Chainguard Container for cluster-api-vsphere-controller

Kubernetes-native declarative infrastructure for vSphere

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/cluster-api-vsphere-controller: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 cluster-api-vsphere-controller image is compatible with the upstream Cluster API Provider vSphere. This image contains only the minimum set of dependencies needed to run the vSphere infrastructure provider components.

Installation

Prerequisites

• A management cluster with Cluster API core components installed
• clusterctl CLI tool

Initialization

Initialize the vSphere infrastructure provider using clusterctl:

clusterctl init --infrastructure vsphere

You need to create a clusterctl.yaml to configure the VSPHERE_ variables.

Creating a vSphere-based workload cluster

Use the clusterctl CLI tool to generate a workload cluster configuration:

clusterctl generate cluster vsphere-quickstart \
  --infrastructure vsphere \
  --kubernetes-version v1.17.3 \
  --control-plane-machine-count 1 \
  --worker-machine-count 3 > cluster.yaml

Inspect and make any changes:

vi cluster.yaml

Finally, apply the configuration:

kubectl apply -f cluster.yaml

Accessing the workload cluster

kubectl get secret/vsphere-quickstart-kubeconfig -o json \
| jq -r .data.value \
| base64 --decode \
> ./vsphere-quickstart.kubeconfig

Now you can access the workload cluster:

KUBECONFIG=vsphere-quickstart.kubeconfig kubectl get --raw='/readyz?verbose'

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.
