## 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```

```shell

cd khu-mcl-docker

```

3) Build Docker Image

```shell

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

```

4) Run the Container

```shell

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

```shell

docker exec -it flask_server /bin/bash

# Exit Container

exit

```
