A Passing Docker Build Does Not Guarantee a Deployable Container Image
A container image can build and push to a registry successfully while still failing at runtime, creating a dangerous gap in CI/CD pipelines. In one observed case, a misconfigured Uvicorn command pointed to the wrong application target, causing the container process to exit after deployment without ever becoming healthy. By the time the defect surfaced, it was buried under infrastructure noise from orchestrators, health-check timeouts, and potential rollbacks. The recommended fix is to run the exact built image as a container in CI and require a minimal health endpoint to respond before the image is published to any registry. This ensures the artifact proven during testing is identical to the one shipped, closing the gap between successful packaging and verified runtime startup.
