Can I use this with private GitHub repositories?

Yes, the generated Dockerfile and build scripts include logic to handle Personal Access Tokens (CR_PAT) for installing private dependencies securely.

How does the automated versioning work?

It creates a VERSION file and a build-publish.sh script that reads, increments, and tags your Docker images automatically during every build cycle.

Does this skill follow Docker security best practices?

Absolutely. It uses slim base images to reduce attack surfaces, implements a non-root 'appuser', and utilizes .dockerignore to prevent leaking secrets.

What WSGI server does this skill use for production?

The skill uses Gunicorn, which is the industry standard for production Flask deployments, allowing for configurable worker processes to handle concurrent traffic.

Which container registries are supported?

The skill is registry-agnostic and works with any OCI-compliant registry, including Docker Hub, GitHub Container Registry (GHCR), and AWS ECR.

Deployment & DevOps

Containerizes Flask applications for production using Gunicorn, multi-stage Dockerfiles, and automated versioning pipelines.

About

This skill streamlines the transition from local development to production by generating a robust deployment framework for Flask applications. It creates production-grade Dockerfiles using slim base images and non-root users, integrates Gunicorn for high-performance request handling, and implements an automated versioning system. Whether you are publishing to Docker Hub, GHCR, or AWS ECR, this skill ensures your containerized application follows security best practices and maintains a clean, idempotent build-and-publish workflow.

Key Features

Automated versioning system with auto-incrementing builds
Seamless integration for private GitHub dependencies via PAT
Multi-platform build support (linux/amd64) for cloud compatibility
Pre-configured build-and-publish shell scripts for rapid deployment
Production-ready Dockerfile with Gunicorn and security hardening
1 GitHub stars

Use Cases

Containerizing a local Flask API for production deployment on Kubernetes or ECS
Standardizing build pipelines for microservices with automated version tracking
Setting up secure, high-concurrency Python web servers with non-root access
