-## Auto transport/http discovery with Swarm Mode
+## Multiple Network Binding, such as 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_`.
+When using Docker Swarm mode the container is presented with multiple ethernet
+devices. By default, all global, routable IP addresses are configured for
+Elasticsearch to use as `network.host`.
 
-To resolve this, add
+That discovery can be overridden by providing a specific ethernet device name
+to `DISCOVER_TRANSPORT_IP` and/or `DISCOVER_HTTP_IP`, such as
 
     -e DISCOVER_TRANSPORT_IP=eth0
+    -e DISCOVER_HTTP_IP=eth2
 
-replacing `eth0` with another interface within the container, if needed.
+## Heap size and other JVM options
 
-The same can be done for publish/binding of the http module by adding:
+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.
 
-    -e DISCOVERY_HTTP_IP=eth2
+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.
