Chainguard Container for dask-kubernetes

Native Kubernetes integration for Dask

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/dask-kubernetes:latest

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

Compatibility Notes

Chainguard's Dask Kubernetes image is comparable to the dask/dask-kubernetes-operator image maintained by Dask. Like most of Chainguard's container images, the Dask Kubernetes image was designed for minimalism and does not include things like a shell or package manager.

Getting Started

Install the operator

helm repo add dask https://helm.dask.org
helm install dask-k8s-operator dask/dask-kubernetes-operator \
  --set image.name=cgr.dev/ORGANISATION/dask-kubernetes \
  --set image.tag=latest \
  --create-namespace -n dask-operator

Verify its running: 
`kubectl get pods -n dask-operator`

To get started with a dask cluster and scale it run this python snippet:

from dask_kubernetes.operator import KubeCluster cluster = KubeCluster( name="my-dask-cluster", image="ghcr.io/dask/dask:latest" ) cluster.scale(10)

You can see the dask worker nodes created above

kubectl get daskcluster -n default kubectl get pods -l dask.org/cluster-name=my-dask-cluster

## What are Chainguard Containers?

[Chainguard Containers](https://www.chainguard.dev/containers?utm_source=readmes) 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](https://edu.chainguard.dev/open-source/wolfi/overview?utm_source=readmes), our Linux _[undistro](https://edu.chainguard.dev/open-source/wolfi/overview/#why-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](https://edu.chainguard.dev/chainguard/chainguard-images/working-with-images/retrieve-image-sboms/?utm_source=readmes) attesting to the provenance of all artifacts within the image
* [Verifiable signatures](https://edu.chainguard.dev/chainguard/chainguard-images/working-with-images/retrieve-image-sboms/) provided by [Sigstore](https://edu.chainguard.dev/open-source/sigstore/cosign/an-introduction-to-cosign/?utm_source=readmes)
* Reproducible builds with Cosign and apko ([read more about reproducibility](https://www.chainguard.dev/unchained/reproducing-chainguards-reproducible-image-builds?utm_source=readmes))

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.
