Deploying and Exposing Go Apps with Kubernetes Ingress, Part 1
- Kubernetes Ingress is crucial for managing external access to services, offering advanced traffic control features like path-based routing, SSL, and load balancing.
- Ingress vs. Services: Ingress improves routing capabilities over Services by enabling path-based and host-based routing for more sophisticated traffic management.
- Introduced in Kubernetes v1.1, Ingress became stable in v1.19, providing a crucial tool for modern web apps needing smarter routing and security.
- The tutorial demonstrates building Go services (API and Web) deployed with Kubernetes Ingress for routing external HTTP traffic based on URL paths.
- API and Web services are containerized, Kubernetes cluster is set up using Kind, NGINX Ingress controller is deployed, and Ingress rules are defined for routing.
- NGINX Ingress controller is implemented for managing routing and load balancing in the Kubernetes cluster.
- Deployment configurations for API and Web services are created along with respective Service definitions for internal access.
- Ingress resources are set up using defined routing rules based on URL paths to direct traffic to the appropriate services.
- Verification steps ensure all components are running, and testing with cURL confirms the expected service responses through Ingress routing.
- The project showcases the power of Ingress in managing complex traffic patterns in microservices architectures, enhancing external access and routing capabilities.
