# Bitnami Elasticsearch Stack

## What is Elasticsearch?

> Elasticsearch is a distributed search and analytics engine. It is used for web search, log monitoring, and real-time analytics. Ideal for Big Data applications.

[Overview of Elasticsearch](https://www.elastic.co/products/elasticsearch)
Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

## TL;DR

```console
docker run --name elasticsearch bitnami/elasticsearch:latest
```

You can find the available configuration options in the [Environment Variables](#environment-variables) section.

## Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise [OS Photon Linux](https://vmware.github.io/photon/). Why choose BSI images?

- Hardened secure images of popular open source software with Near-Zero Vulnerabilities
- Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
- Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
- Software supply chain provenance attestation through in-toto
- First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in [our public catalog here](https://app-catalog.vmware.com/bitnami/apps). Note: Some data is only available with [commercial subscriptions to BSI](https://bitnami.com/).

## How to deploy Elasticsearch in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the [Bitnami Elasticsearch Chart GitHub repository](https://github.com/bitnami/charts/tree/master/bitnami/elasticsearch).

## Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers [in our docs](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-work-with-non-root-containers-index.html).

## Supported tags and respective `Dockerfile` links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html).

## Get this image

The recommended way to get the Bitnami Elasticsearch Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/elasticsearch).

```console
docker pull bitnami/elasticsearch:latest
```

To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/elasticsearch/tags/) in the Docker Hub Registry.

```console
docker pull bitnami/elasticsearch:[TAG]
```

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.

```console
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .
```

## Persisting your application

If you remove the container all your data will be lost, and the next time you run the image the application will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the `/bitnami` path. If the mounted directory is empty, it will be initialized on the first run.

```console
docker run \
    -v /path/to/elasticsearch-data-persistence:/bitnami/elasticsearch/data \
    bitnami/elasticsearch:latest
```

or by making a minor change to the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/elasticsearch/docker-compose.yml) file present in this repository:

```yaml
elasticsearch:
  ...
  volumes:
    - /path/to/elasticsearch-data-persistence:/bitnami/elasticsearch/data
  ...
```

> NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID `1001`.

It is also possible to use multiple volumes for data persistence by using the `ELASTICSEARCH_DATA_DIR_LIST` environment variable:

```yaml
elasticsearch:
  ...
  volumes:
    - /path/to/elasticsearch-data-persistence-1:/elasticsearch/data-1
    - /path/to/elasticsearch-data-persistence-2:/elasticsearch/data-2
  environment:
    - ELASTICSEARCH_DATA_DIR_LIST=/elasticsearch/data-1,/elasticsearch/data-2
  ...
```

## Connecting to other containers

Using [Docker container networking](https://docs.docker.com/engine/userguide/networking/), an Elasticsearch server running inside a container can easily be accessed by your application containers.

Containers attached to the same network can communicate with each other using the container name as the hostname.

### Using the Command Line

#### Step 1: Create a network

```console
docker network create app-tier --driver bridge
```

#### Step 2: Launch the Elasticsearch server instance

Use the `--network app-tier` argument to the `docker run` command to attach the Elasticsearch container to the `app-tier` network.

```console
docker run -d --name elasticsearch-server \
    --network app-tier \
    bitnami/elasticsearch:latest
```

#### Step 3: Launch your application container

```console
docker run -d --name myapp \
    --network app-tier \
    YOUR_APPLICATION_IMAGE
```

> **IMPORTANT**:
>
> 1. Please update the **YOUR_APPLICATION_IMAGE_** placeholder in the above snippet with your application image
> 2. In your application container, use the hostname `elasticsearch-server` to connect to the Elasticsearch server

### Using a Docker Compose file

When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new `bridge` network named `app-tier`. In this example we assume that you want to connect to the Elasticsearch server from your own custom application image which is identified in the following snippet by the service name `myapp`.

```yaml
version: '2'

networks:
  app-tier:
    driver: bridge

services:
  elasticsearch:
    image: bitnami/elasticsearch:latest
    networks:
      - app-tier
  myapp:
    image: YOUR_APPLICATION_IMAGE
    networks:
      - app-tier
```

