Deploy the mautrix-instagram helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the mautrix-instagram Helm chart on an Azure Managed OpenShift Service, we must perform the following steps:

Create an Azure Red Hat OpenShift (ARO) cluster: This is a managed OpenShift service provided by Microsoft. We'll use the azure-native.redhatopenshift.OpenShiftCluster resource to create the cluster.
Install the Helm chart on the ARO cluster: We'll use the kubernetes.helm.v3.Chart resource from the Kubernetes provider to deploy the Helm chart.

Here's what the Pulumi program might look like, with detailed explanations throughout.

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

// Step 1: Create the Azure Red Hat OpenShift cluster.
// Note: You may need to customize the following resource properties based on your specific requirements,
// such as location, resource group, and OpenShift cluster properties.
const openshiftCluster = new azure.redhatopenshift.OpenShiftCluster('openshiftCluster', {
    // Remember to replace `<resource_group_name>` with the desired Azure resource group name.
    resourceGroupName: '<resource_group_name>',
    // Replace `<cluster_name>` with your desired OpenShift cluster name.
    resourceName: '<cluster_name>',
    location: azure.Locations.WestUS, // Choose the appropriate Azure location.
    clusterProfile: {
        domain: '<domain_name>', // Replace with your domain.
        version: '<openshift_version>', // Specify the OpenShift version.
        pullSecret: '<pull_secret>', // Provide your pull secret for OpenShift.
        // The resourceGroupId property should reference an existing resource group or provide the name for a new one.
        resourceGroupId: pulumi.interpolate`/subscriptions/${azure.config.subscriptionId}/resourceGroups/<resource_group_name>`,
    },
    masterProfile: {
        vmSize: 'Standard_D8s_v3', // Choose an appropriate VM size.
        // Replace `<subnet_id>` with your subnet resource ID where the master nodes will run.
        subnetId: '<subnet_id>',
    },
    networkProfile: {
        podCidr: '10.128.0.0/14', // Define the Pod network CIDR.
        serviceCidr: '172.30.0.0/16', // Define the Service network CIDR.
    },
    // Replace `<client_app_id>`, `<server_app_id>`, `<aad_tenant_id>` with AAD application and tenant details.
    aadProfile: {
        // Client App ID used by the OpenShift cluster.
        clientAppID: '<client_app_id>',
        // Server App ID used by the OpenShift cluster.
        serverAppID: '<server_app_id>',
        tenantID: '<aad_tenant_id>',
    },
    // For simplicity, the worker profile is defined inline. Customize it as needed.
    workerProfiles: [{
        name: 'worker', // Name the worker profile.
        vmSize: 'Standard_D4s_v3', // Choose an appropriate VM size.
        // Replace `<worker_subnet_id>` with your subnet resource ID for the worker nodes.
        subnetId: '<worker_subnet_id>',
        count: 3, // Set the desired number of worker nodes.
    }],
});

// Step 2: Deploy the Helm chart in the newly created ARO cluster.
// Create a Kubernetes provider instance that uses the kubeconfig of our ARO cluster.
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: openshiftCluster.kubeconfig.rawData,
});

// Now we can deploy the mautrix-instagram Helm chart on the cluster.
const mautrixInstagramChart = new k8s.helm.v3.Chart('mautrixInstagramChart', {
    chart: 'mautrix-instagram', // The name of the chart.
    version: '<chart_version>', // Specify the chart version.
    fetchOpts: {
        repo: 'https://mau.dev/maubot/mautrix-instagram/helm', // The Helm chart repository URL.
    },
    values: {
        // Supply any values required by the chart here.
    },
}, { provider: k8sProvider });

// Export the cluster's kubeconfig.
export const kubeconfig = openshiftCluster.kubeconfig.rawData;

Explanation:

The azure.redhatopenshift.OpenShiftCluster resource creates the Azure Managed OpenShift cluster with your desired configuration. It's important to customize properties such as the resource group name, cluster name, domain, and OpenShift version, as well as the size and subnet IDs for master and worker nodes as per your requirements.
The k8s.helm.v3.Chart resource deploys the specified Helm chart into your OpenShift cluster. You will need to specify the chart name and version, along with the repository containing the chart, and any necessary values that your chart requires for configuration.
The k8s.Provider resource configures Pulumi to use the kubeconfig file from the created OpenShift cluster, thereby directing subsequent Kubernetes-related resources to deploy to this cluster.

Now that you have the Pulumi program, you should replace placeholders like <resource_group_name>, <cluster_name>, <domain_name>, <pull_secret>, <subnet_id>, <client_app_id>, <server_app_id>, and <aad_tenant_id> with actual values relevant to your Azure and OpenShift setup.

The resulting kubeconfig is exported so that you can use kubectl or other Kubernetes tools to interact with your cluster after Pulumi has finished deploying it.

After you've replaced the placeholder values and ensured you have set up your Azure credentials for Pulumi to use, you can run this Pulumi program to deploy your OpenShift cluster and the mautrix-instagram Helm chart.
