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.

About Tekton CLI
The Tekton CLI (tkn) is the command line interface for Tekton, the Kubernetes-native framework for building CI/CD
systems. It manages Tekton Pipelines, Tasks, and Triggers resources against a cluster and packages Tekton resources as
OCI bundles.
Key Features
- Pipeline and Task Management: Create, start, describe, list, and delete Pipelines, Tasks, PipelineRuns, TaskRuns, and CustomRuns
- Log Streaming: Follow logs from running or completed pipeline and task runs
- Triggers Support: Manage EventListeners, TriggerBindings, ClusterTriggerBindings, and TriggerTemplates
- OCI Bundles: Package Tekton resources into OCI images and list bundle contents with
tkn bundle - Tekton Hub: Search and install reusable Tasks and Pipelines from Tekton Hub
- Shell Completion: Generate completion scripts for bash, zsh, fish, and PowerShell
Common Use Cases
- Pipeline Operations: Start pipelines and follow their logs from a terminal or CI job
- In-Cluster Automation: Run as the step image inside a Tekton
Taskto drive Tekton from a pipeline - Debugging: Describe runs and inspect step status when a pipeline fails
- Resource Distribution: Publish and inspect Tekton resources as OCI bundles in any registry
- GitOps Workflows: Apply and inspect Tekton resources as part of a delivery pipeline
Getting Started
The tkn CLI reads cluster credentials the same way kubectl does, from a kubeconfig file or an in-cluster
ServiceAccount. Common operations include:
tkn version- Print the client versiontkn pipeline list- List Pipelines in the current namespacetkn pipeline start- Start a Pipeline and optionally follow its logstkn pipelinerun logs -f- Follow the logs of a PipelineRuntkn task describe- Show details for a Tasktkn bundle push- Package Tekton resources into an OCI bundletkn bundle list- List the resources inside an OCI bundletkn hub search- Search Tekton Hub for reusable Tasks and Pipelines
This Docker Hardened Image provides a secure, minimal environment for running Tekton CLI operations in containerized
workflows, Tekton Task steps, and CI/CD pipelines.
