////
|
||||
|
||||
To try out Elasticsearch on your own machine, we recommend using Docker
|
||||
and running both Elasticsearch and Kibana.
|
||||
Docker images are available from the https://www.docker.elastic.co[Elastic Docker registry].
|
||||
[WARNING]
|
||||
====
|
||||
DO NOT USE THESE INSTRUCTIONS FOR PRODUCTION DEPLOYMENTS.
|
||||
|
||||
NOTE: Starting in Elasticsearch 8.0, security is enabled by default.
|
||||
The first time you start Elasticsearch, TLS encryption is configured automatically,
|
||||
a password is generated for the `elastic` user,
|
||||
and a Kibana enrollment token is created so you can connect Kibana to your secured cluster.
|
||||
This setup is intended for local development and testing only.
|
||||
====
|
||||
|
||||
For other installation options, see the
|
||||
https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html[Elasticsearch installation documentation].
|
||||
The following commands help you very quickly spin up a single-node Elasticsearch cluster, together with Kibana in Docker.
|
||||
Use this setup for local development or testing.
|
||||
|
||||
**Start Elasticsearch**
|
||||
==== Prerequisites
|
||||
|
||||
. Install and start https://www.docker.com/products/docker-desktop[Docker
|
||||
Desktop]. Go to **Preferences > Resources > Advanced** and set Memory to at least 4GB.
|
||||
If you don't have Docker installed, https://www.docker.com/products/docker-desktop[download and install Docker Desktop] for your operating system.
|
||||
|
||||
. Start an Elasticsearch container:
|
||||
+
|
||||
==== Set environment variables
|
||||
|
||||
Configure the following environment variables.
|
||||
|
||||
[source,sh]
|
||||
----
|
||||
docker network create elastic
|
||||
docker pull docker.elastic.co/elasticsearch/elasticsearch:{version} <1>
|
||||
docker run --name elasticsearch --net elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -t docker.elastic.co/elasticsearch/elasticsearch:{version}
|
||||
export ELASTIC_PASSWORD="<ES_PASSWORD>" # password for "elastic" username
|
||||
export KIBANA_PASSWORD="<KIB_PASSWORD>" # Used internally by Kibana, must be at least 6 characters long
|
||||
----
|
||||
<1> Replace {version} with the version of Elasticsearch you want to run.
|
||||
+
|
||||
When you start Elasticsearch for the first time, the generated `elastic` user password and
|
||||
Kibana enrollment token are output to the terminal.
|
||||
+
|
||||
NOTE: You might need to scroll back a bit in the terminal to view the password
|
||||
and enrollment token.
|
||||
|
||||
. Copy the generated password and enrollment token and save them in a secure
|
||||
location. These values are shown only when you start Elasticsearch for the first time.
|
||||
You'll use these to enroll Kibana with your Elasticsearch cluster and log in.
|
||||
==== Create a Docker network
|
||||
|
||||
**Start Kibana**
|
||||
To run both Elasticsearch and Kibana, you'll need to create a Docker network:
|
||||
|
||||
Kibana enables you to easily send requests to Elasticsearch and analyze, visualize, and manage data interactively.
|
||||
|
||||
. In a new terminal session, start Kibana and connect it to your Elasticsearch container:
|
||||
+
|
||||
[source,sh]
|
||||
----
|
||||
docker pull docker.elastic.co/kibana/kibana:{version} <1>
|
||||
docker run --name kibana --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:{version}
|
||||
docker network create elastic-net
|
||||
----
|
||||
<1> Replace {version} with the version of Kibana you want to run.
|
||||
+
|
||||
When you start Kibana, a unique URL is output to your terminal.
|
||||
|
||||
. To access Kibana, open the generated URL in your browser.
|
||||
==== Run Elasticsearch
|
||||
|
||||
.. Paste the enrollment token that you copied when starting
|
||||
Elasticsearch and click the button to connect your Kibana instance with Elasticsearch.
|
||||
Start the Elasticsearch container with the following command:
|
||||
|
||||
.. Log in to Kibana as the `elastic` user with the password that was generated
|
||||
when you started Elasticsearch.
