How to Install OpenSearch via Docker on Ubuntu 22.04

Introduction

OpenSearch is an open-source search and analytics suite that provides real-time data exploration. By using Docker for installation, you can quickly set up a local development environment. This guide will walk you through installing OpenSearch via Docker on Ubuntu 22.04, which can be effectively hosted on a Windows VPS UK for optimal performance.

Prerequisites

• An Ubuntu 22.04 server with root access
• Basic knowledge of Linux commands
• Docker and Docker Compose installed on your server

Step 1: Update Your System

Start by updating your package index and upgrading existing packages:

sudo apt update && sudo apt upgrade -y

Step 2: Install Docker

If you haven’t installed Docker yet, you can install it using the following commands:

sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt update
sudo apt install docker-ce -y

Start Docker and enable it to run on boot:

sudo systemctl start docker
sudo systemctl enable docker

Step 3: Install Docker Compose

To install Docker Compose, run the following command:

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Verify the installation:

docker-compose --version

Step 4: Create a Docker Compose File for OpenSearch

Create a new directory for your OpenSearch setup:

mkdir ~/opensearch
cd ~/opensearch

Now, create a docker-compose.yml file:

nano docker-compose.yml

Paste the following configuration into the file:

version: '3.8'

services:
  opensearch:
    image: opensearchproject/opensearch:latest
    container_name: opensearch
    environment:
      - cluster.name=opensearch-cluster
      - node.name=opensearch-node
      - discovery.type=single-node
      - plugins.security.disabled=true
      - opensearch.memory.heap=1g
    ports:
      - 9200:9200
      - 9600:9600
    volumes:
      - opensearch_data:/usr/share/opensearch/data
    networks:
      - opensearch-network

volumes:
  opensearch_data:

networks:
  opensearch-network:

Step 5: Start OpenSearch

To start OpenSearch, run the following command:

docker-compose up -d

This will download the necessary images and start the OpenSearch container.

Step 6: Verify Installation

Once OpenSearch is running, you can verify the installation by navigating to http://your_server_ip:9200 in your web browser. You should see a JSON response indicating that OpenSearch is running.

Step 7: Conclusion

You have successfully installed OpenSearch via Docker on Ubuntu 22.04, providing a powerful search and analytics solution. This setup can greatly benefit from being hosted on a Windows VPS.
