What experience do you have in using containerization systems for deploying applications?

I used containerization systems, mainly Docker, to package applications and their dependencies into isolated containers. This ensured portability and consistency of environments when deploying on different servers and in the cloud.

My experience includes:

• Creating Dockerfiles for Python applications
• Configuring multi-container applications with Docker Compose
• Optimizing images to reduce size and speed up builds

Example of a simple Dockerfile for a Python app:

FROM python:3.9-slim
WORKDIR /app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "app.py"]

I am also familiar with Kubernetes basics for container orchestration, which allows scaling applications and managing their lifecycle.
