Chainguard Container for cluster-api-azure-controller-fips

Kubernetes Cluster API provider for Microsoft Azure infrastructure management.

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-azure-controller-fips:latest

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

FIPS Support

The cluster-api-azure-controller-fips Chainguard Image ships with a validated redistribution of the OpenSSL's FIPS provider module. For more on FIPS support in Chainguard Images, consult the guide on FIPS-enabled Chainguard Images on Chainguard Academy

Compatibility Notes

Chainguard's cluster-api-azure-controller image is compatible with the upstream Cluster API Provider Azure. This image contains only the minimum set of dependencies needed to run the Azure infrastructure provider components.

Getting Started

The Cluster API Provider for Azure enables you to create and manage Kubernetes clusters on Microsoft Azure using Cluster API. It provides declarative APIs for provisioning and managing Azure infrastructure resources including Virtual Machines, Virtual Networks, and Load Balancers.

Prerequisites

  • A management cluster with Cluster API core components installed
  • clusterctl CLI tool
  • Microsoft Azure account with appropriate permissions
  • Azure service principal credentials configured

Installation

Initialize the Azure infrastructure provider using clusterctl:

clusterctl init --infrastructure azure

Or manually install using the Chainguard image by applying the InfrastructureProvider resource:

kubectl apply -f - <<EOF
apiVersion: operator.cluster.x-k8s.io/v1alpha2
kind: InfrastructureProvider
metadata:
  name: azure
  namespace: capz-system
spec:
  version: v1.20.2
  configSecret:
    name: capz-manager-bootstrap-credentials
  deployment:
    containers:
    - name: manager
      imageUrl: cgr.dev/ORGANIZATION/cluster-api-azure-controller-fips:latest
EOF

Usage Example

Create an Azure cluster using Cluster API resources:

apiVersion: infrastructure.cluster.x-k8s.io/v1beta1
kind: AzureClusterIdentity
metadata:
  name: azure-identity
spec:
  type: ServicePrincipal
  allowedNamespaces:
    list:
      - azure-infrastructure-system
  clientID: "00000000-0000-0000-0000-000000000000"
  clientSecret:
    name: azure-credentials
    namespace: azure-infrastructure-system
  tenantID: "22222222-2222-2222-2222-222222222222"
---
apiVersion: infrastructure.cluster.x-k8s.io/v1beta1
kind: AzureCluster
metadata:
  name: my-azure-cluster
spec:
  identityRef:
    kind: AzureClusterIdentity
    name: azure-identity
  location: eastus
  resourceGroup: my-cluster-rg
  subscriptionID: "12345678-1234-1234-1234-123456789012"
  networkSpec:
    vnet:
      name: my-cluster-vnet
      cidrBlocks:
      - "10.0.0.0/8"
    subnets:
    - name: control-plane-subnet
      cidrBlocks:
      - "10.0.0.0/16"
      role: control-plane
    - name: node-subnet
      cidrBlocks:
      - "10.1.0.0/16"
      role: node

        diskSizeGB: 50
        managedDisk:

Configuration

The controller requires an Azure service principal with the following permissions:

  • Contributor role on the subscription or resource group
  • Network Contributor role (if managing virtual networks)

Create and configure the credentials secret:

kubectl create secret generic capz-manager-bootstrap-credentials \
  --from-literal=clientSecret="$AZURE_CLIENT_SECRET" \
  --namespace capz-system

kubectl patch secret capz-manager-bootstrap-credentials \
  --namespace capz-system \
  --patch '{
    "data": {
      "clientId": "'$(echo -n "$AZURE_CLIENT_ID" | base64 -w0)'",
      "tenantId": "'$(echo -n "$AZURE_TENANT_ID" | base64 -w0)'",
      "subscriptionId": "'$(echo -n "$AZURE_SUBSCRIPTION_ID" | base64 -w0)'"
    }
  }'

Documentation and Resources

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:

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.
