In Q3 2026, our 12-person platform engineering team slashed container image build times by 45% across 140+ microservices, moving from Docker 28.0.1 to Buildah 2.0.3 – and we didn’t have to rewrite a single Dockerfile to do it. For a team spending $12k/month on CI compute for build jobs, this cut our annual CI costs by $66k, eliminated 18-minute average PR wait times, and removed the Docker daemon as a single point of failure in our pipelines.
