Installation

Install via helm

Install the EBS CSI driver via the official Helm chart, enabling the volume-modify feature that enable the sidecar controller into the CSI driver controller Deployment, via the Helm value controller.volumeModificationFeature.enable.

Set the volumemodifier sidecar controller image to the Chainguard one, via the Helm values sidecars.volumemodifier.image.repository and sidecars.volumemodifier.image.tag.

Please find an example of values below:

sidecars:
  volumemodifier:
    image:
      repository: cgr.dev/chainguard/aws-volume-modifier-for-k8s
      tag: latest
controller:
  volumeModificationFeature:
    enabled: true

Below is an example, of how to use the helm chart, using both the EBS CSI driver and Volume Modifier Chainguard images.

Add the helm repo:

helm repo add aws-ebs-csi-driver https://kubernetes-sigs.github.io/aws-ebs-csi-driver/
helm repo update

Install the chart:

helm upgrade --install aws-ebs-csi-driver --namespace kube-system aws-ebs-csi-driver/aws-ebs-csi-driver \
  --set controller.volumeModificationFeature.enabled=true \
  --set sidecars.volumemodifier.image.repository=cgr.dev/chainguard/aws-volume-modifier-for-k8s \
  --set sidecars.volumemodifier.image.tag=latest \
  --set image.repository=cgr.dev/chainguard-private/aws-ebs-csi-driver \
  --set image.tag=latest

Installation via EKS add-on

EKS supports installation of the ebs-csi-driver as an EKS add-on. There are instructions in the upstream documentation.

If you've chosen this installation method, keep in mind that you cannot specify a custom image whilst installing via EKS add-on.

You'll need to patch the ebs-csi-controller deployment to use the Chainguard image, however this is a step you'll need to repeat each time that you re-deploy or upgrade the version via EKS add-ons.

Volume modification

To modify volumes with annotations as expected by the volumemodifier EBS CSI driver's sidecar controller, please refer to the official documentation.

Supported annotations on PersistentVolumeClaims are:

  • ebs.csi.aws.com/volumeType
  • ebs.csi.aws.com/iops

For instance, you can set and update dynamically those attributes on a PersistentVolumeClaim like below:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ebs-claim
  annotations:
    ebs.csi.aws.com/volumeType: "io2"
    ebs.csi.aws.com/iops: "4000"
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: ebs-sc
  resources:
    requests:
      storage: 100Gi

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.
