Buffers and routes requests for scaled-to-zero Knative Services. The activator is a data-plane component of Knative Serving. It receives requests for Revisions that have no available pods, reports load to the autoscaler, and forwards traffic once capacity is ready.

What's includedWhy it matters
SLSA Provenance

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.

SBOM

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.

VEX

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.

DHI Image Sources

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.

Changelog

Exactly what changed in this build, down to the package bumps and fixes behind the version you're pulling.

Secrets scan

Verifies no keys, tokens, or credentials were accidentally baked into the image.

Virus scan

The image layers were scanned for known malware signatures before publishing.


About the Knative Serving activator

The activator is a component of the Knative Serving data plane. When a Revision is scaled to zero, or does not yet have enough capacity to handle incoming traffic, requests are routed through the activator. It buffers those requests, reports the demand to the autoscaler so that pods can be scaled up, and forwards the traffic to the Revision once capacity becomes available.

Use this image when you need a hardened, minimal container image for running the Knative Serving activator as part of a Knative Serving deployment.

About Docker Hardened Images

Docker Hardened Images are built to meet the highest security and compliance standards. They provide a trusted foundation for containerized workloads by incorporating security best practices from the start.

Why use Docker Hardened Images?

These images are published with near-zero known CVEs, include signed provenance, and come with a complete Software Bill of Materials (SBOM) and VEX metadata. They're designed to secure your software supply chain while fitting seamlessly into existing Docker workflows.
