Compatibility Notes

Where possible, the sriov-network-device-plugin Chainguard Image is built for compatibility with the official SR-IOV Network Device Plugin image.

Getting Started

The SR-IOV Network Device Plugin facilitates the use of SR-IOV-capable network devices in Kubernetes clusters, enabling high-performance networking for your workloads.

If you're exploring the usage of sriov-network-device-plugin for the first time, bear in mind that when deploying on a virtual machine like an EC2 instance or a Google Cloud VM these environments often expose only virtual functions (VFs), not physical functions (PFs).

The upstream documentation assumes you have access to PFs and uses the SR-IOV type net-attach-def. However, for it to function properly, it requires access to the PFs, which is typically available only on bare-metal instances. Therefore, we recommend using a bare-metal instance, such as those offered by IBM Cloud, for full functionality. Alternatively, on VMs, consider using the Host Device CNI, which allows VFs to pass through without requiring direct access to the PFs.

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
