Deploy the matrix-synapse-admin helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `matrix-synapse-admin` Helm chart on Azure Managed OpenShift Service using Pulumi, you'll follow these steps:

1. **Set up an OpenShift Managed Cluster**: You will use Pulumi's `azure-native` provider to configure and provision an Azure OpenShift Managed Cluster.
2. **Install the Helm Chart**: Using Pulumi's `kubernetes` provider, you will deploy the `matrix-synapse-admin` Helm chart onto the provisioned OpenShift cluster.

Below is a detailed Pulumi program written in TypeScript that demonstrates these steps. The comments within the code will help you to understand how each part of the process works.

Keep in mind that before running this Pulumi program, you must have installed Pulumi CLI, logged into your account through it, and set up the correct Azure credentials so Pulumi can manage resources within your Azure subscription.

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

const name = 'matrix-synapse-cluster';
const location = 'West Europe'; // Azure region where the resources will be situated.

// Create an Azure resource group for our cluster
const resourceGroup = new azure_native.resources.ResourceGroup('myResourceGroup', {
    resourceGroupName: name,
    location: location,
});

// Deploy the OpenShift Managed Cluster
const openshiftCluster = new azure_native.containerservice.OpenShiftManagedCluster('myOpenShiftCluster', {
    resourceName: name,
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: '3.11', // Specify the OpenShift version
    // This is a simplified configuration for this example.
    // For production usage, you should configure authentication, network, etc.
    masterPoolProfile: {
        name: 'master',
        count: 3,
        vmSize: "Standard_DS3_v2",
    },
    agentPoolProfiles: [{
        name: 'default',
        role: 'Compute',
        count: 3,
        vmSize: "Standard_DS3_v2",  // Example VM size.
    }],
});

// When the cluster is ready, it provides a kubeconfig. We use this to configure our Kubernetes provider.
const creds = pulumi.all([openshiftCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) =>
    azure_native.containerservice.listOpenShiftManagedClusterUserCredentials({
        resourceName: clusterName,
        resourceGroupName: rgName,
    }));

// The cluster provides a kubeconfig file that we can use to interact with the cluster.
const kubeconfig = creds.kubeconfigs[0].value.apply(value => Buffer.from(value, 'base64').toString());

// Now that we have our kubeconfig, we can create a Pulumi Kubernetes provider.
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: kubeconfig,
});

// Using the Kubernetes provider, we deploy the matrix-synapse-admin Helm chart.
const matrixSynapseAdmin = new k8s.helm.v3.Chart('matrix-synapse-admin', {
    // Name of the helm chart. Adjust the name if it's different in the Helm repository.
    chart: 'matrix-synapse-admin',
    // Below 'values' can be used to provide configuration to the chart. 
    // Please provide necessary values based on the chart's requirements.
    values: {
        // Place the configuration parameters here, for example:
        // adminUsername: "admin",
        // adminPassword: "secret",
    },
}, { provider: k8sProvider });

// Export the kubeconfig of the cluster
export const kubeConfig = kubeconfig;
// Export the OpenShift Managed Cluster id
export const clusterId = openshiftCluster.id;
```

### Important Notes:

- The `azure-native` provider automatically selects the latest available version if the `openShiftVersion` is not specified. The version included in this example is just indicative.
- The OpenShift cluster master and worker sizes (`vmSize`) should be selected according to your workload and performance requirements.
- The `matrix-synapse-admin` Helm chart name and the `values` parameter within the `k8s.helm.v3.Chart` call must be configured according to the actual chart you intend to deploy. Make sure to provide all necessary values for the matrix-synapse-admin chart. These values are usually found within the Helm chart's `values.yaml` file or in its official documentation.
- This program provisions an OpenShift cluster with a basic configuration. Depending on your actual production needs, you may wish to configure advanced networking, authentication, and other important considerations.
- Security aspects like pod security policies, network policies, role-based access control, and secrets management are critical in real-world applications but are beyond the scope of this introduction.

After understanding the code, you can save this program into a `.ts` file, install the necessary dependencies, and run the program using the Pulumi CLI:

```bash
pulumi up
```

Please ensure you have selected the correct Pulumi stack that corresponds to your Azure environment, and you've logged into the Azure CLI with the credentials that Pulumi will use to provision the resources.
