1. Deploy the mautrix-facebook helm chart on Azure Kubernetes Service (AKS)


    To deploy the mautrix-facebook Helm chart on Azure Kubernetes Service (AKS), we need to perform the following steps:

    1. Provision an AKS cluster on Azure.
    2. Install the Helm chart mautrix-facebook on the created AKS cluster.

    We will use Pulumi's azure-native and kubernetes providers. The azure-native provider is responsible for creating resources that reside in Azure, such as the AKS cluster itself. The kubernetes provider, particularly the helm.sh/v3 resource, enables us to work with Helm charts directly.

    First, we'll create an AKS cluster using azure-native resources. After the cluster is provisioned, we will configure the Kubernetes provider to target this newly created cluster and then use the helm.v3.Chart resource to deploy the mautrix-facebook Helm chart.

    Here is the Pulumi program written in TypeScript that accomplishes the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provisioning an Azure Kubernetes Service (AKS) cluster. // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Create an AKS cluster const cluster = new azure_native.containerservice.KubernetesCluster("myAKSCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, // Define the properties for the AKS cluster // (include settings such as size, number of nodes, etc. as needed) agentPoolProfiles: [{ count: 1, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: "myaksdns", enableRBAC: true, kubernetesVersion: "1.18.14", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "<SSH_PUBLIC_KEY>", }], }, }, nodeResourceGroup: `MC_azure-native-go_${pulumi.getStack()}`, // Define service principal or use managed identity as needed }); // Export the Kubeconfig export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => { return azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }). apply(creds => { const encoded = creds.kubeconfigs[0].value; return Buffer.from(encoded, 'base64').toString(); }); // Step 2: Installing the 'mautrix-facebook' Helm chart on the AKS cluster. // Create a Kubernetes provider instance that uses our kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the mautrix-facebook Helm chart const mautrixFacebookChart = new k8s.helm.v3.Chart("mautrix-facebook", { chart: "mautrix-facebook", // Replace <repo> with the Helm repository that contains the chart fetchOpts: { repo: "https://<helm-chart-repo>", }, // Define values for the Helm chart as needed values: { // Custom values for the Helm chart... }, }, { provider: k8sProvider }); // Finally, we could export some of the required properties that would be necessary // to interact with and access our application. // // For example, to get information on how to access the `mautrix-facebook` service, // we could look up the service object and export the necessary details like // the load balancer IP or the DNS name.

    Replace <SSH_PUBLIC_KEY> with your SSH public key that will be used to access AKS cluster nodes securely and <helm-chart-repo> with the actual Helm repository URL where the mautrix-facebook chart is located. For the values section, you may need to add any additional required configurations that the mautrix-facebook Helm chart needs to work correctly.

    Please note that the above kubeconfig is sensitive and should be handled securely. In this example, it is exported for easier access to the cluster, but in a real-world situation, it should be managed carefully.

    To run this Pulumi program, install Pulumi and configure the Azure CLI with credentials to deploy to your Azure account. Then, run the typical Pulumi commands to create a new stack, review the changes, and apply them to create the resources:

    pulumi stack init dev pulumi up

    Remember that Pulumi is a powerful tool that enables you to describe your infrastructure as code. This means that it will keep track of all these resources for you, and you can modify, update, or delete them as needed, right from the code.
