What problem does it solve?

Professionals building modern containerized applications face complex, multi-step workflows that combine OCI specifications, sophisticated BuildKit caching strategies, multi-architecture images, and security-hardening practices. This Skill provides a concise, production-aware guide to reason about containers at the kernel and runtime layer, enabling reproducible builds and safer deployments.

Core Features & Use Cases

• Deep OCI & runtime understanding: cover image specs, runtime specs, and distribution APIs to reason about images and bundles.
• BuildKit mastery: cache mounts, secrets, SSH mounts, and multi-stage builds to optimize CI/CD pipelines.
• Security hardening & signing: rootless container principles, seccomp, AppArmor/SELinux, and cosign-based image signing for supply chain security.
• Multi-arch and runtime diversity: support for container runtimes like containerd, CRI-O, gVisor, Kata, and cross-platform builds.
• Use Case: Design a secure, production-ready container pipeline that builds small, reproducible images for ARM64 and x86_64 with verifiable signatures and minimal attack surface.

Quick Start

Start by following the guided setup to build a multi-arch, rootless container image using BuildKit and cosign verification.
