Fix a docker file and minimize the size

We are looking for an experienced DevOps Engineer to optimize our existing Docker setup for a Python application that uses Playwright. The primary goal is to significantly reduce the Docker image size, improve build performance, and implement containerization best practices without affecting application functionality. Responsibilities: * Review and optimize the existing Dockerfile. * Reduce Docker image size using multi-stage builds and lightweight base images. * Optimize installation of Python dependencies and Playwright browsers. * Remove unnecessary packages, caches, and temporary files. * Improve Docker layer caching to speed up CI/CD builds. * Configure the container to run as a non-root user. * Optimize startup time and overall container performance. * Ensure compatibility across development and production environments. * Document all changes and provide recommendations for future maintenance. Required Skills: * Strong experience with Docker and container optimization. * Python application deployment and dependency management (pip, Poetry, or uv). * Experience with Playwright and browser dependencies. * Linux system administration. * Multi-stage Docker builds and Docker BuildKit. * Docker Compose. * CI/CD pipelines (GitHub Actions, GitLab CI/CD, Jenkins, or Azure DevOps). * Container security best practices. Nice to Have: * Kubernetes or Docker Swarm. * Docker Slim, Distroless, or Chainguard Images. * Image analysis tools such as Dive. * Security scanning tools like Trivy, Grype, Snyk, or Docker Scout. * Infrastructure as Code (Terraform or Ansible). * Experience with AWS, Azure, or Google Cloud. Deliverables: * Optimized Dockerfile. * Reduced Docker image size. * Faster build times. * Documentation of all optimization changes. * Recommendations for further improvements to our containerization and CI/CD workflow. Please include in your proposal: * Examples of Docker optimization projects you've completed. * The largest percentage reduction in image size you've achieved. * Your preferred tools and approach for optimizing Python + Playwright Docker images. * Estimated timeline and cost for this project.
