Build Level 3
Tamper-evident proof of how and from what sources this image was built. Build Level 3 is the highest the SLSA build track defines.
CycloneDX SBOM + SPDX SBOM
A software bill of materials in both CycloneDX and SPDX formats so it drops straight into your existing tooling. Audit exactly what you're shipping.
A Vulnerability Exploitability exchange document, Docker's assessment of which CVEs actually affect this image and which don't apply, so you can focus on real risk instead of chasing false positives.
Available
A link to everything used to build the image, package source code, Git repos, and build files, so you can audit or reproduce the build and stay compliant with open source licenses.
Every known vulnerability in this image, shown in full rather than hidden. The VEX data flags which ones actually apply, so you can tell real exposure from noise before you ship.
Exactly what changed in this build, down to the package bumps and fixes behind the version you're pulling.
Verifies no keys, tokens, or credentials were accidentally baked into the image.
The image layers were scanned for known malware signatures before publishing.
About Calico Whisker
Calico Whisker is the web UI for viewing network flows in Calico-managed Kubernetes clusters. It is served by nginx and
ships the React application built from the Project Calico monorepo (whisker/). The Tigera Operator deploys this image
when the Whisker component is enabled.
Whisker is the UI container only. Calico also publishes a separate calico/whisker-backend image that provides the
API the UI proxies to at /whisker-backend/. Both components are required for a full Whisker deployment in Kubernetes.
Key responsibilities of Calico Whisker:
- Flow visualization UI: Presents Calico network flow data in a browser-based interface
- Static asset delivery: Serves the built React application over HTTP
- Runtime configuration: Exposes cluster metadata via
/config/config.json, generated from environment variables at startup - Backend proxying: Forwards
/whisker-backend/requests to the Whisker backend service in the cluster
This Docker Hardened Image ships the Whisker static UI and nginx on a minimal static base, matching upstream
calico/whisker entrypoint and port behavior.

About Docker Hardened Images
Docker Hardened Images are built to meet the highest security and compliance standards. They provide a trusted foundation for containerized workloads by incorporating security best practices from the start.
Why use Docker Hardened Images?
These images are published with near-zero known CVEs, include signed provenance, and come with a complete Software Bill of Materials (SBOM) and VEX metadata. They're designed to secure your software supply chain while fitting seamlessly into existing Docker workflows.
