In this tutorial, I'll show you how to install Elasticsearch using Docker. Elasticsearch is a powerful search and analytics engine that's essential for many modern applications. Docker allows us to set up Elasticsearch quickly and easily in a containerized environment.

Here are the steps to install Elasticsearch using Docker:
Pull the Elasticsearch Docker Image: We'll start by pulling the Elasticsearch image from the official Elastic repository. Open your terminal or command prompt and enter the following command:
bash
Copy code
docker pull docker.elastic.co/elasticsearch/elasticsearch:8.9.0
Create a Docker Network: Elasticsearch needs a network for communication. Let's create a Docker network named "elastic":
lua
Copy code
docker network create elastic
Run the Elasticsearch Container: Now, let's run the Elasticsearch container using the image we pulled earlier. We'll name the container "es01," connect it to the "elastic" network, and map port 9200 (Elasticsearch HTTP) to the host:
css
Copy code
docker run --name es01 --net elastic -p 9200:9200 -it docker.elastic.co/elasticsearch/elasticsearch:8.9.0
Handling Memory Exceptions (if needed): If you encounter memory exceptions while running the container, use the following command to increase the vm.max_map_count value:
arduino
Copy code
wsl -d docker-desktop sh -c "sysctl -w vm.max_map_count=262144"
That's it! You now have Elasticsearch up and running using Docker. You can access Elasticsearch by opening your web browser and navigating to localhost:9200.
