Preface: I received a requirement today. Since most applications in the customer’s cluster require configuration from the configuration center to be pushed to Nacos, I did some research and quickly started a local Nacos using Docker.

What Is Nacos?

Nacos is a new open-source project launched by Alibaba. It is a dynamic service discovery, configuration management, and service management platform that makes it easier to build cloud-native applications.

Nacos is committed to helping you discover, configure, and manage microservices. Nacos provides a simple and easy-to-use set of features that helps you quickly implement dynamic service discovery, service configuration, service metadata, and traffic management.

Nacos helps you build, deliver, and manage microservice platforms more easily and efficiently. Nacos is service infrastructure for building modern service-centric application architectures, such as the microservices and cloud-native paradigms.
