+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.
+
+# NOTE for use on Linux hosts
+
+Elasticsearch 5.x requires that the virtual memory mmap count is set sufficiently for stable,
+production use. [Refer to this guide for more information](https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html).
+
+# Basic Usage
+
+To start an Elasticsearch data node that listens on the standard ports on your host's network interface:
+
+    docker run -d -p 9200:9200 -p 9300:9300 itzg/elasticsearch
+
+You'll then be able to connect to the Elasticsearch HTTP interface to confirm it's alive:
+
+http://DOCKERHOST:9200/
+
+    {
+      "status" : 200,
+      "name" : "Charon",
+      "version" : {
+        "number" : "1.3.5",
+        "build_hash" : "4a50e7df768fddd572f48830ae9c35e4ded86ac1",
+        "build_timestamp" : "2014-11-05T15:21:28Z",
+        "build_snapshot" : false,
+        "lucene_version" : "4.9"
+      },
+      "tagline" : "You Know, for Search"
+    }
+
+Where `DOCKERHOST` would be the actual hostname of your host running Docker.
+
+# Simple, multi-node cluster
+
+To run a multi-node cluster (3-node in this example) on a single Docker machine use:
+
+    docker run -d --name es0 -p 9200:9200                    itzg/elasticsearch
+    docker run -d --name es1 --link es0 -e UNICAST_HOSTS=es0 itzg/elasticsearch
+    docker run -d --name es2 --link es0 -e UNICAST_HOSTS=es0 itzg/elasticsearch
+
+
+and then check the cluster health, such as http://192.168.99.100:9200/_cluster/health?pretty
+
+    {
+      "cluster_name" : "elasticsearch",
+      "status" : "green",
+      "timed_out" : false,
+      "number_of_nodes" : 3,
+      "number_of_data_nodes" : 3,
+      "active_primary_shards" : 0,
+      "active_shards" : 0,
+      "relocating_shards" : 0,
+      "initializing_shards" : 0,
+      "unassigned_shards" : 0
+    }
+
+If you have a Docker Swarm cluster already initialized you can download this
+[docker-compose.yml](https://raw.githubusercontent.com/itzg/dockerfiles/master/elasticsearch/docker-compose.yml) and deploy a cluster using:
+
+    docker stack deploy -c docker-compose.yml es
+
+
+With a `docker service ls` you can confirm 1 master, 2 data, and 1 gateway nodes are running:
+
+```
+ID            NAME        MODE        REPLICAS  IMAGE
+9nwnno8hbqgk  es_kibana   replicated  1/1       kibana:latest
+f5x7nipwmvkr  es_gateway  replicated  1/1       es
+om8rly2yxylw  es_data     replicated  2/2       es
+tdvfilj370yn  es_master   replicated  1/1       es
+```
+
+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_.
+
+## Cluster Name
+
+If joining a pre-existing cluster, then you may need to specify a cluster name different than the default "elasticsearch":
+
+    -e CLUSTER=dockers
+
+## Zen Unicast Hosts
+
+When joining a multi-physical-host cluster, multicast may not be supported on the physical network. In that case, your node can reference specific one or more hosts in the cluster via the [Zen Unicast Hosts](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html#unicast) capability as a comma-separated list of `HOST:PORT` pairs:
+
+    -e UNICAST_HOSTS=HOST:PORT[,HOST:PORT]
+
+such as
+
+    -e UNICAST_HOSTS=192.168.0.100:9300
+
+## Plugins
+
+You can install one or more plugins before startup by passing a comma-separated list of plugins.
+
+    -e PLUGINS=ID[,ID]
+
+In this example, it will install the Marvel plugin
+
+    -e PLUGINS=elasticsearch/marvel/latest
+
+Many more plugins [are available here](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-plugins.html#known-plugins).
+
+## Publish As
+
+Since the container gives the Elasticsearch software an isolated perspective of its networking, it will most likely advertise its published address with a container-internal IP address. This can be overridden with a physical networking name and port using:
+
+    -e PUBLISH_AS=DOCKERHOST:9301
+
+_Author Note: I have yet to hit a case where this was actually necessary. Other
+than the cosmetic weirdness in the logs, Elasticsearch seems to be quite tolerant._
+
+## Node Name
+
+Rather than use the randomly assigned node name, you can indicate a specific one using:
+
+    -e NODE_NAME=Docker
+
+## 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.
+* `NON_DATA` : performs all duties except holding data
+* `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 eligible
+
+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.

