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 Cluster API Controller
Cluster API is a Kubernetes sub-project (SIG Cluster Lifecycle) that provides declarative, Kubernetes-style APIs to
provision, upgrade, and operate Kubernetes clusters across infrastructure providers. This image packages the core
controller manager (cluster-api-controller), which reconciles the core Cluster API resources (Cluster, Machine,
MachineSet, MachineDeployment, MachineHealthCheck, and related contracts) and coordinates bootstrap,
control-plane, and infrastructure providers.
The controller is designed to run inside a management cluster, typically installed with clusterctl alongside a
bootstrap provider, a control-plane provider, and one or more infrastructure providers. It serves validating and
defaulting webhooks (port 9443), health probes (port 9440), and a diagnostics/metrics endpoint (port 8443).
