SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill ensures that every container image is tagged with its exact Git commit SHA, providing an immutable and traceable link between running code and its source, which is crucial for incident response and debugging.

Core Features & Use Cases

  • Immutable Tagging: Enforces the use of full Git SHAs as the primary image tag.
  • Traceability: Establishes a clear chain from a running container back to the specific commit in source control.
  • Incident Response: Dramatically speeds up debugging by instantly identifying the exact code version running in production.
  • Use Case: When an incident occurs at 3 AM, you can immediately determine the precise code version by looking at the running container's image tag, avoiding time-consuming log searches.

Quick Start

Use the container-image-tagging skill to build and tag a Docker image with the current Git SHA.

FAQPage Schema
How do I tag Docker images with Git SHA for traceability?

Tagging Docker images with Git SHA involves extracting the current commit hash and applying it as the primary immutable tag during your build process. This establishes a traceable link between containers and source code.

Why should I avoid using the latest tag for container images?

Avoiding the latest tag for container images prevents mutable tag issues where a single tag points to different code over time. Using immutable Git SHA tags instead ensures you can instantly identify the exact code version during an incident.

What is the best way to add build metadata to container images?

The best way to add build metadata to container images is by using OCI labels. This approach embeds traceability information directly within the image, providing build details and source control references for incident response.

Does this container tagging strategy work across AWS, GCP, and Azure?

Yes, this container tagging strategy provides cloud provider-specific configurations and guidance for registry lifecycle policies across AWS, GCP, and Azure. It ensures Git SHA tagging and OCI labels function correctly within your specific cloud environment.

How do CI/CD pipelines automate Git SHA tagging for incidents?

CI/CD pipelines automate Git SHA tagging by capturing the commit hash during the build stage and applying it as the image tag. This allows you to immediately trace a running container back to the exact code version during an incident.
