Review Summary
Your implementation correctly handles all Docker functionality (multi-stage build, ARG/ENV configuration, migration as RUN instruction, and runserver on 0.0.0.0:8080), but INSTRUCTION.md contains the placeholder YOUR_DOCKERHUB_USERNAME in multiple locations where your actual Docker Hub username should be. Per requirement #11, the instructions must contain a link to your personal Docker Hub repository. Since your git clone URL shows VadymMoldovan/devops_todolist, you should replace all instances of YOUR_DOCKERHUB_USERNAME with VadymMoldovan in both INSTRUCTION.md and the Dockerfile (line 6). Once updated, the instructions will correctly direct users to your personal Docker Hub repository for pulling and pushing the image.

The INSTRUCTION.md uses placeholder 'YOUR_DOCKERHUB_USERNAME' instead of an actual Docker Hub username. Per requirement #11, this should contain a link to personal Docker Hub repository with the app image (e.g., 'https://hub.docker.com/r/actualusername/todoapp').

The pull command uses placeholder 'YOUR_DOCKERHUB_USERNAME' - should contain actual Docker Hub username for the repository.

This should be your actual Docker Hub username (e.g., VadymMoldovan) not a placeholder. The requirement states the link should point to your personal Docker Hub repository.

Review Summary
Your implementation fully meets all task requirements. The Dockerfile correctly implements multi-stage builds with ARG for Python version, executes database migrations as a RUN instruction, sets PYTHONUNBUFFERED=1 environment variable, and starts the server on 0.0.0.0:8080. The INSTRUCTION.md file provides complete instructions with the correct Docker Hub repository link and proper build/run/access steps. All 13 checklist items are satisfied with no blocking issues identified. Your solution is approved. The only noted item is the casing difference between vadymmoldovan and VadymMoldovan, but this is functionally equivalent since Docker Hub usernames are case-insensitive. Great work on properly containerizing the Django ToDo application with all required configurations.
