elasticsearchHow can I use Docker Compose to configure and deploy an Elasticsearch cluster?
Docker Compose can be used to configure and deploy an Elasticsearch cluster. Here's an example of how to do this:
version: '3.2'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:7.7.0
environment:
- cluster.name=docker-cluster
- discovery.type=single-node
ports:
- 9200:9200
This example creates a docker-cluster
cluster with a single node. This is done by setting the environment variable cluster.name
to docker-cluster
and the environment variable discovery.type
to single-node
. The image
directive is used to specify the version of Elasticsearch to be used (in this case, 7.7.0). Finally, the ports
directive is used to map the host's port 9200 to the container's port 9200.
Once the configuration is in place, the cluster can be deployed using the docker-compose
command:
$ docker-compose up
This command will start the Elasticsearch cluster.
Parts of the example code:

: maps host ports to container ports
