In a windows pod template, add a host path volume, and specify a net pipe for host and mount paths.  Example: \\.\pipe\docker_engine

The generated pod yaml will convert the backslashes to forward slashes, and Kubernetes will change the mount path to: //./pipe/docker_engine

Kubernetes pod fails to create container with the following:

Error: Error response from daemon: invalid volume specification: '\\.\pipe\docker_engine:c://./pipe/docker_engine'

Workaround for this is to use the following override yaml in the pod template:

spec:
  volumes:
    - name: docker-pipe
      hostPath:
        path: \\.\pipe\docker_engine
  containers:
    - name: jnlp
      volumeMounts:
        - name: docker-pipe
          mountPath: \\.\pipe\docker_engine
