+[![Build Status](https://api.travis-ci.org/deviantony/docker-elk.svg?branch=master)](https://travis-ci.org/deviantony/docker-elk)
+
+Run the latest version of the [Elastic stack][elk-stack] with Docker and Docker Compose.
+
+It gives you the ability to analyze any data set by using the searching/aggregation capabilities of Elasticsearch and
+the visualization power of Kibana.
+
+> :information_source: The Docker images backing this stack include [Stack Features][stack-features] (formerly X-Pack)
+with [paid features][paid-features] enabled by default (see [How to disable paid
+features](#how-to-disable-paid-features) to disable them). The [trial license][trial-license] is valid for 30 days.
+
+Based on the official Docker images from Elastic:
+
+* [Elasticsearch](https://github.com/elastic/elasticsearch/tree/master/distribution/docker)
+* [Logstash](https://github.com/elastic/logstash/tree/master/docker)
+* [Kibana](https://github.com/elastic/kibana/tree/master/src/dev/build/tasks/os_packages/docker_generator)
+
+Other available stack variants:
+
+* [`searchguard`](https://github.com/deviantony/docker-elk/tree/searchguard): Search Guard support

+## Requirements
+
+### Host setup
+
+* [Docker Engine](https://docs.docker.com/install/) version **17.05+**
+* [Docker Compose](https://docs.docker.com/compose/install/) version **1.12.0+**
+* 1.5 GB of RAM
+
+By default, the stack exposes the following ports:
+* 5000: Logstash TCP input
+* 9200: Elasticsearch HTTP
+* 9300: Elasticsearch TCP transport
+* 5601: Kibana
+
+> :information_source: Elasticsearch's [bootstrap checks][booststap-checks] were purposely disabled to facilitate the
+> setup of the Elastic stack in development environments. For production setups, we recommend users to set up their host
+> according to the instructions from the Elasticsearch documentation: [Important System Configuration][es-sys-config].
+
+### SELinux
+
+On distributions which have SELinux enabled out-of-the-box you will need to either re-context the files or set SELinux
+into Permissive mode in order for docker-elk to start properly. For example on Redhat and CentOS, the following will
+apply the proper context:
+
+```console
+$ chcon -R system_u:object_r:admin_home_t:s0 docker-elk/
+```
+
+### Docker for Desktop
+
+#### Windows
+
+Ensure the [Shared Drives][win-shareddrives] feature is enabled for the `C:` drive.
+
+#### macOS
+
+The default Docker for Mac configuration allows mounting files from `/Users/`, `/Volumes/`, `/private/`, and `/tmp`
+exclusively. Make sure the repository is cloned in one of those locations or follow the instructions from the
+[documentation][mac-mounts] to add more locations.
+
+## Usage
+
+### Bringing up the stack
+
+Clone this repository, then start the stack using Docker Compose:
+
+```console
+$ docker-compose up
+```
+
+You can also run all services in the background (detached mode) by adding the `-d` flag to the above command.
+
+> :information_source: You must run `docker-compose build` first whenever you switch branch or update a base image.
+
+If you are starting the stack for the very first time, please read the section below attentively.
+
+### Cleanup
+
+Elasticsearch data is persisted inside a volume by default.
+
+In order to entirely shutdown the stack and remove all persisted data, use the following Docker Compose command:
+
+```console
+$ docker-compose down -v
+```
+
+## Initial setup
+
+### Setting up user authentication
+
+> :information_source: Refer to [How to disable paid features](#how-to-disable-paid-features) to disable authentication.
+
+The stack is pre-configured with the following **privileged** bootstrap user:
+
+* user: *elastic*
+* password: *changeme*
+
+Although all stack components work out-of-the-box with this user, we strongly recommend using the unprivileged [built-in
+users][builtin-users] instead for increased security. Passwords for these users must be initialized:
+
+```console
+$ docker-compose exec -T elasticsearch bin/elasticsearch-setup-passwords auto --batch
+```
+
+Passwords for all 6 built-in users will be randomly generated. Take note of them and replace the `elastic` username with
+`kibana` and `logstash_system` inside the Kibana and Logstash configuration files respectively. See the
+[Configuration](#configuration) section below.
+
+> :information_source: Do not use the `logstash_system` user inside the Logstash *pipeline* file, it does not have
+> sufficient permissions to create indices. Follow the instructions at [Configuring Security in Logstash][ls-security]
+> to create a user with suitable roles.
+
+Restart Kibana and Logstash to apply the passwords you just wrote to the configuration files.
+
+```console
+$ docker-compose restart kibana logstash
+```
+
+> :information_source: Learn more about the security of the Elastic stack at [Tutorial: Getting started with
+> security][sec-tutorial].
