Explain container image flow in CI/CD
Quick Overview
This question evaluates understanding of the container image lifecycle within CI/CD pipelines, covering build mechanics (layers, cache, build context), tagging and registry interactions, image distribution and pulling behavior (authentication, caching, digests), security controls (vulnerability scanning, SBOM generation, signing), and common failure modes. It is commonly asked to gauge operational and security competence in the Software Engineering Fundamentals/DevOps domain and measures both conceptual understanding and practical application of pipeline design and runtime image management.

Scenario
Walk through what happens in a typical CI/CD pipeline that builds and deploys a containerized service.
Questions
- During CI, how is a container image built (layers, cache, build context)?
- How is the image tagged and uploaded to a registry?
- How do runtimes/nodes pull the image (auth, caching, digests)?
- What security checks should be included (scanning, SBOM, signing)?
- What failure modes are common and how do you mitigate them?
