Problem

Scenario

You are setting standards for how your team builds and publishes container images for services that will run in production. You want to make sure image creation is secure from the start so vulnerabilities, leaked secrets, and unsafe base images do not enter the delivery pipeline.

Question

What security best practices do you follow when creating Docker images, especially in a CI/CD workflow, and how do you reduce deployment risk if a bad image still gets promoted?
