   Error: could not start OpenShift container "origin"

     Use "openshift options" for a list of global command-line options (applies to all commands).

With docker logs:

# docker logs origin

Usage:
  openshift start node [options]

Options:
      --bootstrap-config-name='': On startup, the node will request a client cert from the master and get its config from this config map in the openshift-node namespace (experimental).
      --config='': Location of the node configuration file to run from. When running from a configuration file, all other command-line arguments are ignored.
      --disable='': The set of node components to disable
      --enable='dns,kubelet,plugins,proxy': The set of node components to enable
      --expire-days=730: Validity of the certificates in days (defaults to 2 years). WARNING: extending this above default value is highly discouraged.
      --hostname='veras': The hostname to identify this node with the master.
      --images='openshift/origin-${component}:${version}': When fetching images used by the cluster for important components, use this format on both master and nodes. The latest release will be used by default.
      --kubeconfig='': Path to the kubeconfig file to use for requests to the Kubernetes API.
      --kubernetes='https://localhost:8443': removed in favor of --kubeconfig

Using runliketo reverse the command line use to start the container:

# runlike origin
docker run --name=origin --hostname=veras --env="HOME=/root" --env="OPENSHIFT_CONTAINERIZED=true" --env="KUBECONFIG=/var/lib/origin/openshift.local.config/master/admin.kubeconfig" --env="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" --volume="/var/log:/var/log:rw" --volume="/var/run:/var/run:rw" --volume="/sys:/sys:rw" --volume="/sys/fs/cgroup:/sys/fs/cgroup:rw" --volume="/dev:/dev" --volume="/:/rootfs:ro" --volume="/var/lib/origin/openshift.local.volumes:/var/lib/origin/openshift.local.volumes:rslave" --network=host --privileged --restart= --label io.openshift.tags="openshift,core" --label license="GPLv2" --label io.k8s.description="OpenShift Origin is a platform for developing, building, and deploying containerized applications." --label build-date="20170911" --label name="CentOS Base Image" --label io.k8s.display-name="OpenShift Origin Application Platform" --label vendor="CentOS" --detach=true openshift/origin:v3.7.0-rc.0 start node --bootstrap --kubeconfig=/var/lib/origin/openshift.local.config/node/node-bootstrap.kubeconfig --loglevel=4

Expected Result

The node container should start without this help message.
