Using Elasticsearch, Logstash, and Kibana with Go applications

Elasticsearch, an open-source distributed search and analytics engine, is integrated into a tutorial to demonstrate building a basic content management system using Golang. The system allows for creating, reading, updating, and deleting posts, with Elasticsearch providing powerful search capabilities. The tutorial employs the ELK stack by integrating Logstash for data processing and Kibana for data visualization. The setup involves configuring environment variables, managing application dependencies, and using Docker for service orchestration. Additionally, the project includes setting up database migrations with golang-migrate, developing a REST API using the Gin framework, and syncing data between PostgreSQL and Elasticsearch using Logstash. The tutorial culminates in visualizing the Elasticsearch data with Kibana, ensuring a comprehensive understanding of integrating search functionality into a Go application.
