The transition from Dockerized applications to orchestrated deployments using Kubernetes represents a significant advancement in managing software environments, offering scalability and high availability. This tutorial guides users through deploying a Dockerized application consisting of a web server, database, and key-value store to a Kubernetes (K8s) cluster using Google Kubernetes Engine (GKE). It demonstrates the use of Kong's Kubernetes Ingress Controller to manage external access and introduces the integration of Kong plugins for enhanced functionality. The process involves creating a GKE cluster, configuring it using kubectl, and setting up an ingress controller to facilitate communication between the external world and the K8s services. Additionally, the tutorial covers the implementation of cert-manager for HTTPS support and the application of plugins such as HTTP Log and Correlation ID to customize traffic handling and enhance observability within the Kubernetes environment. This walkthrough provides a comprehensive foundation for deploying Dockerized applications to Kubernetes with advanced features like secure access and logging capabilities.