> **IMPORTANT**:
>
> 1. Please update the **YOUR_APPLICATION_IMAGE_** placeholder in the above snippet with your application image
> 2. In your application container, use the hostname `elasticsearch` to connect to the Elasticsearch server

Launch the containers using:

```console
docker-compose up -d
```

When you start the elasticsearch image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the `docker run` command line. If you want to add a new environment variable:

- For Docker Compose, add the variable name and value under the application section:

```yaml
elasticsearch:
  ...
  environment:
    - ELASTICSEARCH_PORT_NUMBER=9201
  ...
```

- For manual execution add a `-e` option with each variable and value:

```console
 $ docker run -d --name elasticsearch \
    -p 9201:9201 --network=elasticsearch_network \
    -e ELASTICSEARCH_PORT_NUMBER=9201 \
    -v /path/to/elasticsearch-data-persistence:/bitnami/elasticsearch/data \
    bitnami/elasticsearch
```

#### Step 1: Create a new network

```console
docker network create elasticsearch_network
```

#### Step 2: Create the first node

```console
docker run --name elasticsearch-node1 \
  --net=elasticsearch_network \
  -p 9200:9200 \
  -e ELASTICSEARCH_CLUSTER_NAME=elasticsearch-cluster \
  -e ELASTICSEARCH_CLUSTER_HOSTS=elasticsearch-node1,elasticsearch-node2 \
  -e ELASTICSEARCH_NODE_NAME=elastic-node1 \
  bitnami/elasticsearch:latest
```

In the above command the container is added to a cluster named `elasticsearch-cluster` using the `ELASTICSEARCH_CLUSTER_NAME`. The `ELASTICSEARCH_CLUSTER_HOSTS` parameter set the name of the nodes that set the cluster so we will need to launch other container for the second node. Finally the `ELASTICSEARCH_NODE_NAME` parameter allows to indicate a known name for the node, otherwise elasticsearch will generate a random one.

#### Step 3: Create a second node

```console
docker run --name elasticsearch-node2 \
  --link elasticsearch-node1:elasticsearch-node1 \
  --net=elasticsearch_network \
  -e ELASTICSEARCH_CLUSTER_NAME=elasticsearch-cluster \
  -e ELASTICSEARCH_CLUSTER_HOSTS=elasticsearch-node1,elasticsearch-node2 \
  -e ELASTICSEARCH_NODE_NAME=elastic-node2 \
  bitnami/elasticsearch:latest
```

In the above command a new elasticsearch node is being added to the elasticsearch cluster indicated by `ELASTICSEARCH_CLUSTER_NAME`.

You now have a two node Elasticsearch cluster up and running which can be scaled by adding/removing nodes.

With Docker Compose the cluster configuration can be setup using:

```yaml
version: '2'
services:
  elasticsearch-node1:
    image: bitnami/elasticsearch:latest
    environment:
      - ELASTICSEARCH_CLUSTER_NAME=elasticsearch-cluster
      - ELASTICSEARCH_CLUSTER_HOSTS=elasticsearch-node1,elasticsearch-node2
      - ELASTICSEARCH_NODE_NAME=elastic-node1

  elasticsearch-node2:
    image: bitnami/elasticsearch:latest
    environment:
      - ELASTICSEARCH_CLUSTER_NAME=elasticsearch-cluster
      - ELASTICSEARCH_CLUSTER_HOSTS=elasticsearch-node1,elasticsearch-node2
      - ELASTICSEARCH_NODE_NAME=elastic-node2
```