+A self-upgrading [Jenkins CI](http://jenkins-ci.org/) server
+
+# Basic Usage
+
+To start Jenkins with the latest version:
+
+    ID=$(docker run -d -p 8080:8080 itzg/jenkins)
+
+At a later time, you can upgrade by restarting the container:
+
+    docker stop $ID
+    docker start $ID
+
+# Attaching host directory to Jenkins home directory
+
+The Jenkins home directory is attachable at `/data`, so attaching to a host volume
+would be:
+
+    ID=$(docker run -d -p 8080:8080 -v /SOME_HOST_DIR:/data itzg/jenkins
+
+# Enabling Jenkins slave agents
+
+By default, Jenkins will pick a random port to allow slave nodes launched
+by JNLP. Since Docker networking is basically a firewall, a random port
+won't work for us. Instead the fixed port **38252** was chosen (arbitrarily)
+to be exposed by the container.
+
+Launch your Jenkins container using
+
+    ID=$(docker run -d -p 8080:8080 -p 38252:38252 itzg/jenkins)
+
+and configure the port in the Global Security settings:
+
+![](http://i.imgur.com/PhQiEHy.png)
+
+# Image Parameters
+
+## Volumes
+
+* `/data` - a majority of the Jenkins content is maintained here, such as workspaces
+* `/root` - some tools, such as Maven, utilize the home directory for default repository storage
+* `/opt/jenkins` - the installed distribution is expanded here
+
+## Ports
+
+* `8080` - for the web UI
+* `38252` - for slave incoming JMX access
+
+## Environment Variables

+
+## Usage with Docker elasticsearch container
+
+This is by far the easiest and most Docker'ish way to run Kibana.
+
+Assuming you started one or more containers using something like
+
+    docker run -d --name your-es -p 9200:9200 itzg/elasticsearch
+
+Start Kibana using
+
+    docker run -d -p 5601:5601 --link your-es:es itzg/kibana
+
+Proceed to use Kibana starting from 
+[this point in the documentation](http://www.elasticsearch.org/guide/en/kibana/current/access.html)
+
+## Usage with non-Docker elasticsearch
+
+Start Kibana using
+
+    docker run -d -p 5601:5601 -e ES_URL=http://YOUR_ES:9200 itzg/kibana
+
+Replacing `http://YOUR_ES:9200` with the appropriate URL for your system.

+This image bundles the latest (1.5.x) version of Logstash with the ability to
+groom its own Elasticsearch indices.
+
+# Basic Usage
+
+To start a Logstash container, setup a directory on your host with one or more Logstash
+pipeline configurations files, called `$HOST_CONF` here, and run
+
+    docker run -d -v $HOST_CONF:/conf itzg/logstash
+
+# Accessing host logs
+
+Logstash is much more useful when it is actually processing...logs. Logs inside the container
+are non-existent, but you can attach the host machine's `/var/log` directory via the container's
+`/logs` volume:
+
+    docker run ... -v /var/log:/logs ...
+
+Keep in mind you will need to configure `file` inputs with a base path of `/logs`, such as
+
+```
+file {
+  path => ['/logs/syslog']
+  type => 'syslog'
+}
+```
+
+# Receiving input from collectd
+
+To allow for incoming [collectd](https://collectd.org/) content, **UDP** port 25826 is exposed and
+can be mapped onto the host using:
+
+    docker run ... -p 25826:25826/udp
+
+Regardless of the host port, be sure to configure the logstash input to bind at port `25826`, such
+as
+
+```

-This docker image provides a Minecraft Server that will automatically download the latest stable, latest snapshot, or any specific server version.

