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.

About Trust Manager Package
Trust Manager is a Kubernetes operator from the Cert Manager project that distributes trust bundles across clusters. It assembles X.509 CA certificates from multiple sources and syncs them into ConfigMaps or Secrets in every namespace where your workloads need them.
The Trust Manager Package image is a companion container that provides the default CA certificate bundle used by Trust
Manager. It contains a small Go binary and a JSON-formatted trust bundle derived from the Debian ca-certificates
package. When trust-manager starts, it runs this image as an init container to copy the CA bundle into the trust-manager
pod, which then distributes it to workloads across the cluster via Bundle resources with useDefaultCAs: true.
This image is versioned based on the Debian ca-certificates package version and is available in variants for different
Debian releases (bookworm, trixie).
