+```
+
+As you can see, there is also a Kibana instance included and available at port 5601.
+
+# Health Checks
+
+This container declares a [HEALTHCHECK](https://docs.docker.com/engine/reference/builder/#/healthcheck) that queries the `_cat/health`
+endpoint for a quick, one-line gauge of health every 30 seconds.
+
+The current health of the container is shown in the `STATUS` column of `docker ps`, such as
+
+    Up 14 minutes (healthy)
+
+You can also check the history of health checks from `inspect`, such as:
+
+```
+> docker inspect -f "{{json .State.Health}}" es
+{"Status":"healthy","FailingStreak":0,"Log":[...
+```
+
+# Configuration Summary
+
+## Ports
+
+* `9200` - HTTP REST
+* `9300` - Native transport
+
+## Volumes
+
+* `/data` - location of `path.data`
+* `/conf` - location of `path.conf`
+
+# Configuration Details
+
+The following configuration options are specified using `docker run` environment variables (`-e`) like
 
     docker run ... -e NAME=VALUE ... itzg/elasticsearch
 
+Since Docker's `-e` settings are baked into the container definition, this image provides an extra feature to change any of the settings below for an existing container. Either create/edit the file `env` in the `/conf` volume mapping or edit within the running container's context using:
+
+    docker exec -it CONTAINER_ID vi /conf/env
+
+replacing `CONTAINER_ID` with the container's ID or name.
+
+The contents of the `/conf/env` file are standard shell
+
+    NAME=VALUE
+
+entries where `NAME` is one of the variables described below.
+
+Configuration options not explicitly supported below can be specified via the `OPTS` environment variable. For example, by default `OPTS` is set with
+
+    OPTS=-Dnetwork.bind_host=_non_loopback_
+
+_NOTE: That option is a default since `bind_host` defaults to `localhost` as of 2.0, which isn't helpful for
+port mapping out from the container_.

+## Node Type
+
+If you refer to [the Node section](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/modules-node.html)
+of the Elasticsearch reference guide, you'll find that there's three main types of nodes: master-eligible, data, and client.
+
+In larger clusters it is important to dedicate a small number (>= 3) of master nodes. There are also cases where a large cluster may need dedicated gateway nodes that are neither master nor data nodes and purely operate as "smart routers" and have large amounts of CPU and memory to handle client requests and search-reduce.
+
+To simplify all that, this image provides a `TYPE` variable to let you amongst these combinations. The choices are:
+
+* (not set, the default) : the default node type which is both master-eligible and a data node
+* `MASTER` : master-eligible, but holds no data. It is good to have three or more of these in a
+large cluster
+* `DATA` (or `NON_MASTER`) : holds data and serves search/index requests. Scale these out for elastic-y goodness.
+* `GATEWAY` (or `COORDINATING`) : only operates as a client node or a "smart router". These are the ones whose HTTP port 9200 will need to be exposed
+* `INGEST` : operates only as an ingest node and is not master or data eligble
+
+A [Docker Compose](https://docs.docker.com/compose/overview/) file will serve as a good example of these three node types:
+
+```
+version: '3'
+
+services:
+  gateway:
+    image: itzg/elasticsearch
+    environment:
+      UNICAST_HOSTS: master
+      TYPE: GATEWAY
+    ports:
+      - "9200:9200"
+
+  master:
+    image: itzg/elasticsearch
+    environment:
+      UNICAST_HOSTS: gateway
+      TYPE: MASTER
+      MIN_MASTERS: 2
+
+  data:
+    image: itzg/elasticsearch
+    environment:
+      UNICAST_HOSTS: master,gateway
+      TYPE: DATA
+
+  kibana:
+    image: kibana
+    ports:
+      - "5601:5601"
+    environment:
+      ELASTICSEARCH_URL: http://gateway:9200
+
+```
+
+## Minimum Master Nodes
+
+In combination with the `TYPE` variable above, you will also want to configure the minimum master nodes to [avoid split-brain](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/modules-node.html#split-brain) during network outages.
+
+The minimum, which can be calculated as `(master_eligible_nodes / 2) + 1`, can be set with the `MIN_MASTERS` variable.
+
+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
+
+## Multiple Network Binding, such as 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`.
+
+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
+
+## 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.

+Provides a ready-to-use instance of [GitBlit](http://gitblit.com/).
 
