Chainguard Container for kubernetes-dns-node-cache

Minimal image that acts as a drop-in replacement for the NodeLocal DNSCache image.

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/kubernetes-dns-node-cache:latest

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

Compatibility Notes

This image is a drop-in replacement for the kubernetes-dns-node-cache image commonly used in Kubernetes clusters for DNS caching at the node level. It is functionally equivalent to the upstream image, and switching to the Chainguard image should not require any changes to your existing setup.

Getting Started

You can deploy this image using the nodelocal dns cache Helm chart. Be sure to override the image by setting the following values in a values.yaml file:

image:
  repository: cgr.dev/ORGANIZATION/kubernetes-dns-node-cache
  tag: "latest"

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

Then, deploy the node-local-dns helm chart

helm repo add deliveryhero https://charts.deliveryhero.io/
helm repo update
helm install node-local-dns deliveryhero/node-local-dns -f values.yaml --wait

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

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

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
