How to do it…

1. If you want to start a vanilla server, just execute the following command:

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.0.0

1. An output similar to the following will be shown:

7.0.0: Pulling from elasticsearch/elasticsearch
 256b176beaff: Already exists

 Status: Downloaded newer image for docker.elastic.co/elasticsearch/elasticsearch:7.0.0

1. After downloading the Elasticsearch image, we can start a develop instance that can be accessed outside from Docker:

docker run -p 9200:9200 -p 9300:9300 -e "http.host=0.0.0.0" -e "transport.host=0.0.0.0" docker.elastic.co/elasticsearch/elasticsearch:7.0.0

You'll see the output of the ElasticSearch server starting.

1. In another window/Terminal, to check if the Elasticsearch server is running, execute the following command:

docker ps

The output will be similar to the following:

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
 b99b252732af docker.elastic.co/elasticsearch/elasticsearch:7.0.0 "/usr/local/bin/dock…" 2 minutes ago Up 2 minutes 0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp gracious_bassi

1. The default exported ports are 9200 and 9300.
