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 Prometheus Adapter
Prometheus Adapter is an implementation of the Kubernetes Custom and External Metrics APIs. It allows the Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA) to scale workloads based on metrics stored in Prometheus, by translating Prometheus queries into the metrics that the Kubernetes API server exposes.
The adapter runs as a Kubernetes API server extension: it registers the custom.metrics.k8s.io and external.metrics.k8s.io API groups and serves metric values by querying Prometheus. It uses in-cluster configuration by default to talk to the Kubernetes API and to your Prometheus instance, and supports configurable discovery and metric mapping rules so you can expose the right Prometheus metrics to HPAs.
For configuration details and walkthroughs, see the Prometheus Adapter documentation.
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.
