Deploy the hawkbit helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the hawkbit Helm chart on Azure Kubernetes Service (AKS), we will follow the steps below:

1. **Set up an AKS Cluster**: First, we'll create an AKS cluster where our applications will be hosted.
2. **Install the Helm Chart**: Then, we'll deploy the hawkbit helm chart to the AKS cluster.

We will use the following Pulumi resources for this process:
- `azure-native.resources.ResourceGroup`: To create a resource group in Azure where all our resources will be organized.
- `azure-native.containerservice.ManagedCluster`: To create the AKS cluster itself.
- `kubernetes.helm.v3.Chart`: To deploy the helm chart onto the AKS cluster, managed by Pulumi Kubernetes provider.

### Pulumi Program to Deploy hawkbit on AKS

Here is a complete Pulumi program that deploys the hawkbit helm chart on AKS in TypeScript:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as azure from '@pulumi/azure-native';
import * as k8s from '@pulumi/kubernetes';

// Create a resource group
const resourceGroup = new azure.resources.ResourceGroup('myResourceGroup');

// Create an AKS cluster
const aksCluster = new azure.containerservice.ManagedCluster('myAksCluster', {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 1,
        maxPods: 110,
        mode: 'System',
        name: 'agentpool',
        osDiskSizeGB: 30,
        osType: 'Linux',
        vmSize: 'Standard_DS2_v2',
    }],
    dnsPrefix: 'aks-kube',
    enableRBAC: true,
    kubernetesVersion: '1.20.9',
    linuxProfile: {
        adminUsername: 'adminuser',
        ssh: {
            publicKeys: [{
                keyData: 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3b...'
            }]
        }
    },
    nodeResourceGroup: `myAksNodeResourceGroup`,
    identity: {
        type: 'SystemAssigned',
    },
});

// Export the AKS cluster's kubeconfig
export const kubeconfig = pulumi.
    all([aksCluster.name, resourceGroup.name]).
    apply(([clusterName, rgName]) => 
        azure.containerservice.listManagedClusterUserCredentials({
            resourceGroupName: rgName,
            resourceName: clusterName,
        })
    ).
    apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString());

// Create a Kubernetes provider instance that uses our kubeconfig
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: kubeconfig,
});

// Deploy the hawkbit helm chart using the k8s provider
const helmChart = new k8s.helm.v3.Chart('hawkbit', {
    chart: 'hawkbit',
    version: '0.3.0', // Use the version of the chart that you want to deploy
    fetchOpts: {
        repo: 'https://repo.chartcenter.io', // The Helm repository URL where the chart is located
    },
}, { provider: k8sProvider });

// Export the public endpoint of hawkbit
export const hawkbitEndpoint = helmChart.getResourceProperty('v1/Service', 'hawkbit', 'status').apply(status => status.loadBalancer.ingress[0]);
```

This program does the following:
- Imports the required Pulumi modules.
- Creates an Azure Resource Group to hold our AKS cluster.
- Sets up an AKS cluster with the specified Node Pool profile, network settings, and RBAC enabled.
- Retrieves and exports the kubeconfig of the AKS cluster which is required to communicate with the Kubernetes cluster.
- Creates a new Kubernetes Provider which is required by Pulumi to communicate with the AKS cluster using the obtained kubeconfig.
- Deploys the hawkbit helm chart onto the AKS cluster using this Kubernetes provider.
- The public endpoint for the hawkbit service is exported, which can be used to access the hawkbit dashboard once it's deployed and running.

Please make sure to replace the `ssh-rsa` part with your actual public SSH key and adjust the helm chart version to the one you want to use. You'll need to have Pulumi and Azure CLI installed and configured on your machine to use this code. Once applied, you can interact with your AKS cluster using `kubectl` with the outputted kubeconfig. You will be able to access the hawkbit dashboard at the service endpoint URL provided at the end of the deployment process.
