Docker Swarm Service Discovery

Docker Swarm Service Discovery is a feature that helps different applications running in a Docker environment find and communicate with each other. In a Docker Swarm, multiple containers can work together as a single unit or service. Service discovery allows these containers to automatically detect where other necessary services are located, without requiring manual configuration. This means that if a container needs to talk to another one, it can easily locate it through a simple name rather than needing to know specific addresses or ports, facilitating smoother operation and management of complex applications.
