-        - Do you just have a question about something? If so, asking in the [Q&A Discussions](https://github.com/itzg/docker-minecraft-server/discussions/categories/q-a) or asking on [the Discord server](https://discord.gg/DXfKpjB) would be best.
-        - Is this bug happening after the `[init]` prefixed logs and after the log that says "Starting the Minecraft server"? If so, please report the bug with Mojang or the respective server provider.
-        - Are you seeing a performance problem? If so, that is typically outside the scope of the image setup mechanims. Ask a question as above or contact the respective server provider.

-## Adding a server type
-
-Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:
-
-1. Copy an existing "start-deploy*" script, such as [start-deployMohist](scripts/start-deployMohist) and rename it accordingly making sure to retain the "start-deploy" prefix
-2. Modify the type-specific behavior between the "start-utils" preamble and the hand-off to `start-setupWorld` at the end of the script 
-3. Develop and test the changes using the [iterative process described below](#iterative-script-development)
-4. Add a case-entry to the `case "${TYPE^^}"` in [start-configuration](scripts/start-configuration)
-5. Add a section to the [README](README.md). It is recommended to copy-modify an existing section to retain a similar wording and level of detail
-6. [Submit a pull request](https://github.com/itzg/docker-minecraft-server/pulls)
-
-## Iterative script development
-
-Individual scripts can be iteratively developed, debugged, and tested using the following procedure.
-
-First, build a baseline of the image to include the packages needed by existing or new scripts:
-
-```shell script
-docker build -t mc-dev .
-```
-
-Using the baseline image, an interactive container can be started to iteratively run the scripts to be developed. By attaching the current workspace directory, you can use the local editor of your choice to iteratively modify scripts while using the container to run them.
-
-```shell script
-docker run -it --rm -v ${PWD}:/scripts -e SCRIPTS=/scripts/ --entrypoint bash mc-dev
-```
-
-From within the container you can run individual scripts via the attached `/scripts/` path; however, be sure to set any environment variables expected by the scripts by either `export`ing them manually:
-
-```shell script
-export VANILLA_VERSION=1.12.2
-/scripts/start-magma
-```
-
-...or pre-pending script execution:
-
-```shell script
-VANILLA_VERSION=1.12.2 /scripts/start-magma
-```
-
-> NOTE: You may want to temporarily add an `exit` statement near the end of your script to isolate execution to just the script you're developing.
-
-## Using development copy of mc-image-helper
-
-In the cloned copy of [`mc-image-helper`](https://github.com/itzg/mc-image-helper), create an up-to-date snapshot build of the tgz distribution using:
-
-```shell
-./gradlew distTar
-```
-
-Assuming [http-server](https://www.npmjs.com/package/http-server) is installed globally, start a static web server using:
-
-```shell
-http-server ./build/distributions -p 0
-```
-
-Note the port that was selected by http-server and pass the build arguments, such as:
-
-```shell
---build-arg MC_HELPER_VERSION=1.8.1-SNAPSHOT \
---build-arg MC_HELPER_BASE_URL=http://host.docker.internal:8080
-```
-
-Now the image can be built like normal and it will install mc-image-helper from the locally built copy.
-
-## Multi-base-image variants
-
-Several base-image variants are maintained in order to offer choices in JDK provider and version. The variants are maintained in their respective branches:
-- openj9 
-- openj9-nightly
-- adopt11
-- adopt13
-- multiarch
-
-The [docker-versions-create.sh](docker-versions-create.sh) script is configured with the branches to maintain and is used to merge changes from the master branch into the mulit-base variant branches. The script also manages git tagging the master branch along with the merged branches. So a typical use of the script would be like:
-
-```shell script
-./docker-versions-create.sh -s -t 1.2.0
-```
-
-> Most often the major version will be bumped unless a bug or hotfix needs to be published in which case the patch version should be incremented.
-
-> The build and publishing of those branches and their tags is currently performed within Docker Hub.
-
-## multiarch support
-
-The [multiarch branch](https://github.com/itzg/docker-minecraft-server/tree/multiarch) supports running the image on amd64, arm64, and armv7 (aka RaspberryPi). Unlike the mainline branches, it is based on Ubuntu 18.04 since the openjdk package provided by Ubuntu includes full JIT support on all of the processor types.
-
-The multiarch images are built and published by [a Github action](https://github.com/itzg/docker-minecraft-server/actions?query=workflow%3A%22Build+and+publish+multiarch%22), which [is configured in that branch](https://github.com/itzg/docker-minecraft-server/blob/multiarch/.github/workflows/build-multiarch.yml).
-
-## Generating release notes
-
-The following git command can be used to provide the bulk of release notes content:
-
-```shell script
-git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="* %s" 1.1.0..1.2.0
-```
-## Tracking changes from master without content
-
-The following script uses the [ours](https://git-scm.com/docs/merge-strategies#Documentation/merge-strategies.txt-ours) merging strategy to track the history from master into the other branches without actually bringing the changes over. It is useful when a change is specific to master only, such as bumping the base Java version for the `latest` image tag.
-
-```shell
-branches=(
-  java8
-  java8-multiarch
-  java8-openj9
-  java11
-  java11-openj9
-  java16
-  java16-openj9
-  java17
-)
-
-for b in "${branches[@]}"; do
-  git checkout "$b"
-  git merge -s ours -m "Track latest from master" master
-  git push origin
-done

