Elasticsearch is a powerful search engine widely used for storing and searching data. It can handle large amounts of data and provide fast and accurate search results. Docker is a popular platform for running applications in a containerized environment. In this article, we will guide you through the process of installing Elasticsearch with Docker.

Prerequisites:Before we begin, make sure you have the following prerequisites installed on your system:
- A machine running a Linux distribution such as Ubuntu or CentOS.
- Docker installed on your system.
- Basic knowledge of Docker and Elasticsearch.
Install Docker:To install Docker on your system, follow the steps below:
- Update your package index by running the command:
sudo apt-get update
- Install the dependencies needed by Docker using the command:
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
- Add the Docker GPG key using the command:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
- Add the Docker repository to your system:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
- Update your package index again:
sudo apt-get update
- Finally, install Docker using the command:
sudo apt-get install docker-ce
Install Elasticsearch with Docker:To install Elasticsearch with Docker, follow the steps below:
- Pull the Elasticsearch Docker image from the official Docker Hub repository:
sudo docker pull docker.elastic.co/elasticsearch/elasticsearch:7.12.1
- Create a Docker container from the Elasticsearch image:
sudo docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.12.1
The above command creates a Docker container named "elasticsearch" and exposes ports 9200 and 9300, which are the default ports used by Elasticsearch. It also sets the "discovery.type" parameter to "single-node", which tells Elasticsearch that it is running in a single node cluster.
Verify Elasticsearch installation:To verify that Elasticsearch is installed and running correctly, follow the steps below:
- Open a web browser and enter the following URL:
If Elasticsearch is running correctly, you should see a JSON response containing information about the Elasticsearch cluster.
- You can also verify Elasticsearch by running the following command:
sudo docker ps
This command shows a list of running Docker containers, including the Elasticsearch container.
In this article, we have shown you how to install Elasticsearch with Docker.
