Description: An ingress subdomain is a specific subdomain used to route traffic to a defined service within an ingress resource in a container orchestration system, such as Kubernetes. This concept is fundamental in managing containerized applications, as it allows developers and system administrators to define how external traffic should be directed to internal services. Ingress subdomains are part of the configuration of an ingress controller, which acts as an entry point for HTTP and HTTPS requests. By using subdomains, traffic can be organized more efficiently, allowing different services to be accessible through different domain names or subdomains. This not only improves clarity and traffic management but also enables the implementation of specific security and authentication policies for each subdomain. Additionally, ingress subdomains facilitate the implementation of DevOps practices, such as continuous deployment and continuous integration, by allowing multiple versions of a service to coexist and be accessible through different subdomains. In summary, ingress subdomains are a powerful tool in container orchestration that optimizes how traffic is managed to applications deployed in a cluster.
