 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.

-## 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.

+## Running a Server with a Feed-The-Beast (FTB) modpack
+
+Enable this server mode by adding a `-e TYPE=FTB` to your command-line,
+but note the following additional steps needed...
+
+You need to specify a modpack to run, using the `FTB_SERVER_MOD` environment
+variable. An FTB server modpack is available together with its respective
+client modpack on https://www.feed-the-beast.com under "Additional Files."
+Because of the interactive delayed download mechanism on that web site, you
+must manually download the server modpack. Copy the modpack to the `/data`
+directory (see "Attaching data directory to host filesystem”).
+
+Now you can add a `-e FTB_SERVER_MOD=name_of_modpack.zip` to your command-line.
+
+    $ docker run -d -v /path/on/host:/data -e TYPE=FTB \
+        -e FTB_SERVER_MOD=FTBPresentsSkyfactory3Server_3.0.6.zip \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+Instead of explicitly downloading a modpack from the Feed the Beast site, you
+can you set `FTB_SERVER_MOD` to the **server** URL of a modpack, such as
+
+    $ docker run ... \
+      -e TYPE=FTB \
+      -e FTB_SERVER_MOD=https://www.feed-the-beast.com/projects/ftb-infinity-lite-1-10/files/2402889
+
+### Using the /data volume
+
+You must use a persistent `/data` mount for this type of server.
+
+To do this, you will need to attach the container's `/data` directory
+(see "Attaching data directory to host filesystem”).
+
+If the modpack is updated and you want to run the new version on your
+server, you stop and remove the container:
+
+    docker stop mc
+    docker rm mc
+
+Do not erase anything from your /data directory (unless you know of
+specific mods that have been removed from the modpack). Download the
+updated FTB server modpack and copy it to `/data`. Start a new container
+with `FTB_SERVER_MOD` specifying the updated modpack file.
+
+    $ docker run -d -v /path/on/host:/data -e TYPE=FTB \
+        -e FTB_SERVER_MOD=FTBPresentsSkyfactory3Server_3.0.7.zip \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+### FTB server JVM options
+
+An FTB server modpack contains its own startup script that launches the
+JVM and it does not use the `JVM_OPTS` environment variable. Instead
+you can use `MIN_RAM` and `MAX_RAM` variables. These are appended to
+the JVM `-Xms` and `-Xmx` options. For example, `-e MIN_RAM=2G` results
+in `-Xms2G` passed to the JVM.
+
+Additionally, `PERMGEN_SIZE` is passed on to `-XX:PermSize`. Here is an
+example:
+
+    $ docker run -d -v /path/on/host:/data -e TYPE=FTB \
+        -e MIN_RAM=1G -e MAX_RAM=2G -e PERMGEN_SIZE=512M \
+        -e FTB_SERVER_MOD=FTBPresentsSkyfactory3Server_3.0.6.zip \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+Note: The FTB server start script will also override other options,
+like `MOTD`.

+### Remove old mods/plugins

+When the option above is specified (`MODPACK`) you can also instruct script to
+delete old mods/plugins prior to installing new ones. This behaviour is desirable
+in case you want to upgrade mods/plugins from downloaded zip file.
+To use this option pass the environment variable `REMOVE_OLD_MODS="TRUE"`, such as

+**WARNING:** All content of the `mods` or `plugins` directory will be deleted

 ### Memory Limit
 
-The Java memory limit can be adjusted using the `JVM_OPTS` environment variable, where the default is
-the setting shown in the example (max and min at 1024 MB):
+By default, the image declares a Java initial and maximum memory limit of 1 GB. There are several
+ways to adjust the memory settings:
 
-    docker run -e 'JVM_OPTS=-Xmx1024M -Xms1024M' ...
+* `MEMORY`, "1G" by default, can be used to adjust both initial (`Xms`) and max (`Xmx`)
+  memory settings of the JVM
+* `INIT_MEMORY`, independently sets the initial heap size
+* `MAX_MEMORY`, independently sets the max heap size
+
+The values of all three are passed directly to the JVM and support format/units as
+`<size>[g|G|m|M|k|K]`.
 
 ### /data ownership
 
 In order to adapt to differences in `UID` and `GID` settings the entry script will attempt to correct ownership and writability of the `/data` directory. This logic can be disabled by setting `-e SKIP_OWNERSHIP_FIX=TRUE`.
+
+### JVM Options
+
+General JVM options can be passed to the Minecraft Server invocation by passing a `JVM_OPTS`
+environment variable. Options like `-X` that need to proceed general JVM options can be passed
+via a `JVM_XX_OPTS` environment variable.
