Dockerfile
This project is a collection of best practices and curated templates for building secure, stable, and production-ready Docker images. It provides standards for OCI image optimization and a guide for implementing industry-standard configurations in container environments.
The repository offers specific patterns for security hardening, such as implementing non-root user execution with static IDs to prevent host privilege escalation. It also provides structural templates for multi-stage builds to separate build-time dependencies from the final runtime environment.
Additional capabilities cover container process management using lightweight init systems to handle system signals and prevent zombie processes. The project also includes methods for ensuring build reproducibility through version-pinned base images and network configurations to resolve DNS failures across legacy Linux and macOS runtimes.
Features
- Container Image Building - Provides a comprehensive set of standards and templates for building secure and optimized production container images.
- Docker Image Building - Provides a comprehensive set of standards and templates for building secure, production-ready Docker images.
- Multi-Stage Container Builds - Provides structural patterns for multi-stage builds to reduce attack surface and final image size.
- Multi-Stage Build Pipelines - Ships curated multi-stage build templates that separate build-time dependencies from the final runtime environment.
- Image Optimization Standards - Establishes guidelines for pinning base images and structuring entrypoints to ensure efficient and reproducible OCI builds.
- Hardened Container Images - Provides patterns for creating pre-configured, secure container images designed for production environments.
- Non-Root Process Identities - Implements non-privileged user identities with static IDs to prevent host privilege escalation.
- Container Security Hardening - Hardens container security by restricting application privileges and implementing non-root execution.
- Reproducible Build Environments - Ensures consistent container builds by pinning base image versions and managing dependency updates.
- Base Image Pinning - Locks specific base image tags to ensure consistent builds and prevent breaking changes from upstream updates.
- OCI Container Process Management - Manages process lifecycles and signal propagation within OCI compliant container runtimes.
- Reproducible Build Systems - Ensures consistent and deterministic image builds across environments by pinning base image versions.
- Process Signal Forwarding - Implements mechanisms to propagate termination signals from the container init process to child processes.
- Container Init Process - Uses a lightweight init system as PID 1 to handle system signals and manage zombie processes.
