Deploy the azure-advanced-backup helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the `azure-advanced-backup` Helm chart on Azure Kubernetes Service (AKS), you need to perform the following steps:

1. Provision an AKS cluster: You will need a Kubernetes cluster running on AKS. For this purpose, you would use the `azure-native.containerservice.ManagedCluster` resource.
2. Install the Helm chart: Once you have the AKS cluster running, you can deploy Helm charts to it. This can be done using the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider.

Here is how you would use Pulumi with TypeScript to accomplish this:

Firstly, ensure you have Pulumi installed and configured with the appropriate Azure credentials.

Let's start with the code to create the AKS cluster:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";
import * as kubernetes from "@pulumi/kubernetes";
import * as azuread from "@pulumi/azuread";
import * as random from "@pulumi/random";

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

// Create an Azure AD application for AKS
const aksApp = new azuread.Application("aksApp");

// Create a service principal for the Azure AD application
const aksSp = new azuread.ServicePrincipal("aksSp", {
    applicationId: aksApp.applicationId,
});

// Create a random password for the service principal
const aksSpPassword = new random.RandomPassword("aksSpPassword", {
    length: 20,
    special: true,
});

// Create the service principal password
const adSpPassword = new azuread.ServicePrincipalPassword("aksSpPassword", {
    servicePrincipalId: aksSp.id,
    value: aksSpPassword.result,
    endDate: "2099-01-01T00:00:00Z",
});

// Create the AKS cluster
const cluster = new azure_native.containerservice.ManagedCluster("myAKSCluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: "myakscluster",
    linuxProfile: {
        adminUsername: "adminuser",
        ssh: {
            publicKeys: [{
                keyData: "ssh-rsa ...",
            }],
        },
    },
    servicePrincipalProfile: {
        clientId: aksApp.applicationId,
        secret: adSpPassword.value,
    },
});

// Export the cluster's kubeconfig
export const kubeconfig = cluster.kubeConfigRaw;
```

After you have created the AKS cluster, you can use the Pulumi Kubernetes provider to deploy the `azure-advanced-backup` Helm chart to it:

```typescript
// Create a Kubernetes provider instance using the kubeconfig from the AKS cluster
const k8sProvider = new kubernetes.Provider("k8sProvider", {
    kubeconfig: cluster.kubeConfigRaw,
});

// Deploy the azure-advanced-backup Helm chart
const azureAdvancedBackup = new kubernetes.helm.v3.Chart("azure-advanced-backup", {
    chart: "azure-advanced-backup",
    version: "1.0.0", // Use the correct chart version
    repositoryOpts: {
        repo: "http://example.com/charts", // Specify the Helm chart repository URL
    },
}, { provider: k8sProvider });

// Export the Helm chart status
export const helmChartStatus = azureAdvancedBackup.status;
```

In this code block, replace `"http://example.com/charts"` with the actual Helm repository URL where the `azure-advanced-backup` chart is hosted. Also, replace `"ssh-rsa ..."` with your actual SSH public key to access the nodes.

Remember to replace the `chart` and `version` values with the correct ones for the `azure-advanced-backup` chart that you intend to use.

To run this Pulumi program:

1. Save the code to a file with a `.ts` extension, such as `deploy.ts`.
2. Run `pulumi up` from the command line in the same directory as your `deploy.ts` file. Pulumi CLI will perform the deployment described in your code.

Note: The above code is for instructional purposes and assumes that you have set up the necessary Pulumi and Azure configurations. Ensure to review the code and update the parameters as per your requirement before running the program.
