Chainguard Container for local-volume-provisioner

Static provisioner of local volumes

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/local-volume-provisioner:latest

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

Usage

To be able to test the local volume provisioner, you need to have a Kubernetes cluster running. You can use k3d to create a local cluster.

Create a local cluster

k3d create cluster

Deploy the local volume provisioner

# creates the necessary StorageClass
kubectl apply -f kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/sig-storage-local-static-provisioner/master/deployment/kubernetes/example/default_example_storageclass.yaml

# creates the local volume provisioner
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/sig-storage-local-static-provisioner/master/deployment/kubernetes/example/default_example_provisioner_generated.yaml

# changes the provisioner image to the one you want to test
kubectl set image daemonset/local-volume-provisioner provisioner="cgr.dev/chainguard/local-volume-provisioner:latest"

Please ensure that the local volume provisioner is running before moving to the next step:

kubectl rollout status daemonset/local-volume-provisioner --timeout=120s

So, if everything is running, you should shell/exec into the nodes and do the following:

# Get server and worker node names from k3d, filtering by role
node_names=$(k3d node list -o json | jq -r '.[] | select(.role == "server" or .role == "agent") | .name')

# Loop over each node name and execute the commands
for node in $node_names; do
    echo "Configuring node: $node"

    # Create directory
    docker exec $node mkdir -p /mnt/fast-disks/vol1

    # Mount tmpfs
    docker exec $node mount -t tmpfs vol1 /mnt/fast-disks/vol1

    echo "Configuration complete for node: $node"
done

Once you have the local disks mounted, you should see the PVs created:

kubectl get pv

That's it! You have the local volume provisioner running and managing the local disks on your cluster.

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:

• 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 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.
