## What it is
A curated Dockerfile template and guide documenting best practices for building production-worthy Docker images, covering non-root users, static high UIDs, pinned image tags, and tini as ENTRYPOINT. It is a copy-paste reference Dockerfile with explanatory comments rather than a tool.

## Use cases
- write a production-ready Dockerfile for my service
- learn Dockerfile security best practices
- run my container as a non-root user safely
- avoid using the latest tag in Docker images
- set up tini as my container entrypoint
- choose a safe UID for containerized processes

## When to choose
- you are writing a new Dockerfile and want battle-tested defaults
- you want a checklist of common container security pitfalls
- you are onboarding developers to container best practices

## When to avoid
- you need a linting or scanning tool rather than written guidance
- your environment requires patterns the guide explicitly advises against
- you need actively maintained or updated recommendations

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, security, developer-tools
- domain: security, developer-tools
- platform: -
- tags: dockerfile, best-practices, containers, oci-images, non-root-user, guide, devops, docker, linux, kubernetes
