Images for Elasticsearch Install Validation

Install Elasticsearch with Docker

Pulling the image
Obtaining Elasticsearch for Docker is as simple as issuing a docker pull command against the Elastic Docker registry.
$ docker pull docker.elastic.co/elasticsearch/elasticsearch:7.15.0

Starting a single node cluster with Docker
To start a single-node Elasticsearch cluster for development or testing, specify single-node discovery to bypass the bootstrap checks:
$ docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.15.0