+
+This docker image provides a Minecraft Server that will automatically download the latest stable
+version at startup. You can also run/upgrade to any specific version or the
+latest snapshot. See the *Versions* section below for more information.
 
 To simply use the latest stable version, run
 
-    docker run -d -p 25565:25565 itzg/minecraft-server
+    docker run -d -p 25565:25565 --name mc itzg/minecraft-server
 
-where the default server port, 25565, will be exposed on your host machine.
+where the standard server port, 25565, will be exposed on your host machine.
+
+If you want to serve up multiple Minecraft servers or just use an alternate port,
+change the host-side port mapping such as
+
+    docker run -p 25566:25565 ...
+
+will serve your Minecraft server on your host's port 25566 since the `-p` syntax is
+`host-port`:`container-port`.
+
+Speaking of multiple servers, it's handy to give your containers explicit names using `--name`, such as
+
+    docker run -d -p 25565:25565 --name mc itzg/minecraft-server
+
+With that you can easily view the logs, stop, or re-start the container:
+
+    docker logs -f mc
+        ( Ctrl-C to exit logs action )
+
+    docker stop mc
+
+    docker start mc
+
+## Interacting with the server
+
+[RCON](http://wiki.vg/RCON) is enabled by default, so you can `exec` into the container to
+access the Minecraft server console:
+
+```
+docker exec -i mc rcon-cli
+```
+
+Note: The `-i` is required for interactive use of rcon-cli.
+
+To run a simple, one-shot command, such as stopping a Minecraft server, pass the command as
+arguments to `rcon-cli`, such as:
+
+```
+docker exec mc rcon-cli stop
+```
+
+_The `-i` is not needed in this case._
+
+In order to attach and interact with the Minecraft server, add `-it` when starting the container, such as
+
+    docker run -d -it -p 25565:25565 --name mc itzg/minecraft-server
+
+With that you can attach and interact at any time using
+
+    docker attach mc
+
+and then Control-p Control-q to **detach**.
+
+For remote access, configure your Docker daemon to use a `tcp` socket (such as `-H tcp://0.0.0.0:2375`)
+and attach from another machine:
+
+    docker -H $HOST:2375 attach mc
+
+Unless you're on a home/private LAN, you should [enable TLS access](https://docs.docker.com/articles/https/).
+
+## EULA Support
 
 Mojang now requires accepting the [Minecraft EULA](https://account.mojang.com/documents/minecraft_eula). To accept add
 