+## Using the persistent/shared workarea
+
+Since devbox containers are intended to be disposable, the image is configured 
+with a "volume" at `/shared`. 
+
+There are a couple of ways you can leverage that volume. Either attach it to
+a host-local directory:
+
+    docker run -it -v $(pwd)/workarea:/shared --rm itzg/devbox
+
+or run a "base" container and mounts the `/shared` from that onto any
+subsequent containers:
+
+    docker run --name devbox-base itzg/devbox touch /shared/READY
+    ...later...
+    docker run -it --volumes-from devbox-base --rm itzg/devbox
+
+**NOTE** I am using the `--rm` option so the devbox containers will be truly
+"burn after use".

+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.
+
+# 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                    es
+    docker run -d --name es1 --link es0 -e UNICAST_HOSTS=es0 es
+    docker run -d --name es2 --link es0 -e UNICAST_HOSTS=es0 es
+
+
+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
+    }
+
+# 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.
+* `GATEWAY` : only operates as a client node or a "smart router". These are the ones whose HTTP port 9200 will need to be exposed
+
+A [Docker Compose](https://docs.docker.com/compose/overview/) file will serve as a good example of these three node types:
+
+```
+version: '2'
+
+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
+```
+
+## 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
+
+## Auto transport/http discovery with 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_`.
+
+To resolve this, add
+
+    -e DISCOVER_TRANSPORT_IP=eth0
+
+replacing `eth0` with another interface within the container, if needed.
+
+The same can be done for publish/binding of the http module by adding:
+
+    -e DISCOVERY_HTTP_IP=eth2

+Provides a ready-to-use instance of [GitBlit](http://gitblit.com/).
+
+## 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.

+This container is pre-configured according to the 
+[GitHub Pages use of Jekyll](https://help.github.com/articles/using-jekyll-with-pages).
+
+It serves up the generated content on port 4000 and the site is generated from
+the container's `/site` volume. You can either bring your own site content or
+let it generate some VERY simple content along with the standard Jekyll directory
+layout.
+
+A typical way to run this:
+
+    docker run -it -p 4000:4000 -v $(pwd)/site:/site itzg/jekyll-github-pages
+
+where either it will load your content or initialize the content under

+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
+
+* `JENKINS_OPTS` - passed to the initial Java invocation of Jenkins

+Provides a ready-to-run [Kibana](http://www.elasticsearch.org/overview/kibana/) server that can
+easily hook into your [Elasticsearch containers](https://registry.hub.docker.com/u/itzg/elasticsearch/).
+
+## 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
+
+```
+udp {
+  port => 25826
+  codec => collectd { }
+  buffer_size => 1452
+}
+```
