container-hardening

What problem does it solve?

This Skill addresses the critical need to secure containerized applications by implementing best practices for Dockerfiles and runtime configurations, reducing the attack surface and mitigating common vulnerabilities.

Core Features & Use Cases

• Secure Dockerfile Practices: Guides users on building images with minimal privileges, non-root users, and reduced attack vectors.
• Runtime Security Configuration: Provides examples for securing container execution with options like read-only filesystems, dropped capabilities, and user isolation.
• Kubernetes Security Contexts: Demonstrates how to apply security best practices within Kubernetes Pod definitions.
• Image Scanning Integration: Mentions tools for vulnerability scanning to ensure image integrity.
• Use Case: A development team needs to ensure their microservices deployed in Kubernetes are hardened against common security threats. This skill provides the exact configurations and Dockerfile snippets needed.

Quick Start

Apply the provided Dockerfile snippet to your container image build process to enforce non-root user execution.
