Service discovery is crucial in Kubernetes because it allows microservices to communicate effectively, helping maintain a stable and responsive environment.
In Kubernetes, services abstract a group of pods, making them accessible via a single DNS name or IP address, facilitating easier communication between applications.
When a service is created, Kubernetes automatically assigns a stable IP address (ClusterIP) and a DNS name that allows for simplified application interactions.
CoreDNS manages the resolution of DNS names to ClusterIP, ensuring that communication between pods is seamless and efficient without needing to know pod specifics.
