github-actions-secure-container-build

Build secure, multi-architecture container images in GitHub Actions using Wolfi runtime, native ARM64 runners, and Podman. Use this skill when users need to (1) set up GitHub Actions workflows for secure container builds, (2) create Containerfiles with security best practices (Wolfi runtime, non-root users, minimal attack surface), (3) build multi-arch images using native ARM64 runners (not QEMU), (4) implement Python/uv, Bun, or Node.js/npm container builds with security-hardened runtime, or (5) optimize container build performance and security in GitHub Actions CI/CD pipelines.
