Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/kube-logging-operator-node-exporter:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility

This image is compatible with the ghcr.io/kube-logging/logging-operator/node-exporter image and can be used as a drop-in replacement in existing logging-operator deployments.

Usage

This image contains a custom runner-based Prometheus node exporter that is specifically designed for use with the kube-logging logging-operator. The logging-operator is a Kubernetes operator that simplifies log collection, processing, and forwarding in Kubernetes clusters using Fluent Bit, Fluentd, and other logging components.

Integration with Logging Operator

The kube-logging-operator-node-exporter is typically deployed as part of the logging-operator's monitoring stack to provide node-level metrics for logging infrastructure monitoring. It extends the standard Prometheus node exporter functionality with custom metrics and configurations tailored for logging workloads.

Deployment

This image is designed to be deployed as a DaemonSet in Kubernetes clusters where the logging-operator is running. It should be used in conjunction with:

• The kube-logging logging-operator
• Prometheus for metrics collection
• Grafana or similar tools for metrics visualization

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.
