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

Question

Pulumi · Accepted Answer

To deploy the Saleor Helm chart on Azure Kubernetes Service (AKS), you'll need to complete a few high-level steps:

1. Set up an AKS cluster.
2. Install Helm on your local machine (Helm is a package manager for Kubernetes, which allows you to deploy applications using templates called charts).
3. Add the Saleor Helm chart repository to Helm.
4. Deploy Saleor to your AKS cluster using the Helm chart.

Below is a Pulumi program in TypeScript that sets up an AKS cluster. We'll be using the `azure-native` Pulumi provider because it provides native Azure resource management within Pulumi.

We'll be defining two main resources here:

- An AKS cluster using the `ManagedCluster` resource.
- A `KubernetesCluster` resource which abstracts the `ManagedCluster` to work with Kubernetes related Pulumi resources.

To deploy the Saleor Helm chart, you'll additionally need to use the `Chart` resource from Pulumi's Kubernetes provider. However, this requires that you have Helm and kubectl installed and configured on your local machine to complete the deployment.

Here is the initial Pulumi program that sets up the AKS cluster:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure";
import * as k8s from "@pulumi/kubernetes";

// Create an Azure Resource Group
const resourceGroup = new azure.core.ResourceGroup("myResourceGroup", {
    location: "West US",
});

// Create an AKS cluster
const cluster = new azure.containerservice.KubernetesCluster("myAksCluster", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    agentPoolProfiles: [{
        count: 2,
        maxPods: 110,
        mode: "System",
        name: "agentpool",
        nodeLabels: {},
        osDiskSizeGb: 30,
        osType: "Linux",
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: "myaksdns",
    linuxProfile: {
        adminUsername: "adminuser",
        sshKey: {
            keyData: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC...",
        },
    },
    servicePrincipal: {
        clientId: "clientId",
        clientSecret: "clientSecret",
    },
    kubernetesVersion: "1.18.14",
    roleBasedAccessControl: { enabled: true },
    tags: {
        environment: "production",
    },
});

// Output the kubeconfig
export const kubeconfig = cluster.kubeConfigRaw;

```

In this program:
- We first create a resource group to hold all our Azure resources.
- Then we define an AKS cluster with a system node pool (VM that hosts the pods) with desired properties such as size and number of VMs.
- We enable role-based access control for the cluster for security best practices.
- Finally, we output the raw kubeconfig string, which you would use with kubectl to interact with your AKS cluster.

After applying this Pulumi program (which sets up your AKS cluster), you would proceed to the following Helm commands on your local machine to deploy the Saleor chart to your AKS:

```bash
# First, ensure Helm is installed, and then add the Saleor Helm repository
helm repo add saleor https://saleor.github.io/charts/
helm repo update

# Now, deploy Saleor using the chart. Replace the 'my-namespace' with the desired Kubernetes namespace
helm install my-saleor saleor/saleor --namespace my-namespace --create-namespace
```

Please replace placeholder values with the actual SSH key, clientId, and clientSecret required to authenticate with Azure.

Remember that this Pulumi program is an infrastructure definition for provisioning the AKS cluster which Saleor will reside upon. The deployment of Saleor using the Helm chart is a post-infrastructure provisioning step that will communicate with the Kubernetes API.

This is a starting point for provisioning an AKS cluster suitable for hosting the Saleor application. Application-specific configurations in the form of Helm values would need to be defined based on Saleor's requirements and your environment specifics.
