What is Elasticsearch?

Elasticsearch is a highly scalable open-source full-text search and analytics engine. It allows you to store, search, and analyze big volumes of data quickly and in near real time

elastic.co/products/elasticsearch

TL;DR

$ docker run --name elasticsearch bitnami/elasticsearch:latest

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-elasticsearch/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

You can find the available configuration options in the Environment Variables section.

Why use Bitnami Images?

Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
With Bitnami images the latest bug fixes and features are available as soon as possible.
Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

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.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

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.

Supported tags and respective `Dockerfile` links

Get this image

The recommended way to get the Bitnami Elasticsearch Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/elasticsearch:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

$ docker pull bitnami/elasticsearch:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/elasticsearch:latest 'https://github.com/bitnami/bitnami-docker-elasticsearch.git#master:7/debian-10'

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.

$ 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 file present in this repository:

mariadb:
  ...
  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.

Connecting to other containers

Using Docker container networking, a 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

$ 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.

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

Step 3: Launch your application container

$ docker run -d --name myapp \
    --network app-tier \
    YOUR_APPLICATION_IMAGE

IMPORTANT:

Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image

In your application container, use the hostname elasticsearch-server to connect to the Elasticsearch server

Using Docker Compose

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.

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:

Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image

In your application container, use the hostname elasticsearch to connect to the Elasticsearch server

Launch the containers using:

$ docker-compose up -d

Configuration

Environment variables

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:

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

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

 $ 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

Available variables:

BITNAMI_DEBUG: Increase verbosity on initialization logs. Default false
ELASTICSEARCH_EXTRA_FLAGS: Extra command-line arguments for the elasticsearch daemon
ELASTICSEARCH_CLUSTER_NAME: The Elasticsearch Cluster Name. Default: elasticsearch-cluster
ELASTICSEARCH_CLUSTER_HOSTS: List of elasticsearch hosts to set the cluster. Available separators are ' ', ',' and ';'. No defaults.
ELASTICSEARCH_CLUSTER_MASTER_HOSTS: List of elasticsearch master-eligible hosts. Available separators are ' ', ',' and ';'. If no values are provided, it will have the same value than ELASTICSEARCH_CLUSTER_HOSTS.
ELASTICSEARCH_IS_DEDICATED_NODE: Elasticsearch node to behave as a 'dedicated node'. Default: no
ELASTICSEARCH_NODE_TYPE: Elasticsearch node type when behaving as a 'dedicated node'. Valid values: master, data, coordinating or ingest.
ELASTICSEARCH_NODE_NAME: Elasticsearch node name. No defaults.
ELASTICSEARCH_BIND_ADDRESS: Address/interface to bind by Elasticsearch. Default: 0.0.0.0
ELASTICSEARCH_PORT_NUMBER: Elasticsearch port. Default: 9200
ELASTICSEARCH_NODE_PORT_NUMBER: Elasticsearch Node to Node port. Default: 9300
ELASTICSEARCH_PLUGINS: Comma, semi-colon or space separated list of plugins to install at initialization. No defaults.
ELASTICSEARCH_KEYS: Comma, semi-colon or space separated list of key-value pairs (key=value) to store. No defaults.
ELASTICSEARCH_HEAP_SIZE: Memory used for the Xmx and Xms java heap values. Default: 1024m
ELASTICSEARCH_FS_SNAPSHOT_REPO_PATH: Elasticsearch file system snapshot repository path. No defaults.

Setting up a cluster

A cluster can easily be setup with the Bitnami Elasticsearch Docker Image using the following environment variables:

ELASTICSEARCH_CLUSTER_NAME: The Elasticsearch Cluster Name. Default: elasticsearch-cluster
ELASTICSEARCH_CLUSTER_HOSTS: List of elasticsearch hosts to set the cluster. Available separators are ' ', ',' and ';'. No defaults.
ELASTICSEARCH_CLIENT_NODE: Elasticsearch node to behave as a 'smart router' for Kibana app. Default: false
ELASTICSEARCH_NODE_NAME: Elasticsearch node name. No defaults.
ELASTICSEARCH_MINIMUM_MASTER_NODES: Minimum Elasticsearch master nodes for quorum. No defaults.

For larger cluster, you can setup 'dedicated nodes' using the following environment variables:

ELASTICSEARCH_IS_DEDICATED_NODE: Elasticsearch node to behave as a 'dedicated node'. Default: no
ELASTICSEARCH_NODE_TYPE: Elasticsearch node type when behaving as a 'dedicated node'. Valid values: master, data, coordinating or ingest.
ELASTICSEARCH_CLUSTER_MASTER_HOSTS: List of elasticsearch master-eligible hosts. Available separators are ' ', ',' and ';'. If no values are provided, it will have the same value than ELASTICSEARCH_CLUSTER_HOSTS.
ELASTICSEARCH_TOTAL_NODES: Number of master + data nodes, it's used to calculate gateway.expected_nodes and gateway.recover_after_nodes parameters. If not set, those parameters are calculated using ELASTICSEARCH_CLUSTER_HOSTS. No defaults.

Find more information about 'dedicated nodes' in the official documentation.

Step 1: Create a new network.

$ docker network create elasticsearch_network

Step 2: Create a first node.

$ 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 randon one.

Step 3: Create a second node

$ 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:

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:

$ 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 file present in this repository:

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 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.

$ 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 flowing command:

docker build --build-arg ELASTICSEARCH_PLUGINS=<plugin1,plugin2,...> https://github.com/bitnami/bitnami-docker-elasticsearch.git#:7/debian-10 -t my-elasticsearch

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.

Logging

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

$ docker logs elasticsearch

or using Docker Compose:

$ docker-compose logs elasticsearch

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

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

$ 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

$ docker stop elasticsearch

or using Docker Compose:

$ docker-compose stop elasticsearch

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

$ 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

$ docker rm -v elasticsearch

or using Docker Compose:

$ docker-compose rm -v elasticsearch

Step 4: Run the new image

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

$ docker run --name elasticsearch bitnami/elasticsearch:latest

or using Docker Compose:

$ 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 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 are not supported (only 1001 UID is allowed).
This is temporary solution while Elasticsearch maintainers address an issue with ownership/permissions when installing plugins. Issue reported at: https://github.com/bitnami/bitnami-docker-elasticsearch/issues/50

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:

$ 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.
