+
+Create a redis service
+======================
+
+.. include:: example_header.inc
+
+Here's an example of using data volumes to share the same data between 2 couchdb containers.
+This could be used for hot upgrades, testing different versions of couchdb on the same data, etc.
+
+Create first database
+---------------------
+
+Note that we're marking /var/lib/couchdb as a data volume.
+
+.. code-block:: bash
+
+    COUCH1=$(docker run -d -v /var/lib/couchdb shykes/couchdb:2013-05-03)
+
+Add data to the first database
+------------------------------
+
+We're assuming your docker host is reachable at `localhost`. If not, replace `localhost` with the public IP of your docker host.
+
+.. code-block:: bash
+
+    HOST=localhost
+    URL="http://$HOST:$(docker port $COUCH1 5984)/_utils/"
+    echo "Navigate to $URL in your browser, and use the couch interface to add data"
+
+Create second database
+----------------------
+
+This time, we're requesting shared access to $COUCH1's volumes.
+
+.. code-block:: bash
+
+    COUCH2=$(docker run -d -volumes-from $COUCH1) shykes/couchdb:2013-05-03)
+
+Browse data on the second database
+----------------------------------
+
+.. code-block:: bash
+
+    HOST=localhost
+    URL="http://$HOST:$(docker port $COUCH2 5984)/_utils/"
+    echo "Navigate to $URL in your browser. You should see the same data as in the first database!"
+
+Congratulations, you are running 2 Couchdb containers, completely isolated from each other *except* for their data.
