-Docker configuration files for ceph setups
+## Example Setup
+
+### Create fake volumes on the host
+```
+dd if=/dev/zero of=/tmp/ceph0 bs=1024000 count=3000
+mkfs.ext4 /tmp/ceph0
+mkdir /tmp/ceph0d
+sudo mount -o loop /tmp/ceph0 /tmp/ceph0d
+```
+```
+dd if=/dev/zero of=/tmp/ceph1 bs=1024000 count=3000
+mkfs.ext4 /tmp/ceph1
+mkdir /tmp/ceph1d
+sudo mount -o loop /tmp/ceph1 /tmp/ceph1d
+```
+
+### Build the docker image
+```
+sudo docker build -t ceph .
+```
+
+### Create and run a new container instance
+```
+sudo docker run -h cephbox -i -v /tmp/ceph0d:/var/lib/ceph/osd/ceph-0 -v /tmp/ceph1d:/var/lib/ceph/osd/ceph-1 -p 6789:6789 -t ceph /bin/bash
+./bootstrap.sh
+```
+
+This will give you a shell inside the container.
+
+### Validation
+From the given shell inside the container, check the network information:
+```
+ifconfig
+...
+inet addr:172.17.0.15  Bcast:172.17.255.255  Mask:255.255.0.0
+...
+```
+and the client.admin key you'll need to configure the client:
+```
+ceph auth list
+...
+client.admin
+	key: AQDeKstSIC6GMBAAAmE0rOLITNzDXd8XcH+yaw==
+...
+```
+Do not exit this shell (that would stop the container).
+
+From another shell, configure your client:
+```
+sudo vim /etc/ceph/ceph.conf
+[global]
+mon_initial_members = cephbox
+mon_host = 172.17.0.15
+```
+```
+sudo vim /etc/ceph/keyring
+[client.admin]
+	key = AQDeKstSIC6GMBAAAmE0rOLITNzDXd8XcH+yaw==
+```
+
+Finally, check the health of the cluster, running the following from the host:
+```
+ceph health
+HEALTH_OK
+```
+
