Description: An Ingress resource in Kubernetes is an object that defines how external HTTP/S traffic should be directed to services within a cluster. This resource acts as an entry point for external requests, allowing users to access applications deployed in the Kubernetes cluster. Ingress resources are fundamental for traffic management, as they enable the configuration of routing rules based on URL, host, and other parameters. Additionally, they can include features such as TLS termination, allowing secure connections to be handled. Ingress Controllers are components that implement the rules defined in Ingress resources and can be of different types, such as NGINX, Traefik, or various cloud provider-specific controllers. The flexibility and customization capabilities of Ingress resources make them an essential tool for microservices architectures, where multiple services can be exposed through a single entry point, thus optimizing traffic management and improving the security and performance of applications.
