Deploy CephFS on kubernetes with rook
-------------------------------------

.. code-block:: bash

    $ mkdir rook
    $ cd rook
    $ wget https://raw.githubusercontent.com/rook/rook/master/cluster/examples/kubernetes/ceph/operator.yaml
    $ wget https://raw.githubusercontent.com/rook/rook/master/cluster/examples/kubernetes/ceph/cluster.yaml

To disable TLS, edit ``cluster.yaml`` file:

.. code-block:: yaml

  dashboard:
    enabled: true
    # serve the dashboard under a subpath (useful when you are accessing the dashboard via a reverse proxy)
    # urlPrefix: /ceph-dashboard
    # serve the dashboard at the given port.
    # port: 8443
    # serve the dashboard using SSL
    ssl: false

Ingress file, ``ingress.yaml``:

.. code-block:: yaml

    apiVersion: extensions/v1beta1
    kind: Ingress
    metadata:
      name: rook-ceph-mgr-dashboard
      namespace: rook-ceph
      annotations:
        kubernetes.io/ingress.class: "nginx"
      rules:
      - host: rook-ceph.example.com
        http:
          paths:
          - path: /
            backend:
              serviceName: rook-ceph-mgr-dashboard
              servicePort: 8443


.. code-block:: bash

    $ kubectl create -f operator.yaml
    $ kubectl create -f cluster.yaml
    $ kubectl create -f ingress.yaml


.. code-block:: bash

    $ kubectl -n rook-ceph get pod