-	-e EULA=TRUE
+        -e EULA=TRUE
 
 such as
 
-	docker run -e EULA=TRUE -d -p 25565:25565 itzg/minecraft-server                                                                                                                                                                      
-                                                                                                                             
-                                                                                                                                                                                
-In order to persist the Minecraft data, which you *probably want to do for a real server setup*, use the `-v` argument to map a local path to the `/data' path in the container,
-                                                                                                       
-    docker run -d -v /path/on/host:/data -p 25565:25565 itzg/minecraft-server                               
-                                                                                                       
+        docker run -d -it -e EULA=TRUE -p 25565:25565 --name mc itzg/minecraft-server
+
+## Attaching data directory to host filesystem
+
+In order to readily access the Minecraft data, use the `-v` argument
+to map a directory on your host machine to the container's `/data` directory, such as:
+
+    docker run -d -v /path/on/host:/data ...
+
+When attached in this way you can stop the server, edit the configuration under your attached `/path/on/host`
+and start the server again with `docker start CONTAINERID` to pick up the new configuration.
+
+## Versions
+
 To use a different Minecraft version, pass the `VERSION` environment variable, which can have the value
-* LATEST                                  
-* SNAPSHOT                                
-* (or a specific version, such as "1.7.9")                           
-                                                                     
-For example, to use the latest snapshot:                             
-                                                                     
+
+* LATEST
+* SNAPSHOT
+* (or a specific version, such as "1.7.9")
+
+For example, to use the latest snapshot:
+
     docker run -d -e VERSION=SNAPSHOT ...
-                                                                  
-or a specific version:                                                                                                       
-                                                                                                                             
+
+or a specific version:
+
     docker run -d -e VERSION=1.7.9 ...
-                                                                                                                             
+
+## Healthcheck
+
+This image contains [Dinnerbone's mcstatus](https://github.com/Dinnerbone/mcstatus) and uses
+its `ping` command to continually check on the container's. That can be observed
+from the `STATUS` column of `docker ps`
+
+```
+CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS                                 NAMES
+b418af073764        mc                  "/start"            43 seconds ago      Up 41 seconds (healthy)   0.0.0.0:25565->25565/tcp, 25575/tcp   mc
+```
+
+You can also query the container's health in a script friendly way:
+
+```
+> docker container inspect -f "{{.State.Health.Status}}" mc
+healthy
+```
+
+Finally, since `mcstatus` is on the `PATH` you can exec into the container
+and use mcstatus directly and invoke any of its other commands:
+
+```
+> docker exec mc mcstatus localhost status
+version: v1.12 (protocol 335)
+description: "{u'text': u'A Minecraft Server Powered by Docker'}"
+players: 0/20 No players online
+```
+
+## Running a Forge Server
+
+Enable Forge server mode by adding a `-e TYPE=FORGE` to your command-line.
+By default the container will run the `RECOMMENDED` version of [Forge server](http://www.minecraftforge.net/wiki/)
+but you can also choose to run a specific version with `-e FORGEVERSION=10.13.4.1448`.
+
+    $ docker run -d -v /path/on/host:/data -e VERSION=1.7.10 \
+        -e TYPE=FORGE -e FORGEVERSION=10.13.4.1448 \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+To use a pre-downloaded Forge installer, place it in the attached `/data` directory and
+specify the name of the installer file with `FORGE_INSTALLER`, such as:
+
+    $ docker run -d -v /path/on/host:/data ... \
+        -e FORGE_INSTALLER=forge-1.11.2-13.20.0.2228-installer.jar ...
+
+To download a Forge installer from a custom location, such as your own file repository, specify
