GitHub Actions Container Build

Build multi-architecture container images in GitHub Actions using Podman and native ARM64 runners.

Core Principles

Choose Your Workflow

CRITICAL: Ask these questions before generating any workflow.

Question 1: Is your GitHub repository public?

• Yes → Use github-actions-workflow-matrix-build.yml (free standard ARM64 runners, 10-50x faster)
• No → Go to Question 2

Question 2: Do you have GitHub Team/Enterprise + willing to pay for ARM64 builds?

• Yes → Use ARM64 larger runners (custom setup required, paid per minute)
• No → Use github-actions-workflow-qemu.yml (free QEMU emulation, slower but works on free tier)
