 This Docker image provides an easily configurable Elasticsearch node. Via port mappings, it is easy to create an arbitrarily sized cluster of nodes. As long as the versions match, you can mix-and-match "real" Elasticsearch nodes with container-ized ones.

-Elasticsearch 5.x requires that the virtual memory mmap count is set sufficiently for stable,

-## Multiple Network Binding, such as Swarm Mode
+## Auto transport/http discovery with Swarm Mode
 
-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`.
+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_`.
 
-That discovery can be overridden by providing a specific ethernet device name
-to `DISCOVER_TRANSPORT_IP` and/or `DISCOVER_HTTP_IP`, such as
+To resolve this, add
 
     -e DISCOVER_TRANSPORT_IP=eth0
-    -e DISCOVER_HTTP_IP=eth2
 
-## Heap size and other JVM options
+replacing `eth0` with another interface within the container, if needed.
 
-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.
+The same can be done for publish/binding of the http module by adding:
 
-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.
