1. Deployment Architecture The program processing flow when a browser visits a page: (1) The browser sends a request to Nginx. If it matches a static URL on the Nginx side, for example files such as js, css, or 404.html under the /static directory, Nginx returns the file directly.

1. Basic Concepts Docker Compose is a Docker tool for defining and running complex applications. With Docker Compose, you can define a multi-container application in a single file, then use a single command to start your application and finish all the preparation work.

1. Basic Concepts A Dockerfile is a collection of instructions for building a Docker image. Docker reads Dockerfile instructions to build an image automatically. A Dockerfile is similar to a Makefile: both are text files that organize all the instructions in the order the image is built. The command to build a Docker image:

Vagrant is suited to managing virtual machines, while Docker is suited to managing application environments. To better simulate a real runtime environment, this series of articles uses Docker and Docker Compose to build a development environment of Nginx + uWSGI + Django + MySQL + Redis + Rabbit. 1. Basic

1. Characteristics of Fixtures Fixtures are a new way to provide initial data, and they are used by Django’s test framework to handle test data for unit tests. Unlike SQL files, a fixture can provide a serialized file that Django’s serialization system understands; it is read, automatically converted into the corresponding model, and then saved into the database.