+the URL with `FORGE_INSTALLER_URL`, such as:
+
+    $ docker run -d -v /path/on/host:/data ... \
+        -e FORGE_INSTALLER_URL=http://HOST/forge-1.11.2-13.20.0.2228-installer.jar ...
+
+In both of the cases above, there is no need for the `VERSION` or `FORGEVERSION` variables.
+
+In order to add mods, you have two options.
+
+### Using the /data volume
+
+This is the easiest way if you are using a persistent `/data` mount.
+
+To do this, you will need to attach the container's `/data` directory
+(see "Attaching data directory to host filesystem”).
+Then, you can add mods to the `/path/on/host/mods` folder you chose. From the example above,
+the `/path/on/host` folder contents look like:
+
+```
+/path/on/host
+├── mods
+│   └── ... INSTALL MODS HERE ...
+├── config
+│   └── ... CONFIGURE MODS HERE ...
+├── ops.json
+├── server.properties
+├── whitelist.json
+└── ...
+```
+
+If you add mods while the container is running, you'll need to restart it to pick those
+up:
+
+    docker stop mc
+    docker start mc
+
+### Using separate mounts
+
+This is the easiest way if you are using an ephemeral `/data` filesystem,
+or downloading a world with the `WORLD` option.
+
+There are two additional volumes that can be mounted; `/mods` and `/config`.  
+Any files in either of these filesystems will be copied over to the main
+`/data` filesystem before starting Minecraft.
+
+This works well if you want to have a common set of modules in a separate
+location, but still have multiple worlds with different server requirements
+in either persistent volumes or a downloadable archive.
+
+## Running a Bukkit/Spigot server
+
+Enable Bukkit/Spigot server mode by adding a `-e TYPE=BUKKIT -e VERSION=1.8` or `-e TYPE=SPIGOT -e VERSION=1.8` to your command-line.
+
+    docker run -d -v /path/on/host:/data \
+        -e TYPE=SPIGOT -e VERSION=1.8 \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+If you are hosting your own copy of Bukkit/Spigot you can override the download URLs with:
+* -e BUKKIT_DOWNLOAD_URL=<url>
+* -e SPIGOT_DOWNLOAD_URL=<url>
+
+You can build spigot from source by adding `-e BUILD_FROM_SOURCE=true`
+
+__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,
+
+    docker run -d -v /path/on/host:/data \
+        -e TYPE=SPIGOT -e VERSION=1.8 \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server --noconsole
+
+
+You can install Bukkit plugins in two ways...
+
+### Using the /data volume
+
+This is the easiest way if you are using a persistent `/data` mount.
+
+To do this, you will need to attach the container's `/data` directory
+(see "Attaching data directory to host filesystem”).
+Then, you can add plugins to the `/path/on/host/plugins` folder you chose. From the example above,
+the `/path/on/host` folder contents look like:
+
+```
+/path/on/host
+├── plugins
+│   └── ... INSTALL PLUGINS HERE ...
+├── ops.json
+├── server.properties
+├── whitelist.json
+└── ...
+```
+
+If you add plugins while the container is running, you'll need to restart it to pick those
+up:
+
+    docker stop mc
+    docker start mc
+
+### Using separate mounts
+
+This is the easiest way if you are using an ephemeral `/data` filesystem,
+or downloading a world with the `WORLD` option.
+
+There is one additional volume that can be mounted; `/plugins`.  
+Any files in this filesystem will be copied over to the main
+`/data/plugins` filesystem before starting Minecraft.
+
+This works well if you want to have a common set of plugins in a separate
+location, but still have multiple worlds with different server requirements
+in either persistent volumes or a downloadable archive.
+
+## Running a PaperSpigot server
+
+Enable PaperSpigot server mode by adding a `-e TYPE=PAPER -e VERSION=1.9.4` to your command-line.
+
+    docker run -d -v /path/on/host:/data \
+        -e TYPE=PAPER -e VERSION=1.9.4 \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+__NOTE: to avoid pegging the CPU when running PaperSpigot,__ you will need to
+pass `--noconsole` at the very end of the command line and not use `-it`. For example,
+
+    docker run -d -v /path/on/host:/data \
+        -e TYPE=PAPER -e VERSION=1.9.4 \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server --noconsole
+
+If you are hosting your own copy of PaperSpigot you can override the download URL with:
+* -e PAPER_DOWNLOAD_URL=<url>
+
+You can install Bukkit plugins in two ways...
+
+### Using the /data volume
+
+This is the easiest way if you are using a persistent `/data` mount.
+
+To do this, you will need to attach the container's `/data` directory

