Have you worked with Docker?

Yes, I have worked with Docker. I used it for containerizing applications and test environments, which allows for quick deployment and isolation of services. For example, I created a Dockerfile for automatically building an image with a test application and ran containers with the necessary dependencies for integration testing.

Example Dockerfile for a test environment:

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

This approach simplifies environment setup and ensures test stability regardless of developers' local configurations.
