you should set in all.yml 'docker_storage_options: -s overlay2'
## Array with nvida_gpu_nodes, leave empty or comment if you dont't want to install drivers.
## Labels and taints won't be set to nodes if they are not in the array.
# nvidia_gpu_nodes:
# - kube-gpu-001
# nvidia_driver_version: "384.111"
## flavor can be tesla or gtx
# nvidia_gpu_flavor: gtx
