Deploy the shopware helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Shopware Helm chart on Azure Managed OpenShift Service using Pulumi, you would need to perform a series of steps:

1. **Create an Azure OpenShift Managed Cluster**: This is the foundational step where an OpenShift cluster is provisioned on Azure. This managed service is a Kubernetes platform, provided by both Microsoft and Red Hat, which simplifies deployment and management of applications.

2. **Deploy the Shopware Helm Chart on the cluster**: After the OpenShift Cluster is up and running, we deploy the Shopware application using a Helm chart. Helm charts are collections of pre-configured Kubernetes resources that can be deployed as a unit.

Below is a TypeScript program, using Pulumi, that accomplishes these two steps:

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

// Step 1: Create an Azure OpenShift Managed Cluster
const resourceGroupName = new azureNative.resources.ResourceGroup("myResourceGroup", {
    location: "eastus", // You can choose a different location
});

const openshiftCluster = new azureNative.redhatopenshift.v20200430.OpenShiftCluster("myOpenShiftCluster", {
    resourceName: "myOpenShiftCluster",
    resourceGroupName: resourceGroupName.name,
    location: resourceGroupName.location,
    // Define the specifics of your cluster here (node count, VM size, etc.)
    // Refer to the API documentation for detailed configuration options.
});

// Wait for the OpenShift cluster to be created before proceeding
const kubeconfig = openshiftCluster.kubeconfig.apply(kc => kc);

// Step 2: Deploy the Shopware Helm Chart on the cluster
// Create a Kubernetes provider instance using the kubeconfig from the OpenShift cluster
const openshiftProvider = new k8s.Provider("openshiftK8sProvider", {
    kubeconfig: kubeconfig,
});

// Deploy the Shopware Helm chart to the OpenShift cluster using the created provider
const shopwareChart = new k8s.helm.v3.Chart("shopwareChart", {
    chart: "shopware",
    // Specify the repository that hosts the Shopware Helm Chart if necessary
    // For example:
    // repo: "https://charts.your-repo.org/",
    values: {
        // Provide configuration values for the Shopware Helm Chart
        // Refer to the Shopware Helm Chart documentation for required values.
    },
}, { provider: openshiftProvider });

// Export the URL of the deployed Shopware app
export const shopwareUrl = shopwareChart.getResourceProperty("v1/Service", "shopware", "status").apply(status => status.loadBalancer.ingress[0].ip);

```

In this program:

- An Azure resource group is created to organize resources related to your project.
- An Azure OpenShift Managed Cluster is initialized within the resource group. You need to specify the cluster's characteristics such as the node count and VM size depending on your workloads.
- A Kubernetes provider is created, which enables Pulumi to communicate with your Kubernetes cluster using the kubeconfig file generated by your OpenShift cluster creation.
- The `shopwareChart` is a Helm chart resource which represents the deployment of Shopware on your Kubernetes cluster. You need to provide the specific chart values that correspond to your Shopware configuration.
- Lastly, the URL for the deployed Shopware service is exported. This URL is generated dynamically when the service is provisioned and uses the load balancer's IP address.

Remember, before running this Pulumi program, you will need to have Pulumi installed and configured with credentials to access your Azure subscription. Also, ensure to replace placeholders with actual values where necessary, such as the Helm chart repository (if it's not from a well-known repository included in Helm's default repo list).

After running the Pulumi program, you should see output in the terminal providing you with the external IP address to access your deployed Shopware application.
