khu-mcl-docker

0. FYI

Because this repository was designed for a lab seminar, code efficiency aspects were not considered.

So, please keep in mind that this is simply a repository for learning 'Docker'.

1. app.py

This script runs a simple web server using 'Flask' and demonstrates a client sending a message to the server.

The server runs in a new thread, while the client sends a message to the server after a certain delay and prints the server's response.

2.Dockerfile

Environment variables are used to set the server's port and the client's message at the time running 'Docker Container'.

USER_NAME variable will be set while building docker-image.

3. How to use

1. Clone the repository

2. Move to khu-mcl-docker

cd khu-mcl-docker

3. Build Docker Image

docker build --build-arg USER_NAME=$USER -t flask_app:latest .

4. Run the Container

docker run -p 3000:5000 -e FLASK_PORT=5000 -e CLIENT_MESSAGE="Hello from $USER!" --name flask_server flask_app:latest

5. Enter into the Container

docker exec -it flask_server /bin/bash

# Exit Container
exit