### Configuration file

In order to use a custom configuration file instead of the default one provided out of the box, you can create a file named `elasticsearch.yml` and mount it at `/opt/bitnami/elasticsearch/config/elasticsearch.yml` to overwrite the default configuration:

```console
docker run -d --name elasticsearch \
    -p 9201:9201 \
    -v /path/to/elasticsearch.yml:/opt/bitnami/elasticsearch/config/elasticsearch.yml \
    -v /path/to/elasticsearch-data-persistence:/bitnami/elasticsearch/data \
    bitnami/elasticsearch:latest
```

or by changing the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/elasticsearch/docker-compose.yml) file present in this repository:

```yaml
elasticsearch:
  ...
  volumes:
    - /path/to/elasticsearch.yml:/opt/bitnami/elasticsearch/config/elasticsearch.yml
    - /path/to/elasticsearch-data-persistence:/bitnami/elasticsearch/data
  ...
```

Please, note that the whole configuration file will be replaced by the provided, default one; ensure that the syntax and fields you provide are properly set and exhaustive.

If you would rather extend than replace the default configuration with your settings, mount your custom configuration file at `/opt/bitnami/elasticsearch/config/my_elasticsearch.yml`.

### Plugins

The Bitnami Elasticsearch Docker image comes with the [S3 Repository plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/repository-s3.html) installed by default.

You can add extra plugins by setting the `ELASTICSEARCH_PLUGINS` environment variable. To specify multiple plugins, separate them by spaces, commas or semicolons. When the container is initialized it will install all of the specified plugins before starting Elasticsearch.

```console
docker run -d --name elasticsearch \
    -e ELASTICSEARCH_PLUGINS=analysis-icu \
    bitnami/elasticsearch:latest
```

The Bitnami Elasticsearch Docker image will also install plugin `.zip` files mounted at the `/bitnami/elasticsearch/plugins` directory inside the container, making it possible to install them from disk without requiring Internet access.

#### Adding plugins at build time (persisting plugins)

The Bitnami Elasticsearch image provides a way to create your custom image installing plugins on build time. This is the preferred way to persist plugins when using ElasticSearch, as they will not be installed every time the container is started but just once at build time.

To create your own image providing plugins execute the following command. Remember to replace the `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.

```console
git clone https://github.com/bitnami/containers.git
cd bitnami/elasticsearch/VERSION/OPERATING-SYSTEM
docker build --build-arg ELASTICSEARCH_PLUGINS=<plugin1,plugin2,...> -t bitnami/elasticsearch:latest .
```

The command above will build the image providing this GitHub repository as build context, and will pass the list of plugins to install to the build logic.

### Initializing a new instance

When the container is executed for the first time, it will execute the files with extension `.sh` located at `/docker-entrypoint-initdb.d`.

In order to have your custom files inside the Docker image, you can mount them as a volume.

### FIPS configuration in Bitnami Secure Images

The Bitnami Elasticsearch Docker image from the [Bitnami Secure Images](https://go-vmware.broadcom.com/contact-us) catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

- `OPENSSL_FIPS`: whether OpenSSL runs in FIPS mode or not. `yes` (default), `no`.

## Logging

The Bitnami Elasticsearch Docker image sends the container logs to the `stdout`. To view the logs:

```console
docker logs elasticsearch
```

or using Docker Compose:

```console
docker-compose logs elasticsearch
```

You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver.

Additionally, in case you'd like to modify Elasticsearch logging configuration, it can be done by overwriting the file `/opt/bitnami/elasticsearch/config/log4j2.properties`.
The syntax of this file can be found in Elasticsearch [logging documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/logging.html).

## Maintenance

### Upgrade this image

Bitnami provides up-to-date versions of Elasticsearch, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.

#### Step 1: Get the updated image

```console
docker pull bitnami/elasticsearch:latest
```

or if you're using Docker Compose, update the value of the image property to
`bitnami/elasticsearch:latest`.

