Still debugging Dockerfiles only after they hit staging? In 2025, that’s no longer acceptable. Build Checks — now built into Docker CLI and GitHub Actions — catch issues before the first layer is even built. CI becomes faster, safer, and far less noisy. ✅ What Build Checks Do for You Flag bad practices before anything runs (docker build --check .) Show exact Dockerfile line, with rule name and docs link Allow # check= inline overrides (skip noisy rules per file) Run locally, in CI, and even pre-commit — all lightning-fast
