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 cert-manager-webhook
cert-manager-webhook is a Kubernetes component that provides an admission webhook used by cert-manager to validate and mutate cert-manager resources. It ensures that Certificate, Issuer, and related custom resources created in the cluster are syntactically and semantically valid before being persisted by the Kubernetes API server.
As part of the cert-manager ecosystem, the webhook enforces policy and consistency across cert-manager resources. It performs admission control checks, applies default values where necessary, and validates configuration details to prevent misconfigurations that could lead to certificate issuance errors or security issues.
The cert-manager webhook is deployed automatically alongside cert-manager and communicates securely with the Kubernetes API server using TLS. Certificates used by the webhook are automatically managed and renewed by cert-manager itself, ensuring ongoing secure communication without manual certificate handling.