#### Step 2: Stop and backup the currently running container

Stop the currently running container using the command

```console
docker stop elasticsearch
```

or using Docker Compose:

```console
docker-compose stop elasticsearch
```

Next, take a snapshot of the persistent volume `/path/to/elasticsearch-data-persistence` using:

```console
rsync -a /path/to/elasticsearch-data-persistence /path/to/elasticsearch-data-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
```

You can use this snapshot to restore the application state should the upgrade fail.

#### Step 3: Remove the currently running container

```console
docker rm -v elasticsearch
```

or using Docker Compose:

```console
docker-compose rm -v elasticsearch
```

#### Step 4: Run the new image

Re-create your container from the new image, restoring your backup if necessary.

```console
docker run --name elasticsearch bitnami/elasticsearch:latest
```

or using Docker Compose:

```console
docker-compose up elasticsearch
```

## Notable Changes

### 7.12.0-debian-10-r0

- Elasticsearch 7.12.0 version or later are licensed under the Elastic License that is not currently accepted as an Open Source license by the Open Source Initiative (OSI).
- Elasticsearch 7.12.0 version or later are including x-pack plugin installed by default. Follow the official documentation to use it.

### 6.8.5-debian-9-r0, 6.8.5-ol-7-r1, 7.4.2-debian-9-r10, 7.4.2-ol-7-r27

- Arbitrary user ID(s) when running the container with a non-privileged user is not supported (only `1001` UID is allowed).
- This is temporary solution while Elasticsearch maintainers address an issue with ownership/permissions when installing plugins.

### 6.8.2-debian-9-r36, 6.8.2-ol-7-r36, 7.3.1-debian-9-r8, 7.3.1-ol-7-r13

- Updated OpenJDK to version 11

### 6.6.1-debian-9-r12, 6.6.1-ol-7-r13, 6.6.1-rhel-7-r13, 5.6.15-debian-9-r12 and 5.6.15-ol-7-r13

- Deprecate the use of `elasticsearch_custom.yml` in favor of replacing the whole `elasticsearch.yml` file.

### 6.4.0-debian-9-r19, 6.4.0-ol-7-r18, 5.6.4-debian-9-r54, and 5.6.4-ol-7-r60

- Decrease the size of the container. It is not necessary Node.js anymore. Elasticsearch configuration moved to bash scripts in the `rootfs/` folder.
- The recommended mount point to persist data changes to `/bitnami/elasticsearch/data`.
- The Elasticsearch configuration files are not persisted in a volume anymore. Now, they can be found at `/opt/bitnami/elasticsearch/config`.
- Elasticsearch `plugins` and `modules` are not persisted anymore. It's necessary to indicate what plugins to install using the env. variable `ELASTICSEARCH_PLUGINS`
- Backwards compatibility is not guaranteed when data is persisted using docker-compose. You can use the workaround below to overcome it:

```console
$ docker-compose down
# Change the mount point
sed -i -e 's#elasticsearch_data:/bitnami#elasticsearch_data:/bitnami/elasticsearch/data#g' docker-compose.yml
# Pull the latest bitnami/elasticsearch image
$ docker pull bitnami/elasticsearch:latest
$ docker-compose up -d
```

### 6.2.3-r7 & 5.6.4-r18

- The Elasticsearch container has been migrated to a non-root user approach. Previously the container ran as the `root` user and the Elasticsearch daemon was started as the `elasticsearch` user. From now on, both the container and the Elasticsearch daemon run as user `1001`. As a consequence, the data directory must be writable by that user. You can revert this behavior by changing `USER 1001` to `USER root` in the Dockerfile.

### 6.2.3-r2 & 5.6.4-r6

- Elasticsearch container can be configured as a dedicated node with 4 different types: *master*, *data*, *coordinating* or *ingest*.
  Previously it was only achievable by using a custom `elasticsearch_custom.yml` file. From now on, you can use the environment variables `ELASTICSEARCH_IS_DEDICATED_NODE` & `ELASTICSEARCH_NODE_TYPE` to configure it.
