This document is for an older version of Crossplane.

This document applies to Crossplane version v1.17 and not to the latest release v1.18.

Connect Crossplane to Azure to create and manage cloud resources from Kubernetes with the Upbound Azure Provider.

This guide is in two parts:

  • Part 1 walks through installing Crossplane, configuring the provider to authenticate to Azure and creating a Managed Resource in Azure directly from your Kubernetes cluster. This shows Crossplane can communicate with Azure.
  • Part 2 shows how to build and access a custom API with Crossplane.

Prerequisites

This quickstart requires:

Install Crossplane

Crossplane installs into an existing Kubernetes cluster.

Tip
If you don’t have a Kubernetes cluster create one locally with Kind.

Install the Crossplane Helm chart

Helm enables Crossplane to install all its Kubernetes components through a Helm Chart.

Enable the Crossplane Helm Chart repository:

1helm repo add \
2crossplane-stable https://charts.crossplane.io/stable
3helm repo update

Run the Helm dry-run to see all the Crossplane components Helm installs.

1helm install crossplane \
2crossplane-stable/crossplane \
3--dry-run --debug \
4--namespace crossplane-system \
5--create-namespace

   1helm install crossplane \
   2crossplane-stable/crossplane \
   3--dry-run --debug \
   4--namespace crossplane-system \
   5--create-namespace

Install the Crossplane components using helm install.

1helm install crossplane \
2crossplane-stable/crossplane \
3--namespace crossplane-system \
4--create-namespace

Verify Crossplane installed with kubectl get pods.

1kubectl get pods -n crossplane-system

Installing Crossplane creates new Kubernetes API end-points. Look at the new API end-points with kubectl api-resources | grep crossplane.

Install the Azure provider

Install the Azure Network resource provider into the Kubernetes cluster with a Kubernetes configuration file.

1cat <<EOF | kubectl apply -f -
2apiVersion: pkg.crossplane.io/v1
3kind: Provider
4metadata:
5  name: provider-azure-network
6spec:
7  package: xpkg.upbound.io/upbound/provider-azure-network:v1.8.0
8EOF

The Crossplane Provider installs the Kubernetes Custom Resource Definitions (CRDs) representing Azure Networking services. These CRDs allow you to create Azure resources directly inside Kubernetes.

Verify the provider installed with kubectl get providers.

1kubectl get providers
2NAME                            INSTALLED   HEALTHY   PACKAGE                                                  AGE
3provider-azure-network          True        True      xpkg.upbound.io/upbound/provider-azure-network:v1.8.0   38s
4upbound-provider-family-azure   True        True      xpkg.upbound.io/upbound/provider-family-azure:v1.8.0    26s

The Network Provider installs a second Provider, the upbound-provider-family-azure provider.
The family provider manages authentication to Azure across all Azure family Providers.

You can view the new CRDs with kubectl get crds.
Every CRD maps to a unique Azure service Crossplane can provision and manage.

Tip
See details about all the supported CRDs in the Upbound Marketplace.

Create a Kubernetes secret for Azure

The provider requires credentials to create and manage Azure resources. Providers use a Kubernetes Secret to connect the credentials to the provider.

This guide generates an Azure service principal JSON file and saves it as a Kubernetes Secret.

Install the Azure command-line

Generating an authentication file requires the Azure command-line.
Follow the documentation from Microsoft to Download and install the Azure command-line.

Log in to the Azure command-line.

az login

Create an Azure service principal

Follow the Azure documentation to find your Subscription ID from the Azure Portal.

Using the Azure command-line and provide your Subscription ID create a service principal and authentication file.

1az ad sp create-for-rbac \
2--sdk-auth \
3--role Owner \
4--scopes /subscriptions/

Save your Azure JSON output as azure-credentials.json.

Tip
The Authentication section of the Azure Provider documentation describes other authentication methods.

Create a Kubernetes secret with the Azure credentials

A Kubernetes generic secret has a name and contents. Use kubectl create secret to generate the secret object named azure-secret in the crossplane-system namespace.

Use the --from-file= argument to set the value to the contents of the azure-credentials.json file.

1kubectl create secret \
2generic azure-secret \
3-n crossplane-system \
4--from-file=creds=./azure-credentials.json

View the secret with kubectl describe secret

Tip
The size may be larger if there are extra blank spaces in your text file.
 1kubectl describe secret azure-secret -n crossplane-system
 2Name:         azure-secret
 3Namespace:    crossplane-system
 4Labels:       <none>
 5Annotations:  <none>

 7Type:  Opaque

Create a ProviderConfig

A ProviderConfig customizes the settings of the Azure Provider.

Apply the ProviderConfig with the command:

 1cat <<EOF | kubectl apply -f -
 2apiVersion: azure.upbound.io/v1beta1
 3metadata:
 4  name: default
 5kind: ProviderConfig
 6spec:
 7  credentials:
 8    source: Secret
 9    secretRef:
10      namespace: crossplane-system
11      name: azure-secret
12      key: creds
13EOF

This attaches the Azure credentials, saved as a Kubernetes secret, as a secretRef.

The spec.credentials.secretRef.name value is the name of the Kubernetes secret containing the Azure credentials in the spec.credentials.secretRef.namespace.

Create a managed resource

A managed resource is anything Crossplane creates and manages outside of the Kubernetes cluster. This example creates an Azure Virtual Network with Crossplane. The Virtual Network is a managed resource.

Tip
Add your Azure Resource Group name. Follow the Azure documentation to create a resource group if you don’t have one.
 1cat <<EOF | kubectl create -f -
 2apiVersion: network.azure.upbound.io/v1beta1
 3kind: VirtualNetwork
 4metadata:
 5  name: crossplane-quickstart-network
 6spec:
 7  forProvider:
 8    addressSpace:
 9      - 10.0.0.0/16
10    location: "Sweden Central"
11    resourceGroupName: docs
12EOF

The apiVersion and kind are from the provider’s CRDs.

The spec.forProvider.location tells Azure which location to use when deploying the resource.

Use kubectl get virtualnetwork.network to verify Crossplane created the Azure Virtual Network.

Tip
Crossplane created the virtual network when the values READY and SYNCED are True.
This may take up to 5 minutes.
1kubectl get virtualnetwork.network
2NAME                            READY   SYNCED   EXTERNAL-NAME                   AGE
3crossplane-quickstart-network   True    True     crossplane-quickstart-network   10m

Delete the managed resource

Before shutting down your Kubernetes cluster, delete the virtual network just created.

Use kubectl delete virtualnetwork.network to delete the virtual network.

1kubectl delete virtualnetwork.network crossplane-quickstart-network
2virtualnetwork.network.azure.upbound.io "crossplane-quickstart-network" deleted
