Deploy the suitecrm helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the SuiteCRM helm chart on Azure Managed Openshift Service using Pulumi with TypeScript, first, you would need an Azure OpenShift Managed Cluster where SuiteCRM will be hosted. You also need the Helm Chart resource, which allows you to deploy Helm charts within a Kubernetes cluster.

Following these steps will get you to your goal:

1. Create an Azure OpenShift Managed Cluster.
2. Deploy the SuiteCRM helm chart into this cluster.

Below is a comprehensive program that outlines how to perform these tasks using Pulumi. Each part of the code is explained in comments to help you understand the functionality:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";
import * as azuread from "@pulumi/azuread";
import * as random from "@pulumi/random";

// Create a new resource group to contain all the resources
const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup");

// You will need to create an Active Directory application for your OpenShift cluster
const adApp = new azuread.Application("openshift-app", {
    displayName: "OpenShift",
});

// Then create a service principal for the above AD application
const adSp = new azuread.ServicePrincipal("openshift-sp", {
    applicationId: adApp.applicationId,
});

// Next, create a random password for the service principal.
const password = new random.RandomPassword("password", {
    length: 20,
    special: true,
});

// You then create a service principal password
const adSpPassword = new azuread.ServicePrincipalPassword("openshift-sp-password", {
    servicePrincipalId: adSp.id,
    value: password.result,
    endDate: "2099-01-01T00:00:00Z",
});

// Now let's create the OpenShift Managed Cluster
// Replace placeholder values with your own settings where necessary
const managedCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    openShiftVersion: "v4.3", // specify your desired OpenShift version
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        name: "master", // name for the master pool profile
        count: 3, // number of masters in the cluster
    },
    agentPoolProfiles: [{
        name: "agentpool", // name for the agent pool profile
        count: 3, // number of agents in the cluster
        vmSize: "Standard_D4s_v3", // VM size for the agents
    }],
    authProfile: {
        identityProviders: [{
            name: "AzureAD",
            provider: {
                kind: "AADIdentityProvider",
                clientId: adApp.applicationId,
                secret: adSpPassword.value,
                tenantId: pulumi.output(azure.core.getClientConfig()).tenantId,
            },
        }],
    },
    // Other necessary fields can be added accordingly
});

// Create an instance of Pulumi Kubernetes Provider pointing to the
// newly created Azure OpenShift cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: managedCluster.config.rawConfig,
});

// Finally, use the Helm Chart resource to deploy SuiteCRM
const suitecrm = new k8s.helm.v3.Chart("suitecrm", {
    chart: "suitecrm",
    // This should be the repository where the SuiteCRM chart is located
    // For example, if the chart is in Bitnami's Helm repository, you would use:
    // repo: "https://charts.bitnami.com/bitnami",
    // Ensure the correct repository is referenced
    values: {
        // Adjust these settings according to your SuiteCRM Helm chart configuration requirements
        mariadb: {
            db: {
                name: "suitecrm",
            },
            rootUser: {
                password: "secretpassword",
            },
        },
        // ... include other necessary values
    },
}, { provider: k8sProvider }); // make sure to pass the created k8s provider

// Export the public IP to access SuiteCRM
export const suitecrmUrl = suitecrm.getResourceProperty("v1/Service", "suitecrm", "status")
    .apply(status => status.loadBalancer.ingress[0].ip);
```

Here's an explanation of what each part of the code does:

1. **Resource Group**: This is where all the Azure resources for this instance of the application will reside.

2. **Active Directory Application & Service Principal**: This provides the necessary identity for the OpenShift cluster to interact with other Azure services under the permissions granted to this identity.

3. **OpenShift Managed Cluster**: This resource represents the OpenShift Cluster where we intend to deploy SuiteCRM. We define the cluster profiles and the networking settings.

4. **Kubernetes Provider**: This uses the OpenShift cluster's kubeconfig to allow Pulumi to communicate with our Kubernetes cluster.

5. **SuiteCRM Helm Chart**: This part of the code deploys SuiteCRM using a Helm Chart. You provide the chart name and the necessary Helm values according to the Helm chart's requirements.

6. **suitecrmUrl Export**: Once the deployment is complete, this line allows you to get the public IP where SuiteCRM will be accessible.

After you have this code, initialize a Pulumi project and place this code in the project's main TypeScript file (usually `index.ts`). Make sure your Pulumi CLI is logged in and your Azure credentials are set up correctly.

Please note that it's essential to replace placeholder values (like the VM size and AD client ID) with your own specific values. Additionally, certain security best practices, such as storing sensitive information in secrets, are omitted here for brevity but should be implemented in a production setting.
