$ 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:
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