+
+This works well if you want to have a common set of plugins in a separate
+location, but still have multiple worlds with different server requirements
+in either persistent volumes or a downloadable archive.
+
+## 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
+
+### Fixing "unable to launch forgemodloader"
+
+If your server's modpack fails to load with an error [like this](https://support.feed-the-beast.com/t/cant-start-crashlanding-server-unable-to-launch-forgemodloader/6028/2):
+
+    unable to launch forgemodloader
+
+then you apply a workaround by adding this to the run invocation:
+
+    -e FTB_LEGACYJAVAFIXER=true
+
+## Running a SpongeVanilla server
+
+Enable SpongeVanilla server mode by adding a `-e TYPE=SPONGEVANILLA` to your command-line.
+By default the container will run the latest `STABLE` version.
+If you want to run a specific version, you can add `-e SPONGEVERSION=1.11.2-6.1.0-BETA-19` to your command-line.
+
+    docker run -d -v /path/on/host:/data -e TYPE=SPONGEVANILLA \
+        -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+
+You can also choose to use the `EXPERIMENTAL` branch.
+Just change it with `SPONGEBRANCH`, such as:
+
+    $ docker run -d -v /path/on/host:/data ... \
+        -e TYPE=SPONGEVANILLA -e SPONGEBRANCH=EXPERIMENTAL ...
+
+## 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.    
+
+## Server configuration
+
+### Server port
+
+The server port can be set like:
+    docker run -d -e SERVER_PORT=25565 ...
+
+### Difficulty
+
+The difficulty level (default: `easy`) can be set like:
+
+    docker run -d -e DIFFICULTY=hard ...
+
+Valid values are: `peaceful`, `easy`, `normal`, and `hard`, and an
+error message will be output in the logs if it's not one of these
+values.
+
+### Whitelist Players
+
+To whitelist players for your Minecraft server, pass the Minecraft usernames separated by commas via the `WHITELIST` environment variable, such as
+
+	docker run -d -e WHITELIST=user1,user2 ...
+
+If the `WHITELIST` environment variable is not used, any user can join your Minecraft server if it's publicly accessible.
+
+### Op/Administrator Players
+
+To add more "op" (aka adminstrator) users to your Minecraft server, pass the Minecraft usernames separated by commas via the `OPS` environment variable, such as
+
+	docker run -d -e OPS=user1,user2 ...
+
+### Server icon
+
+A server icon can be configured using the `ICON` variable. The image will be automatically
+downloaded, scaled, and converted from any other image format:
+
+    docker run -d -e ICON=http://..../some/image.png ...
+
+### Rcon
+
+To use rcon use the `ENABLE_RCON` and `RCON_PASSORD` variables.
+By default rcon port will be `25575` but can easily be changed with the `RCON_PORT` variable.
+
+    docker run -d -e ENABLE_RCON=true -e RCON_PASSWORD=testing
+
+### Query
+
+Enabling this will enable the gamespy query protocol.
+By default the query port will be `25565` (UDP) but can easily be changed with the `QUERY_PORT` variable.
+
+    docker run -d -e ENABLE_QUERY=true
+
+
+### Max players
+
+By default max players is 20, you can increase this with the `MAX_PLAYERS` variable.
+
+    docker run -d -e MAX_PLAYERS=50
+
+
+### Max world size
+
+This sets the maximum possible size in blocks, expressed as a radius, that the world border can obtain.
+
+    docker run -d -e MAX_WORLD_SIZE=10000   
+
+### Allow Nether
+
+Allows players to travel to the Nether.
+
+    docker run -d -e ALLOW_NETHER=true
+
+### Announce Player Achievements
+
+Allows server to announce when a player gets an achievement.
+
+    docker run -d -e ANNOUNCE_PLAYER_ACHIEVEMENTS=true   
+
+### Enable  Command Block
+
+Enables command blocks
+
+     docker run -d -e ENABLE_COMMAND_BLOCK=true
+
+### Force Gamemode
+
+Force players to join in the default game mode.
+
+* false - Players will join in the gamemode they left in.
+* true - Players will always join in the default gamemode.
+
+    `docker run -d -e FORCE_GAMEMODE=false`
+
+### Generate Structures
+
+Defines whether structures (such as villages) will be generated.
+
+* false - Structures will not be generated in new chunks.
+* true - Structures will be generated in new chunks.
+
+    `docker run -d -e GENERATE_STRUCTURES=true`
+
+### Hardcore
+
+If set to true, players will be set to spectator mode if they die.
+
+    docker run -d -e HARDCORE=false
+
+### Snooper
+
+If set to false, the server will not send data to snoop.minecraft.net server.
+
+    docker run -d -e SNOOPER_ENABLED=false
+
+### Max Build Height
+
+The maximum height in which building is allowed.
+Terrain may still naturally generate above a low height limit.
+
+    docker run -d -e MAX_BUILD_HEIGHT=256
+
+### Max Tick Time
+
+The maximum number of milliseconds a single tick may take before the server watchdog stops the server with the message, A single server tick took 60.00 seconds (should be max 0.05); Considering it to be crashed, server will forcibly shutdown. Once this criteria is met, it calls System.exit(1).
+Setting this to -1 will disable watchdog entirely
+
+    docker run -d -e MAX_TICK_TIME=60000
+
+### Spawn Animals
+
+Determines if animals will be able to spawn.
+
+    docker run -d -e SPAWN_ANIMALS=true
+
+### Spawn Monsters
+
+Determines if monsters will be spawned.
+
+    docker run -d -e SPAWN_MONSTERS=true
+
+### Spawn NPCs
+
+Determines if villagers will be spawned.
+
+    docker run -d -e SPAWN_NPCS=true
+
+### View Distance
+Sets the amount of world data the server sends the client, measured in chunks in each direction of the player (radius, not diameter).
+It determines the server-side viewing distance.
+
+    docker run -d -e VIEW_DISTANCE=10
+
+### Level Seed
+
+If you want to create the Minecraft level with a specific seed, use `SEED`, such as
+
+    docker run -d -e SEED=1785852800490497919 ...
+
+### Game Mode
+
+By default, Minecraft servers are configured to run in Survival mode. You can
+change the mode using `MODE` where you can either provide the [standard
+numerical values](http://minecraft.gamepedia.com/Game_mode#Game_modes) or the
+shortcut values:
+
+* creative
+* survival
+* adventure
+* spectator (only for Minecraft 1.8 or later)
+
+For example:
+
+    docker run -d -e MODE=creative ...
+
+### Message of the Day
+
 The message of the day, shown below each server entry in the UI, can be changed with the `MOTD` environment variable, such as
-                                                                     
+
     docker run -d -e 'MOTD=My Server' ...
 
