Coding

Preparations

  1. Install Python programming language v3.8.2: https://www.python.org/downloads/
  2. Install Docker: https://docs.python.org/3/installing/index.html#basic-usage
  3. Install Docker-compose: https://docs.docker.com/compose/install/

What you already have after task #5

  1. Flask web application, which can authenticate user with password:
    • Listen on localhost:5000
    • Render authentication form on http://localhost:5000/
    • Return static images and files on http://localhost:5000/static/<image_name>
    • Has secret page for authenticated users on http://localhost:5000/cabinet
  2. Valid usernames and passwords are stored in MongoDB database
  3. Image upload function in cabinet http://localhost:5000/cabinet/
  4. Images are being saved to upload folder

Basic part

  1. Create docker-compose.yml and Dockerfile to run your application in Docker
  2. Move your sources to src directory. Don’t forget to create requirements.txt file
  3. In docker-compose.yml there are gonna be two containers named: mongodb, flask-simple
  4. Setup port forwarding and run docker-compose up. Check that website works on http://localhost:5000

Optimal part

  1. Add persistent volume for MongoDB
  2. Mount upload directory to upload directory inside flask-simple container

Challenging part

  1. Add Nginx which will proxy requests to flask application
  2. Add Redis cache for uploaded images

Deploy

  1. Register on GitHub: https://github.com/
  2. Join our organization: https://github.com/itmo-wad/
  3. You can create new personal repository or use repository for the previous tasks (but don’t remove old files, just append new directories)
  4. Commit and push your sources to GitHub. And don’t forget to describe shortly what have you done in README.md file. Use Markdown format: https://guides.github.com/features/mastering-markdown/

Code-review

  1. Communicate in Telegram chat
  2. Help others to complete the assignment
