# Python - Flask - Redis Flask is a lightweight and flexible web framework written in Python that is used to build web applications. Flask is classified as a "microframework" because it provides essential tools for creating web applications, but does not impose a specific structure or components, giving developers great flexibility and freedom to choose the libraries and tools they want to use in their projects. On the other hand, Redis (Remote Dictionary Server) is a high-performance open-source, in-memory database used to store, retrieve, and manage data in a key-value pair form. With an in-memory storage architecture, Redis offers exceptional speed and low latency in read and write operations, making it ideal for applications that require fast access to data, such as caches, queue systems, and more. In addition to its ability to store simple data, Redis also supports more complex data structures like lists, sets, maps, and more, making it a powerful tool for developing scalable and high-performance applications. **Project Structure** ``` . ├── compose.yaml ├── app.Dockerfile ├── app ├── requirements.txt └── app.py ``` Application Deployment ``` cd stack/python/flask-redis ``` ``` docker compose up -d ``` Check container status ``` $ docker compose ps ``` Stop and remove the container ``` $ docker compose down ``` **Troubleshooting:** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://help.sitioshispanos.com/menu-principal/guias/docker-hosting/stacks-disponibles/python/python-flask-redis.md?ask= ``` The question should be specific, self-contained, and written in natural language.
