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 Istio Install CNI
Istio Install CNI is a specialized component responsible for installing and configuring the Istio Container Network Interface (CNI) plugin on Kubernetes nodes. This plugin is a critical infrastructure component that enables traffic capture and redirection without requiring elevated privileges (NET_ADMIN capability) in the application sidecar proxy.
The CNI plugin replaces the traditional init-container approach that previously required running with elevated security capabilities. By performing network configuration at the node level during pod startup, Istio CNI allows application containers to run with minimal required privileges, significantly improving security posture.
Key responsibilities of Istio Install CNI:
- CNI Plugin Installation: Deploys the Istio CNI plugin binary to Kubernetes nodes
- Network Configuration: Configures iptables rules and network namespaces for traffic redirection
- Pod Traffic Capture: Intercepts inbound and outbound traffic for sidecar proxy injection
- Privilege Reduction: Eliminates the need for elevated capabilities in application containers
- Automatic Node Setup: Automatically configures nodes as they join the cluster
- Configuration Management: Handles CNI configuration file generation and updates
- Node Daemonset Operation: Runs as a DaemonSet to ensure coverage across all cluster nodes
- Compatibility Management: Ensures compatibility with various Kubernetes distributions and container runtimes