-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):
+If you leave it off, a default is computed from the server type and version, such as
 
-    docker run -e 'JVM_OPTS=-Xmx1024M -Xms1024M' ...
+    A Paper Minecraft Server powered by Docker
+
+when `TYPE` is `PAPER`. That way you can easily differentiate between several servers you may have started.
+
+_The example shows how to specify a server message of the day that contains spaces by putting quotes
+around the whole thing._
+
+### PVP Mode
+
+By default, servers are created with player-vs-player (PVP) mode enabled. You can disable this with the `PVP`
+environment variable set to `false`, such as
+
+    docker run -d -e PVP=false ...
+
+### Level Type and Generator Settings
+
+By default, a standard world is generated with hills, valleys, water, etc. A different level type can
+be configured by setting `LEVEL_TYPE` to
+
+* DEFAULT
+* FLAT
+* LARGEBIOMES
+* AMPLIFIED
+* CUSTOMIZED
+* BUFFET
+
+Descriptions are available at the [gamepedia](http://minecraft.gamepedia.com/Server.properties).
+
+When using a level type of `FLAT`, `CUSTOMIZED`, and `BUFFET`, you can further configure the world generator
+by passing [custom generator settings](http://minecraft.gamepedia.com/Superflat).
+**Since generator settings usually have ;'s in them, surround the -e value with a single quote, like below.**
+
+For example (just the `-e` bits):
+
+    -e LEVEL_TYPE=flat -e 'GENERATOR_SETTINGS=3;minecraft:bedrock,3*minecraft:stone,52*minecraft:sandstone;2;'
+
+### 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.
+
+### 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.
+
+### Cloning world from a container path
+
+The `WORLD` option can also be used to reference a directory that will be used
+as a source to clone the world directory.
+
+For example, the following would initially clone the world's content
+from `/worlds/basic`. Also notice in the example that you can use a
+read-only volume attachment to ensure the clone source remains pristine.
+
+```
+docker run ... -v $HOME/worlds:/worlds:ro -e WORLD=/worlds/basic 
+```
+
+### 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.
+
+### 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
+
+    docker run -d -e REMOVE_OLD_MODS="TRUE" -e MODPACK=http://www.example.com/mods/modpack.zip ...
+
+**NOTE:** This option will be taken into account only when option `MODPACK` is also used.
+
+**WARNING:** All content of the `mods` or `plugins` directory will be deleted
+before unpacking new content from the zip file.
+
+### 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 ...
+
+### Allow flight
+
+Allows users to use flight on your server while in Survival mode, if they have a mod that provides flight installed.
+
+    -e ALLOW_FLIGHT=TRUE|FALSE
+
+## Miscellaneous Options
+
+### Running as alternate user/group ID
+
+By default, the container will switch to user ID 1000 and group ID 1000;
+however, you can override those values by setting `UID` and/or `GID` as environmental entries, during the `docker run` command.
+
+    -e UID=1234
+    -e GID=1234
+
+The container will also skip user switching if the `--user`/`-u` argument
+is passed to `docker run`.
+
+### Memory Limit
+
+By default, the image declares a Java initial and maximum memory limit of 1 GB. There are several
+ways to adjust the memory settings:
+
+* `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]`.
+
+### 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.
+
+### HTTP Proxy
+
+You may configure the use of an HTTP/HTTPS proxy by passing the proxy's URL via the `PROXY`
+environment variable. In [the example compose file](docker-compose-proxied.yml) it references
+a companion squid proxy by setting the equivalent of
+
+    -e PROXY=proxy:3128

