1 Background 1.1 Docker introductionDocker is a container engine project based on lightweight virtualization technology from Docker, the entire project is based on the go language and complies with the Apache 2.0 protocol. Today, Docker can quickly automate deployment of applications within the container, and can provide container resource isolation and security
: developers only care about the applications running in the container, and OPS only need to care about how to manage the containers. The purpose of Docker design is to strengthen the development environment for developers writing code and the consistency of application deployment to the production environment. 4. Docker provides a fast and efficient development lifecycle: One of the goals of

words, I think the details of microservices go beyond the scope of traditional unit tests, which is what this chapter addresses. Anyway, I would like to highlight a few points: Unit testing as usual: Your business logic, converters, validators, and so on are nothing magical, because they all run in the context of microservices. Integration components, such as communicating with other services, sen
era of having to write a WSDL file has passed. REST promises us a practical, simple and standardized approach to resource management. REST uses the HTTP protocol to define the specific Web action types that are being executed. REST encourages us to use HTTP error response codes to more accurately describe the server's response status. And in most cases, this method works well, and there is no problem. But like all good things, rest has a lot of shortcomings and drawbacks, and I'm not going to g
engine (no separate Web server required), the service should start on its own at the command line, and be accessed immediately through the exposed HTTP port.Concurrency: To initiate more micro-service instances to scale horizontally when demand increases.Can be arbitrarily disposed of: you can start and stop as needed.The development environment is equivalent to the production environment: minimizing the gap between all the environments in which the service runs.LOG: Use the tool to log and vie

Editor's note "This is the fourth article on creating an app family using a microservices architecture." The first chapter introduces the model of MicroServices architecture and discusses the advantages and disadvantages of using microservices architecture. The second and third articles describe the communication mechanisms within the
This is a creation in Article, where the information may have evolved or changed. In the previous article, we created a user service that saved some users. Now we look at how to safely save the user password in the user service, and write several functions through the microservices to authenticate the user and release the security token. Note that I have now split our service into several different warehouses. I think it's easier to deploy. At first

Use Python, RabbitMQ, and Nameko to implement microservicesGuide"Microservices are a new wave"-nowadays, splitting projects into multiple independent and scalable services is the best choice to ensure code evolution. In the world of Python, there is a framework called "Nameko", which makes the implementation of microservices simple and powerful. In recent years, "microservice architecture" has sprung up. It