+
+### Injecting data
+
+Give Kibana about a minute to initialize, then access the Kibana web UI by hitting
+[http://localhost:5601](http://localhost:5601) with a web browser and use the following default credentials to log in:
+
+* user: *elastic*
+* password: *\<your generated elastic password>*
+
+Now that the stack is running, you can go ahead and inject some log entries. The shipped Logstash configuration allows
+you to send content via TCP:
+
+```console
+$ nc localhost 5000 < /path/to/logfile.log
+```
+
+You can also load the sample data provided by your Kibana installation.
+
+### Default Kibana index pattern creation
+
+When Kibana launches for the first time, it is not configured with any index pattern.
+
+#### Via the Kibana web UI
+
+> :information_source: You need to inject data into Logstash before being able to configure a Logstash index pattern via
+the Kibana web UI. Then all you have to do is hit the *Create* button.
+
+Refer to [Connect Kibana with Elasticsearch][connect-kibana] for detailed instructions about the index pattern
+configuration.
+
+#### On the command line
+
+Create an index pattern via the Kibana API:
+
+```console
+$ curl -XPOST -D- 'http://localhost:5601/api/saved_objects/index-pattern' \
+    -H 'Content-Type: application/json' \
+    -H 'kbn-version: 7.4.1' \
+    -u elastic:<your generated elastic password> \
+    -d '{"attributes":{"title":"logstash-*","timeFieldName":"@timestamp"}}'
+```
+
+The created pattern will automatically be marked as the default index pattern as soon as the Kibana UI is opened for the first time.
+
+## Configuration
+
+> :information_source: Configuration is not dynamically reloaded, you will need to restart individual components after
+any configuration change.
+
+### How to configure Elasticsearch
+
+The Elasticsearch configuration is stored in [`elasticsearch/config/elasticsearch.yml`][config-es].
+
+You can also specify the options you want to override by setting environment variables inside the Compose file:
+
+```yml
+elasticsearch:
+
+  environment:
+    network.host: _non_loopback_
+    cluster.name: my-cluster
+```
+
+Please refer to the following documentation page for more details about how to configure Elasticsearch inside Docker
+containers: [Install Elasticsearch with Docker][es-docker].
+
+### How to configure Kibana
+
+The Kibana default configuration is stored in [`kibana/config/kibana.yml`][config-kbn].
+
+It is also possible to map the entire `config` directory instead of a single file.
+
+Please refer to the following documentation page for more details about how to configure Kibana inside Docker
+containers: [Running Kibana on Docker][kbn-docker].
+
+### How to configure Logstash
+
+The Logstash configuration is stored in [`logstash/config/logstash.yml`][config-ls].
+
+It is also possible to map the entire `config` directory instead of a single file, however you must be aware that
+Logstash will be expecting a [`log4j2.properties`][log4j-props] file for its own logging.
+
+Please refer to the following documentation page for more details about how to configure Logstash inside Docker
+containers: [Configuring Logstash for Docker][ls-docker].
+
+### How to disable paid features
+
+Switch the value of Elasticsearch's `xpack.license.self_generated.type` option from `trial` to `basic` (see [License
+settings][trial-license]).
+
+### How to scale out the Elasticsearch cluster
+
+Follow the instructions from the Wiki: [Scaling out Elasticsearch](https://github.com/deviantony/docker-elk/wiki/Elasticsearch-cluster)
+
+## Extensibility
+
+### How to add plugins
+
+To add plugins to any ELK component you have to:
+
+1. Add a `RUN` statement to the corresponding `Dockerfile` (eg. `RUN logstash-plugin install logstash-filter-json`)
+2. Add the associated plugin code configuration to the service configuration (eg. Logstash input/output)
+3. Rebuild the images using the `docker-compose build` command
+
+### How to enable the provided extensions
+
+A few extensions are available inside the [`extensions`](extensions) directory. These extensions provide features which
+are not part of the standard Elastic stack, but can be used to enrich it with extra integrations.
+
+The documentation for these extensions is provided inside each individual subdirectory, on a per-extension basis. Some
+of them require manual changes to the default ELK configuration.
+
+## JVM tuning
+
+### How to specify the amount of memory used by a service
+
+By default, both Elasticsearch and Logstash start with [1/4 of the total host
+memory](https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/parallel.html#default_heap_size) allocated to
+the JVM Heap Size.
+
+The startup scripts for Elasticsearch and Logstash can append extra JVM options from the value of an environment
+variable, allowing the user to adjust the amount of memory that can be used by each component:
+
+| Service       | Environment variable |
+|---------------|----------------------|
+| Elasticsearch | ES_JAVA_OPTS         |
+| Logstash      | LS_JAVA_OPTS         |
+
+To accomodate environments where memory is scarce (Docker for Mac has only 2 GB available by default), the Heap Size
+allocation is capped by default to 256MB per service in the `docker-compose.yml` file. If you want to override the
+default JVM configuration, edit the matching environment variable(s) in the `docker-compose.yml` file.
