August 2025 monthly summary for the Heroku CLI project focused on delivering container registry compatibility improvements for Docker deployments. Implemented disabling attestations and SBOMs for the container registry when using Docker 24.0.0+, and enforced amd64 images for builds/pushes from non-amd64 architectures (e.g., aarch64). This work reduces registry feature mismatches, improves deployment reliability across multi-arch environments, and enhances performance by avoiding unsupported steps. The change aligns with customer needs for stable Docker-based workflows and reduces CI/CD failures related to registry interactions. Overall impact includes smoother multi-arch deployments, fewer registry-related failures, and faster image pushes. Technologies/skills demonstrated include Docker, container registries, multi-arch builds, SBOM/attestation management, CLI code changes, testing across architectures.
