Dockerize the Python app and deploy it on appserver, follow these steps:

This assumes you have a python app under /python_app/

Step 1: Create the Dockerfile

Navigate to the /python_app/ directory:

cd /python_app

Create the Dockerfile:

nano Dockerfile

Add the following content:

# Use a Python image as the base
FROM python:latest

# Set the working directory
WORKDIR /python_app

# Copy the dependencies file into the container
COPY src/requirements.txt .

# Install dependencies
RUN pip install --no-cache-dir -r requirements.txt

# Copy the application files into the container
COPY src/ .

# Expose port 8087
EXPOSE 8087

# Run the Python application
CMD ["python", "server.py"]

Save and exit.

Step 2: Build the Docker Image

Run the following command to build the Docker image:

docker build -t nautilus/python-app .

Step 3: Run the Container

Now, create and start the container with the required port mapping:

docker run -d --name pythonapp_nautilus -p 8099:8087 nautilus/python-app

-d: Runs the container in detached mode.
--name pythonapp_nautilus: Sets the container name.
-p 8099:8087: Maps host port 8099 to container port 8087.

Step 4: Verify the Running Container

Check if the container is running:

docker ps

Confirm that logs show no errors:

docker logs pythonapp_nautilus

Step 5: Test the Deployment

Run the curl command to verify the app:

curl http://localhost:8099/

If you receive a response, the app is successfully deployed! 🚀 Let me know if you need adjustments or troubleshooting.
