Created containers for:

  • Redis

Applied multi-stage builds to reduce image size and used .dockerignore.

Here is an example Dockerfile for a simple Python web application:

# Using multi-stage build
FROM python:3.9-slim as builder
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

FROM python:3.9-slim
WORKDIR /app
COPY --from=builder /app /app
COPY . .
EXPOSE 8000
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
