One of the core technologies that many Docker environments rely on is service discovery. Service discovery allows an application or component to discover information about their environment and neighbors. This is usually implemented as a distributed key-value store, which can also serve as a more general location to dictate configuration details. Configuring a service discovery tool allows you to separate your runtime configuration from the actual container, which allows you to reuse the same image in a number of environments. In this guide, we’ll discuss the benefits of service discovery within a clustered Docker environment. We will focus mainly on general concepts, but provide more specific examples where appropriate.
