This is a very thin device plugin which just exposing device files in host to containers.

Those device files are assumed to be non limited resources, things like "capabilitites" of a host (i.e. /dev/kvm).

However, due to kubernetes/kubernetes#59380, current device plugin(v1beta1) doesn't support unlimited extended resources. Currently a hack would be to set the number of resources advertised by the device plugin to a very high mumber.

cd example

# create configmap with key=`config.json`, value=config json
# this config
#   - resource name: github.com/everpeace-random
#   - host device file: /dev/random
#   - container path to be mounted: /dev/everpeace-mount
#   - permission: "r"
#   - number of devices:  100  # please make this value sufficiently large,
#                              # in this case, capacity is `github.com/everpeace-random: 100`
kubectl create -f host-devices.yaml

# deploy device plugin
kubectl create -f host-device-plugin.yaml

# create test pod
# this requests 10 everpeace-random resources. (10 is meaningless.)
kubectl create -f test-pod.yaml
