Deploy the squidex helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

Deploying a Helm chart like Squidex on Azure Red Hat OpenShift involves a few steps: provisioning the OpenShift cluster, configuring kubectl to communicate with the cluster, and finally using the Helm chart to deploy the application.

Let's go through the deployment process step by step.

Step 1: Provision an Azure Red Hat OpenShift Cluster

We'll start by creating the necessary cloud resources for our OpenShift cluster. This includes defining the cluster and its characteristics. For this, we will use the azure-native.redhatopenshift.OpenShiftCluster resource from the azure-native provider.

Step 2: Deploy the Squidex Helm Chart on the Cluster

Once the cluster is up and running, we can deploy the Squidex Helm chart to this cluster. For this, we use the kubernetes.helm.sh/v3.Chart resource from the kubernetes provider.

Now, let's translate this into a Pulumi program written in TypeScript:

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

// Step 1: Provision an Azure Red Hat OpenShift Cluster
const resourceGroup = new azure.resources.ResourceGroup('myResourceGroup', {
    location: pulumi.output(azure.containerservice.listOpenShiftVersion({
        location: 'eastus',
    })).apply(versions => versions.sort((a, b) => a.name.localeCompare(b.name))[0].location),
});

const openshiftCluster = new azure.redhatopenshift.OpenShiftCluster('myOpenShiftCluster', {
    resourceGroupName: resourceGroup.name,
    resourceName: 'myCluster',
    location: resourceGroup.location,
    clusterProfile: {
        pullSecret: '<pullSecret>', // You must provide your pull secret
        domain: 'example.com',      // Replace with your domain information
        version: '4.6',             // Specify your OpenShift version
    },
    masterProfile: {
        vmSize: 'Standard_D8s_v3',  // Choose the VM size for the master nodes
        subnetId: '/subscriptions/<subscription-id>/resourceGroups/<resource-group>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<subnet-name>', // Provide the subnet ID where OpenShift cluster will be deployed
    },
    workerProfiles: [
        {
            name: 'worker',        // Define the worker profile
            vmSize: 'Standard_D4s_v3', // Choose the VM size for the worker nodes
            count: 3,              // Number of worker nodes
            subnetId: '/subscriptions/<subscription-id>/resourceGroups/<resource-group>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<subnet-name>', // Provide the subnet ID where OpenShift cluster will be deployed
        },
    ],
    servicePrincipalProfile: {
        clientId: '<clientId>',    // Provide your service principal client ID
        clientSecret: '<clientSecret>', // Provide your service principal client secret
    },
});

// Step 2: Deploy the Squidex Helm Chart on the OpenShift cluster
const squidexChart = new k8s.helm.v3.Chart('squidex', {
    chart: 'squidex',
    version: '4.6.0', // Use the appropriate chart version
    fetchOpts: {
        repo: 'https://charts.squidex.io', // Squidex Helm repository
    },
}, { provider: new k8s.Provider('k8s', { kubeconfig: openshiftCluster.kubeconfig }) });

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

Make sure to replace the placeholder values with actual values applicable to your environment, such as your pull secret, domain, subscription ID, resource group, virtual network name, subnet name, and service principal details.

This Pulumi program will set up the Azure Red Hat OpenShift cluster and deploy the Squidex application on it. Once you run it with pulumi up, you'll have a Squidex instance running on Azure.

Please Note: Provisioning Azure Red Hat OpenShift and deploying complex applications like Squidex may have associated costs. Additionally, for this program to run, you need to have the Azure CLI installed and configured with the required permissions, and the Pulumi CLI must be installed and configured to communicate with Azure. Ensure you have sufficient permissions to create and manage the Azure Red Hat OpenShift clusters and Helm charts on Kubernetes.

The export at the end outputs the kubeconfig necessary to interact with your Kubernetes cluster using kubectl. You can then proceed to manage your Squidex instance or deploy additional services as needed.

If you need further information on the specific properties that can be set for each resource, you would refer to the official Pulumi documentation for Azure Red Hat OpenShift and the Helm Chart.
