 Using the Docker Compose file above, a value of `2` is appropriate when scaling the cluster to 3 master nodes:
 
     docker-compose scale master=3
+
+## Auto transport/http discovery with Swarm Mode
+
+When using Docker Swarm mode (starting with 1.12), the overlay and ingress network interfaces are assigned
+multiple IP addresses. As a result, it creates confusion for the transport publish logic even when using
+the special value `_eth0_`.
+
+To resolve this, add
+
+    -e DISCOVER_TRANSPORT_IP=eth0
+
+replacing `eth0` with another interface within the container, if needed.
+
+The same can be done for publish/binding of the http module by adding:
+
+    -e DISCOVERY_HTTP_IP=eth2
+
+## Heap size and other JVM options
+
+By default this image will run Elasticsearch with a Java heap size of 1 GB. If that value
+or any other JVM options need to be adjusted, then replace the `ES_JAVA_OPTS`
+environment variable.
+
+For example, this would allow for the use of 16 GB of heap:
+
+    -e ES_JAVA_OPTS="-Xms16g -Xmx16g"
+
+Refer to [this page](https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html)
+for more information about why both the minimum and maximum sizes were set to
+the same value.
