Resolve Vpc Sc Artifact Analysis Scanning Block

What the Solution Is

This solution properly integrates Artifact Analysis and Artifact Registry within a VPC Service Controls (VPC-SC) security perimeter by securing the underlying APIs and establishing private network routing.

How It Resolves the Perimeter Violation

• Service Perimeter Protection: The Container Analysis API (containeranalysis.googleapis.com) and Artifact Registry API (artifactregistry.googleapis.com) are added as protected services inside the VPC-SC perimeter, authorizing authenticated API requests originated within the perimeter boundaries.
• Private DNS Resolution: Artifact Registry repositories use the pkg.dev domain. Configuring DNS resolution for *.pkg.dev to point to restricted.googleapis.com (or private.googleapis.com) routes container pull, push, and scan traffic over private Google Cloud networks rather than public IP routes, preventing perimeter ingress and egress blocks.
• Surfaceless API Handling: The Container Scanning API (containerscanning.googleapis.com) is a surfaceless API that deposits results into Artifact Analysis, meaning it does not require standalone perimeter definition once containeranalysis.googleapis.com is protected.

Key Advantages

• Maintains Zero-Trust Security: Ensures container scans and artifact uploads comply with perimeter boundaries without creating security exceptions.
• Automated Pipeline Execution: Unblocks on-demand scanning (gcloud artifacts docker images scan) inside automated Cloud Build runners.
• End-to-End Encryption and Isolation: Keeps container layers and vulnerability metadata strictly within Google Cloud's private network infrastructure.

Why This Is Optimal

This approach directly targets the root causes of VPC-SC violations for container tooling: missing protected API definitions and unroutable pkg.dev domain requests that otherwise attempt to exit via public internet paths.
