How to Deploy Elasticsearch on Kubernetes

Elasticsearch is a powerful search and analytics engine used for storing, searching, and analyzing data in real-time. It is highly scalable and efficient, making it a popular choice for applications that require fast and reliable search capabilities.

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. Combining Elasticsearch with Kubernetes can provide a highly scalable and reliable solution for managing large amounts of data.

In this article, we will walk through the steps required to deploy Elasticsearch on Kubernetes.

  1. Prerequisites
  2. Deploy Elasticsearch on Kubernetes
  3. Verify Elasticsearch deployment
  4. Additional Elasticsearch configurations


Before we begin, make sure you have the following prerequisites installed on your system:

  1. A Kubernetes cluster
  2. kubectl command-line tool
  3. Elasticsearch image or Dockerfile
  4. Elasticsearch configuration file

Deploy Elasticsearch on Kubernetes:

Follow these steps to deploy Elasticsearch on Kubernetes:

Step 1: Create a namespace for Elasticsearch

kubectl create namespace elasticsearch

Step 2: Create a secret for Elasticsearch password

kubectl create secret generic elasticsearch-pw --from-literal=password=yourpassword -n elasticsearch

Step 3: Create a configmap for Elasticsearch configuration

kubectl create configmap elasticsearch-config --from-file=elasticsearch.yml -n elasticsearch

Step 4: Deploy Elasticsearch using a deployment file

kubectl apply -f elasticsearch-deployment.yaml -n elasticsearch

Step 5: Expose Elasticsearch service

kubectl expose deployment elasticsearch --port=9200 -n elasticsearch

Verify Elasticsearch deployment:

To verify that Elasticsearch is running, run the following command:

kubectl get pods -n elasticsearch

You should see output similar to the following:

elasticsearch-6c9874f7b4-xslb8 1/1 Running 0 1m

Additional Elasticsearch configurations:

You can modify Elasticsearch configurations by editing the Elasticsearch configuration file and applying the changes using the following command:

kubectl apply -f elasticsearch-deployment.yaml -n elasticsearch

For example, to set the number of Elasticsearch replicas to 3, update the replicas value in the deployment file and run the following command:

kubectl apply -f elasticsearch-deployment.yaml -n elasticsearch

In this article, we have walked through the steps required to deploy Elasticsearch on Kubernetes. By following these steps, you can easily deploy Elasticsearch on Kubernetes and take advantage of its scalability and reliability.
