The article is the second installment of a three-part tutorial series on deploying the ELK stack on Kubernetes using Elastic Cloud on Kubernetes (ECK). It details the process of setting up Elasticsearch and Kibana within a Kubernetes environment, focusing on the use of Kubernetes Custom Resource Definitions (CRDs) and Operators to manage Elasticsearch components efficiently. The guide provides instructions on configuring Elasticsearch nodes, securing sensitive data with Kubernetes Secrets, and making services accessible externally via NodePort. It also covers the installation and configuration of Kibana, alongside the deployment of necessary plugins to expand Elasticsearch's functionality. The article emphasizes best practices for security, such as avoiding storing sensitive data in non-secure parts of the filesystem and using valid SSL/TLS certificates in production environments, while also providing a brief overview of setting up a basic Kubernetes Dashboard for visual management.