+Runs the Gremlin console from the Titan Graph Database's "all" distribution.
+
+# Basic Usage
+
+To start the Gremlin console with the default configuration files available:
+
+    docker run -it itzg/titan-gremlin
+
+In order to adjust or further define property files to use within Gremlin,
+attach a host directory to the container's `/conf` such as
+
+    docker run -it -v $(pwd)/conf:/conf itzg/titan-gremlin
+
+After running once your host directory will be populated with the distribution-default
+configuration files. Modify those or add to them and they will be available during
+the next time you (re)start your container.
+
+# Connecting to Cassandra and Elasticsearch Containers
+
+First start containers for Cassandra and Elasticsearch (pre-2.x),
+where the `--name` you choose can be arbitrary or left off to use a generated name.
+
+    docker run -d --name gremlin-cass itzg/cassandra
+    docker run -d --name gremlin-es itzg/elasticsearch:1.x
+
+Now start Gremlin with networking links to those containers with the aliases
+
+* `--link <container>:cass`
+* `--link <container>:es`
+
+such as
+
+    docker run -it --rm --link gremlin-cass:cass --link gremlin-es:es itzg/titan-gremlin
+
+and with that you can follow the
+[Graph of the Gods example](http://s3.thinkaurelius.com/docs/titan/current/getting-started.html), such as
+
+    gremlin> GraphOfTheGodsFactory.load(g)
+    gremlin> saturn = g.V.has('name','saturn').next()
+    ==>v[256]
+    gremlin> saturn.map()
+    ==>name=saturn
+    ==>age=10000
+    gremlin> saturn.in('father').in('father').name
+    ==>hercules
+
+# Running and Connecting with Docker Compose
+
+Create the following Compose content as the file `docker-compose.yml` and in
+that directory invoke `docker-compose run titan` to run the Gremlin shell
+with the supporting Elasticsearch and Cassandra containers.
+
+```
+titan:
+    image: itzg/titan-gremlin
+    links:
+        - cass
+        - es