|
||||
[source,sh]
|
||||
----
|
||||
docker run -p 127.0.0.1:9200:9200 -d --name elasticsearch --network elastic-net \
|
||||
-e ELASTIC_PASSWORD=$ELASTIC_PASSWORD \
|
||||
-e "discovery.type=single-node" \
|
||||
-e "xpack.security.http.ssl.enabled=false" \
|
||||
-e "xpack.license.self_generated.type=trial" \
|
||||
docker.elastic.co/elasticsearch/elasticsearch:{version}
|
||||
----
|
||||
|
||||
**Send requests to Elasticsearch**
|
||||
==== Run Kibana (optional)
|
||||
|
||||
To run Kibana, you must first set the `kibana_system` password in the Elasticsearch container.
|
||||
|
||||
[source,sh]
|
||||
----
|
||||
# configure the Kibana password in the ES container
|
||||
curl -u elastic:$ELASTIC_PASSWORD \
|
||||
-X POST \
|
||||
http://localhost:9200/_security/user/kibana_system/_password \
|
||||
-d '{"password":"'"$KIBANA_PASSWORD"'"}' \
|
||||
-H 'Content-Type: application/json'
|
||||
----
|
||||
// NOTCONSOLE
|
||||
|
||||
Start the Kibana container with the following command:
|
||||
|
||||
[source,sh]
|
||||
----
|
||||
docker run -p 127.0.0.1:5601:5601 -d --name kibana --network elastic-net \
|
||||
-e ELASTICSEARCH_URL=http://elasticsearch:9200 \
|
||||
-e ELASTICSEARCH_HOSTS=http://elasticsearch:9200 \
|
||||
-e ELASTICSEARCH_USERNAME=kibana_system \
|
||||
-e ELASTICSEARCH_PASSWORD=$KIBANA_PASSWORD \
|
||||
-e "xpack.security.enabled=false" \
|
||||
-e "xpack.license.self_generated.type=trial" \
|
||||
docker.elastic.co/kibana/kibana:{version}
|
||||
----
|
||||
|
||||
.Trial license
|
||||
[%collapsible]
|
||||
====
|
||||
The service is started with a trial license. The trial license enables all features of Elasticsearch for a trial period of 30 days. After the trial period expires, the license is downgraded to a basic license, which is free forever. If you prefer to skip the trial and use the basic license, set the value of the `xpack.license.self_generated.type` variable to basic instead. For a detailed feature comparison between the different licenses, refer to our https://www.elastic.co/subscriptions[subscriptions page].
|
||||
====
|
||||
|
||||
==== Send requests to Elasticsearch
|
||||
|
||||
You send data and other requests to Elasticsearch through REST APIs.
|
||||
You can interact with Elasticsearch using any client that sends HTTP requests,
|
||||
such as the https://www.elastic.co/guide/en/elasticsearch/client/index.html[Elasticsearch
|
||||
language clients] and https://curl.se[curl].
|
||||
|
||||
===== Using curl
|
||||
|
||||
Here's an example curl command to create a new Elasticsearch index, using basic auth:
|
||||
|
||||
[source,sh]
|
||||
----
|
||||
curl -u elastic:$ELASTIC_PASSWORD \
|
||||
-X PUT \
|
||||
http://localhost:9200/my-new-index \
|
||||
-H 'Content-Type: application/json'
|
||||
----
|
||||
// NOTCONSOLE
|
||||
|
||||
===== Using a language client
|
||||
|
||||
To connect to your local dev Elasticsearch cluster with a language client, you can use basic authentication with the `elastic` username and the password you set in the environment variable.
|
||||
|
||||
You'll use the following connection details:
|
||||
|
||||
* **Elasticsearch endpoint**: `http://localhost:9200`
|
||||
* **Username**: `elastic`
|
||||
* **Password**: `$ELASTIC_PASSWORD` (Value you set in the environment variable)
|
||||
|
||||
For example, to connect with the Python `elasticsearch` client:
|
||||
|
||||
[source,python]
|
||||
----
|
||||
import os
|
||||
from elasticsearch import Elasticsearch
|
||||
|
||||
username = 'elastic'
|
||||
password = os.getenv('ELASTIC_PASSWORD') # Value you set in the environment variable
|
||||
|
||||
client = Elasticsearch(
|
||||
"http://localhost:9200",
|
||||
basic_auth=(username, password)
|
||||
)
|
||||
|
||||
print(client.info())
|
||||
----
|
||||
|
||||
===== Using the Dev Tools Console
|
||||
|
||||
Kibana's developer console provides an easy way to experiment and test requests.
|
||||
To access the console, go to **Management > Dev Tools**.
|
||||
To access the console, open Kibana, then go to **Management** > **Dev Tools**.
|
||||
|
||||