-    docker run -d -p 80:80 p 443:443 -v /tmp/gitblit-data:/data --name gitblit itzg/gitblit
+## Basic usage
 
+Start the GitBlit container using
+
+    docker run -d -p 80:80 -p 443:443 --name gitblit itzg/gitblit
+
+Access its web interface at the mapped HTTP (80) or HTTPS (443) port of the
+Docker host. Login with the default credentials __admin__ / __admin__ .
+
+
+## Data volume
+
+In order to allow for future upgrades, run the container with a volume mount of `/data`, such as:
+
+    -v /tmp/gitblit-data:/data
+
+## Initial repository creation
+
+As a convenience for cluster configuration management with git
+(such as with [Spring Cloud Config](https://cloud.spring.io/spring-cloud-config/)),
+you may specify the name of an initial repository to be owned by the 'admin' user.
+This can be enabled by passing the name of that repository via the environment
+variable `GITBLIT_INITIAL_REPO`, such as
+
+    -e GITBLIT_INITIAL_REPO=default
+
+## Create repositories with content
+
+In addition to the approach above, you can push repostories with existing
+content by attaching them to sub-directories of `/repos`, such as
+
+    docker run -v $HOME/git/example:/repos/example ...
+
+## Custom configuration
+
+You can add or override any of the `*.properties` files for configuring GitBlit,
+typically `gitblit.properties`, by placing those files in a volume attached at
+`/config`, such as
+
+    -v $(pwd)/extra-config:/config
+
+The property files in that configuration directory will be renamed with the
+suffix `.applied` to avoid overwriting manually modified configuration on
+the next container startup.

+
+__NOTE: to avoid pegging the CPU when running Spigot,__ you will need to
+pass `--noconsole` at the very end of the command line and not use `-it`. For example,

+
+## 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`.
+
+## Using Docker Compose
+
+Rather than type the server options below, the port mappings above, etc
+every time you want to create new Minecraft server, you can now use
+[Docker Compose](https://docs.docker.com/compose/). Start with a
+`docker-compose.yml` file like the following:
+
+```
+minecraft-server:
+  ports:
+    - "25565:25565"
+
+  environment:
+    EULA: "TRUE"
+
+  image: itzg/minecraft-server
+
+  container_name: mc
+
+  tty: true
+  stdin_open: true
+  restart: always
+```
+
+and in the same directory as that file run
+
+    docker-compose up -d
+
+Now, go play...or adjust the  `environment` section to configure
+this server instance.

+* AMPLIFIED

 ### World Save Name
 
 You can either switch between world saves or run multiple containers with different saves by using the `LEVEL` option,
 where the default is "world":

+    docker run -d -e LEVEL=bonus ...
 
 **NOTE:** if running multiple containers be sure to either specify a different `-v` host directory for each
 `LEVEL` in use or don't use `-v` and the container's filesystem will keep things encapsulated.
 
-## JVM Configuration
+### Downloadable world
+
+Instead of mounting the `/data` volume, you can instead specify the URL of
+a ZIP file containing an archived world.  This will be downloaded, and
+unpacked in the `/data` directory; if it does not contain a subdirectory
+called `world/` then it will be searched for a file `level.dat` and the
+containing subdirectory renamed to `world`.  This means that most of the
+archived Minecraft worlds downloadable from the Internet will already be in
+the correct format.
+
+The ZIP file may also contain a `server.properties` file and `modules`
+directory, if required.
+
+    docker run -d -e WORLD=http://www.example.com/worlds/MySave.zip ...
+
+**NOTE:** Unless you also mount `/data` as an external volume, this world
+will be deleted when the container is deleted.
+
+**NOTE:** This URL must be accessible from inside the container.  Therefore,
+you should use an IP address or a globally resolveable FQDN, or else the
+name of a linked container.
+
+### Downloadable mod/plugin pack for Forge, Bukkit, and Spigot Servers
+
+Like the `WORLD` option above, you can specify the URL of a "mod pack"
+to download and install into `mods` for Forge or `plugins` for Bukkit/Spigot.
+To use this option pass the environment variable `MODPACK`, such as
+
+    docker run -d -e MODPACK=http://www.example.com/mods/modpack.zip ...
+
+**NOTE:** The referenced URL must be a zip file with one or more jar files at the
+top level of the zip archive. Make sure the jars are compatible with the
+particular `TYPE` of server you are running.
+
+### Online mode
+
+By default, server checks connecting players against Minecraft's account database. If you want to create an offline server or your server is not connected to the internet, you can disable the server to try connecting to minecraft.net to authenticate players with environment variable `ONLINE_MODE`, like this
+
+    docker run -d -e ONLINE_MODE=FALSE ...
+
+## Miscellaneous Options
 
 ### 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`.
