Using Device Manager

Enabling Device Manager

Enable Device Manager to implement a device plug-in to advertise specialized hardware without any upstream code changes.

  1. Enable Device Manager support on the target node or nodes:

    $ oc describe configmaps <name>

    For example:

    $ oc describe configmaps node-config-infra
...
kubeletArguments:
...
  feature-gates:
  - DevicePlugins=true

  2. Ensure that Device Manager was actually enabled by confirming that /var/lib/kubelet/device-plugins/kubelet.sock is created on the node. This is the UNIX domain socket on which the Device Manager gRPC server listens for new plug-in registrations. This sock file is created when the Kubelet is started only if Device Manager is enabled.
