Explain container image flow in CI/CD
Scenario
Describe the end-to-end process within a typical CI/CD pipeline for building and deploying a containerized service.
Key Aspects to Cover
- Image Build Process (CI Phase): Explain how a container image is constructed, detailing concepts such as layers, build cache utilization, and the build context.
- Image Tagging and Registry Upload: Describe the mechanisms for tagging a built image and subsequently pushing it to a container registry.
- Image Pulling by Runtimes/Nodes: Detail how container runtimes or orchestration nodes retrieve the image, including considerations for authentication, local caching, and image digests for integrity.
- Security Checks: Outline essential security measures that should be integrated into the pipeline, such as image scanning, Software Bill of Materials (SBOM) generation, and image signing.
- Failure Modes and Mitigation: Identify common failure scenarios within this pipeline and discuss strategies for detection, recovery, and prevention.