+
+For example, to increase the maximum JVM Heap Size for Logstash:
+
+```yml
+logstash:
+
+  environment:
+    LS_JAVA_OPTS: -Xmx1g -Xms1g
+```
+
+### How to enable a remote JMX connection to a service
+
+As for the Java Heap memory (see above), you can specify JVM options to enable JMX and map the JMX port on the Docker
+host.
+
+Update the `{ES,LS}_JAVA_OPTS` environment variable with the following content (I've mapped the JMX service on the port
+18080, you can change that). Do not forget to update the `-Djava.rmi.server.hostname` option with the IP address of your
+Docker host (replace **DOCKER_HOST_IP**):
+
+```yml
+logstash:
+
+  environment:
+    LS_JAVA_OPTS: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=18080 -Dcom.sun.management.jmxremote.rmi.port=18080 -Djava.rmi.server.hostname=DOCKER_HOST_IP -Dcom.sun.management.jmxremote.local.only=false
+```
+
+## Going further
+
+### Using a newer stack version
+
+To use a different Elastic Stack version than the one currently available in the repository, simply change the version
+number inside the `.env` file, and rebuild the stack with:
+
+```console
+$ docker-compose build
+$ docker-compose up
+```
+
+> :information_source: Always pay attention to the [upgrade instructions][upgrade] for each individual component before
+performing a stack upgrade.
+
+### Plugins and integrations
+
+See the following Wiki pages:
+
+* [External applications](https://github.com/deviantony/docker-elk/wiki/External-applications)
+* [Popular integrations](https://github.com/deviantony/docker-elk/wiki/Popular-integrations)
+
+### Swarm mode
+
+Experimental support for Docker [Swarm mode][swarm-mode] is provided in the form of a `docker-stack.yml` file, which can
+be deployed in an existing Swarm cluster using the following command:
+
+```console
+$ docker stack deploy -c docker-stack.yml elk
+```
+
+If all components get deployed without any error, the following command will show 3 running services:
+
+```console
+$ docker stack services elk
+```
+
+> :information_source: To scale Elasticsearch in Swarm mode, configure *zen* to use the DNS name `tasks.elasticsearch`
+instead of `elasticsearch`.

docker-elk-master/extensions/apm-server/README.md

+# APM Server extension
+
+Adds a container for Elasticsearch APM server. Forwards caught errors and traces to Elasticsearch to enable their
+visualisation in Kibana.
+
+## Usage
+
+If you want to include the APM server, run Docker Compose from the root of the repository with an additional command
+line argument referencing the `apm-server-compose.yml` file:
+
+```console
+$ docker-compose -f docker-compose.yml -f extensions/apm-server/apm-server-compose.yml up
+```
+
+## Connecting an agent to APM-Server
+
+The most basic configuration to send traces to APM server is to specify the `SERVICE_NAME` and `SERVICE_URL`. Here is an
+example Python FLASK configuration:
+
+```python
+import elasticapm
+from elasticapm.contrib.flask import ElasticAPM
+
+from flask import Flask
+
+app = Flask(__name__)
+app.config['ELASTIC_APM'] = {
+    # Set required service name. Allowed characters:
+    # a-z, A-Z, 0-9, -, _, and space
+    'SERVICE_NAME': 'PYTHON_FLASK_TEST_APP',
+
+    # Set custom APM Server URL (default: http://localhost:8200)
+    'SERVER_URL': 'http://apm-server:8200',
+
+    'DEBUG': True,
+}
+```
+
+More configuration settings can be found under the **Configuration** section for each language:
+https://www.elastic.co/guide/en/apm/agent/index.html
+
+## Checking connectivity and importing default APM dashboards
+
+From the Kibana Dashboard:
+
+1. `Add APM` button under _Add Data to Kibana_ section
+2. Ignore all the install instructions and press `Check APM Server status` button.
+3. Press `Check agent status`
+4. Press `Load Kibana objects` to get the default dashboards
+5. Lastly press the `APM dashboard` to the bottom right.

+# Logspout extension
+
+Logspout collects all Docker logs using the Docker logs API, and forwards them to Logstash without any additional
+configuration.
+
+## Usage
+
+If you want to include the Logspout extension, run Docker Compose from the root of the repository with an additional
+command line argument referencing the `logspout-compose.yml` file:
+
+```bash
+$ docker-compose -f docker-compose.yml -f extensions/logspout/logspout-compose.yml up
+```
+
+In your Logstash pipeline configuration, enable the `udp` input and set the input codec to `json`:
+
+```
+input {
+  udp {
+    port  => 5000
+    codec => json
+  }
+}
+```
