Docker solves the problem of environment isolation on the same machine and improves the efficiency of operations and deployment. Vagrant gives developers a unified, near-fully-isolated environment for development and testing. This article mainly discusses how to build a Django development environment with Vagrant. Versions: VirtualBox 5.0, Vagrant 1.8. 1. Basic

1. Directory Structure The django-devops-uwsgi directory holds the image build files that package uWSGI and Django. It installs the necessary packages such as uWSGI, pip, and virtualenv into the image. When a container is created from the image, the start.sh script runs: it creates the Python virtual runtime environment, installs the dependency packages from Django’s requirements.

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. Other request URLs are forwarded to uWSGI for processing via the uwsgi_pass configuration.

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. Docker Compose positions itself as ‘defining and running complex applications with Docker’.
